Power Stealing (other)
Power stealing may refer to: *Energy harvesting * Electricity theft * Joule thief * Parasitic load (other) *Standby power Standby power, also called vampire power, vampire draw, phantom load, ghost load, or leaking electricity, refers to how certain electronic and electrical appliances consume electricity while they are not actively in use, but which are still ...

Energy Harvesting
Energy harvesting (EH) – also known as power harvesting, energy scavenging, or ambient power – is the process by which energy is derived from external sources (e.g., solar power, thermal energy, wind energy, Osmotic power, salinity gradients, and kinetic energy, also known as ambient energy), then stored for use by small, wireless autonomous devices, like those used in Wearable computer, wearable electronics, condition monitoring, and wireless sensor networks. Energy harvesters usually provide a very small amount of power for low-energy electronics. While the input fuel to some large-scale energy generation costs resources (oil, coal, etc.), the energy source for energy harvesters is present as ambient background. For example, temperature gradients exist from the operation of a combustion engine and in urban areas, there is a large amount of electromagnetic energy in the environment due to radio and television broadcasting. One of the first examples of ambient energy being us ...

Electricity Theft
Electricity theft is the criminal practice of stealing electrical power. The practice of stealing electricity is nearly as old as electricity distribution. Electricity theft is accomplished via a variety of means, from methods as rudimentary as directly hooking to a power line, to manipulation of computerized electrical meters. Electricity theft is most common in developing countries where power grids deliver inadequate and unreliable power. The global cost of electricity theft was estimated at $96 billion every year. Some punishments for the crime include fines and incarceration. The electricity losses caused by the theft are classified as non-technical losses. History On March 27, 1886 it was reported that electricity espionage was accomplished by unscrupulous persons tapping into Edison Electricity in New York. The Superintendent of the power station sent a power surge into the line to burn out or destroy foreign objects trespassing on the line. Types There are va ...

Joule Thief
A joule thief is a minimalist self-oscillating boost converter, voltage booster that is small, low-cost, and easy to build, typically used for driving small loads, such as driving an LED using a 1.5 volt battery. It can use nearly all of the energy in a single-cell battery (electricity), electric battery, even far below the voltage where other circuits consider the battery fully discharged (or "dead"); hence the name, which suggests the notion that the circuit is "stealing" energy or "joules" from the source – the term is a pun on "jewel thief". The circuit is a variant of the blocking oscillator that forms an unregulated voltage boost converter. History The joule thief is not a new concept. It adds an Light-emitting diode, LED to the output of a self-oscillating voltage booster, which was patented many decades ago. * US Patent 1949383, filed in 1930, "''Electronic device''", describes a vacuum tube based oscillator circuit to convert a low voltage into a high voltage. * U ...
