In thermal power stations, mechanical power is produced by a heat engine that transforms thermal energy, often from combustion of a fuel, into rotational energy. Most thermal power stations produce steam, and these are sometimes called steam power stations. Not all thermal energy can be transformed into mechanical power, according to the second law of [...]
rectenna is a rectifying antenna, a special type of antenna that is used to directly convert microwave energy into DC electricity. Its elements are usually arranged in a multi element phased array with a mesh pattern reflector element to make it directional. A simple rectenna can be constructed from a Schottky diode placed between antenna [...]

In the majority of energy applications, energy is required in multiple forms. These energy forms typically include some combination of: heating, ventilation, and air conditioning, mechanical energy and electric power. Often, these additional forms of energy are produced by a heat engine, running on a source of high-temperature heat. A heat engine can never have [...]
Field Day stresses emergency preparedness. Frequently, entire radio clubs get involved and assemble a portable radio station in a field or park. Some might use quickly deployable portable antennas while other might erect more elaborate radio masts and towers supporting several antennas. Generators or solar power provide electricity to amateur radio transceivers, which may be [...]
