Portasol Solar Tracker continuously faces the sun
Although solar panels are becoming more and more efficient, one of the most glaring oversights in solar technology has been the inability for panels to autonomously move along with the sun and maximize the energy it could take in. The Portasol Tracker, however, is aiming to change all that, as a market-ready rendition is finally set after seven years of testing. The Hydrasolar panel utilizes hydraulic motors along with sophisticated "passive solar trackers to affect the thermal expansion and contraction of a contained liquid to make the device rotate." Essentially, the movement of the liquid causes the panel to spin to the west along with the sun as the day passes on, ensuring that the maximum amount of energy is garnered during those precious daylight hours. Currently, a small selection of models and mounting options are becoming available, and while hard pricing doesn't yet seem to be available, feel free to hit the links below for a smattering of pics and even a quick video overview.[Via MAKE]
PSP camera doesn't like sunlight, garlic
Long-time PSP Fanboy reader Joel used the PSP camera to take pictures from his trip to Paris. He seems pleased by the camera's performance, especially considering its budget price. Take a look for yourself in his Flickr photostream. A close-up look at the pictures reveals tons of artifacting and other visual glitches, meaning the camera won't replace a dedicated digital camera.One of the more crucial problems with the camera appears to be how it reacts to sunlight. "I wanted to take a picture of the Eiffel Tower with the sunset. And guess what happened: for one little second, the sun was SO bright my eyes hurt and I had to close them, and the camera went completely black. The sun killed the lens for some time. I watching and taking pictures, all black, until I turned off the PSP completely, and rebooted it, and it was working again. My hypothesis is that the Sun might kill the lenses for a little time if it's too bright."It doesn't come as too surprising that such a cheap camera won't handle the sun's powerful rays. Hopefully, if Sony ever decides to officially release the peripheral in the States, the camera will be able to handle a bit more.
Edinburgh scientists craft microscopic nanomachines
There's apparently a good bit of conflict at the University of Edinburgh, as we've got one esteemed fellow claiming that nanotech products are potentially dangerous, and now we've got a professor of chemistry insinuating that his nanomachines can change the world. Regardless of their personal differences, David Leigh has borrowed an idea from 1867 in crafting "a minuscule motor that could lead to the creation of microscopic nanomachines," and while he credits the "Maxwell's Demon" as its inspiration, he hopes these plans will actually lead to something substantial. The bantam motor is entirely solar-powered, and has been "devised to trap molecules as they move in a certain direction under their natural motion." Preliminary tests have shown a nanomachine moving a drop of water uphill by using molecular force, which gives researchers hope that this discovery will allow these diminutive machines to "do things that are much closer to what biological machines do." Of course, even Mr. Leigh admits that predicting just how this can or will effect society is difficult, but considering that he's aiming to to bring things that "could happen in a Harry Potter film" to fruition, we won't count him out just yet.
Italian village gets lit up thanks to gargantuos mirror
Considering nobody (well, mostly) likes to be alone in the dark for months on end, a group of Italians have devised a method to brighten everyone's day. Due to their position around numerous mountaintops that cut off direct sunlight and warmth during the winter months, the villagers were previously left to fend off darkness and cold without any external assistance, but thanks to a ridiculously large mirror (and some clever engineering), all that's changed. The sun-challenged hamlet nestled in the Ossola Valley now has a "towering 26- by 16-foot mirror installed on the flank of one bluff," and it utilizes a "computer to follow the sun's path and cast its rays back on Viganella." The project, seven years in the making, was reportedly difficult to construct and fund, but now that they've forked out the €100,000 ($131,260) and rediscovered the sun, we imagine the current population of 185 will likely be on the rise when envious folks from neighboring towns start to move in.
Nintendo: sunlight is no big deal
Do you remember our earlier story where a NYC Event attendee claimed that sunlight interfered with the console? Turns out, sunlight isn't that big of a deal. 1UP recently asked Nintendo about the issue and received the following statement from a company representative, who was not named:"Our testing thus far shows no great risk of light interference when playing a game that relies on the pointer and sensor bar."Still worried? Reassured by the comfortable embrace of mother Nintendo? [Thanks Erich!]
Sunlight: Wii's biggest foe [update 1]
Nintendo Wii's sensor bar goes awry when confronted with natural light, according to a report by a "Warpstar Knight" on the Nintendo NSIDER Forums. The impressions, from OMBRENOIR17's September 14 visit to the Nintendo World Store (soon to be posted on Nintendo Gal), reveal that Mother Nature's carcinogen forced Metroid Prime 3 kiosks under curtains and completely shut down Wii Sports Tennis and Shooting Game. The kiosks returned to normal as soon as the bright star took a few steps back.It is as of yet unclear how garlic affects Wiimote functionality or load times.[Via Engadget][Update 1: A representative for Nintendo told 1UP, "our testing thus far shows no great risk of light interference when playing a game that relies on the pointer and sensor bar."]
Sunlight messing with gameplay?
Over at the Nintendo NSider forums, a poster documented their time with the Wii during the NYC event. Yes, late coverage, but it poses an interesting scenario all the same. Turns out, the sunlight affected gameplay for this poster during the event, affected gameplay for the worse. To quote:"We know that the sensor bar goes all wonky when halogen lights are in the room. But did you know that natural sunlight messes it up too? That's right, if you have the sun beaming right onto the sensor bar, it doesn't work. For about an hour or so, the sun shone right into the store, the two MP3:C kiosks had to have curtains above them, and the Wii Sports Tennis and Shooting Game kiosks were unplayable since they were "shrouded" in sunlight. Later the sun went behind a building, and everything was in working order again."Interesting, however does it actually affect most of us? With the advent of curtains (or mini-blinds, if you're that kind of person), we're hard-pressed to believe this will really hurt the experience had on the console. That is, only if you're playing on the front porch or out by the pool.
Sunlight disables Wii sensor bar?
It's hard to think of that cute little Wii box harboring vampiric tendencies, but beyond its Nintendo-confirmed aversion to halogen lights, the Wii sensor bar apparently can't handle your garden variety sunlight either. This little "quirk" was discovered by OMBRENOIR17, an official Warpstar Knight over at the Nintendo NSider Forums, who experienced an hour of downtime at a recent Wii demonstration at Nintendo World when the Sun hit the showroom and shrouded the display units in light. According to trusty ol' Wikipedia, "sunlight" is apparently quite commonly encountered by the Earth's surface dwellers, and might even pose a problem to the console's casual target market, but we don't foresee it posing much of a threat to Engadget HQ bunkers. Threat averted.[Via digg]
