Clean tech has seen a boost as the U.S. pours government funding into renewable energy, and China looks set to reap much of the benefits. Latest example: a Chinese wind-turbine company has just become the exclusive supplier for one of the largest wind-farm developments in the U.S.

Despite the vehicles' armor, rocket-propelled grenades (RPGs) can still take out Humvees and MRAP vehicles with ease. But a company wants to change that equation with airbags that neutralize incoming RPGs and prevent them from exploding.

The media generally portrays hacker as criminals going after law-abiding computer users, but one Dutch hacker has turned his sights on more fertile prey: other less-skilled, or even aspirational hackers. Like a digital stickup boy, he has remotely kidnapped illegally (according to Apple) jailbroken iPhones in the Netherlands, holding them hostage for five Euros.

In April, a team from Glasgow School of Art will shoot lasers at the heads of George Washington, Abraham Lincoln, Teddy Roosevelt, and Thomas Jefferson. And they will do it all in the name of preservation.

The Scottish artists have perfected a system of laser scanning giant monuments, ensuring the digital preservation of even their finest nooks and crannies. They have already completely digitized Scottish landmarks like Rosslyn Church and Stirling Castle. The team is also working in conjunction with CyArk, a non-profit dedicated to laser scanning 500 UNESCO world heritage sites.

Anyone with a cool $4 million and change might consider doing what 43 other people have done, and sign up for an orbital space vacation in 2012 with Galactic Suite Space Resort. The Barcelona-based company plans to open the first space hotel if all goes according to plan.

Even as some of the world moves into a future of unimaginably complex technology, many communities still lack the basic electrical infrastructure needed to power even simply electric devices like light bulbs. Unwilling to wait for the wiring to catch up to the demand, Danish researcher Frederik Krebs has created an LED lamp embedded within a flexible, printable solar panel that could replace the kerosene lamps still used around the developing world.

Security agencies have long used the canine nose to sniff out contraband like explosives, drugs, human traffic and the like by picking up the scent of criminals’ illegal cargo. Now British scientists are developing two sensor systems that sniff out the criminals themselves by zeroing in on a specific pheromone emitted when humans are in stressful, fearful situations.

Satellites currently must dodge an ever-growing gauntlet of other satellites and clouds of space debris, and this year the Pentagon has quietly upgraded its surveillance accordingly. The U.S. military announced yesterday that it now tracks 800 maneuverable satellites, compared to less than 100 prior to a February collision between an active U.S. satellite and a retired Russian communications satellite.

According to Kwabena Boahen, a computer scientist at Stanford University, a robot with a processor as smart as the human brain would require at least 10 megawatts to operate. That's the amount of energy produced by a small hydroelectric plant. But a small group of computer scientists may have hit on a new neural supercomputer that could someday emulate the human brain's low energy requirements of just 20 watts--barely enough to run a dim light bulb.

What’s better than packaging an incapacitating, “less-lethal” electric shock device in a shotgun shell so it can be fired from a conventional firearm? If you answered a bigger, longer-range electric shock device that can be fired from a 40-millimeter grenade launcher, then you and the Pentagon share similar sensibilities.
