Scroll Down there's lots of good information here.
The earth is capable of storing heat energy, for years. Tests that were performed by the University of Minnesota, and my tests on the Geodome in Montana confirm this.
In 6 months, heat or the lack of it, in the earth conducts about 20 feet (6 meters.) Since the orbit of the Earth is such that it matches ½ a year in that time, it’s quite capable of storing heat for even more than a whole year. Remember that permafrost in the Yukon may go 1500 feet (457 meters) into the Earth, in spite of the Earth’s hot interior. (That's 150 years worth.) So it’s just what we need.
So, what if we used concentrated solar heat to make some hot earth, and another body of cold earth? If they were within a short distance, we’d need an insulated separator. But we’d have a large temperature difference between areas dealing with heat flow and storage over an annual basis.
In theory, we are already able to concentrate solar heat to almost the temperature of the Sun. Is that warm enough? In France they have a reflective parabolic group of mirrors that will melt a foot (30 cm) wide hole in a ¼-inch (6 mm) steel plate in 60 seconds. So the capabilities are there.
As shown, two bodies of earth are prepared. The one on the left is heated with a reflective solar concentrator. Because it does not have to be of optical quality (we’re not building a telescope,) We can use aluminum foil backed by Natural Fiber Reinforced Concrete. However, we do have to track the Sun, and there are several ways of doing that.
This is directed into the earth to heat it up.
On the right side, is a infrared radiator. It happens that outside of where the Sun is, in deep space, the temperature is about 250° F. Below zero. Also, in most deserts, where there is plenty of sunshine, there are also very cold nights. We can capture this temperature difference to create our two temperature storage volumes of earth.
Thus, we have created a valuable asset. For all year long it will collect heat on one side, and disperse heat on the other. The biggest thing we need for the production of electric energy is a temperature difference.
While we can use the high efficiency alternator I show, others would prefer a more conventional method, such as the Jet Turbine or Sterling Engine connected to an AC Motor, (Motor/Alternator.)
The net result is a solar powered electric generation system, that not only will not rundown at sundown, but will continue to operate even in cloudy weather and even in winter. The storage capacity is very large, and can be built for powering a whole city if we like.
In addition to concentrated solar radiation on one side, the other part uses one of the most efficient heat movers—heat pipes. These can carry the stored heat to the generation system, and away into the cooled earth all during the day, while at night the cool earthen “heat” storage volume is cooled off in preparation for the next day.
By controlling the back flow of water within the heat pipes, and water collection places, we can create both switchable and one way heat pipes. The switchable ones can be controlled by computer, and the one way ones simply stop transporting heat when the output is too warm.
See: Heat Pipe Operations
This will prevent the two “heat” storage areas from operating improperly when the timing is wrong.
The volumes should be laced with temperature sensors in strategic locations so we can monitor and control its activities.
One advantage is that it can do this quietly, and continuously, all year, in-fact for years to come.
Thanks for your interest.
