SOLAR HIBERNATION AND ANNUAL HEAT STORAGE

As we get more and more into Solar Hibernation, the winter temperatures will get colder each year until food cannot be grown outdoors. Even today farmers are in trouble making enough money to pay their bills. More farmers are taking their own lives in record numbers. Growing food in greenhouses is expensive to heat in the winter but as food becomes less available and in short supply, as predicted, the price of food will go up rapidly. The cost of heating a greenhouse can be held down by heating as small an area as possible and use annual heat storage to reduce the amount fuel needed.
First lets get into annual heat storage where I have a lot of knowledge. Over 3o years ago I did a lot of research on it because I wanted to take advantage of it when I was designing a house for my wife and me. We wanted to save the hot air in the attic in the warm and hot weather conditions. Our builder buried hundreds of feet of thin wall plastic pipe through which the hot air was blown and absorbed in the dirt around the pipes. It has worked extremely well paying for the cost of installing the system many times over. With what I know now I have worked out a far better way of doing it. The improved way will use a metal roof with flat extruded aluminum tubing that would be in contact with the metal roof to transfer the heat from the roof to the tubing filled with water. When the water reaches a certain temperature, water to be heated from an insulated storage tank is pumped up through the bottom of the aluminum tubing and the hot water is forced out through the top and down a pipe back to the hot water storage tank. This hot water is used to heat a house or areas of a greenhouse.
Second the areas to be heated must be as small as possible and well insulated. In a greenhouse it must keep the plants protected at night and allow the plants to get the sun's rays during the time they are available. Therefore the insulation must be movable. The hot water storage needs to be able to store a very great amount of heat and to do that, phase change materials have to be used. Phase change materials are like ice to store cold. Going from water to ice is a phase change and going from ice to water is also a phase change. Now we want to store heat so we want a material that melts at a higher temperature that is the same as the temperature we want the water saved. It has to be inexpensive enough to be practical and long lasting. More research has to be done to find an optimal material. This same type of system can be used to help heat any living space. The hot water can be pumped through fin coils as heaters or the heat from the tank to air around the tank inside the insulated area can be used to heat areas using an existing heating system.
I have run out of space so I will continue this in 2 weeks and at that time I should have the model of the generator building complete. Any help on this will be greatly appreciated and you could have a fun experience.
