There are a growing number of designs being floated to make electricity from the sea. But the Seadog Pump may get the prize for the simplest.
Wave- or tidal-power devices use underwater turbines or buoys to convert the motion of the ocean's water into electricity.
The Seadog Pump from Independent Natural Resources in Minnesota just focuses on pumping water.
A floating station uses wave motion to drive a piston that pumps water through an exhaust pipe. That water is collected and then passed through standard turbines to make electricity when needed, returning the water to its source.
The company … Read more
The cap is designed to analyze the brain's electroencephalogram (EEG) waves, determining whether you're too fatigued to drive safely. It is just one use for a device developed by researchers at various Taiwan universities and the University of California at San Diego, who hope to expand the technology for applications in myrid other facets of everyday life.
The first dual G4 PowerPC systems from Apple were all heat sinks and fans. In this tradition, a rarefied Intel Skulltrail-based powerhouse from Thirdwave uses two top-line quad-core QX9775 processors and a bevy of Nvidia GPUs--and plenty of fans.
The system (photo) in fact looks more like a stand-alone power supply box than a computer. Of course heat dissipation is paramount in enthusiast screamers.
The original Apple dual G4 systems (circa 2001) were a testimony to heat dissipation--and Rube Goldberg. So much heat that the system could quite literally raise the temperature in a small room. (Note: I can testify … Read more
MENLO PARK, Calif.--Back and forth, back and forth. That's the idea behind WaveRoller.
The company, based in Espoo, Finland, says it has devised a way to generate electricity from waves without buoys or other floating devices, the mainstay of other wave power companies.
Instead, the company wants to plant oscillating fiberglass/steel plates on the sea bed. Waves rolling in push over the plates, which rebound after the wave passes to only be knocked down by another wave. The back-and-forth motion of the plates drives a piston and creates hydraulic pressure. The pressure ultimately gets fed to a … Read more
Let's say you have a backyard rodent issue. A big one. So big that you can't watch Caddyshack anymore without getting a tic.
The "Mega-Sonic Scatter-Cat" device supposedly "repels dog, cats, squirrels and other nuisance animals without harming them," according to Pocket-lint, using sonic and ultrasonic waves instead of buckshot. But who are we kidding here? Rather than something like the passively situated "Solar Chaser," the real reason to get one of these is to pretend you're aiming Harry Callahan's .44-magnum at the dastardly four-legged vermin up to 65 feet … Read more
What's this, the new Bose headquarters in New York? No, not at all--but that's the first thing that came to my mind when I saw this picture of the wraps coming off the new Museum of Arts & Design, which is located at 2 Columbus Circle and scheduled to open in the next few months.
For those of who don't follow New York real estate and architecture, the area around Columbus Circle is home to some of the most valuable real estate in the city, including the Time Warner Center (where, ironically, there is a Bose store, … Read more
Hydro Green Energy, which wants to plumb America's waterways for electricity, has received $2.6 million in funding.
The company wants to create somewhat small, modular turbines and then set them down in arrays in waterways. Each turbine would be capable of harvesting 250 kilowatts of power. The size of the array would then depend on the size and power of the waterway.
It hopes to plant these arrays in Minnesota, Louisiana, Mississippi, and other states.
When asked how RFID worked, a group of novices responded to a recent academic survey with "witchcraft" and "magic."
In a talk Monday at USENIX Usability, Psyschology and Security Conference (UPSEC) 2008 in San Francisco, Andrew McDiarmid of the University of California, Berkeley, shed light on how ordinary people perceive RFID-enabled cards in their day to day life. He said while novices and intermediates were familiar with times when RFID-enabled smart cards such as work access cards or transit cards didn't work, they couldn't explain it. On the other hand, advanced users knew enough … Read more
Over the last few months, mobile operators have been falling over each other to profess their networks as "open," but a closer look at what they're really doing suggests they have a long way to go.
Traditionally, mobile phone operators have kept a tight grip on their networks. They have determined which phones could be used, what applications could be accessed, which features were enabled, and where subscribers could go on the Internet. But over the past year, Internet companies like Google and Skype have joined with consumer groups to lobby lawmakers and the Federal Communications Commission … Read more
