For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. Organic chemists have now produced a light driven rotary motor in which ...

New rotor locks from Roemheld USA are designed to simplify maintenance for wind power plants. The double-acting hydraulic cylinder locks the rotor blade up to 6.5 megawatts, from –30°C to +70°C. The ...

So I just bought this nice new switch off Ebay for cheap and it has 4 very loud fans in it. I'd like to replace them with lower noise (and lower flow, I'll take my chances) fans so I can hear myself ...

This is University of Groningen professor of organic chemistry Ben Feringa. The naphthalene rotor is attached to the motor by a single carbon-carbon bond, which allows it to rotate freely. But the ...
