Known as PS10 and built by the Spanish company Abengoa Solar, the project produces electricity with 624
large moveable mirrors called heliostats, using these to concentrate the sun's heat to the top of a 115 - metre - high
tower where a solar receiver and a steam
turbine are located.
The «Living
Tower» design seen here is complete with solar panels, a rainwater purification system, and two
large wind
turbines on top for energy production.
«On the
largest turbines, researchers continue to use an undersized 75 - meter search radius, even though the much
larger turbines are known to catapult birds and bats much further from
turbine towers.
The technology, which EnviroMission calls a Solar
Tower power station, uses the sun's heat to warm a
large body of air which then rises through a vertical wind tunnel causing
large turbines to spin and generate electricity.

large wind
turbines, blades, and
towers.
It is possible that, if the eagle was hit by an ascending
turbine blade, it could have been thrown this far; however, research by Dr Cindy Hull in Tasmania has indicated that wedge - tailed eagles are most often hit by descending
turbine blades and that they rarely, if ever, fall as far as 180m from a
turbine tower (it is possible that the eagle could have been dragged by a
large scavenger).

The authors of the study estimate that all bird fatalities from wind
turbines range from 214,000 to 368,000 annually — a small fraction compared with the estimated 6.8 million fatalities from collisions with cell and radio
towers, 1.4 to 3.7 billion fatalities from cats, and of the many other, much
larger threats that birds face today.

Photovoltaic systems use conducting material to convert sunlight directly to electricity and need only nominal amounts of water to wash their solar panels, compared with the traditional steam -
turbine solar that uses much
larger volumes of water for cooling
towers.
Advancements undertaken by manufacturers include designing taller
towers and
