Laptop Battery Worries Over?

[Racoon]

Some of you may already know this, but for the less technological savvy people including myself..

 

Imagine only having to replace your battery every 30 years without a recharge! :eek2:

Well, it could be a reality in 2-3 years..

Betavoltaic batteries. :evil::(

 

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

 

Pretty neat huh?

I personally liked toshiba's development for the Japanese Navy, they were designing a battery that gets 90+% of its charge in the first 5 minutes of charging it, and after 10000 recharges lost less then .01% of its total capacity...

 

but this will be neat, do those neuron beta decay batteries come in a rechargeable version?
