Flatsun: 60,000 LEDs Simulate the Sun

I didn’t think that anything could accurately emulate theSsun, but that didn’t stop Rafael Lozano-Hemmer from trying, as he used 60,000 LEDs to recreate some solar magic – albeit without the intense light and heat of the actual Sun.

At 4.5 feet in diameter, Flatsun is still a billion times smaller than the real Sun. Rafael used mathematical equations to position the LEDs in the large circular panel that mimics the sun’s never-ending movements. Custom panels inside the larger structure hold the red and yellow LEDs, which give off that eerie, but fascinating solar glow.

As people walk by Flatsun, it uses a video camera to responds to their movements. If the room is crowded, it’s turbulent, as if there were solar flares on Flatsun‘s surface. As the room empties, the installation slows down and finally shuts down completely.

An Earth-Sized Planet Has Been Discovered in Alpha Centauri, the Star System Closest to Us [Space]

Holy sci-fi awesome space balls. European astronomers have discovered an alien planet in Alpha Centauri, the star system that’s pretty much our neighbor. The planet, which is Earth-sized, is only 4.3 light years away. More »

Asteroid Dust Cloud Could Be Used to Fix Global Warming

A group of scientists from Scotland have an insane idea to help reverse the effects of global warming here on Earth. The scientists think they can grab a near-Earth asteroid called 1036 Ganymed and use it to him to create a massive dust cloud to block some of the Sun’s energy from warming the Earth. The scientists say that they only need to reduce 1.7% of the solar radiation that hits the Earth to offset a global temperature increase of 3.6°F.

The plan is rather far-out, and even the scientists admit that it’s no replacement for curbing greenhouse gas emissions here on Earth. The scientists envision using some sort of “mass driver” that can be used to push the asteroid to Lagrange point L1. Lagrange point L1 is where gravity from the Sun and the Earth cancel each other out.

Once there, the mass driver could then be used to blow a massive cloud of dust and debris off the asteroid to block sunlight. The dust cloud would need a mass of about 11 million-billion pounds and span about 1600 miles wide. I wonder if a slight miscalculation in the size of the dust cloud might block more sun than they intend and plunge the Earth into an Ice Age.

What Is the Hottest Temperature Anything Can Be? [Video]

Everybody knows about absolute zero, but what about the other end of the spectrum, absolute infinity, as it begs to be called? As you might be able to guess, there’s a lot more room to go hotter than there is to go colder, but there still has to be some sort of limit, right? More »

Solar Sunflower Charger Offers Flower Power

Looking for a solar charger for your gadgets, but want something other than a black box with a solar panel glued to it? Then Check out XD Design’s latest creation – the Solar Sunflower, a gadget charger perfect for those with or without a green thumb.

Designed to look like a small, potted sunflower, you can place it in a window or bring it with you outside to charge up your mobile devices. It’s got a powerful 2500 mAh rechargeable battery built in, so it’ll hold onto some juice even when the sun goes down. It’s got a USB connector for charging your smartphones and other small gadgets (sorry, no tablets), and a mini-USB input, which I can only assume is for charging its internal battery up without sunlight.

The Solar Sunflower is available from Design3000 for €59.50 (~$77 USD), and for wholesale purchasers over on XD Design’s website now.

Alt-week 9.8.12: Moon farming, self powered health monitors and bringing a 50,000 year-old girl to life

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

Altweek 9812 Moon farming, self powered health monitors and bringing a 50,000 yearold girl to life

Some weeks things get a little science heavy, sometimes it’s a little on their weird side, and there’s usually a bit of space travel involved, but these week’s trend seems to be “mind-blowing.” Want to grow carrots on the Moon? We got you covered. How about bringing a 50,000 year-old ancient human back to life? Sure, no biggie. Oh but what about a solar eruption that reaches some half a million miles in height. We’ve got the video. No, really we have. Mind blown? This is alt-week.
