The technology relates to a system which harvests thermal energy from various sources (e.g., sunlight, cars, power plants, factories and other industries) and converts it into electricity. In this system, heat energy is harvested and then stored in a storage tank, using water as energy storage

The technology relates to an upright tubular fixed-bed reactor body comprising of a heat-dissipating pipe, which extends from the reactor tube wall, to ensure that heat is effectively transferred in highly exothermic reactors such as Fischer-Tropsch, which are prone to heat build-up. The heat pipe
