Make Your Own Nuclear Battery

A Betavoltaic cell is a device that uses a radioactive source of beta particles and a semiconductor p-n junction to generate electricity. Tritium, an isotope of hydrogen, is often used as the radioactive element. You may think that tritium is hard to obtain or even forbidden, however, recently you can find tritium in self-lightning key chains, and it is also used in watches and firearm night sights. The beta particles (electrons) from the tritium radioactive process causes phosphors in the device to glow, giving a light that can last for years.

Watch Chernobyl Get Locked Inside a New Giant Steel Dome

The 108-meter tall structure was built to replace the aging concrete sarcophagus that has contained the world’s worst nuclear plant disaster for over 30 years. Continue reading Watch Chernobyl Get Locked Inside a New Giant Steel Dome

Retrotechtacular: Head Start On Tomorrow

In the 1950s and 1960s, the prospects for a future powered by nuclear energy were bright. There had been accidents at nuclear reactors, but they had not penetrated the public consciousness, or had conveniently happened far away. This was the age of “Too cheap to meter“, and The Jetsons, in which a future driven by technologies as yet undreamed of would free mankind from its problems. Names like Three Mile Island, Chernobyl, and Fukushima were unheard of, and it seemed that nuclear reactors would become the miracle power source for the second half of the twentieth century and beyond. …read more
