For example, the maximum physical possible energy extraction from a strait connecting two large basins is given to within 10% by:

Until recently, geothermal power systems have exploited only resources where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction.

The remote measurement, which provides the information for energy extraction, injects energy into the measured subsystem.

Every kind of energy extraction, of course, poses risks.

"Data's best theory is that these lines have something to do with zero-point energy extraction."

They also developed the latching control strategy to maximize energy extraction.

A larger area effectively increases the tip-speed ratio of a turbine at a given wind speed, thus increasing its energy extraction.

Are you going to broach the sensitive subject of new energy extraction in Arctic areas?

In the European Union we are dependent on fossil fuels, used for energy extraction.

In the Betz turbine the energy extraction manifests itself through thrust.
