Biodiesel conversion specialist Jonathan Goodwin has developed his own methods to reconcile two factors that were once thought impossible to have both ways: Engine power and nature-friendliness.

To prove that, he showed off his H2 Hummer that runs 40 miles per gallon on every fossil fuel alternative in the market- ethanol, hydrogen, biodiesel or natural gas. All of these pollute the environment in low or almost negligible levels.

Goodwin drew his inspiration to create green muscle cars from a fad that hit the mid to late 90s. During those times, electric cars were billed to replace the traditional models of vehicles. However, the models proved to be a short-lived novelty concept. Performance was just incomparable to ordinary vehicles and the electric cars stalled in cold weather. What's more, the smoke these cars were not emitting didn't really go away. They just transferred to the smokestacks of power plants.

"The first electric cars were like golf carts. You really had to be freakin' altruistic to drive one of those things," says Imperium Renewables CEO Marvin Tobias. "Tesla changed that by telling customers 'You can have it all," he adds.

To date, Goodwin has converted 60 H2 Hummers and 100 H1 Hummers are on the way. The results have been so good that his work will be featured in an upcoming "Pimp My Ride" episode on MTV. If you want to have your Hummer converted, however, you better come ready. The whole ordeal costs US$ 24,000 and takes a week to complete.

Here's an interesting contest for you DS lovers to try out.

MTV and Nintendo are holding a contest in which gamers will take pics of themselves playing with the DS in the unlikeliest of places.

What's the prize, you might ask? The chance to actually PLAY your DS in the unlikeliest place on earth: zero-gravity simulated space on board the Zero-G zero gravity plane. That, and they give you two more DS handhelds, $400, and three pairs of new games, but that probably isn't the main draw of the contest if you already own a DS.

As the MTV site announces to its readers,

We can't make your dreams of playing your Game Boy in the primate cage at the Bronx Zoo come true, but we can give you a chance to play your Nintendo DS in a completely weightless, zero gravity environment. Send us a picture of yourself playing handheld games in the most bizarre, exotic or otherwise foolish place, and MTV and Nintendo will give you and a friend the chance to win an expenses-paid trip aboard a ZERO-G zero gravity plane. We'll even throw in some spending cash and a "Travel Lite" gaming pack with two DS Lite units and copies of three games. Think you can stomach it? Send us your best shot and find out.

Good luck to you folks who want to try out. Just don't end up taking a shot while you're hanging by your legs above a pit with wooden spikes and vipers.
