Furnace Modification Printer Friendly Version
I have a hot water heating system. The furnace heats the water in the small expansion tank, which goes thru pipes along the baseboards to heat the rooms. This same system also supplies the hot water to showers and sinks. In the cold of winter, average burning about 6 gals of oil per day to take care of these needs, and with ever increasing cost of oil, this gets expensive. My idea is that like one of these small electric immersion things that can put in a cup of water to heat it up. Could something on a large scale, some type of heat probe be inserted into the expansion tank of the heating system. After the furnace has heated the water sufficently, this item, powered by electricity, could then keep the water at the needed temperature, without having to use the furnace again, therefore saving the cost of burning oil. Could this implement be thermostaticaly controled, so that as water cooled, it automaticaly came on to bring water back up to the temperature needed ?

Bunk Desks Printer Friendly Version
Being a teacher, I find that my classroom is too crowded with lab tables to maneuver (16 lab tables for 32 students). I think I should be able to make use of the vertical room space with bunk desks. We could seat belt the students in up top.

Natural Air Conditioner/Heater Printer Friendly Version
Since the ground temperature remains between 50-55 degrees F year round we could use nature to cool and heat our houses and businesses. Transfering the heat from the attic through the foundation walls in the basement into the ground in the summer time. Probably could use the fact that heat rises to create a ventilation system that is naturally powered too instead of using an electric fan. Then in the winter, using the difference in temperature between the frost layer and the 50 degree layer to transfer heat into the building using an intricate ventilation system.
