Betavoltaic batteries can power your laptop for 30 years without recharging

The worst part about laptops or any gadget working on batteries is the constant hassle of recharging. Fuel Cells currently in development promise upto 40 hours of continuous power supply however a new technology being developed by the air force can render them absolutely useless – Betavoltaic batteries as they are called can provide your laptop with power for an unbelievable 30 years without recharging. 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. Thought they may sound nuclear, they are not, so your laptop battery cannot blow up with the entire neighborhood.
