Betavolt’s BV100 is a tiny nuclear battery designed to generate electricity for up to fifty years. A normal lithium battery stores power, then needs charging again once it runs out. The BV100 works differently. Inside, nickel-63 slowly decays and a diamond semiconductor converts that energy into electricity. Because the nickel decays so slowly, the battery can keep producing power for decades without charging. It currently generates 100 microwatts. That is enough for small sensors, medical devic

The Light Bulbs You Need to Get Rid of IMMEDIATELY (New Research). The light bulb above your head right now may be quietly STARVING every cell in your body. Scientists just gave it a name: 21st century SCURVY. In less than one generation we deleted 95% of the natural light spectrum from human life, and almost nobody noticed. Press your finger over your phone's flashlight and you'll see a deep red glow. That's near-infrared light passing straight through your hand - the exact wavelength band that
