Solar cells as light as a soap bubble

It's amazing how quickly solar technology is advancing.

Solar cells as light as a soap bubble

Imagine solar cells so thin, flexible, and lightweight that they could be placed on almost any material or surface, including your hat, shirt, or smartphone, or even on a sheet of paper or a helium balloon. Researchers at MIT have now demonstrated just such a technology: the thinnest, lightest solar cells ever produced. Though it may take years to develop into a commercial product, the laboratory proof-of-concept shows a new approach to making solar cells that could help power the next generation of portable electronic devices.

That is the promise of solar. Seems like every decade major progress in made in cost, weight, and efficiency.

I think solar and nuclear fusion will eventually be our main sources of energy.
