It's Lithium ion not Nuclear Power hehe

I think he imagines that having more energy to spare you will use the device more often and more intensivelly, and consequently use the functionalities that emit EM radiation more.


I guess tinfoil helmets can't be trusted anymore.

Well, for example running torrent servants 24/7 in the phone if battery would not be the problem, or record everything microphone hears, camera sees and GPS locates, save that data 24/7 to remote server and later decide what to keep and what not.

All around you there's EM radiation in the order of watts. There is enough to power a radio from the antenna alone if it's big enough. No effects have been observed this far, aferage lifesoan continues to grow in spite of EM, chemical, biological, superbug and whatnot pollution.

While high EM has been noted as a possible cancer factor, we're talking people living under power lines, which took in equivalents of hundred of watts hour. The phone doesn't exceed 4 W under the worst conditions and not for 24 hours for decades.

Even so, the emissions of you phone is a drop in the bucket, considering that in that area you have several APs, GSM, (several networks), a few tens of radio stations, a few TV stations, walkie-talkies from taxis, satellite coverage, power line hum, EM from electronics and PCs, lighting, space humming, and all kinds of other stuff all over the spectrum.

Not to mention hight energy stuff from the sun and ionizing stuff from space.

Don't let EM spoil your N900.

haha

then one should be really careful when walking around within wlan networks and microwave ovens. (and if you come to finland, you should really have your radon measurement device around 24/7)

it would require so much time to filter what is good to keep and what not that it will be completely useless....

Anyone working on solar panel rechargeable batteries? Like the handheld calculators have? Solar panels are everywhere nowadays, so why not on our mobilephones since we double it as a GPS on our dashboards.

There is a phone with solar panels on the back (I forget which one). The review I read said that they were pretty much useless though (too low power), and that leaving your phone in full sunlight for long periods wasn't a good idea anyway.

You can already buy them (that is an external battery pack with a solar panel for recharging), have a look on ebay (and elsewhere), though beware, I bought one off ebay and it was complete rubbish (the battery was nowhere near what was claimed and it couldn't seem to hold a charge). The problem is that small solar panels don't really capture enough energy to be very useful, larger ones are more expensive and cumbersome to carry around.

With solar panels now finding a more common spot on residential roofs and other places never before, I'm sure the technology for simple mobilephone battery could be improved. If I'm not mistaken it was also mounted on the Mars rover.
