POPS Sloshing Inside Earth Changes Protective Magnetic Field The Earth's magnetic field extends about 36,000 miles (58,000 km) into space, generated from the spinning effect of the electrically-conductive core that acts something like a giant electromagnet. The field creates a tear-drop shaped bubble that has constantly shielded life on Earth against much of the high-energy radiation flowing from the sun. The last major change in the field took place some 780,000 years ago during a magnetic reversal, although such reversals seem to occur more often on average. A flip in the north and south poles typically involves a weakening in the magnetic field, followed by a period of rapid recovery and reorganization of opposite polarity. Some studies in recent years have suggested the next reversal might be imminent, but the jury is out on that question.

POPSEnergy at your feet Finally, unlike roof-top solar arrays, which some find unattractive, the solar collectors in roads and parking lots would be invisible.” In the lab, small slabs were exposed to halogen lamps, simulating sunlight. Larger slabs were set up outdoors and exposed to more realistic environmental conditions, including direct sunlight and wind. The tests showed that asphalt absorbs a considerable amount of heat and that the highest temperatures are found a few centimeters below the surface. This is where a heat exchanger would be located to extract the maximum amount of energy. Experimenting with various asphalt compositions, they found that the addition of highly conductive aggregates, like quartzite, can significantly increase heat absorption, as can the application of a special paint that reduces reflection.

POPSAug. 14, 1888: I Sing the Meter Electric Thomson invented a commutator watt-hour meter (that measured the energy consumed), also in 1888, and brought it to market the following year. It worked on both alternating- and direct-current systems, but fell by the wayside in the late 1890s when the induction watt-hour meter came into general use, where it remains to this day.

POPSGM says Chevy Volt is on track for 2010 I sure hope they can pull this off. The introduction of a rechargeable electric car has the potential to be a game changer for our economy and global dynamics. I would imagine that the response to this in the market would dwarf that received thus far by hybrids. We are talking about truly revolutionizing one of the most important industries in the world. And don't forget the ripple effect this will have by creating the need to make enormous investments in our national electricity grid.

POPSSnowy Mountains Hydro Electric Scheme 
If a man has the faith the size of a mustard seed, he can say to a mountain 'move', and it will move. Started in 1949, the scheme provided employment for returned soldiers, 'New Australians', who came to Australia after WW2 to start a new life, to provide electricity for the states of N.S.W. and Victoria, and to turn the 'Snowy' River from it's flow into the ocean, back inland to the irrigation area in central N.S.W. The Government tried to sell the scheme in 2005, but widespread protests, arguing it was not theirs to sell, from people including 100 Mayors from N.S.W., prominent politicians, and conservationists, prevented the sale. As a result of the drought-in Australia, droughts go hand in with bush fires, Lake Jindabyne reached an all time low of around 10%.in 2005. Today the level is around 60%. 'Old' Jindabyne is beneath Lake Jindabyne. They decided to move the town. when the dam was built. Parts of it can be seen when the dam is low or when fishing. Particularly the steeple.
