Inhabitat's Week in Green: self-driving cars, solar parasols and the ultimate DIY Iron Man suit
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. What seems more futuristic: flying cars or self-driving cars? They both sound a bit like science fiction, but they're both getting closer to becoming a reality. In the latest chapter of Google's efforts to develop a car that uses video cameras, radar sensors and lasers to navigate through traffic, the state of Nevada just granted Google the world's first license for a computer-controlled, driverless Toyota Prius. Meanwhile, this week we also checked in on the PAL-V (which stands for "Personal Air and Land Vehicle"), a two-seat hybrid car and gyroplane that runs on gas, biodiesel or bio-ethanol. In other transportation news, the Texas Central Railroad floated a plan to build a $10-billion bullet train that would run between Houston and Fort Worth, and Toyota officially unveiled its second-generation 2012 RAV4 EV, which features a Tesla powertrain. We also saw green technology cropping up in unexpected places this week, like the $1-billion ghost town that will be built on virgin desert land in Lea County, New Mexico to test emerging green technologies. Construction on the ghost town is set to begin in late June. Milwaukee native Bryan Cera invented Glove One, a 3D-printed glove that doubles as a cell phone. And in Tokyo, participants heaved 100,000 LED lights into the Sumida River as part of the 2012 Tokyo Hotaru Festival. Although it certainly looked cool, that's a lot of LED bulbs to literally dump in the river, and it raises some questions about e-waste. GE found a more practical use for LEDs, unveiling a new LED light bulb to replace the 100-watt incandescent.
Researchers say crab-based computing possible, lobsters throw up claws in disbelief
IBM's Holey Optochip? Yawn. Fujitsu's K supercomputer? Yesterday's news. Forget about boring old conventional computing stuff, the future of computer technology lies in crabs -- lots and lots of crabs. Researchers at Kobe University and the University of the West of England's Unconventional Computing Centre have discovered that properly herded crabs can signal the AND, OR and NOT arguments essential to computers, not to mention those crucial 1s and 0s. Forcing two swarms of crabs into one, for instance, represents the OR gate -- a trick the computational crustaceans pulled off fairly reliably. Not every operation was pincer perfect, however, as the crabs tended to stumble a bit through attempts at signaling the AND function. At least guiding a group of crabs isn't as tough as herding cats -- researchers used a shadow to imitate a predatory bird and direct the hapless creatures accordingly. Sure, it may not be the first biological computer, but it just might be the first fear-based computer.
Slime molds could hold key to new kinds of intelligence, help Statue of Liberty walk
See that yellow amoeboid slime mold? It's up to something. A team of Japanese scientists at Future University Hakodate led by professor Toshiyuki Nakagaki has found evidence that physarum polycephalum -- or grape-cluster slime -- are capable of navigating mazes and can organize their cells to find the most direct route. Nakagaki and others believe this could be the key to designing bio-computers capable of solving complex problems. According to Nakagaki, the slime's cells appear to have a kind of information-processing ability that allows them to "optimize" the route along which the mold grows to reach food while avoiding stresses -- like light -- that may damage them. Over at Kyushu University, researcher Atsushi Tero told the AFP news agency: "Computers are not so good at analysing the best routes that connect many base points because the volume of calculations becomes too large for them. But slime molds, without calculating all the possible options, can flow over areas in an impromptu manner and gradually find the best routes." Tero and other researchers have expressed hope that slime mold networks could be used in future designs of new transportation systems, electric transmission lines and understanding the human nervous system. Just remember, if you're going to coat the interior of the Statue of Liberty with some pink slime you found in the sewer, make sure you play some upbeat music to go along with it. It's just a good idea in the long run.
