A tiny new wearable gadget called a thermoelectric generator (TEG) directly turns your body’s heat into electrical energy. TEGs use a difference in temperature—like your body’s temperature versus the surrounding air—to turn that energy into power. To establish equilibrium, heat automatically di...
Many people prefer to "sleep cold," and they don't mind turning down the thermostat into the low 60s or mid-50s at night. Some even like to turn off the heat entirely in the bedroom and sleep with a window open. Those who are comfortable dialing back this dramatically are able to red...
At best, these systems take one unit of fuel or electricity and turn it into exactly one unit of heat—that is, they're 100% efficient, like all electric radiators. Fuel-burning systems always waste some energy, so they're usually closer to 80% or 90% efficient, depending on the system...
heat and using it to reduce fuel demand for nearly 200 years. But a changing grid and advancing technology have ratcheted up interest in the field. “This is a hot area,” saysJeffrey Rissman, senior director of industry at Energy Innovation, an energy and climate policy and research firm....
If you want to turn off your heating system regardless of the temperature setting at the thermostat, and if the thermostat itself does not include an "off" switch (see the next description below) you can turn off the heat by switching off electrical power to the heating boiler or furnace....
a plant uses energy from the sun to grow, and energy is then stored in the newly grown parts of the plant. In a car, gasoline is burned so that the energy from the fuel can be changed into energy of movement (called kinetic energy) and heat. When you move your eyes to read this ...
Rondo Energyis one of the companies working to produce and deploy thermal batteries. The company’s heat storage system relies on a resistance heater, which transforms electricity into heat using the same method as a space heater or toaster—but on a larger scale, and reaching a much higher ...
