Black hole bomb

A black hole bomb is the name given to a physical effect utilizing how a bosonic field impinging on a rotating black hole can be amplified through superradiant scattering. An additional condition which must be met is that the field must have a rest mass different from zero. The scattered wave will then be reflected back and forth between the mass term and the black hole becoming amplified on each reflection. The growth of the field is asserted to be exponential and unstable. The mechanism by which the black hole bomb functions is called superradiant instability.

                                               

Harvesting lightning energy

Since the late 1980s, there have been several attempts to investigate the possibility of harvesting lightning energy. A single bolt of lightning carries a relatively large amount of energy. However, this energy is concentrated in a small location and is passed during an extremely short period of time ; therefore, extremely high electrical power is involved. 5 gigajoules over 10 microseconds is equal to 500 terawatts. Because lightning bolts vary in voltage and current, a more average calculation would be 10 gigawatts. It has been proposed that the energy contained in lightning be used to g ...

                                               

Hazardous energy

Hazardous energy in occupational safety and health is any source of energy that "can be hazardous to workers", such as from discharge of stored energy. Failure to control the unexpected release of energy can lead to machine-related injuries or fatalities. The risk from these sources of energy can be controlled in a number of ways, including access control procedures such as lockout-tagout.

                                               

Sun scoop

A Sun scoop or sunscoop is a refueling technique for starships seen in science fiction. It involves a literal scooping of plasma directly from the outer surface of a star to use as fuel. Doing so would be extremely dangerous and only used in emergency situations.

                                               

World energy resources

World energy resources are the estimated maximum capacity for energy production given all available resources on Earth. They can be divided by type into fossil fuel, nuclear fuel and renewable resources.
