In this application, the solar tower incorporates a grain silo into the system.  The grain silos come pre-fabricated and can be shipped directly to the site and built in place.

Two towers with different functions are used in this system.  One tower is for photovoltaics and the other is for concentrated solar heat.   The two towers use a series of mirrors that rotate around the top to direct the sun’s rays onto the mirrored cone in the center of the towers. The towers will have a clear dome plastic covering to keep the particulates from attaching to the solar panels.

The first tower in the system has solar panels that line the tower walls at an angle to eliminate shadows cast from solar cells mounted above each one. The reflector in the middle is made up of two-inch squares that make up a coned mirror the height of the tower. This mirror is connected to a motor which spins the mirror to maximize the sun’s rays shining on the solar panels.

Both towers have a continuous coiled water heat exchanger system. The first tower has the water coil behind the solar panels to cool the solar panels in the tower. Cold water is pumped in at the bottom and coils around the tower where it exits the top. This heated water is then pumped into the second tower.

The second tower is a solar heat collector which also has the water coiled along the tower walls. These walls are insulated to keep the heat in. The layer below the cover has an array of Fresnel lenses also in a dome shape.  These lenses intensify the solar rays to heat the water in the tube along the wall. This steam heated water then enters the steam turbine which uses a planetary gearbox which turns a generator.

This system is to be used primarily in daylight hours, but can also be used in conjunction with existing natural gas heated steam turbine applications.
