Who says incandescent bulbs have to waste energy: MIT design is more efficient than LEDs

Though incandescent light bulbs have been used to light homes for more than a hundreds years, and still do so in most of the world, these are ridiculously inefficient. This has prompted many governments to completely phase-them out, among which the E.U., Australia, Canada, Russian, as well as the United States. Their place has been taken over by fluorescent bulbs (CFLs), and the even more efficient LEDs. A team at MIT, however, has a bright idea that might revamp the unfavored bulbs. They’ve designed a new sort of incandescent bulb that uses a photonic crystal to recycle the waste energy. The resulting bulbs could be more power and light efficient than anything on the market right now.

What an underground nuclear explosion looks like

One this day, 53 years ago, the Lawrence Livermore National Laboratory detonated a thermonuclear device 194 meters below the Nevada desert. Why? Well, the government at the time thought blowing up a nuclear bomb underground sounded like a good idea if you want to excavate a mine. It’s a lot quicker than drilling with a lot machines. After all, mines are made using thousands of tonnes of dynamite. Why not take a shortcut and nuke the damn thing. The problem, of course is radiation. But how can you have people work in a mine if it’s contaminated with radiation, right? The logic escapes me as well.

Nuclear battery that uses water-based solution lasts longer and is more efficient

Though betavoltaics – battery technology that employs radiation as a means of power generation – has been around since the 1950s, developments thus far haven’t been the most promising. This may set to change after researchers at University of Missouri reported they’ve devised a nuclear-assisted battery, which¬†works in a watery environment, that both lasts longer and is more efficient. The
