Jun. 16th, 2009 11:43 pmAfter, we visited twilite zone comics and then games and stuff - got micro mutants. Wargame with a tiddlywinks mechanic. looks fun!
Lunch/ Dinner at Gina's Cantina - then off to Sam's club - It turns out that my card from work got understandably canceled - semi annoying since it took a year to get the thing, but it was deactivated withing a week of departing. trouble of a yearly schedule, I suppose.
Tomorrow I do a callback for Georgetown gig? Wish me luck, dear journal!
Nokia developing phone that recharges itself without mains electricity
A new prototype charging system from the company is able to power itself on nothing more than ambient radio waves - the weak TV, radio and mobile phone signals that permanently surround us. The power harvested is small but it is almost enough to power a mobile in standby mode indefinitely without ever needing to plug it into the mains, according to Markku Rouvala, one of the researchers who developed the device at the Nokia Research Centre in Cambridge, UK.The difference with Nokia's prototype is that instead of harvesting tiny amounts of power (a few microwatts) from dedicated transmitters, Nokia claims it is able to scavenge relatively large amounts of power -- around a thousand times as much -- from signals coming from miles away. Individually the energy available in each of these signals is miniscule. But by harvesting radio waves across a wide range of frequencies it all adds up, said Rouvala.
The trick here is to ensure that these circuits use less power than is being received, said Rouvala. So far they have been able to harvest up to 5 milliwatts. Their short-term goal is to get in excess of 20 milliwatts, enough power to keep a phone in standby mode indefinitely without having to recharge it. But this would not be enough to actually use the phone to make or receive a call, he says. So ultimately the hope is to be able to get as much as 50 milliwatts which would be sufficient to slowly recharge the battery.
