A group of scientists at MIT have found a way to manipulate water-dwelling micro-organisms into producing more hydrogen, which they anticipate will be the most viable, clean fuel in the near future. These micro-organisms tend to produce self-sustaining sugar over hydrogen, but by adding a bioengineered enzyme into the mix scientists believe they can manipulate the organisms into focusing more on hydrogen production.

This chandelier lamp is called Virtue of Blue and is made up of hundreds of solar cell butterflies that absorb energy and light up the bulb around which they appear to flutter.
