How do you take a completely carbon free form of transportation and mess it all up? By strapping a jet engine onto a kayak, and then proceeding to race it against a 4X4 Land Rover... thing! Richard Hammond from Top Gear says that the kayak is rubbish without an engine. The inventor of the machine has kayak'ed down a 65 foot vertical drop, so he is probably the perfect person to pilot a machine such as this one, especially considering that this little race takes place in, get this... an ice filled lake in Iceland.

I'm not entirely sure why this race took place, but it fits in just right on Top Gear. They are always pulling off crazy stunts like this one. I have gone kayaking before, and the whole point is to enjoy the scenery while getting in some good upper-body exercise. This defeats the point. If I'm gonna jet ski, I want a jet ski; if I'm gonna kayak, I want to row. As a side note, Hammond has not exactly had the best luck when it comes to vehicles powered by jet engines. This would be better if it was powered by biodiesel! Anyway, I hope you enjoy the video!

Sure, all Funny Cars are a bit different. After all, they are so named 'cause they didn't quite look stock, hence the name "funny", according to the great and all-knowing Wiki. But, this one is even more strange in that it runs on 100 percent canola-based biodiesel, which enables the machine to travel the good old 1,320 in just 6.4 seconds at 250 mph. That is extremely fast in anyone's book.

According to the YouTube video, the fuel is from Milligan Bio-Tech in Canada, and the car is owned by Prairieland Motorsports. Visit their web site and read more about the car here. The yellow paint job calls attention to the canola-based fuel source. You might be reminded of Jay Leno's EcoJet car, which also is powered by biodiesel fuel. I am not going to actually call this car green, of course, but the more people that get interested in alternative fuels the better; if drag racing is a way to make that happen, then I'm all for it. Plus, it's really cool, so it's got that goin' for it, which is nice.

The press and consumers alike are already questioning so-called green cars like the pricey hybrids from Lexus as to just how "green" they really are. The same goes for the Prius, as the well-known debate over whether the "well to wheel" environmental cost is not only just not worth it, but worse than even the "anti-green"-est vehicle than them all, the Hummer H2. We're not really collectively buying that particular argument, but it would be a hard sell to convince anybody that the vehicle in the above video is green in any way. Sure, the e-Jet might have started as a plug-in electric GM EV1, but as soon as the jet engine was attached to the rear end, it lost any and all of its eco-conscious credibility, while undoubtedly picking up some other types of street-cred.
