MIT Gurus Dream Up Sensor Network for Preventing Forest Fires


Thanks, MIT. Why don't you just make the rest of the world feel a little more useless. Every week or so, we're forced to stare at yet another amazing invention coming from your doors; to be frank, it's just downright unfair. All childish angst aside, the latest idea to come from the institution is one that could certainly be put to good use: a self-sustaining sensor network that taps into trees for power in order to continuously monitor forests for threats of fire. Moreover, the concept could be applied in other scenarios as well -- to detect potential threats such as smuggled contraband along a nation's borders, perhaps. Testing of the wireless sensor network (developed by the appropriately named Voltree Power) is scheduled to begin next spring, and we're hearing that pot-sniffing turtles may even be brought in to create a completely natural self-policing environment.

Home of the Future to Be Grown from Living Trees

Scientists Grow Tree Homes
If you're anything like us, you've dreamed of living like Robinson Crusoe -- in the trees, using what nature provided to make the tools necessary for survival. Well, we may soon be able to fulfill part of that dream. According to scientists from Tel Aviv University and MIT, we could see homes grown from trees within a decade. The new technique is far from your traditional topiary: Scientists use a technique called airoponics, where plants are grown without soil, that allows them to grow trees according to templates. This would allow architects and scientists to create basic structures such as park benches and bus shelters from plants.

The tree homes are designed by a group called Plantware, which hopes the homes will help reduce pollution and reconnect people with the Earth. The homes would come equipped with a whole host of eco-friendly features (not the least of which is the ability to convert massive quantities of carbon dioxide to oxygen), like solar panels and wind turbines for generating power and special composting septic tanks that convert human waste into nutrients for the tree.

Scientist hope to have the first prototype built within ten years, but expect this technology to be prohibitively expensive at first, available only to the most well off environmentalists. [From: Daily Mail]

Christmas Tree Powered By Electric Eel

Electric Eel Powered Christmas Tree
Marketing geniuses at Japan's Aqua Toto Gifu Aquarium have caught the attention of both the marine-life lovers and the media with a holiday display that uses a unique source of clean renewable energy -- an electric eel, otherwise known to us geeks here at Switched as Electrophorus Electricus.

The aquarium placed its "E-Tree" next to tan electric eel in a tank. Inside the tank, copper wiring has been run, and every time the eel brushes against the conductive wire, the tree's ornaments light up, much to the pleasure of spectators.

Tanks filled with electric eels and lots of copper wire aren't going to allow any of us to drop off the grid anytime soon, but still, it's a neat trick, no?

According to Wikipedia, electric eels generate electricity using three organs -- the main organ, hunter's organ, and Sachs organ -- that take up four fifths of its body. These organs act in a manner similar to charged plates in a battery. The average electric eel can produce up to 500 volts and one ampere of current (500 watts). That's enough to hurt -- a lot.

Oh, and electric eels aren't eels. They're more closely related to catfish.

Decorate Your Desk With the USB Christmas Tree

Decorate your Desk with the USB Christmas Tree
Even though listening to the Backstreet Boys version of 'Christmas Time' every hour on the hour -- at least while we're out shopping -- makes us want to seal our eyes and ears with a caulking gun, we still like to get into the holiday spirit... we just want to do it on our own terms.

So, for those of us who want to spruce up our cubicles for the holidays and would rather skip those lame snow flake cut outs that are the province of elementary school teachers, we suggest a USB Christmas Tree from Vat 19.
Made of six inches of clear plastic, this 'tree' is lit up from within by LEDs that shift from blue to red to green. The six -foot USB cord ensures you wont the tree crowding your desktop mousing space. And, at only $9.95, the USB Christmas tree is much cheaper than a real tree.
