As we head out the door on our road trip to the 2014 Mother Earth News Fair in Topeka, Kansas, I wanted to give an idea how much energy can be generated at home using biogas using the example of our home biogas digesters we will be exhibiting at the event. Home biogas and solar – both photovoltaic electric and solar thermal – would complement one another quite well. Biogas provides excellent, clean burning fuel for year-round cooking energy and a small amount of stand-by electric, while PV can do the heavy lifting for electric and solar thermal for heating and hot water.

Just as solar panels depend on the amount of available sunlight, the amount of biogas that can be produced depends on the amount of organic waste available. A typical American household with a lawn or garden will generate enough energy to cook three meals a day. Our two cubic meter (525 gallon) home digesters are intended to be fed between 10 and 30 lbs. of mixed waste per day, such as table scraps and garden waste, animal manure, grass clippings and tree leaves. This works out to be between a third and a full 5-gallon bucket per day, depending what temperature they are operated at. The units are fully insulated and have a heat exchanger filled with pet-friendly glycol beneath the digestion chamber intended to connect to an evacuated tube solar heater. Naturally, a wintertime hoop house would help improve performance.

Under the lid is the key to Hestia’s simple operation, indicator lines show when the water level is too high (yellow arrow) and too low (blue arrow). Normal operating water level will be between these two lines. If you cannot see any lines, you know it is time to remove liquid biofertilizer; if you can see two lines, you know to add some water.

This baffle separating the inlet from the digestion chamber serves a further function as a built-in pressure relief system. If gas is allowed to build up for a few days, say, during a family vacation, the gas will push down the water level in the digestion chamber until it “burps” out through the inlet. Eliminating the need for any pressure relief valves that could become clogged and ensuring a failsafe pressure relief.

Recommended Uses

Our company, Hestia Home Biogas, is named after the Greek goddess of the hearth. Hestia was also quite naturally the goddess of the family. Just as it was in ancient times, the kitchen remains the center of American life. Everyone we have ever talked to who loves to cook prefers gas over electric ranges, and cooking without fossil fuels or wood adds a level of enjoyment that really makes mealtime a celebration again. Any LPG stovetop or barbecue can be converted to run on biogas by either removing the jets or drilling out the orifices to allow more air flow. Our units ship with a free double burner stovetop from Puxin of China. The Puxin is specifically jetted for biogas and has the “whirlwind” type burners to provide even heating. puxinstovetop

We are often asked about operating electric generators with biogas. This is where the two cubic meter system has its advantages over a one cubic meter system. The 70 cubic feet of biogas per day, it provides enough cooking fuel for three meals per day, while also allowing enough energy to run a generator to watch a couple of movies, while recharging phones and electronics. For home units we recommend 1 kW (1,000 watt) generators or smaller. It is not going to be enough energy to run a clothes dryer or a chest freezer, so the smaller generators will operate much longer. Any generator will require a fuel-gas conversion kit from US Carburetion or similar supplier for around $200.

We look forward to talking to everybody and meeting the Mother Earth News staff and other exhibitors. As always, any technical questions about our products or biogas in general can be posted on the forum on our website. With your help we can build this forum into a central clearinghouse for home biogas users in North American and Europe.

Many people have attempted DIY biogas projects and become discouraged after they failed to produce flammable gas. With my first blog entry, I would like to start at the beginning. This article does not get into gas yields or what biogas can be used for, it is a basic introduction to the five necessary conditions to create flammable biogas in the first place and – hopefully – encourages a few folks who have failed before to try again.

I can guarantee the reader on my life biogas works, and it works great. The ancient Assyrians used biogas to heat their baths in 3,000 BC, the famous gas lamps of Victorian England were fueled with biogas, Sweden runs all of its city buses with biogas and today there are an estimated 50 million households in China using biogas. There are no technical reasons every home in the world is not already using biogas for cooking energy and some light electric. The failure of any biogas project big or small are a result of violating one or more of these five easy-to-remember steps.

The microscopic organisms that produce biogas, known as Archaea, are among the oldest life forms on Earth. They predate the planet’s oxygen atmosphere — much less oxygen-breathing and CO2-absorbing plant life — by a cool 3.5 billion years. That’s billion with a “B.” Archaea are not bacteria, they are genetically closer to humans and other animals (eukaryotes), and form their own animal kingdom. As the Earth’s atmosphere became predominantly oxygen about 500 million years ago, archaea became isolated in the few remaining airless places, such as stagnant swamps, deep oceans, caves and hot springs, and of course the stomachs of vertebrates. To create biogas, we must recreate the conditions in which Archaea thrive in nature.

5 Steps to Making Homemade Biogas

The following table outlines the five steps to creating flammable biogas and I will get into further detail with each one. Biogas is reproduced in a special airtight tank called an anaerobic digester. The design of the anaerobic digester determines the first three steps.

How To Make Homemade Biogas 

Step 1. Airtight Environment. A Ziploc baggie can be used for an anaerobic digester. The difficulty arises from trying to add fresh material without allowing oxygen into the system. The most common method of creating a continuous flow digester is the “teapot” or “P-trap” shape. Most biogas digesters are some variation of this teapot shape.

Homemade Biogas Gas Storage 

Step 2. Archaea love water. When loading a digester, the water content in the material put in it should be taken into consideration. A head of lettuce, for example, looks very solid to us, however, it is 98% water. Dried rice is only 14% water. Regardless of the size of your digester, the “40-50-10 Rule” is simple rule of thumb to follow to get the correct volume: Forty percent material, fill the rest of the digester with water except for 10% headspace.

Home Biogas Digester Contents 

Step 3. A good analogy to think about regarding temperature and anaerobic digestion is your temperature is like the gas pedal of your car. The more you step on it, the faster your digester will convert waste into gas. However, also just like stepping on the gas pedal, there are consequences for it. The warmer your digester is, the archaea that decompose your waste get more fragile and susceptible to an unexpected crash.

Home Biogas Generator Chart 

Temperature can be controlled a few different ways. In China, digesters are typically buried underground and built much larger than they need to be. This way they can be overloaded in winter months to maintain consistent gas production. Other designs employ a greenhouses or hoop house over them. More advanced systems integrate some kind of heat exchanger, which can be heated with solar collectors. Regardless of your design, avoid using biogas or any other fuel to heat your digester. Make sure energy you use is excess energy on its way to being wasted.

Step 4. Neutral pH is an important parameter in anaerobic digestion, just as it is for aerobic composting. If pH is measured at the inlet, it will be slightly lower than neutral — usually around 5.5 — as fresh material is converted into acids. The pH will neutralize as these acids are converted into methane gas. By the time the liquid biofertilizer comes out the digester, it should be 7. If the pH of the biofertilizer is lower than this, it is an indicator the digester has been over-fed and is at risk to “sour,” or stop working due to low pH. If the pH at the inlet goes below 5.5, it is necessary to add some wood ashes or lime to buffer the digester. A soured digester has no bubble activity and instead of producing gas, instead it draws air into it. The top will be sucked in tightly against the surface of the liquid and if a brewer’s airlock is being used, the water in the airlock will be sucked into the digester. Restarting a soured digester is time consuming, and in most cases it is simpler to dump it out and start over. 

Step 5. Biogas production is best at the same 25:1 C:N ratio as aerobic composting. The reason cattle manure is far and away the most common feedstock for biogas is cattle manure is naturally the perfect 25:1 carbon-to-nitrogen ratio. Cattle manure makes an excellent feedstock to begin experimenting with biogas with. Other wastes need to be combined as a compost pile is.

Best Biogas Materials Chart

After these five steps, it is important to know that for the first 48 hours for a small digester or up to a couple of weeks for a larger system, the digester will only produce carbon dioxide (CO2). Carbon dioxide is of course used in fire extinguishers. When you put a match to the gas to test for flammability, it will be blown out with an audible “hiss” and a wisp of black smoke. As the biogas begins to come on, the hiss and black smoke will be gone and you will smell the distinct “rotten eggs” scent of the hydrogen sulfide (H2S). This odor is the signal to begin capturing your gas, as it is either flammable or soon will be. This “CO2 Phase” has caused many people to abandon DIY projects that might have been flammable if they had waited a short time longer.

Resources

For additional information, a terrific introductory text to the subject of biogas is A Chinese Biogas Manual, available on Amazon and other retailers. This guide is an English version of the same booklet handed out to Chinese villagers to build their home and village scale biogas digesters. Our company, Hestia Home Biogas, offers a biogas science kit, which includes everything necessary to produce a small but useful amount of flammable biogas for classroom demonstrations. Just as the home brewer brews beer or wine to achieve just the right taste, the best way to learn how to make biogas is practice. The rewards will outweigh the difficulties when you light the blue flame of biogas for the first time. With this magic formula you can create clean burning renewable energy wherever you are.

If you want to make biogas, and you like things really, really simple—as simple as possible—Then you should move to the tropics.

Why? It's because the rate of biogas production—all else being equal—depends on the temperature of digestion. Within a certain range, the warmer the digester is, the better. By contrast: Sweater weather? No biogas from an unheated digester. So colder is not nearly as good. Bad, bad, bad, in fact, at least as far as biogas is concerned.

Now why should biogas production be so dependent on temperature? Well, the reason is that heat is just a kind of jittering motion of molecules. And the warmer they are, the faster and further they jitter. You can even see evidence of this if you have enough small particles (pollen, for example?) in a jar of water, and you look really closely. You’ll see them move in a sort of random dance, a jitter… bug? (It’s called Brownian motion. Back in 1905, Einstein proved that atoms existed by drawing certain conclusions based on that motion. You could look it up.)

So when these molecules are banging around, the faster and further they bang, the more likely they are to encounter other molecules, and to break apart and recombine to form new molecules, meanwhile (generally speaking) releasing just a bit of heat. Love at first sight happens more often in the tropics, no? (After all, some folks maintain it’s just chemistry.) Love at first sight, and biogas. In the tropics. Add in Tahiti and buy me a ticket, please.

But hey, I assume you’re like me, minus the beard. To be more specific, I assume you live in the U.S. or maybe Europe. For what concerns us here, it’s much the same, because it’s about climate.

For those of us who are living in a place where, at least some of the year, it actually gets cold enough that long pants, socks, and Pendleton shirts make sense, what that means is that we really can’t expect to put a simple, simple, simple biogas digester in the backyard and have it do very much in the winter. You’ll need insulation. You’ll need a heat source. And of course, as we explained in the series about food waste and biogas (part 1, part 2, and part 3), you’ll need enough of the stuff that makes good biogas.

• 95 degrees Fahrenheit/35 degrees Celsius: 100 percent
• 85 degrees Fahrenheit/30 degrees Celsius: 68 percent
• 75 degrees Fahrenheit/24 degrees Celsius: 46 percent
• 65 degrees Fahrenheit/18 degrees Celsius: 32 percent
• 55 degrees Fahrenheit/13 degrees Celsius: 21 percent
• Colder than 55 degrees Fahrenheit: zero percent

Just to keep it simple so as far as temperature is concerned, we’ll call the rate of biogas production at 95 degrees “100 percent,” and compare other (lower) temperatures to that. Every time Mother Nature drops the temperature by as little as 10 degrees, the rate of the production of biogas also drops, pretty steeply, by about a third. (See the table above)

Now, if you have a garden or farm, then you’re familiar with the USDA Plant Hardiness Zone maps, which revolve mostly around how cold it might get where you live. But at least first draft, what we want to know is how warm it might be for how long, and so for the purposes of biogas, the American Horticultural Society (AHS) Plant Heat Zone Map is what we want.

What this map or these maps tell us, according to the AHS website, is “…the average number of days each year that a given region experiences ‘heat days’—temperatures over 86 degrees (30 degrees Celsius)….”

Eighty six degrees ambient… Is that good enough?

Well, how about this: Let’s assume first of all that you carefully studied The Complete Biogas Handbook. That gave you all the tools you need so that you can design your digester to use one of those really good substrates (like food waste) and to be large enough so that when it’s warm and cozy at 95 degrees, it gives you 150 percent of your daily biogas needs: for cooking or whatever it is that you have in mind.

Well, it turns out that if that if you can get 150 percent of what you want at 95 degrees, then at 85 degrees, the rate of production will peg at just about 100 percent of what you want, just by sheer and astonishing coincidence. So if the average daily outdoor (ambient) temperature is 85 degrees or better, then without heating your digester on such days, you can make all the biogas you need, and maybe even a bit more, assuming you keep feeding your digester what it wants, what it’s designed to consume…. Got the picture?

Now I live in Oregon, between Portland and Salem—just above the 45th parallel—and the AHS map for Oregon tells me that, at very best, I should expect only 30 to 45 days a year with “…temperatures over 86 degrees…”. Right? In other words, if I expect to keep getting at least as much biogas as I had planned to get from my digester, I’d have to heat my digester for 335 days a year! (Ouch. That’s a bit discouraging, hey. Now where’s that Tahiti ticket when I need it?)

My digester would be better off in Florida, as you might expect. (I’d have a better tan as well. It’s a win-win, eh?) West and a little south of Miami there’s an area where I would experience better than 210 days a year of biogas weather, but that still means that I would need to heat the digester for in excess of 150 days a year…. The US isn't very “biogas friendly” in terms of climate, is it?

(Hey. Don’t lose hope now. It will be all right. We’ll get there. Together, if you keep reading.)

In any case, of course, all that AHS Plant Heat Zone stuff is far from the whole story, because you may not have to heat the digester very much even on colder days, particularly with proper insulation and the proper approach.

In fact (spoiler alert), on a day that is 55 degrees, the new digester I am working on (see the picture?) can be heated to 85 degrees using less energy in an hour than you generate as heat just by sitting down and watching internet videos for an hour… Even if you’re not laughing!

Want to learn more? Then keep reading… Part 2 will come along real soon now!

These bungs David has developed cost less than a dollar apiece, and replace purpose-made bungs costing $20 or $30 each. The digester being built as shown here is larger than 2 m3, and the materials cost is less than $350.

 solar panels

One of my clients, Sun Light & Power, a Berkeley green business just sealed a deal with San Rafael-based solar electric finance specialist SolED to do Power Purchase Agreements (PPA) in the State of California. In addition, this partnership enables both companies to be stronger California Benefit Corporations for the State and taxpayers.

As we all know, this means:

• schools municipal buildings
• village halls
• fire departments
• city halls
• other halls of government in the State.

This well needed energy savings or tax monies will enhance the educational budgets of schools; setting that great example needed while reducing government’s overall carbon footprint. Gary Gerber, founder and president of Sun Light & Power also announced that the deal will give both his public sector and his private sector customers better access to a full range of financing options. ; which can now include the PPA contracts to "pay as you go". This also gives the owner of the system (SolEd and/or Sun Light & Power) the tax advantages of the renewable energy tax credits and accelerated depreciation.

“We wanted to enhance our ability to help our clients navigate the complexities of solar energy financing and incentives,” Gerber says. “A strategic partnership was clearly the best way to achieve that goal, but we took our time finding the right match, with people who truly share our customer-centered values.”

“Our mission is to provide host customers with the lowest lifetime cost of energy,” said David Kunhardt, CEO of SolEd. “Sun Light & Power has been delivering quality for repeat customers for decades, and is also a B Corporation, the perfect partner for SolEd.”

Again, this is news worth noting.

How much biogas from how much food waste? In general, that’s the question we left unanswered in that last blog, part 2 in this series. (Here… And part one is here, in case you missed it.)

Well, the rule of thumb is that a biogas digester kept at the proper temperature — body heat, which is 105 degrees Fahrenheit … or at least it is for a cow — will produce its own volume in biogas every day. According to this rule, if your digester is a cubic meter, and you keep it properly warm, you will get a cubic meter of biogas from it, every day. (That’s about 35 cubic feet, and comfortably more than most families will need to cook their lunch and dinner, but not a lot more.)

But that rule of thumb comes from experience with manure-fed digesters. That is, if you have a digester and you’re just putting manure in it, then the rule of thumb applies. But the fact is that different substrates produce different amounts of biogas. Remember when we said that food waste makes great biogas? (No? Well, we did….) You can see the difference by looking at the following chart which I produced, using data published by the Bavarian Association for the Promotion of Solar Energy:

substrates chart

Click on the graph to see a larger version. Source data derived from Solarenergiefoerderverein Bayern e. V., “Biogas– Strom und Wärme aus der Natur”, pg. 9 (here)

Freshly cut grass clippings can ultimately produce better than 1½ cubic feet of biogas per dried pound. By contrast, the same dry weight of cow manure, under the same conditions, will produce less than a quarter of that. If you’re lucky enough to have enough of what the Bavarians call “residual fats,” then the comparable pound will produce 24 times the amount of biogas as the cow manure. So like I said: different substrates produce different amounts of biogas. In spades.

Now, of course, all energy, but most especially small-scale (they call it) alternative energy, biogas included, is situational. It doesn’t matter how fancy/cool some to-be-purchased wind electric system is if you don’t have wind where you are. And you’ll never heat your water with the sun… at night. In the same way, it shouldn’t matter to you how great corn silage is for making biogas if you don’t have any corn silage. And as for “residual fats”— like used cooking oil, maybe?— the biodiesel folks probably have all that stuff snatched up before the fast food places have time to even think about pulling the last dripping French fry out of it.

But these days, almost any of us can get access to wasted food, stuff that gets tossed from places out all over town, restaurants, and cafeterias and grocery stores. Mark my words: A day will come when food waste will be as hard to get as used cooking oil is now. But for the time being, almost any of us can get just about as much as we want.

So again (since I still haven’t told you, right?) how much biogas can you get from your food waste digester?

Well, maybe I did give you the answer: about 4 (or more) times as much per dry pound as you could if you were using cow manure. In general, in other words, take the rule of thumb and multiply by 4.

And how much will you need? Well, what you really need to get detailed answers about your specific situation is more information. For example, to figure out how much biogas you need to heat your house, you need to know a lot about the weather outside, how large the house is, how well insulated, and things like that. That whole process is described in The Complete Biogas Handbook, chapter 28. The book will also tell you how to convert the burners on your stove to run on biogas, the practical details of designing your own digester, how to figure out things like how much hot water you need, how much biogas it will take to heat it, and all the cool stuff you need to know to really make practical use of biogas. Besides, when you visit the site you can find the best free information on the web about how to build any of the four most common home-scale digesters (on the “build” page).

Now, at this juncture, most explanations that I have seen about biogas get a bit coy, and they don’t give you really practical information in a clear form. We’re not going to do that. The chart below is like no other that I have seen in all my years of involvement with this subject.

The chart asumes two critical things: first, that you are digesting food waste, and second, that the digester is at body temp. Given just those two assumptions, it shows you how many 1-gallon buckets of food waste you need to be able to get the outcome you want— and what size of digester you’ll need too. Simple. Clear. Ready? Here it is:

Engine, 100 HP 1600.0 Small engine (genset?), 4 hours/day 6400 160.0 9,600

(For hot water, we figured we would need to raise the temperature from
50° to 130°F, @40% efficiency, using biogas @60% methane.)

If you've been reading along with these blog posts, you'll know that in part 2, we mentioned that we were going to answer what is, for biogas, the ‘holy grail’ question: “Can I run my car on biogas?” Well, look at the chart. The answer seems pretty obvious: sure you can; but you need to get a hold of a couple of hundred one gallon buckets of food waste… every day. (That’s based on the thought that most cars have engines that are larger than 100 HP.)

What? Did you think I'd tell you some fairy tale? Cars are Big, Lumbering, Inefficient Energy Hogs. Does it really make sense that you could power one with three or four buckets of food waste?

If you do the math, you'll see that a standard engine requires about 16 ft3 per HP per hour. And that 100 HP engine? The digester needed to provide 4 daily hours of fuel for it (if kept at body temps) would be the size of an above-ground swimming pool: 20 feet across and 4 feet high. And keep looking. The chart can give you a lot more information like that ... And along those lines, notice that except for running your Range Rover, the biogas you need to provide light, cooking and hot water for an averagefamily can be produced if you can find 6 gallons of food waste a day. Is that a lot or a little?

So I think that's good, yeah? Biogas and food waste. And the folks who end up making food waste into biogas will be doing the rest of us a great big favor, because when that food waste gets put into the landfill, it produces methane there too. The difference is that the methane from the landfill goes into the atmosphere, and there…, well, it’s a very powerful greenhouse gas: it has 38 times the negative impact of carbon dioxide. But when we make biogas (and burn the biogas), all that methane is turned into carbon dioxide… and the impact of the food waste is dramatically reduced. Talk about a powerful way to reduce your carbon footprint: Think biogas.

Be a good guy. Make some food waste into biogas, and then burn the biogas, joyfully. (The first time you see that pale, almost invisble blue flame, you’ll be hooked, for sure.)

I think maybe in the next blog series we’ll say a few things about temperature, a really important parameter in biogas production. And, hey, just because I like you, I’m going to give you an Excel spreadsheet to calculate the effect of temperature on the digestion process. Keep reading...

In mid-2012, we avid do-it-yourselfers, cast a lustful eye on photovoltaic solar for our home.  We reasoned that the sun was there every day – why not capture it’s free, clean, and renewable energy?  The thought enticed us not unlike Raphie in A Christmas Story

Just like Raphie, was enticed by the Red Rider BB gun, but held at bay by the threats of shooting his eye out, we were enticed by shiny solar possibilities with the threats of failing and being made a laughing stock (at best) or becoming a pile of incinerated ash (at worst).  Danger does lurk around every corner for the novice and/or the careless and extreme caution should be the rule.  Being aware of this, we still decided the take the plunge and build the system ourselves. We began the build in January 2013. Six months later, we completed the project successfully and were up and running.

DIY Photovoltaic Solar Power 

Here is a picture of our finished system in front our home. We built an on-ground system for ease of maintenance and the ability to rotate the frames and capture more solar energy at different times of the year.

Advantages of DIY Home Solar Power

By taking on the project ourselves we were able to:

Capture more electricity by designing (manually-driven) automated rotated frames which incorporate full tilt angle variation to track the sun all year

Have on-grid/off-grid capability with the flip of a switch

Capture free renewable energy and help keep the earth cleanDIY Photovoltaic Solar Power

By designing and building the system ourselves we estimate we saved over 70%. Our payback (with incentives included) is a mere 6.2 years. We realized that almost anyone, anywhere will benefit from photovoltaic solar energy. (See NASA charts at this link.)

We are delighted with our photovoltaic system and have written a book entitled DIY Photovoltaic Solar Power for Homeowners. In our book, we’ve included our detailed charts, wiring diagrams, parts lists, and energy analysis. We’re looking forward to sharing details of our system build and design in other blog posts.

One of the worst traits of humankind is our reliance on fossil fuels and the incessant depletion of non renewable resources. There are many alternatives and yet the majority of the world still acquires energy using practices which are causing irreversible damage to the earth, the people, the land, the air and the water. The exploitation of natural resources and reliance on coal powered plants and nuclear energy plants will lead to a dismal future if solution based renewable energy systems are not replaced as the norm.

Introducing Aur Beck

Luckily, individuals like Aur Beck are shedding light on the easy transition to choosing renewable energy. My dear friend, Aur 'da energy mon' Beck, has been immersed in the growing field of renewable energy since he was a teenager. In 1990 at age 15, after independently researching solar energy, Aur moved into a 12 volt,  battery operated camper in his parents’ driveway.

Aur translates as "light" or "to enlighten" in both Hebrew and Latin, a perfect name for a solar energy expert. According to Aur, “reading profusely and consistently tinkering with Renewable Energy (RE) has been a continuous constant throughout my life. Never officially attending school left me time to do in depth study, intern, view, and install renewable energy projects. Of course, working in one of the first United States passive solar schools helped.”

The Power of One

Aur is the president, chief tech, and coordinator of the Renewable Energy Install Network (Green Geek Squad) for Advanced Energy Solutions. Since 1999, he has been putting his knowledge to great use promoting, installing, & educating about renewable energy.

Aur has made significant contributions to Solar Energy in recent years. Aur sheds his light in many ways:

Founder and on the board for both the Illinois Renewable Energy Association and the Southern Illinois Center for a Sustainable Future
Started Oil Addicts Anonymous International
Hosts a weekly radio talk show called Your Community Spirit
AESsolar won the “Missouri Schools Going Solar” contract in 2005 and assisted with the sale and installation of 17 school systems
January 2007, trained presenter for Al Gore’s Climate Project
Based on the vast knowledge base Aur has in the field of renewable energy, he was invited to join the Midwest Solar Training Network (a DOE program) and to become an adjunct professor at Hocking Energy Institute in Logan, Ohio

Aur grew up on the family farm in the heart of the Shawnee National Forest, in an off-the-grid, solar-electric-powered home which makes it very easy to advocate for a life of simpler living, energy efficiency and renewable energy. Aur came up with and definitely lives by Advanced Energy Solutions slogan: We Empower YOU to Get Energized!

Dedication to Sustainable Living

I have been impressed with Aurs dedication to sustainable living and renewable energy since I first met him in 2000. One of Aurs most notable accomplishments in the last few years was being hand selected and invited to teach a semester of Solar PV Design and Installation by Neil Hinton, the Dean of the School of Engineering and Information Technology of the Hocking College Energy Institute in Nelsonville Ohio. This is impressive in light of the fact that Aur hasn’t been through any formal schooling whatsoever. He has no degree but he is a living breathing encyclopedia of all things solar. Aurs ability to confidently teach at a college level with no formal training is very inspiring. Not only does it encourage others to follow their dreams but it also offers a bit of insight into just how powerful it is to be passionate about what you do in life sans a degree.

At the Energy Institute, Aur inspired students by his minds on/ hands on teaching methods. He tested their knowledge initially to try and fill in the knowledge gaps throughout the semester. He gave them useful and practical knowledge which can actually be related to real world applications.

The reason he was selected to teach is due, in part, to him being double NABCEP certified. Helping students in the program taking The NABCEP, (North American Board of Certified Energy Practitioners) Entry Level knowledge test was his primary goal.

Inspiration is cyclical. Renewable energy can reshape the future.
