Cellphones without chargers, anyone?

http://www.sciencedaily.com/releases...0527105454.htm

Found this on my Science Daily RSS feed. They are developing a porous
silicon diode that can collect nearly every free electron around it. Fed
with a safe beta isotope radiation source with a half life in the decades
or longer, it will produce power nearly indefinately.

Can you imagine a cellphone powered by such a battery that never needs
recharging as long as you own it? You'd carry your nuclear battery from
phone to phone to MP3 player to radio as you upgrade for decades.

Beta radiation is stopped by a sheet of paper. Read how easy it is to
shield this source with the battery's plastic case.

We've only just touched the tip of the technology berg.....even in 2005.

How will big oil stop the production of a car running safely on such a
power source? Would it destroy the world economy as we know it?

Yes, but it will only produce a tiny fraction of the power needed to
operate one of today's cell phones. If they could improve today's
cell phone technology to be that power efficient, you could just use
today's batteries anyway, because your cell phone would run for months
without needing to be recharged.

The main application of this technology is for stuff where it's very
hard to replace batteries as in some embedded applications. And it's
intended for ultra-low-power needs. Not that this type of technology
will never mature for more conventional needs, but one wonders how
much tritium fuel you would need to carry around in your cell phone
battery?

I have no doubt that the companies that make batteries are already
developing much better battery technologies. There may be even better
new technologies on the horizon than this for consumer products.

Almost 30 years ago there were watches with Tritium backlights. The display
was always illuminated. I thought at the time they should put a something
under the Tritium panels to convert the light to electricity and power the
watch without a battery.

Yeah, but you know that argument isn't going to stop extremist
activistst who will see the word "nuclear" and have a fit over it. I
can see the "No Nukes in Cell Phones" protests now. Owning a "nuke"
battery will probably carry the same stigma to it as wearing fur does,
for quite a while.

I've already got my sign made and duct taped to the stick. We'll be
picketing in front of the cellphone stores...(c;

Of course, the first question will be..."Does it come with a Playstation
and 6GB digital camera?"....
