A New Zealand chemist has found a good use for spent yeast normally discarded after brewing beer, Popular Mechanics is reporting (via AutoFocus).
It’s not the first time beer-based ethanol has been used to power cars, but New Zealanders can fill up on 98-octane (!) booze-fuel for a limited time. The mix is 90 percent gas to 10 percent beer ethanol.
(Note: I covered parts of the 2008 Democratic National Convention in Denver and remember the Coors-powered cars in Denver and think it’s the best imaginable use of Coors Light)
I’ve just driven a couple of modern electric cars, the Mitsubishi i-MiEV and the Tesla Model S, and they’re real cars. Actually, the i-MiEV is a perfectly serviceable short-distance commuter and the Model S is the best street car I’ve ever driven, but I was ready to hate both of them a lot, because all my previous experience with EVs had involved growing up in the San Francisco Bay Area in the 1970s and hearing a lot of eat-yer-vegetables talk from earnest green types about how electric cars are good for you, when in fact those cars sucked stringwart-covered pangolin nodules. Then, of course, there are all the flake-O electric conversions from the 1980-2000 era that I’ve seen, a fair number of which appear in self-service wrecking yards as long-abandoned EV conversions are towed out of back yards and driveways. In this series, we’ve seen this EVolve Electrics 1995 Geo Metro and this 1988 Chevrolet Sprint Electric Sport, and there have been others too stripped to be worth photographing. Today we’re going to look at a California-based Ford Ranger that still has just about all its electric running gear. (Read More…)
Now that it’s possible to buy electric cars that actually do what cars are supposed to do, we mustn’t forget the very lengthy era— say 1970 to just a few years ago— during which all manner of optimistic-yet-doomed companies converted various econoboxes into lead-acid-battery-based EVs. Every once in a while, I’ll spot the remains of such an EV at a junkyard; we saw a junked EVolve Electrics 1995 Geo Metro EV conversion last year, and now a different Denver yard has given us this ’88 Sprint “Electric Sport.” (Read More…)
“The only way to break this cycle of spiking gas prices — the only way to break that cycle for good — is to shift our cars entirely, our cars and trucks, off oil,”
So said President Obama during a speech in Illinois, where he outlined a plan to provide $200 million a year for 10 years to a fund that would promote the development of alternative fuel vehicles. The funds would be provided by royalties from oil drilling on the Out Continental Shelf.
Normally, I wouldn’t consider an 18-year-old Suzuki Cultus badged by a now-defunct GM marque to be worthy of inclusion in this series, but this particular example— which I found at my favorite Denver self-service wrecking yard— has been converted to electric power and is thus sort of interesting.

Westport Innovations has just signed a second deal with General Motors to produce light duty natural gas engines, and it’s probably not the last time we’ll be seeing these kind of partnerships forming. Natural gas vehicles have been explored previously on TTAC, but the technology hasn’t been fully explored in-depth, aside from some well-informed comments in various articles.
Compressed natural gas may cost the equivalent of $1.89 per gallon of gasoline, but retrofitting your GMC Sierra or Chevrolet Silverado will cost you $11,000 – and GM still think it will save you money.
Even with gasoline prices reaching higher and higher, and natural gas prices at decade lows, consumers are doing as little as possible to adopt natural gas vehicles. As investment blog Seeking Alpha found out, the answer isn’t so complex.
