Engineers from Princeton University have developed power-generating rubber films that could be used to harness natural body movements such as breathing or walking in order to power electronic devices such as pacemakers or mobile phones. The material, which is composed of ceramic nanoribbons embedded onto silicone rubber sheets, generates electricity when flexed and is highly efficient at converting mechanical energy into electrical energy. read more

Simple Windows Fixes

You may have already decided that the computer problem you’re dealing with is too hard to fix yourself, or at least not something you’re interested spending your time doing.

I’d argue that you should almost always try to fix your own computer problem, but I understand if you’re just completely against it. No hard feelings.

However, before you call tech support, or run off to the computer repair shop, I get one more shot to convince you to at least try something before you pay someone else for help.

Having worked in the computer service industry for years, I’m very familiar with the simple things that most people overlook, things that could completely eliminate the need to have a computer worked on at all.

You could quite literally save hundreds of dollars, and an equally valuable amount of frustration, by following some of the really easy things below.

Wipe Shred Delete Erase – What’s the Diff?

You can delete a file without erasing it, erase a drive without wiping it, shred a file without deleting it, and wipe hundreds of files at once… that were already deleted.

Confused? I’m not surprised! These four terms – wipe, shred, delete, and erase – might sometimes be used interchangeably but they shouldn’t be.

Each word implies something different being done to a file, folder, or even space that looks empty, on a hard drive, flash drive, or some other storage device. read more

New Jetpack Debuts

The dream of personal flight took a great leap forward last week as Jetpack Aviation unveiled its JB-9 jetpack in spectacular fashion. Lifting off from a boat, inventor and aviator David Mayman flew the powerful, agile JB-9 around the Statue of Liberty, pausing to salute and pirouette before touching back down. Running on kerosene and using two vectored jet engines, the JB-9 can reach high speeds and altitudes and offers a flight time over 10 minutes, depending on pilot weight. We spoke at length with Mayman to discover how the JB-9 works and how long it’ll be before we can buy one. read more

Ultrapower Laser Mimics Temperature of the Sun

Researchers have unveiled a radical new ‘ultrapower’ laser that can heat materials to temperatures hotter than the center of the Sun in only 20 quadrillionths of a second.

The technique, developed by theoretical physicists from Imperial College London, could heat certain materials to ten million degrees in much less than a million millionth of a second.

They say it could lead to a breakthrough in thermonuclear fusion energy, where scientists seek to replicate the Sun’s ability to produce clean energy.

Over the years, numerous tinkerers and companies have tried to transfer the fun of bicycling to the snow. While the fatbike has gained some recent traction, literally and figuratively, other designers still feel that replacing tires with skis is the only way to go. We’ve seen this trend in BikeBoards, the Skki and now the Snogo. The new ski bike uses an articulated steering system and front suspension to connect the rider to the powder or hard pack below. read more
