Energy Tower: Power for 15 Earths?

Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming. Those are pretty big claims, but the researchers from the Technion - Israel Institute of Science seem confident that the "Energy Tower" could be a major solution to the world's problems. They've been working on the concept since 1983, and together have spent more than 150 man-years researching, designing, testing, and analyzing. As project founder Professor Dan Zaslavsky explains, the Energy Tower works on the basic principle of convection: hot air rises and cold air falls. The 3,000-foot tall tower, with a diameter of 1200 feet, would take advantage of the heavy falling weight of cold air. Any kind of water - from a sea or drainage ditch - would be added to the top of the tower. Via: Israel21c

Edgar Cayce’s cold curecan end the misery, and help build yourlong-term natural health! We all know the dismal warning signs: a sore throat; runny nose; sneezing and coughing; a feeling of heaviness and dragging; or maybe just feeling out of sorts and screwy the day before. It varies -- that’s why it’s good to know your personal “storm signals,” an important part of self-health. I started out cold-prone. I remember getting up at 3:00 am, when it was dark and miserable outside, and going to work absolutely exhausted. We’d tried to keep the Cayce diet for years, with its stress on the right acid-alkaline balance. Still, Cayce had said more than once that a person didn’t need to get a cold at all. Here’s what he said to do. Baking soda (sodium bicarbonate) – This was the backbone of the Cayce cold cure, because it is one of the basic elements of the body, and strongly alkaline.
