Learn more about heat pumps, an exciting technology that lets you heat and cool your home sustainably instead of HVAC.

which work best with large-scale stationary power generators. Fuel cells of this kind operate at very high temperatures (between 700 and 1,000 degrees Celsius). This high temperature makes reliability a problem because parts of the fuel cell can break down after cycling on and off repeatedly. ...
In winter, heat pumps work exactly the same way. But this time they pick up heat from outside and move it into your home. Of course, it’s sometimes freezing outside when you want to use your heater. But the air doesn’t need to be warm— it just needs to be warmer than the re...
How Modern Fuel Pumps Work Near the tip of the gas pump nozzle is a small hole, and a small pipe leads back from the hole into the handle. Suction is applied to this pipe using a Venturi. When the tank is not full, air is being drawn through the hole by the vacuum, and the ai...
What different types of heat pumps are there? There are different types of heat pumps:air-sourceandground-source. Heat pumps can also be paired with fossil fuel gas furnaces; these systems are often referred to ashybrid heat pumps. How does an air-source heat pump work?
Heat pumps also work extremely efficiently, because they simply transfer heat rather than burn fuel to create it. This makes them a little greener than a gas-burning furnace. And they don't just heat and cool buildings. They work best in moderate climates, so if you don't experience ...
By contrast, hardly anyone knows anything about fuel-cell cars and there are virtually no filling stations supplying pressurized hydrogen. The "hydrogen economy" is a far-off dream. Photo: It could be a while before hydrogen filling pumps like this become commonplace. Photo by courtesy of NASA...
How Do Plunger Pumps Work? Plunger pumps have a reciprocatingplunger or pistonthat moves back and forth, forcing liquids through a set of valves. Some simple examples in our everyday lives might include a bicycle pump, spray bottle, or squirt gun. ...
How do free energy machines work? Energy: For some work to be done on an object, energy is required. Energy is of many different types throughout the universe. The most common forms of energy we use or feel in our daily life are Kinetic energy, Potential energy, Electrical energy, and ...
