We've had the iPhone 3G just three days, but we've manged to give it a good shakedown. Today, CNET Labs finished its first round of talk time testing for both the EDGE and 3G networks. On EDGE the iPhone 3G fell about an hour short of its rated time of 10 hours, while 3G calls matched the promised time of 5 hours. Those times aren't bad, but we'll run another round just to be sure. And in any case, actual day-to-day use will be the real test of the iPhone 3G's endurance. Ideally, it should … Read more
How 1.0 iPhones use battery life with the 2.0 firmware and all those tantalizing applications is something that may be worth considering against the iPhone 3G's voracious appetite for power. During the past weekend, as new applications get tested out, I've seen the iPhone 3G use more and more power with the charge indicator gradually slipping away, ultimately flashing the "low battery" warning. This warning wasn't something common with the 1.0 iPhone I had. In fact, I had never seen that "low battery" indicator even after 7 days of camping-like … Read more
There are several ways one can harness natural energy. In addition to the sun, wind, tides, and geothermal activities, the human body itself is increasingly being used to produce energy charge all sorts of electricity-hungry devices.
Music company Orange and GotWind, a firm specializing in renewable energy, have teamed up to create a device called the Dance Charge. Weighing 180 grams (about 6.3 ounces), you strap it around your arm. Dance Charge then uses the kinetic energy generated by your body in motion to juice up your phone.
It also uses a system of weights and magnets to produce … Read more
You've been driving a hybrid car (good for you, by the way!) and eating veggie burgers, and yet still don't feel environmentally conscious enough? Well, you are probably not alone. And now there's a way for your life style to get even greener: the Medis 24/7 fuel cell powered flashlight/charger.
The lengthy name says it all, this is a flashlight and a charger kit that's powered by one Medis fuel cell. The cell can provide enough power for the flashlight to be used, on a "real world" basis, for up to six … Read more
A123 Systems has signed on electricity utilities to use its lithium-ion batteries for short-term energy storage, according to a company executive.
The company, spun out of the Massachusetts Institute of Technology, is a closely watched venture that is best known for activity in the auto and power tools markets.
But lithium-ion batteries, already used in millions of consumer electronics devices, can be plugged into the electricity grid as well, according to … Read more
Presumed Republican presidential nominee John McCain on Monday proposed a $300 million prize to develop a car battery that will "leapfrog" today's plug-in hybrids.
In an energy policy speech at Fresno State University in California, McCain also called for an overhaul to existing policies that favor domestic ethanol production--one of the biggest differences he has with his expected opponent, Senator Barack Obama.
McCain said that, if elected, his administration would issue a Clean Car Challenge that would give give a $5,000 tax credit to people who purchase "zero-emissions cars."
There would be a sliding … Read more
This year many riders in the San Francisco AIDS Foundation and the LA Gay and Lesbian Center's annual 7-day AIDS LifeCycle bike ride from San Francisco to Los Angeles were toting iPhones - tucked away in their spandex or in their Bento boxes on their bikes.
The iPhone was the mose commonly spotted PDA, but man riders had Blackberry devices too. In any case, having a PDA was a great way to keep up with news and to send out updates about our trek's progress. Each day the Ride featured 2500+ riders cycling more than 70-100-plus mile routes. … Read more
SMK has a prototype TV remote that tosses out the batteries, relying on kinetic energy instead to work.
According to the literature, the channels, volume control and On/Off power switch are controlled by working a trigger on the handle. When pulled, an electromagnetic induction coil rotates at high speed by means of gears. This, in turn, generates a current of 20-30mA--sufficient to change the channel via infrared light. Two consecutive pulls will turn the TV on or off, while volume control is activated by pulling the trigger and pushing a button simultaneously.
Of course, don't expect any fancy … Read more
The public-art organization Creative Time unveiled an interactive exhibit called "Playing the Building"--a 9,000-square-foot, site-specific installation by renowned artist David Byrne (lead/founder of retro-pop group Talking Heads).
What once served as a soaring waiting room for passengers to board ferries bound for South Brooklyn until 1938, the Battery Maritime Building in lower Manhattan was transformed into a massive sound sculpture for which all visitors are invited to sit and "play." The project consists of a retro-fitted antique organ in which the innards are replaced with relays, wires, and light-blue air hoses, and placed … Read more
