Seeing where energy goes may bring scientists closer to realizing nuclear fusion

An international team of researchers has taken a step toward achieving controlled nuclear fusion — a process that powers the sun and other stars, and has the potential to supply the world with limitless, clean energy. The team developed a new technique to ‘see’ where energy is delivered during fast ignition experiments and improve energy delivery to the fuel target.

The Hydrobee: USB Power from Nature

Energy Inventions | Human Power | Hydro PowerWe just received an email from a company called Hydrobee, asking us to vote for them as Autodesk’s inventor of the Year. Having never heard of this we checked it out… what a neat invention! This soda-can sized device generates electricity for USB devices when you’re off the grid. It can generate power using flowing […]

Are we alone in the universe because all the aliens went extinct?

If we’re alone in the universe, then the big question is: Why? There are billions upon billions of Earth-like planets out there. Surely, life would have evolved many times over. But lo, Jody Foster couldn’t find any back in 1997, and today, almost 20 years later, we’re still searching. This conundrum is known as the Fermi Paradox, named after physicist Enrico Fermi, who famously asked “Where is everybody?” one day while eating lunch with his colleagues (note to self: nix the sad desk lunch; you’ll never get a paradox named after you this way), and scientists have been scratching their heads over it for decades. But in a new paper published this week in the journal Astrobiology, two researchers from the Australian…
