Consider this, ethanol burns stronger and cleaner than gasoline and can be grown within the United States and other nations that have a climate which supports corn or switchgrass. The energy density of Ethanol is substantially less than conventional gasoline (31.1MJ/kg vs 47.1 MJ/kg) but it burns stronger because it’s less volatile (i.e. higher octane) …

Biomass Energy Overview
Biomass is a term that has been popularized to describe a clean source of combustible fuel. It is actually one of the oldest sources of energy known to man but has been overshadowed by oil and other fossil fuels in recent decades. Harvesting biomass energy can consist of burning plants such as corn, switch grass, …

Biofuel Vehicles vs. Electric Vehicles
When it comes to transportation, no battery technology even comes close to the energy density of liquid hydrocarbon fuels. Whether they be derived from ancient or recent biomass, the energy density of hydrocarbon fuels is many times that of even the most advanced battery technology. And energy density is one of the most important metrics …

Can I Use Drinking Alcohol in My Flex Fuel Car?
The other day while pondering the effectiveness and durability of different “clean car” options available on the market, specifically flexfuel cars vs. veggie oil vs. EV, I began considering which fuel type would be the most convenient if the grid went down and suddenly gasoline became unavailable. I’ve heard that up here in Northern California …
