redrumjuice Posted January 5, 2011 Share Posted January 5, 2011 These are an awesome invention! Heat balls: they work by converting electricity into heat energy, with an impressive 95% efficiency, which makes them perfect for warming specific spots in the house. They’re also absurdly simple to make: glass, tungsten, some argon to keep the device stable - it’s all very cheap to make, particularly since it’s all off-the-shelf technology. Best of all: heat balls fit in a standard lamp socket, which means that you won’t need any kind of special equipment to use them! They’re not perfect, though: the extremely small amount of energy wasted by a heat ball ends up generating photons, which means that you don’t want to look at a heat ball directly. But even that can be mitigated by using exterior shades. Really, on balance it’s a great little device, very green. I could use these in my house!
