POPSJapan Plans Solar Station in Space The next step, expected around 2020, would be to launch and test a large flexible photovoltaic structure with 10 megawatt power capacity, to be followed by a 250 megawatt prototype. JAXA says the transmission technology would be safe but concedes it would have to convince the public, which may harbour images of laser beams shooting down from the sky, roasting birds or slicing up aircraft in mid-air.

POPS'Fear detector' being developed that will be able to sniff out terrorists Evidence that the smell of fear is real was uncovered by US scientists last year who studied the underarm secretions of 20 terrified novice skydivers. The researchers found that people appear to respond unconsciously to the sweat smell of a frightened person. Scientists at City University London now hope to develop security sensor systems that can detect the human fear pheromone. Team leader Professor Tong Tun told The Engineer magazine: 'The challenge lies in the characterisation and identification of the specific chemical that gives away the signature of human fear, especially the fear in relation to criminal acts.'

POPSAres I-X Launch: NASA's New Rocket Blasts Off On Test Flight The prototype moon rocket took off through a few clouds from a former shuttle launch pad at 11:30 a.m., 3 1/2 hours late because of bad weather. Launch controllers had to retest the rocket systems after more than 150 lightning strikes were reported around the pad overnight. Then they had to wait out interfering rain clouds, the same kind that thwarted Tuesday's try. The ballistic flight did not come close to reaching space and, as expected, lasted a mere two minutes. That's how long it took for the first-stage solid-fuel booster to burn out and separate from the mock upper stage 25 miles up. But it will take months to analyze all the data from the approximately 725 pressure, strain and acceleration sensors. Parachutes popped open and dropped the booster into the Atlantic, where recovery ships waited

POPSAlien Abduction Lamp Just what I always wanted... .:lol: Here's another prototype, not yet available: http://www.slipperybrick.com/2009/03/alien-abduction-lamp/ It must be a government conspiracy that it hasn’t been released yet. Gotta luv it. .:p

POPSWingsuit Flying This is really amazing. The art of flying the human body through the air using a special jumpsuit, called a wingsuit, that shapes the human body into an airfoil which can create lift.

POPSSalt and Paper Battery May One Day Replace Lithium Batteries more: The battery is made by coating the paper, made from this cellulose, with a conducting polymer and inserting a salt-solution-soaked filter paper between the paper electrodes. Chlorine ions travel from the batteries positive terminal to the negative terminal while current is produced in the external circuit by the flow of electrons. The battery can be recharged in tens of seconds because the ions flow through the thin electrode quickly. In comparison to a lithium battery that would take 20 minutes to recharge. The salt and paper battery is still in the early stages of development as compared to other thin-film technologies. For a battery to be cost effective you need to able to obtain the material at relatively low cost and have a good manufacture process in place. The battery could be produced commercially in about three years and made available to distributors. Via: RSC and Technology Review © 2009 PhysOrg.com
