Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
Every human activity, transport and industrial process generates waste heat, being possible to harvest residual energy from cars, aircraft, ships, industries and the human body. [1] From cars the main source of energy is the exhaust gas. [32] Harvesting that heat energy using a thermoelectric generator can increase the fuel efficiency of the car.
Hoyt Clarke Hottel (1903 – 18 August 1998) was a professor in the department of Chemical Engineering at the Massachusetts Institute of Technology (MIT). He was an expert on energy, radiant heat transfer, fire, fuels and combustion.
Decay heat is the heat released as a result of radioactive decay. This heat is produced as an effect of radiation on materials: the energy of the alpha, beta or gamma radiation is converted into the thermal movement of atoms. Decay heat occurs naturally from decay of long-lived radioisotopes that are primordially present from the Earth's formation.
Active atmospheric water collectors have been in use since the commercialisation of mechanical refrigeration. Essentially, all that is required is to cool a heat exchanger below the dew point, and water will be produced. Such water production may take place as a by-product, possibly unwanted, of dehumidification. [3]
The MIT Nuclear Research Reactor (MITR) serves the research purposes of the Massachusetts Institute of Technology. It is a tank-type 6 megawatt reactor [ 2 ] that is moderated and cooled by light water and uses heavy water as a reflector.

In winter, the process is reversed so that the roof pond is allowed to absorb solar radiation during the day and release it during the night into the space below. [39] [40] Indirect radiant cooling - A heat transfer fluid removes heat from the building structure through radiate heat transfer with the night sky. A common design for this strategy ...
