POPSSpray-on solar cells
continues: "I think these materials have a lot more potential than traditional silicon," Jiang said. "They could be sprayed on any surface that is exposed to sunlight — a uniform, a car, a house." Another type of solar cell scientists are trying to develop are dye-sensitized cells, which so far are slightly less efficient than silicon cells, which convert about 12 percent of the sunlight that hits them into electricity. Typical organic cells only manage about 3 percent, prompting some scientists to caution praise for their use. Jiang and her colleagues made 20 tiny cells — each the size of a lower case "o" in standard 12-point print — and joined them together in an array to power the microscopic detector. The detector needs a 15-volt power source to work, and so far Jiang's solar cell array can provide about half of that — up to 7.8 volts in the lab tests she and her colleagues did. The next step, Jiang said, is to increase the voltage and then combine the tiny solar array

POPSOne hundred tesla without self-destructing Why would anyone need a magnet that strong? Greg Boebinger, director of the Magnet Lab, says that this magnetic field strength is the only way to test the properties of newly discovered high-temperature superconductors like iron oxyarsenide, which may improve the performance of MRI machines and high-voltage power lines while lowering their cost. A 100‑T magnet would also let you conduct certain zero-gravity experiments without traveling into space and let you develop magnetic propulsion systems that could eventually replace those that burn rocket fuel.

POPSWhat if Electricity Was FREE??? The life story and work of Nikola Tesla. He invented AC electricity, Neon Lights, Radio transmission, The Electric motor, Wireless electricity transfer, Remote control, Hydraulics, Lasers, Space weapons, Robotics, and many, many more things. As Tesla claimed to have invented a way to harness free energy from the voltage difference in the ionosphere that causes lightning, he was seen as a threat to the world energy economy and most of his inventions were classified for national security by the US government. A lot of his discoveries in physics have not been released to the public, despite being invented nearly 100 years ago. In 2006 the first company publicly announced it could successfully power items by remote power without wires, (news.bbc.co.uk/1/hi/technology/6129460. stm) something Tesla had invented nearly a century ago.
