Some of that power can then be run back through the fuel cell to convert the stored water back to oxygen and hydrogen fuel through electrolysis. This system boasts very high efficiency, but is also massively complex and expensive to produce. The Invention of the Fuel Cell In 1839, Sir Willi...

The tool uses the same principles as a resistance soldering tool, but in a significantly less expensive package. We'll look at this in more detail next. Beads and Joints Hardened solder and the connection it makes are collectively called a joint. Stained-glass artists often refer to it as ...
Not all power plants rely on falling water. Many take advantage of steam, which acts like a fluid and can therefore transfer energy to a turbine and, ultimately, to a generator. The most popular way to make steam is to heat water by burning coal. It's also possible to use controlled ...
Electrical power travels from the power plant to your house through an amazing system called thepower distribution grid. The grid is quite public — if you live in a suburban or rural area, chances are it is right out in the open for all to see. It is so public, in fact, that you ...
A typical large wind turbine can generate up to 1.8 MW of electricity, or 5.2 million KWh annually, under ideal conditions -- enough to power nearly 600 households. Still, nuclear and coal power plants can produce electricity cheaper than wind turbines can. So why use wind energy? The two ...
but this greatly increases the cost of creating a solar farm in both real estate and natural resources. From a monetary standpoint, solar used to be one of the most expensive power sources to build in comparison with the energy collected.However, prices have trended downwardin recent years, ...
Electrical power is a little bit like the air you breathe: You don't really think about it until it is missing. Power is just "there," meeting your every need, constantly. It's only during a power failure, when you walk into a dark room and instinctively hit the useless light switch...
