The Energy Matrix

Corn Solar Collectors The United States is looking at ethanol from corn as a
renewable source of energy. The ethanol gets its energy from corn and the corn
gets its energy from the sun.
Ice from Coal ( Alchemy?) No, this article is about thermodynamics not alchemy. Most people get their ice cubes from coal and water. That is they get the electric power that turns water to ice from coal powered electric power plants. At this point, I hope you anxious to know how
many pounds ice can be made from a pound of coal, because I am going to tell
you.
Storing Carbon Dioxide
There are two "T" in
Carnot
Heat Storage and Carbon Dioxide. Though much about carbon dioxide storage has yet to be determined, three things are certain, that is that these stores will be huge, dense, and have temperature. The quantity of carbon dioxide that will be stored will necessitate high compression, huge volumes, and useful temperature. The reason I say that the temperature will be useful is that there is such a large range of temperature that could be useful. A store of dense gas at twenty degrees Centigrade above room temperature would be used by a CO2/Air radiator for room heating. Stored CO2 at twenty degrees centigrade below room temperature might work well for direct cooling (blowing air over tubes with circulating dense cold CO2). Circulation of dense CO2 at or near room temperature would be great source of heat for the evaporator of a heat pump in heating mode. CO2 at the same temperature would a great source of cooling of a heat pump condenser when the heat pump was operating in cooling mode.. Above ground insulated tanks of CO2 could be used for peak heat of day heat storage for heating, or they could be used to store the cool of the night as a heat sink for cooling systems during the peak heat hours of the day.

District Cooling in Europe The city of Amsterdam has an operating district cooling system. Heat is dumped into a man made lake at depth of 30 meters. Water is taken into heat exchanger at 6 degrees centigrade and returned... continue reading center column
U.S Congress to Investigate High Cost of Gasoline. ( 5-22-07) They may not have to search very far. In Brazil the majority of cars run on Flex fuel or pure ethanol. In the United States less than a thousand gas stations sell flex fuel. They are mostly in the Midwest where ethanol is produced from corn. Brazil wants to export ethanol to us by ship. They could supply ethanol to east coast and Gulf ports. However, congress has placed a 54 cent per gallon tariff on ethanol imports. If populist congressmen really want to lambaste the oil companies, they should lambaste the oil companies for not placing more flex fuel pumps in east coast gas stations. Oh, but tariffs are cutting off the supply of ethanol to the east coast, so the pumps would not have much to pump.
