Conversely, if heat energy (collected from the sun, for example) ... The solution that exits the heat exchanger is now back up to 50 percent strength, and "charged" with heat energy.

Its combined-cycle setup allows it to reach 60% thermal efficiency, meaning that 60% of the heat energy input is converted to electricity, versus about 40% for a gas turbine alone. The heat recovery ...

Almost any homeowner could potentially benefit from a heat pump. Consider the case of Mike Ritter, who moved into a 100-year-old two-family home in Boston’s Dorchester neighborhood with his ...

The Quilt heat pump matches the efficiency of other Energy Star competitors and qualifies for government rebates. But unlike the others, it actually looks good too. Finally, a Heat Pump That Isn't ...

You can heat homes with gas, propane, oil or electricity. Or you can make use of the virtually endless supply of clean energy that lies right beneath your feet.

Recycling heat is actually quite simple. For example, ... The U.S. wastes more than half of the total energy we produce—mostly as heat, but also as gas, biomass, and methane.

The amount of heat needed to change one kilogram of ice (the latent heat) is then determined. Here is the equation that relates energy to specific latent heat. Key fact ...
