Litrospheres are a self-luminous micro-particle that can be painted on any object allowing it to glow without the need of any electric current. The paint was designed by MPK and is said to be non-toxic even though the betavoltaic technology that’s used for Litrospheres is derived from a radioactive gas (the company rep says that the radiation can’t escape from the paint molecules so you don’t need to worry about glowing yourself.)

It can be produced in a variety of colors. Do you want blue walls that glow? Done. Some pink trim on your house so you can see it off in the distance when night falls? Not a problem but your neighbors may think otherwise. If you think about it the practical applications extend a lot further than tripping out your bike or car. Liferafts, safety vests, hazard signs, even the lines on the road could be painted using Litrospheres and be more easily seen at night.

Enough light is emitted from the paint that it’s comparable to the light given off from a 20-watt incandescent bulb. The half-life for the Litrosphere paint is 12 years and a retouch once a decade doesn’t seem like a hassle at all.
