An Australian company says it can produce enough electricity for 100,000 homes by using the movement of hot air. Hot air will drive turbines to create electricity, then flow out through a tall chimney The tower will be the second tallest structure in the world EnviroMission, an Australian company, wants to build it in the Arizona desert (CNN) -- You don't have to be a science major to know that heat rises: Just step into an attic on a hot summer day. But what you might not know is that this basic scientific reality could also help create clean energy for entire cities.
Can hot air be the free fuel of the future?
NOTE: Some major wind projects like the proposed TWE Carbon Valley project in Wyoming are already pricing in significantly lower than coal power -- $80 per MWh for wind versus $90 per MWh for coal -- and that is without government subsidies using today's wind turbine technology. The International Clean Energy Analysis (ICEA) gateway estimates that the U.S. possesses 2.2 million km2 of high wind potential (Class 3-7 winds) — about 850,000 square miles of land that could yield high levels of wind energy. This makes the U.S. something of a Saudi Arabia for wind energy, ranked third in the world for total wind energy potential.

BAE invisibility cloak hides vehicles as scenery, cars and cows
British defence company BAE Systems has developed an "invisibility cloak" that can effectively hide vehicles from view in the infra-red spectrum. The patented system -- called Adaptiv -- uses a matrix of hexagonal "pixels" that can change their temperature very rapidly. On-board cameras sweep the area to pick up the background scenery and display that infra-red signature on the vehicle. This allows even moving tanks to be effectively invisible in the infra-red spectrum, or mimic other objects. "The tank skin essentially becomes a big infra red TV," BAE Head of External Communications Mike Sweeney told Wired.co.uk. "You can display anything you want on it -- including a cow -- while the rest of the vehicle blends into the background."

Perhaps the most notorious suppressed invention is the General Motors EV1, subject of the 2006 documentary, Who Killed the Electric Car? The EV1 was the world's first mass-produced electric car, with 800 of them up for lease from GM in the late '90s. GM ended the EV1 line in 1999, stating that consumers weren't happy with the limited driving range of the car's batteries, making it unprofitable to continue production. Many skeptics, however, believe GM killed the EV1 under pressure from oil companies, who stand to lose the most if high-efficiency vehicles conquer the market.

"I would call it brain reading and we hope that in two or three years it will be available for use for paralysed patients." The experimental breakthrough came when the team attached two button sized grids of 16 tiny electrodes to the speech centres of the brain of an epileptic patient. The sensors were attached to the surface of the brain The patient had had part of his skull removed for another operation to treat his condition. Using the electrodes, the scientists recorded brain signals in a computer as the patient repeatedly read each of 10 words that might be useful to a paralysed person: yes, no, hot, cold, hungry, thirsty, hello, goodbye, more and less.
'Mind-reading machine' can convert thoughts into speech
Foxconn, which manufactures Apple's iPads, iPhones, iPods and Mac computers, has been plagued by a series of suicides at its Chinese plants. Its critics have argued that its factories, some of which are home to as many as 250,000 workers, are "electronic sweat shops" and that staff can quickly become depressed and alienated. Foxconn's chairman, Terry Gou, told staff that the company would start using robots for repetitive tasks on the assembly line. Foxconn is already using 10,000 of its "Shenzhen No. 1" robots, which resemble a simple mechanical arm, to lift, coat and weld metals.

11 cheap gifts guaranteed to impress science geeks
Science comes up with a lot of awesome stuff, and you don't need a Ph.D, a secret lab, or government funding to get your hands on some of the coolest discoveries. We've got a list of 11 mostly affordable gifts that are guaranteed to blow your mind, whether or not you're a science geek. Click on any image to see it enlarged.Theta Wave Brain Synchronization
This is a replication of a Theta wave entrainment rhythm first created by scientists in the 1960s to lull patients into a deep, colorful, creative dream state. Listen to it for 10 minutes, longer if you can. The longer it plays, the deeper you’ll go. So go.
In a new study, researchers report that bumblebees were able to figure out the most efficient routes among several computer-controlled "flowers," quickly solving a complex problem that even stumps supercomputers. We already know bees are pretty good at facial recognition, and researchers have shown they can also be effective air-quality monitors. Bumblebees can solve the classic "traveling salesman" problem, which keeps supercomputers busy for days. They learn to fly the shortest possible route between flowers even if they find the flowers in a different order, according to a new British study. The traveling salesman problem is a problem in computer science; it involves finding the shortest possible route between cities, visiting each city only once. Bees are the first animals to figure this out, according to Queen Mary University of London researchers.

Futuristic, yet, but not the far-fetched science-fiction fantasy industrial design you might think – the Oculus by Schoepfer Yachts may not be for sale yet but it is already in pre-production mode with naval architects on board, so to speak. Hardly your typical houseboat , it is a virtual cruise ship for the rich and famous who can afford to buy it when it is fully planned and built. The anthropomorphism of this luxury floating home is of course intentional – the front deck like the gaping mouth of a gigantic sea creature and the sleek curves mimicking streamlined oceanic animals. Complete with a swimming pool on top and a futuristic interior design this is far more like a permanent mobile home than a cruising yacht. The smaller and simpler (both adjectives applied relative to its bigger brother of course) version of this spectacular design is the Infinitas, with a more sleek and streamlined profile and a semi-enclosed on-board swimming pool in the center but underneath the shell.It's about damn time, don't you think? Scientists at Lawrence Berkeley National Laboratory announced Wednesday that they have been able to confirm a new high-efficiency solar cell design that utilizes nearly the entire solar spectrum. Translation: They figured out a way to make solar panels generate electricity in the dark.
