Heating and Cooling - A Futuristic Approach

I remember a friend telling the directors at a nuclear plant that they need to invest a large amount of money to apply safety measures that would meet the needs of the future. They, however, couldn't think long term, so he left.

Well, I would suggest a heating-cooling approach that would provide temperature control world-wide, but it would take a long-term investment to achieve. Probably as I conceive of it it is impractical. But surely there are engineers who could improve upon the basic idea.

A radiator of water in an automobile circulates cool water to keep an engine's temperature down to prevent engine trouble. A high surface area of heat-conductive metal and the strong air-flow across its surfaces cools the heated liquid.

Now to my idea. We heat houses in winter, cool them in summer. What if there was a huge underground reservoir, or an individual underground reservoir, operating on the principle of a thermos bottle, that stored liquid heated by the air-conditioning output to be brought back up to warm the house in the winter.

"Waste heat" would no longer be wasted, and heating costs would be lower in winter. You'd get payback on your investment that would exceed that investment in dollar amounts.

I think this approach is used in Sweden. They have outside underground pools of water that are fully insulated. The water is heated in the summer by solar means and that heat is used in the winter to keep the temperature up in the house. Using "waste heat" from air conditioning would be good.

That is a brilliant hypothesis. Have you read this book?
