When you addPV solar panelsto a whole home solar generator, you can power your home without worrying about gas prices or utility companies. Harvesting the clean, renewable energy of the sun allows your solar generator to be recharged during a blackout and provides sufficient power to keep your...
This is one of the oldest designs for fuel cells; this type was the first the United States space program used to produce electricity and drinkable water on-board rockets and shuttles. NASA favored this method because the alkaline cell has high efficiency and a low operating temperature. However...
As a result, he says “there’s a lot of discussions about how clean the [captured] CO2should be in order to use carbon-manganese instead of stainless steel, for instance.” This time around, Brevik and CIMC settled on carbon-manganese steel, which limits the size of...

While not as popular or widely used as EVs,FCEVsare gaining traction around the world. Like EVs, they’re powered by electric motors however instead of plugging into an external power source to recharge the electric battery, FCEVs use a built-in fuel cell to generate power. This take...
They are also similar to batteries in that they generate electricity from a chemical reaction. But unlike a battery, you can continually recharge a fuel cell by adding chemical fuel -- in this case, hydrogen from an onboard storage tank and oxygen from the atmosphere. The basic idea is to...
Therefore you must either size your SLA to last all day or carry a charged set of spares since you will not be able to recharge them quickly enough pond side. SLAs also have a maximum discharge rate limit that is lower than a similarly sized NiMH battery. SLAs can be used for ...
The coolant used in most air conditioning systems is a refrigerant called Freon. If the system does not contain the proper amount of Freon, little or no cooling will take place. If you suspect a Freon problem, call a professional service person to recharge the system.Caution:Do not try to...
between 60 and 110 watts, whilemostflat panels are down in the 15 to 60 watt range. No contest! The energy savings you’ll get might even pay you to buy a flat panel to replace an old CRT. You can calculate this yourself. Here’s how. ...
