A new, extremely black material can turn water into steam using only sunlight, without the need to bring the water to a boil. Made of gold nanoparticles tens of billionths of a meter wide affixed to a ...

Water and steam are the lifeblood of any steam-driven power facility, and proper chemistry control is critically important to plant operation, reliability, the bottom line, and especially personnel ...

A century-plus of steam-generated power production has shown the importance of water and steam chemistry. Just one boiler tube failure in a conventional unit or heat recovery steam generator (HRSG) ...

(Phys.org)—Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam. The new "solar steam" method from Rice's ...

Created by postdoctoral student Shaobo Han at Sweden's Linköping University, the substance takes the form of an inexpensive and highly-porous aerogel composed mainly of cellulose (and air), to which ...

Sometimes the objective of boiling water isn’t to get hot water. You might boil it to create steam, say, to turn a turbine and create power. A lot of heat might get wasted doing that boiling. But a ...

Steam turbines convert the thermal energy in motive steam to rotating mechanical energy, and the generator converts that energy into electrical power. One important requirement for safe and reliable ...
