Anyone with enough coin to not concern themselves with fuel prices anyway can throw down $100,000 (or more) for an uber-green Tesla Roadster
, or you can tack a few extra grand onto the price of your next vehicle to ensure it has some sort of hybrid engine
underneath the hood, but MIT researchers are developing yet another alternative to our oh-so-troublesome fuel dilemma without looking to fuel cells. The gasoline / ethanol prototype is about "half the size" of a conventional gas engine, and would only add "about $1,000" to the price of a vehicle -- much less than current battery / gasoline options
. The gasoline and ethanol are housed in separate tanks, with the ethanol "suppressing the spontaneous combustion inside the cylinder," allowing for a "higher compression ratio" and a "30 percent increase" in overall gas mileage. Ford
is currently testing the system with Ethanol Boosting Systems, and while we're unsure how these engineering minds will solve the problem of double-pumping each time you need a fill up, they're reportedly working hard to "minimize any inconvenience to the driver."
