By using radioactive materials you could be seeing 30 year batteries in your laptop without a single charge. Work being funded by the US Air Force Research Laboratory is going ahead which will hopefully see some cool batteries created.
The batteries are named betavoltaic power cells and are constructed from semiconductors which is radioisotopes as an energy source. They will be small and thin and create a reaction that doesn’t emit heat.
My fear of this is all that radiation sat on your lap… surely that cant be good for you. I am all for long life power sources for mobile devices but this one sounds plain scary. Expect to see these batteries in 2 – 3 years time.
