Generally the heavier an element the easier it is to split its atom (fission). The mass of the fragments is less than that of the original atom and the lost mass is converted into energy (E=mc^2). The fission also releases more slow neutrons which go on to provide the chain reaction.
GoPro to start manufacturing in Brazil. Local production of the action cameras could lower prices by up to 30 percent. Wearable video camera maker GoPro will start manufacturing its products in Brazil to lower prices and widen its local footprint. Raspberry Pi add-ons: My experiments with camera and wi-fi.
Chinese company Xiaomi has just introduced the Â¥399 (roughly $64) Yi Action Camera, which looks like an interesting budget version of the $130 GoPro HERO, but with better specs. The HERO can do 30fps at 1080p and 60fps at 720p, but the Sony 16MP sensor of the Yi can do 1080p 60fps and 720p 120fps. Unfortunately, you're only going to be able to get one in China right now. Even if Xiaomi does try to release it in other parts of the world, I'm not sure GoPro would be happy about that design.
