Faster Wireless to Compete with Speed of Fiber

Faster Wireless to Compete with Speed of Fiber

 Researchers at Battelle used off-the-shelf optical telecommunication
components to create a faster millimeter-wave device.

There’s no shortage of demand for faster wireless, but today’s fastest technologies–Wi-Fi, 3G cellular networks, and even the upcoming WiMax–max out at tens or hundreds of megabits per second. So far, no commercial wireless system can beat the raw speed of optical fiber, which can carry tens of gigabits per second.

How Our Eyes Adapt To Movement

How Our Eyes Adapt To Movement 

When an object moves fast, we follow it with our eyes: our brain correspondingly calculates the speed of the object and adapts our eye movement to it. This in itself is an enormous achievement, yet our brain can do even more than that. In the real world, a car will typically accelerate or brake faster than, say, a pedestrian. But the control of eye movement in fact responds more sensitively to changes in the speed of fast moving objects than slow moving objects.

Board A Train While It Is Moving

Board A Train While It Is Moving

When a train travels, one of the biggest problems is that the train has to stop and start again at each and every stop. This causes problems in two ways. First off, the journey is slowed right down as the train stops for several minutes and then has to wind back up to full speed only having to stop again shortly after. The second problem is the energy used to get a train moving.

Hypermiling Improves Gas Mileage

Hypermiling Improves Gas Mileage 

Bob Winger is that guy on the highway, puttering along in the far right lane.

As Chevrolet Tahoes, Cadillac Escalades and a host of other cars and trucks whip by in the passing lanes, Winger slowly accelerates up to the 60-mph speed limit on Interstate 64 in Newport News. He eases up on the gas a bit, fixated on a display next to his speedometer that shows his mileage.

Fake Bumps Used To Slow Down Drivers

 Fake Bumps Used To Slow Down Drivers

Some of the best bumps in in life are not obvious

Philadelphia is rolling out a program to try to get motorists to slow down.

The city is putting out high-tech plastic devices that create a 3-D image that looks like a bump in the road. Chief traffic engineer Charles Denny says in reality, the road is perfectly flat.

World Speed Record for Guitar Picking?

G4TV Recently aired on Attack of the Show – You Tube Star, and again on ABC Byte This in November 2007. This is NOT a music video, or musical in nature, he has other videos for music. This is ONLY a demonstration of alternate picking speed, and the technique used to obtain that speed. More videos after the jump.
