A recent scientists study revealed found,that the cold nuclear wastes can be an effective source of clean energy. To prove the viability of the idea, experts at Bristol University have created a battery that runs on the radiation wastes. Researchers have established that if an artificial diamond is placed in close proximity to the radiation source, it allows you to receive current. Such diamonds can produce current for thousands of years, they can be used on the spacecraft, in implants and other devices where battery with a long period of work is vital.
Diamond battery on radioactive waste, containing 1 gram of carbon 14 can produce 15 J. daily. This level of production is theoretically designed for 5,730 years. Thus, the total energy capacity of the battery recites 2.7 Tera Joules.
Most likely, these batteries will not appear in phones and smartphone of them do not charge, but such electrical diamonds are quite suitable for small devices. Well, and the radiation is not more from them than from a banana.
