Thermoelectric energy harvesting mainly depends on the operation of the thermoelectric generator (TEG). A thermoelectric (TE) device can directly convert heat emanating from the Sun, radioisotopes, automobiles, industrial sectors, or even the human body to electricity. A TEG converts heat directly into electrical energy according to the Seebeck effect. …

Heat (i.e., thermal energy) is defined as the energy that is transferred spontaneously between two bodies due to difference in their temperature; heat flows from high to low temperature. There are three main well-known mechanisms for heat transfer: conduction through solid and fluids, convection through fluid, and radiation through solid, …

Sometimes long runways required by conventional aircrafts aren’t available to use or there is a need for an aircraft to use no runways at all. Vertical take-off and landing VTOL technology means aircraft can theoretically take off and land almost anywhere, making them far more flexible. They’re also able to perform …
