Nuclear power source (maybe soon) commercially available ...
« on: October 02, 2007, 07:05:57 PM »
Hi,

according to this news http://www.pressetext.at/pte.mc?pte=071002033 article, finally the (almost) everlasting power source has been realized. They state the power source would last ~30 years and is based on the radioactive decay of tritium. During the decay beta particles are emitted, and now they found a way to convert them into electrical power.

So if this is not a fake, then a 'overunity' myth has been proven and realized by the scientists.  :o

U.S. Air Force:
"everlasting power source has been realized."

IcyBlue:
"So if this is not a fake"

You don't sound very credible in your fake prejudgement.

Are you for real?

I have  found this so far,
sounds very promising !
If somebody can find out more,
please post it here.
Hopefully this technology can be open sourced,
but I guess the military will have its thumb on it...?!

Here it goes:

Scientists Invent 30 Year Continuous Power Laptop Battery

Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.

Although betavoltaic batteries sound Nuclear they?re not, they?re neither use fission/fusion or chemical processes to produce energy and so (do not produce any radioactive or hazardous waste). Betavoltaics generate power when an electron strikes a particular interface between two layers of material. The Process uses beta electron emissions that occur when a neutron decays into a proton which causes a forward bias in the semiconductor. This makes the betavoltaic cell a forward bias diode of sorts, similar in some respects to a photovoltaic (solar) cell. Electrons scatter out of their normal orbits in the semiconductor and into the circuit creating a usable electric current.

The profile of the batteries can be quite small and thin, a porous silicon material is used to collect the hydrogen isotope tritium which is generated in the process. The reaction is non-thermal which means laptops and other small devices like mobile phones will run much cooler than with traditional lithium-ion power batteries. The reason the battery lasts so long is that neutron beta-decay into protons is the world's most concentrated source of electricity, truly demonstrating Einstein?s theory E=MC2.

The best part about these cells are when they eventually run out of power they are totally inert and non-toxic, so environmentalists need not fear these high tech scientific wonder batteries. If all goes well plans are for these cells to reach store shelves in about 2 to 3 years.

Here is a PDF file attached which describes the process.
It is from the company:

Oh, that's not a fake... it's yet another example of Phillip K. Dick correctly predicting the future.

Seriously, this sort of technology has been around for a long time, but only at very low power levels.  If they've been able to improve it to the point where it actually power a respectable laptop, then that's big news indeed!

Not free energy, though, because 30 years isn't forever, but hopefully darned cheap.

Cheers,

Mr. Entropy

I believe that the kind of power cells that the Lunar rovers had, were based on this kind of phenomenon.

Beta Voltaics has been around for a long time, as so do Gadolinium Solar cells, but the problem was they were ultra expensive, only NASA could afford them. The trick was making them commercial.
