Children Turn Up the Heat in Energy DriveSchoolchildren in an inner-city Birmingham neighbourhood have been getting involved with a project aimed at making people more conscious about energy efficiency.The Birmingham Post (England)
The process of turning heated water into energy was essentially understood by James Watt all the way back in 1765. Heat from the sun or from a controllednuclear reactionboils water, which then expands, moves aturbineand generates power. Why water? It is cheap; it absorbs a lot of "latent ...
由第一段中的“Thermoelectric generators (热力发电机) turn waste heat into electricity without producing greenhouse gas emissions, like a free lunch. (热力发电机将废热转化为电能而不会产生温室气体排放,就像免费午餐一样)”和最后一段中的“Those could be installed everywhere from automobile exhaust pipes...
The efficiency of a machine, whether it is a steam engine or an information processor, rests on the second law of thermodynamics, which is all about entropy: that is, the energy 'lost', usually in the form of heat, whenever one kind of energy is transformed into another. In their analy...
Car or factory exhaust pipes could be coated with the material, less than 1 millionth of an inch thick, to harvest energy otherwise lost as heat and generate electricity. The physicists take advantage of the laws of quantum physics, a realm not typically tapped into when engineering power-gener...
Euro-MPs turn up the heat on energy projects.Reports that the European Parliament has begun an investigation into allegations that the European Commission has mishandled money intended for research into renewable energy sources. Fund allocation to the Joule program; Comments on the commission's ...
aAccording to the SPS idea, turn light energy into electricity energy – and converted to microwave energy back to Earth – at the earth surface microwave radiation back into the DC – Finally through invert convert ways and so on conversion into industrial AC electrical power. 根据SPS想法,把光...
On renewable energy installations such as biogas-, landfill gas- and bio oil engines and even at all kinds of industrial plants lots of waste heat is dissipated into the atmosphere. On the other hand, there is a proven, commercially available technology to convert it (partially) into electricit...

It isn't too hard to imagine that if we add heat energy to a gas we raise the temperature by causing its molecules to move around more vigorously which in turn makes it want to expand,for each madly careening molecule is knocking its neighbors farthe
