Here is a great article in this months issue of Fast Company.

This 7th grade drop out has taken 90% of GM parts and managed to get 60MPG & 0-60 MPH in less than 5 seconds on a HUMMER H1 and 100 MPG on a Lincoln Continental...

With 90% of the parts coming from the already existing GM parts supplies, and convertions starting at only $5,000 this OLD technology could really catch on....

“Check it out. It's actually a jet engine," says Johnathan Goodwin, with a low whistle. "This thing is gonna be even cooler than I thought." We're hunched on the floor of Goodwin's gleaming workshop in Wichita, Kansas, surrounded by the shards of a wooden packing crate. Inside the wreckage sits his latest toy--a 1985-issue turbine engine originally designed for the military. It can spin at a blistering 60,000 rpm and burn almost any fuel. And Goodwin has some startling plans for this esoteric piece of hardware: He's going to use it to create the most fuel-efficient Hummer in history.

Goodwin, a 37-year-old who looks like Kevin Costner with better hair, is a professional car hacker. The spic-and-span shop is filled with eight monstrous trucks and cars--Hummers, Yukon XLs, Jeeps--in various states of undress. His four tattooed, twentysomething grease monkeys crawl all over them with wrenches and welding torches.

Goodwin leads me over to a red 2005 H3 Hummer that's up on jacks, its mechanicals removed. He aims to use the turbine to turn the Hummer into a tricked-out electric hybrid. Like most hybrids, it'll have two engines, including an electric motor. But in this case, the second will be the turbine, Goodwin's secret ingredient. Whenever the truck's juice runs low, the turbine will roar into action for a few seconds, powering a generator with such gusto that it'll recharge a set of "supercapacitor" batteries in seconds. This means the H3's electric motor will be able to perform awesome feats of acceleration and power over and over again, like a Prius on steroids. What's more, the turbine will burn biodiesel, a renewable fuel with much lower emissions than normal diesel; a hydrogen-injection system will then cut those low emissions in half. And when it's time to fill the tank, he'll be able to just pull up to the back of a diner and dump in its excess french-fry grease--as he does with his many other Hummers. Oh, yeah, he adds, the horsepower will double--from 300 to 600.

"Conservatively," Goodwin muses, scratching his chin, "it'll get 60 miles to the gallon. With 2,000 foot-pounds of torque. You'll be able to smoke the tires. And it's going to be superefficient."

He laughs. "Think about it: a 5,000-pound vehicle that gets 60 miles to the gallon and does zero to 60 in five seconds!"

The numbers are simple: With a $5,000 bolt-on kit he co-engineered--the poor man's version of a Goodwin conversion--he can immediately transform any diesel vehicle to burn 50% less fuel and produce 80% fewer emissions. On a full-size gas-guzzler, he figures the kit earns its money back in about a year--or, on a regular car, two--while hitting an emissions target from the outset that's more stringent than any regulation we're likely to see in our lifetime. "Johnathan's in a league of his own," says Martin Tobias, CEO of Imperium Renewables, the nation's largest producer of biodiesel. "Nobody out there is doing experiments like he is."

"You can feed it hydrogen, diesel, biodiesel, corn oil--pretty much anything but water."
