30 Year Continuous Power Laptop Battery

Bye bye, charger and spare batteries
Tired of carrying your laptop charger and spare batteries around? Soon you won't have to. Thanks to work being funded by the U.S. Air Force Research Laboratory, laptop batteries could have a continuous power battery that lasts for 30 years without a single recharge.
Scientists have developed the breakthrough betavoltaic power cells that 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 that is capable of fueling an electrical device like a laptop for years.
Though they sound nuclear, they're not. They don't use fission, fusion, or chemical processes to produce energy and therefore don't produce any radioactive or hazardous waste. Betavoltaics generate power when an electron strikes a particular interface between 2 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 best part about these cells is when they eventually run out of power: They're totally inert and non-toxic, so environmentalists needn't fear these high-tech scientific wonder batteries. If all goes well, plans are for these cells to reach store shelves in 2 or 3 years.

The author should research his material before taking his readers for the same ride as himself.

If this betavoltaic process can be used in batteries, then why not in Nuclear thermal power stations. If this is possible then we can have Neat n Harmless source of energy. Great Innovation..

It's great to know that the idea has been conceieved........it may take long for it to reach the average consumer....but that was true for plasma televisions too at one point of time......so I hopeful of seeing and using these in a couple of years time....cheers

Is that the picture of such a battery? IF it is then why does it say rechargeable battery pack on it? LOL

We don't know 'bout the disadvantages yet, but the price is surly going to be DISAPOINTING for most of us.

More then laptops, I hope it is customised to meet medical equipments charging requirements and will be a blessing for them

Once a battery pack has been launched, that lasts for 30 years or so, we can use it for any purpose we like.

Didn't you read it carefully? it is supposed to launch after 2-3 years........

hope so innnitially the cost will be so high that 30 year powering battery will cost u as much as u will continously buy nwe battery and charger for ur laptop for next 15 years !!!!!

This will never hit the market. imagine the loss other battery manufatures will have!!!

It might so does computers, mobile phones, internet etc which was initially though that they will create unemployment, they will create huge losses but instead they only created new opportunities.

Why don't you try to appreciate someone's innovation rather then condeming?

it want hit indian market for sure. just imagine U.S trying to lend a hand with heavy cost and improve india, what a joke. Well lucky U.S citizen , getting what government takes from other government.
