Floating nuclear plants could prove tsunami-proof

By - April 17, 2014 2 Pictures
The most frightening part of a tsunami hitting a nuclear power plant is what comes after – radioactive leaks that contaminate the water around the plant are exceedingly difficult to contain. The clean up of the radioactive water around the Fukushima Daiichi nuclear plant in Japan, which was struck by a tsunami in 2011, is expected to take decades. MIT researchers have come up with an alternative; they propose building floating nuclear plants, far enough offshore to simply ride out a tsunami and emerge unscathed. Read More

Seafloor carpet mimics muddy seabed to harness wave power

By - February 23, 2014 3 Pictures
Many organizations around the world are looking at ways to harness the power of waves as a renewable energy source, but none are covering quite the same ground as a team of engineers from the University of California (UC), Berkeley. The seafloor carpet, a system inspired by the wave absorbing abilities of a muddy seabed, has taken exploring the potential of wave power to some intriguing new depths. Read More

Organic flow battery could transform renewable energy storage

By - January 14, 2014 2 Pictures
Researchers at Harvard have developed an inexpensive, high capacity, organic battery that uses carbon-based materials as electrolytes rather than metals. The researchers say the technology stands to be a game-changer in renewable energy storage by solving the intermittent generation problems faced by renewable sources, such as wind and solar. The battery offers large volume electricity storage not possible with solid-state batteries and at a fraction of the cost of existing flow battery technology. Read More

World's smallest windmills to power cell phones

By - January 13, 2014 3 Pictures
Professor J.C. Chiao and his postdoc Dr. Smitha Rao of the University of Texas at Arlington have developed a MEMS-based nickel alloy windmill so small that 10 could be mounted on a single grain of rice. Aimed at very-small-scale energy harvesting applications, these windmills could recharge batteries for smartphones, and directly power ultra-low-power electronic devices. Read More

New tech could beam power from roadside stations to passing electric cars

By - November 14, 2013 1 Picture
Among the concepts put forth for decreasing the range anxiety associated with electric cars, one is to embed electrical coils within the asphalt. This would allow vehicles to wirelessly draw power from the road as they traveled, although it would also involve having to tear up existing roads to install those coils. An alternative could be on its way, however. Scientists at North Carolina State University are developing a system in which power could be transmitted from stationary roadside stations to mobile receiver coils in cars passing by. Read More

"USB condom" keeps your devices safe in public ports

By - September 16, 2013 2 Pictures
Conscious that injudiciously inserting one's USB charger into just any old public port might expose one's handheld device to any manner of nasty malware (or data theft, for that matter), experimental security outfit int3.cc has come up with the USBCondom, a go-between device that creates a break between the data pins of your USB connector and those of the public USB port you're plugging into. The power connection is maintained, however, allowing you to charge your smartphone or what-have-you in a state of graceful equanimity. Read More
