Whatever it is, it will be measured in dollars and cents. 

For the first time ever, all types of energy will be propelling licensed street bikes, side-by-side, on public roads, in a 100-mile ride.  Are the claims true?  Come see for yourselves.  Is it time to reconsider what we drive?

Gasoline has been the energy of choice for a hundred years. But when 3 out of 4 gallons we use is imported, is “our” supply really ours?  Bugni's web page

I have to add, that I plan to fill these bottles with biologically produced methane and I don't really want to burn the bottles, but feed the catalytic heater with the gas from them.^^

My intention is to combine two things. Electric motors are the most efficient motor available, but they suffer on heavy batteries. In germany, where I live there are standard 11 kg gas bottles for Campers available everywhere. These bottles burnt in a catalytic heater provide some thousand kW each in heat. Instead of using a normal combustion engine i would have a try in combining a catalytic heater with a Seebeck utility that converts temperature differences into electricity. The electricity will feed one or more electric motors that are formed as hubs of the two front wheels of my just imagined vehicle. Thus I combine a high ratio kg/kW with a completely light weight system. I would build this vehicle from bicycle parts as a two seater shopping pickup.

Hey Craig, When we look at the fossil fuel industry (from wells to fuel pumps) it can be overwhelming. With fossil fuels you have to refine for a huge range of what is produced from asphalt and plastics to jet fuel. You make a machine that can do more with less (your freedom machine) then the scale of production for fuel can fall into the scope of cottage industry. Instead of refining fossil crude you would be refining bio-crude. The benefit of such a system is that it can work with our current technology. The internal combustion engine(s) should run on the bio-fuels the same as it runs on fossil fuels (some tweaking may be required). The only thing that changed is where the fuel came from. In our case it was grown in an aquarium rather than discovered in a rock basin. That control gained by growing the fuel means we could narrow the scope of the refinement process. It would be about as difficult to operate as an aquarium. No impact to the food crop industry and by far safer than nuclear. So, what is really the obstacle? If it’s not the technology or the cost, then perhaps it’s just the shift in Paradigm. CM
