Green Goose sensors monitor your life, you earn experience points (update)

We're pretty certain that once embedded wireless sensors catch on, they'll pervade every aspect of our lives, and Green Goose is building a microcosm of that eventuality in the form of a role-playing game. The five-person SF Bay Area startup has embedded custom 915MHz radios and MEMS accelerometers in a variety of tiny transmitters which you can mount to household objects -- like a water bottle, bicycle, or the toothbrush above -- which report back to the receiver with your actions and thereby increase your score. Brush your teeth on time, take your vitamins, or exercise repeatedly within a couple hundred feet of the receiver, and you'll eventually level up. (Or, optionally, muck with the sensor just right, and it'll register points anyhow.) Presently, that level isn't worth anything, but founder Brian Krejcarek says there are tentative plans to tie these points into a real game and an API to build the idea out, and he's presently looking for partner companies here at the Launch Conference in San Francisco to help roll out the sensors (which cost approximately $4 each) under branded marketing initiatives of some sort. If you don't want to wait, the company will sell starter kits starting February 28th for $24. Not bad for a head start on the future, right?

Update: VentureBeat reports that Green Goose raised $100,000 in funding at the conference. Another interesting note: ReadWriteWeb reports that the sensors were originally pitched as a money-saving tool.

Update 2: $100,000, not $100 million. Whoops.

Apple patent application points to denser batteries, improved charging technique

Some might think a ten-hour Macbook battery mighty fine, but we're happy to say that Cupertino's not quite satisfied. AppleInsider spotted a pair of Apple patent applications detailing a improved way of juicing up those lithium-polymer cells, which should greatly increase the number of recharge cycles they can endure -- or, optionally, allow Apple to use denser batteries that last longer on a charge. We'll break it down for you: the graph in the upper-left shows how Li-ion batteries currently charge, first very rapidly (constant current, increasing voltage) and then more slowly (constant voltage, decreasing current) to top the cells off.

What Apple's proposing is the multi-step method depicted on the right, where current and voltage trade off, to charge the battery while being far less harsh on the physical chemistry of the electrodes inside. As you can see in the bottom graph, the multi-step CC-CV cells lose much less of their potential after 300 recharge cycles, but that's not all Apple's cooking up -- the company figures that it can increase the thickness of the electrodes to improve battery life (by as much as 28Wh/L, according to one chart) without negative effect thanks to the softer charge. Sure, we'd rather have plant-eating graphene supercapcitors, but this sounds like a plan for now.
