This is Rex. Not the man, he's called Hayden—Rex is short for Robotic Exoskeleton, and it's the name of the robotic pants Hayden's wearing. Robotic pants that let him walk for the first time in five years.

There are a couple of minor issues with Rex in its current form—it moves very, very slowly, with the robotic legs taking an age to trundle slowly forward, plus there's the awkward $150,000 price tag it'll have when it launches internationally in 2011. But apart from that... it's robot legs! Working robot legs! Here's a video of Hayden & Rex joined together at the hip, thigh, knee and calf.

Lunokhod 2 (Луноход, moon walker in Russian) was the second of two unmanned lunar rovers landed on the Moon by the Soviet Union as part of the Lunokhod program.

The Luna 21 spacecraft landed on the Moon and deployed the second Soviet lunar rover (Lunokhod 2). The primary objectives of the mission were to collect images of the lunar surface, examine ambient light levels to determine the feasibility of astronomical observations from the Moon, perform laser ranging experiments from Earth, observe solar X-rays, measure local magnetic fields, and study the soil mechanics of the lunar surface material.

USB Chicken Burger 4-Port Hub allows you to connect 4 different USB devices. It's another little fancy stuff on your desk.

Wind turbines? Dontcha hate them! Horrible things going round-and-round. Roundandroundandroundandround. They make a lot of noise, and bits seem to keep on falling off them. Dangerous.

Then there’s the NIMBY neighbours: “Oh, we don’t want one of those here,” they say. “Renewable energy: yes. Somewhere where it’s inconvenient: NO!” It’s as though they think a wind-energy solution can be integrated into every house with minimal visual impact.

"Will electric vehicles bring down the U.S. power grid? The answer, equally bluntly, is: No. They won't."

The answer, equally bluntly, is: No. They won't."

"An experimental solar-powered plane landed safely Thursday after completing its first 24-hour test flight, proving that the aircraft can collect enough energy from the sun during the day to stay aloft all night."

Galaxy Zoo: Hubble uses gorgeous imagery of hundreds of thousands of galaxies drawn from NASA's Hubble Space Telescope archive. To understand how these galaxies, and our own, formed we need your help to classify them according to their shapes — a task at which your brain is better than even the most advanced computer. If you're quick, you may even be the first person in history to see each of the galaxies you're asked to classify.
