Electric Motor vs. Diesel Engine
2009-02-23 17:25:00 Hello, On a boat there are two diesel engines, each 110 Hp, for the main propulsion. Because the boat is only going to be used for inland navigation and the speed of the boat is limited to 60 km/h, the two diesel engines have too much power and consume too much of petrol.

Bicycle with electric motor assist.
2008-04-29 10:39:00 It's not exactly cheap, but it could be a steal anyway. The Electric Motion Systems' E+ electrically assisted bicycle could prove to provide a major improvement in your health, the health of the planet and, of course, the health of your finances. After the initial investment you could improve your health by biking to work instead of driving, you would use much less gas, and subsequently spend less money. The E+'s electric motor is situated in the rear hub and the battery in the front. This could make the bike a little front heavy, but we'll reserve any opinions on its handling until we've had a chance to test drive it. Other things are more obviously smart, like the regenerative braking, which enables the battery to get charged each time the rider brakes, and the the handlebar-mounted LCD display which shows speed, distance traversed, battery level and whether or not cruise control is enabled. It is a hefty USD 3,495:-, but considering the price of gas lately...

Zero X Electric Motorcycle is "cheap" and pretty darn wic
2007-08-04 05:43:00 Looking for something to throw on your truck rack this summer? Well have been, and since I'm an eco geek, the issue is, the last bike to hit the market that was battery powered and had some kick ass features was over 14,000$ well not anymore as the boys over at Zero have produced the first production Motorcycle that's both fast and eco friendly for under 7 grand. Yes, it's still not as cheap as some of us poor boys need it to be but its definitely on it's way towards the "everyone" market. Say hello to the Zero X Electric off-road motorbike, this is a 100% zero emission lithium-ion powered vehicle. With a good bit of power might I add, just over 20 horsepower rockets this 120 pound motorbike to right around 50 miles per hour and a 3 hour battery charge allows it to run for a full 40 miles worth of travel. Now while the horsepower may be equivalent to that of a 250cc gasoline bike, the acceleration is quite a bit different and lot faster than its pollutant rich brother...
