An interesting development in fuel usage is gas-injected diesel. I first read about it in Fast Company where they were using Hydrogen to halve fuel consumption and double engine power.

A company called Lovato appears to be able to do a similar thing for a regular diesel truck using LPG for about $3000, achieving 20% efficiency gains. Not bad once you factor in diesel’s efficiency compared to petrol (25 > 30%), and especially if you’re using biodiesel.

A Google search turned up some other interesting links:

Cool eco-tech to keep an eye on…

I’d heard about this previously, but there’s been a few mentions of producing biodiesel from algae recently that have piqued my interest. Very, very interesting stuff…

Interesting graphic from the New York Times showing alternative fuel total emission comparisons. Interesting to see how well Biodiesel stacks up.
