Comparing today’s cars that get 40 mpg or better to the high-mpg cars of a few decades ago is neither an accurate nor fair comparison.

Supply and demand have kept E85 gas prices low, and politics has played a role.
The T7 Series fuel economy is attributed to the design of the engine. With the SCR technology, the engine “breathes” clean air, instead of re-circulated exhaust gases, allowing the engine to simply do what it’s designed to do: produce maximum power.

First in a series of blog posts which will cover conversion of lawnmowers and small engines from gasoline to propane.
This blog explains how the carbon cycle regulates atmospheric levels of carbon dioxide. The blog also discusses how the burning of fossil fuels has disrupted the carbon cycle which increases the amount of carbon dioxide in the atmosphere.
In this posting we discuss the benefits of converting to renewable energy sources vs. the consequences of continuing to use fossil fuels.
In this posting we discuss how rock weathering controls the level of carbon dioxide in the atmosphere. We also discuss why rock weathering can't remove the excess carbon dioxide in the atmosphere that was generated by our use of fossil fuels.
There are many ways that each of us can lessen our unhealthy dependence on filthy fuels. You can do so in every area of your life, from choices you make regarding your house and home improvements, to food, transportation, and other consumer choices.
We discuss the concept that carbon dioxide released from the burning of fossil fuels is partly responsible for the current atmospheric carbon overload. We also briefly discuss other human activities that contribute to the atmospheric carbon overload.
Wood gas, or wood gasification, is a decades-old renewable energy technology that converts chunks of firewood, wood chips or other cellulosic biomass to power vehicles.
