"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."To good to be true? According to this article here are more about this super-duper battery:
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.
"Totally inert and non-toxic", that would be a really achievement if it is indeed true! Will we find it out in 2 to 3 years? But, remember, we need to wait 30 years to find out its "totally inert and non-toxic" properties as an "totally inert" status. That's a long time for human memory, however, these are good marketing words for increased profitability.
