Gas/Electric Hybrids, Air Cars in the News
hackshack writes "eCycle is developing a hybrid diesel / electric motorcycle designed to get 180 miles per gallon. The small diesel engine kicks in at speeds over 12mph, and the electric motor handles acceleration. Target retail price is $5,500. They've got a beta test program going as well. Now I can laugh at all those "gas-guzzling" Insight drivers as I zoom by!" Reader clen writes in about the Toyota Prius doing well in a road rally, and fishdan sent in a note about a pure-electric concept car called the Tango. And the air-powered car is getting a little more media attention, too.
I've had a Honda Civic Hybrid for about two months, 4,000 miles. I couldn't be more impressed.
It has enough pickup for the driving most people do. Its more comfortable than my Subaru Forrester, including more leg room. It handles well. Best of all, I average 50.8 miles to the gallon. Yes, there is a MPG gauge. It has a range of over 600 miles per tank of gas and is a Ultra Low Emmissions vehicle.
It charges its own batteries through regenerative breaking and cruising without depressing the gas pedel, e.g. going down hill. The electric engine kicks in for some extra horsepower when you drive uphill or are accelerating. The gas engine is only about 96 horsepower, but that is enought when you are driving a light car on level roads . I drive it through the Green Mountains and it performs very well. It can cruise at 70 mph or more on a highway very easily, though I find I downshift a little more in the Civic than my Forrester for some extra oumph.
I've added a Sirius Satellite radio, so now I can drive coast to coast on five tanks of gas while listening to the same radio station!!!!
Put your environmental money where your environmental mouth is and buy one! I believe congress has just pased a tax credit for people who buy a hybrid.
Go forth and be GREEN!!!!!!!!!!!!
Why?
High pressure containers can be designed to fail safely. Simply put, the majority of the tank is stronger then it needs to be, then create intention weaker "seams". This encourages the tank to tear itself apart rather than disintegrating.
Why is tearing good? Because as the tank tears, the hole get bigger and the trapped gas can expand through a larger hole thereby decreasing the relative pressure. Combined with a kevlar webbing around the tank, and protection in the floor of the vehicle, these tanks are probably safer than petrol cars, simply because you can't burn to death.
For an illustration of this tearing effect, the easiest search is +fireworks + flowerpot. or look for failed oxygen cylinders.
