What Are We Doing Wrong with Biofuels?

My friend sent me this article on how biofuels are responsible for a 75% increase in world food prices. index.php/Politics/Biofuels- Are-Starving-Us My response: This is what happens when you live in denial for 100 years, and establish an infrastructure around a fuel source that doesn't really "exist" (the sun is the only "real" energy source we have, but that's another discussion). When it starts to run out, everything destabilizes, which is what we are seeing. The obvious choice, which is not always the best choice, is to look for the most accessible, drop-in renewable alternative . What are doing wrong with biofuels? 1. We're making the wrong fuels. Ethanol has been the biofuel of choice by many, which is a ridiculous fuel. It takes a lot of energy to distill it, and the resulting fuel has a miserable energy density. There are far better ways to get fuel from plants, unfortunately most are not usable by gasoline cars (s

VW Bluemotion Golf for 2009

What do you get when you combine the winning combination of a smaller (1.6L) common-rail turbodiesel engine with a revised ratio 5 speed transmission, and a particulate filter? 74 MPG, and only 99g/km of CO2, thanks to the 2009 VW Golf Bluemotion . This car still has 104 HP (184lb/ft), which is more torque than some gas compact cars have now- and you can bet that those numbers will all but double with a few basic fuel and air mods. In terms of mileage and emissions, this car puts some hybrids to shame- yet with its simplistic design, it will remain much more affordable (£15,500 starting) than cars with complicated hybrid technology. There is no word as to when this car will be brought to the U.S. (as usual), especially with oil prices dropping again, but at least we can have the comfort of knowing it's out there.
