2. Thermoelectric generator - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_generator

   Thermoelectric generators function like heat engines, but are less bulky and have no moving parts. However, TEGs are typically more expensive and less efficient. [2] When the same principle is used in reverse to create a heat gradient from an electric current, it is called a thermoelectric (or Peltier) cooler.

3. Ceramic heater - Wikipedia

   en.wikipedia.org/wiki/Ceramic_heater

   A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [ 1 ] [ 2 ] [ failed verification ] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters .

4. Thermoelectric cooling - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_cooling

   Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.

   The first is through solar power, and it's the easiest way to charge when there's no power elsewhere. You can also top off the Grecell by plugging it into an AC outlet or into a car.

6. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   An electric heater is an electrical device that converts an electric current into heat. [1] The heating element inside every electric heater is an electrical resistor , and works on the principle of Joule heating : an electric current passing through a resistor will convert that electrical energy into heat energy.

7. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   Power outage: In case of a power outage, tankless heaters cannot supply hot water, unlike tank based heaters which can supply the hot water stored in the tank. LED Light Strobe effect: Most residential demand water heaters act by modulating the heating elements to match the flow rate. This is required to prevent overheating in the heating chamber.
