Are fuel cells environmentally friendly? Not always

Fuel cells are regarded as the technology of the future for both cars and household heating systems. As a result, they have a key role to play in the switch to renewable energies. But are fuel cells always more environmentally ...

The efficient choice among combustion engines

(Phys.org) —Researchers at ETH Zurich have developed an internal combustion engine that emits less than half the CO2 compared to a regular engine without compromising performance. This corresponds to fuel consumption of ...

GE introduces natural gas FlexEfficiency 60 turbine

(Phys.org)—General Electric has unveiled its new line of highly efficient natural gas burning turbines for use in generating electricity. The new turbines are able to rapidly increase or reduce their power output to meet ...

Normal air could halve fuel consumption

Every time a car brakes, energy is generated. At present this energy is not used, but new research shows that it is perfectly possible to save it for later use in the form of compressed air. It can then provide extra power ...

Electric shift prompts belt-tightening for German carmakers

German carmakers are increasingly turning to electric vehicles to master tough new emissions limits looming in the EU, but the shift away from internal combustion engines will entail years of lower margins and profits, cost ...
