Google has its PowerMeter, Microsoft has its Hohm and Obama has his “smart meters.” Got it? Good. Around two years after UK taxpayers began footing the bill for in-home energy monitors, it seems as if America’s current administration is looking to follow suit. While visiting the now-open solar facility in Arcadia, Florida today, the Pres announced that $3.4 billion in cash that the US doesn’t actually have has just been set aside for a number of things, namely an intelligent power grid and a whole bundle of smart power meters. Aside from boring apparatuses like new digital transformers and grid sensors (both of which are designed to modernize the nation’s “dilapidated” electric network), 18 million smart meters and 1 million “other in-home devices” will be installed in select abodes. The idea here is to give individuals a better way to monitor their electricity usage, with the eventual goal set at 40 million installed meters over the next few years. Great idea, guys — or you know, you could just advise people to turn stuff off when they aren’t using it, or not use energy they can’t afford. Just sayin’.

Oh yeah, everyone loves the extended battery, but are we really kosher with the added bulge? A team of boffins at the University of Missouri certainly aren’t, as they’ve spent the last good while of their lives researching and developing a new nuclear battery that could be used to power devices much smaller than, well, most anything. The radioisotope cell, as it’s called, can reportedly “provide power density that is six orders of magnitude higher than chemical batteries,” and while some may question the safety of this potentially volatile device, the liquid semiconductor (used instead of a solid semiconductor) should help ease concerns. The current iteration of the device is about the size of a penny, and it’s intended to power a variety of MEMS systems. Now, if only these guys could find a way to make a standard AA last longer than a week in our Wiimote, we’d be pleased as punch.

Without a doubt, the military is home to some of the best gadgets. Fortunately for us, the non-lethal stuff often makes it into the hands of consumers after companies finish milking the government of its R&D budget. Case in point: this electricity-generating backup. Designed for the military, the kinetic energy pack is suspended on a rail that generates electricity as you walk. The power generated will charge a standard US Marine-issue lithium ion battery pack or can be directly routed to whatever device you want to charge. The obvious benefit would be limitless power in the field freeing troops from carrying extra batteries on long missions. A power meter on the shoulder strap lets you monitor performance while a three-stage resistance device lets you regulate the power output. A braking mechanism lets you lock down the pack when you want to keep the pack steady. Otherwise, it looks like it’ll generate about 8 watts of power while walking or 44 watts of power when running. Do want. See it in action after the break.

Carbon nanotubes are kind of like peanuts. They both seem pretty simple at first glance, but with a little work, you can make pretty much anything out of ’em. Take this case, for example, as MIT boffins have discovered that by forming the tube-shaped molecules of pure carbon into minuscule springs, they could be “capable of storing as much energy, pound for pound, as lithium-ion batteries.” The real kicker is exactly how they’d do it — “more durably and reliably.” Essentially, these newfangled cells could be left alone for years on end without losing their charge, and unlike conventional batteries, these wouldn’t suffer from performance degradation when exposed to temperature extremes. Of course, anything as pie-in-the-sky as this is probably at least a decade or so out from Walmart shelves, but considering that the group responsible has already filed a patent, we’d say they’re pretty confident in the possibilities.
