Hasta La Gadget!

Sure, it’s been just a few months since the National Security Agency asked for a $900 million supercomputing complex – you know, to help out with all that internet wiretapping. But concern about deficit spending will mean shuttering 800 other federal data centers in the US, or 40 percent of total government capacity. The closures are part of a larger push toward greater efficiency and consolidation, with an estimated savings of $3 billion a year; moving services to the cloud will mean more savings in licensing fees and infrastructure. Single-digit savings might sound like chump change when you realize the federal information technology budget runs around $80 billion a year, but hey, it’s a start, right?

The hot summer sun sparked blazing advances in solar energy this week as Inhabitat reported that a crop of incredible solar-powered Supertrees sprouted at Singapore’s Gardens by the Bay conservatory. We also saw designers float plans for a series of gorgeous sun collecting water lily islands, and speaking of flowers, we learned that scientists are breeding cold-resistant super bees that can withstand mites and disease. Scotland made waves as well when it unveiled the next-generation Oyster 800 wave energy plant, and Japan’s Prime Minister signaled a sea change as he called for a complete phase-out of nuclear power.

Several cities took steps away from car culture this week as a Spanish town offered residents lifetime tram passes in exchange for their cars, and JetBlue launched a set of dubious $4 flights to offset the closing of the 405 freeway in Los Angeles. We also took a look at the green technologies launched by NASA’s soon to be extinct space shuttle program and we saw the unveiling of the world’s first student-built hydrogen racecar.

In other news, we peered into the future of consumer tech as we counted down our six most desired green upgrades for the Phone 5 and we saw Jawbone launch an app-powered wristband that promotes healthy living. LED technology also lit up our lives as Philips rolled out a beautiful new breed of luminous wallpaper and Chanel kicked of its latest fashion show with a line of LED-studded shoes. Last but not least, we spotted a set of magnetic building blocks that help Honduran families, and this week gadget expert and Engadget founder Peter Rojas closed our Ask a Tech Geek column with a look at six great ways to charge your gadgets with renewable energy. If you’re thirsting for more, don’t miss Peter’s posts about fine tuning your laptop to save energy, vanquishing vampire energy drain, and recycling your old cables and chargers!

When they’re not busy carving handsets out of teak (or rockin’ out with their pupils), the folks over at NTT DoCoMo apparently focus their efforts on saving the environment. Next year, the Japanese provider will begin outfitting its expansive cellphone tower network with ten “green transmission stations,” to be powered by an artillery of biofuels, wind and solar energy. This kind of infrastructure would obviously bring a smile to the face of ol’ Mama Nature, but it could also help mitigate the adverse effects of power outages and elfin insurgents. And for that, we should all be grateful.

Looks like harvesting waste heat is all the rage in 2011. Yet another team of researchers — this time at the University of Minnesota — has found a way to harness energy from our hot castoffs. The group has apparently created a brand spanking new alloy that spontaneously creates energy when its temperature is raised by a small amount. Future uses for the material, known as Ni₄₅Co₅Mn₄₀Sn₁₀, include charging a hybrid car’s battery with the help of waste heat from its exhaust. So what’s the trick? Well, this wonder material is a phase changer, meaning it can go from non-magnetic to magnetic in moments, when the temperature rises. When that happens, the alloy absorbs heat, and bam! You’ve got electricity. The team is also collaborating with chemical engineers to create a thin film version of the material that could be used to convert waste heat from computers. If phase changing gets you all hot and bothered, check out a video demonstration of the alloy’s sudden magnetism after the break.

650 feet! That’s as tall as 113 average-height American men stacked on top of each other. That’s the size of a 54-story building. In other words, that’s huge. But why? More »
