Battery that can go 30 years between re-charges?

I read an interesting article the other day about a new type of laptop battery which should be able to go 30 years between re-charges!

The batteries

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.

Of course, the useful lifetime of a laptop is only 3 years or so before it becomes obsolete so if these batteries do come to market, you would need to be able to remove them and add them to your newest laptop.

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.

Fantastic, no more laptop burn then!

And

The best part about these cells are when they eventually run out of power they are totally inert and non-toxic

According to the article, the batteries are dur to be delivered to shops in the next 2-3 years. There is no mention of a price point though – never a good sign!

  1. This is not much different than a normal Nuclear reactor (just safer), they are mostly just batteries, this does have the advantage of creating ‘hydrogen isotope tritium’ which will be useful latter when you put it into a Tokomac or laser Fusion reactor latter on.

  2. I can see the headlines now:

    “47 dead and 29 wounded after a recalled Dell battery exploded in a crowded shopping mall today. . .”

  3. If they’ll create something like the pocket sized charger of IOGear with this type of battery, then we could actually use it for 30 years. Just plug in anything device that needs recharging: mobile phones, laptops, electric cars…. or will that be too much?
