This is the company that projectile-spewed a bunch of fright-spew about their "Digital Angel", and had half the world in a tizzy about a device that could supposedly be tracked by GPS satellites. Nevermind the fact that GPS satellites couldn't even track a star gone supernova -- because they're beacons, not sensors -- but, people wanted to be frightened, and that outfit gave them all they needed to do an impressive (and collective) Mother of All Chicken Little impersonations.
Eventually the outfit toned down they hyper-claims, and fell from the limelight. If they're now touting that ten micro amp battery, I feel sorry for them. Please, someone come up with a list of useful devices that can get by without drawing more than ten microamps. I'll be surprised if even a digital wristwatch can run on that. But hey, maybe it can.
To put it in perspective -- watts = amps times volts. They say they're coming out with a three volt battery. (Wow, what kind of advanced technology does it take to slap two 1.5 volt cells in series?) So, how many watts will it put out? Three times ten millionths of an amp. Do the math.
How far would a signal powered by that infinitessimal power supply travel? Not much beyond the skin, if even that far.
There are plenty of things going on in the world to curl your hair and give you the creeps. This is not one of them.
