kashino: (via BMW adds steam engine to car, improves fuel efficiency by 10% | DVICE) —- A steam engine is one of the simplest forms of engines. Heat boils water into steam, and then the steam pushes on a piston or drives a turbine or whatever to do work. Since you can use any source of heat to boil water, in theory you can just duct tape a steam engine onto anything that warms up to a couple hundred degrees and harvest energy from it while cooling it down at the same time. This is all that BMW is doing: the company is adding a small, steam-powered electric generator to an automotive exhaust system that sucks heat out of exhaust gases, boils a fluid into steam, and uses the steam to run an electric generator. —- これはすげえ。BMWが排熱による「コンバインドサイクル発電機」を車に配備したんだって。あのガスコンバインサイクル発電のように、燃料を燃やしてエネルギーを運動に変えたあとの媒体の排熱を利用して、更に発電する手法だそうだ。これにより10%の燃費が向上だそうだ。 なるほど、ハイブリッドエンジンの他にもこういう持続的イノベーションネタはまだまだあるんだね。
