An atomic battery, nuclear battery, radioisotope battery or radioisotope generator uses energy from the decay of a radioactive isotope to generate electricity. Like a nuclear reactor , it generates electricity from nuclear energy, but it differs by not using a chain reaction .
A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.
Wi-Charge claims to deliver power using focused beams of invisible infrared light. The system consists of a transmitter and a receiver. Transmitter connects to a standard power outlet and converts electricity into infrared laser beam. Receivers use a miniature photo-voltaic cell to convert transmitted light into electrical power. Receivers can ...
Atomic beam is special case of particle beam; it is the collimated flux (beam) of neutral atoms. The imaging systems using the slow atomic beams can use the Fresnel zone plate (Fresnel diffraction lens) of a Fresnel diffraction mirror as focusing element. The imaging system with atomic beam could provide the sub-micrometre resolution.
A simple betaphotovoltaic nuclear battery can be constructed from readily-available tritium vials (tritium-filled glass tubes coated with a radioluminescent phosphor) and solar cells. [5] [6] [7] One design featuring 14 22.5x3mm tritium vials produced 1.23 microwatts at a maximum powerpoint of 1.6 volts. [5]
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.
Betacel is considered to be the first commercially successful betavoltaic battery. [ 1 ] [ 2 ] [ 3 ] It was developed in the early 1970s by Larry C. Olsen at the American corporation McDonnell Douglas , using the radioisotope Promethium-147 as the beta-electron source coupled to silicon semiconductor cells.
The full funding for construction was appropriated by US Congress in 1986 and on February 13, 1987, the construction of the main component, the CEBAF accelerator began. The first beam was delivered to the experimental area on 1 July 1994. The design energy of 4 GeV for the beam was achieved during the year 1995.
