Via ScienceDaily:

Imagine if the next coat of paint you put on the outside of your home generates electricity from light — electricity that can be used to power the appliances and equipment on the inside. A team of researchers at the University of Notre Dame has made a major advance toward this vision by creating an inexpensive “solar paint” that uses semiconducting nanoparticles to produce energy.

“We want to do something transformative, to move beyond current silicon-based solar technology,” says Prashant Kamat, John A. Zahm Professor of Science in Chemistry and Biochemistry and an investigator in Notre Dame’s Center for Nano Science and Technology (NDnano), who leads the research.

“By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we’ve made a one-coat solar paint that can be applied to any conductive surface without special equipment.”…

    Yet another solar technology which will likely never be available to the consumer market.

    With the rate of announcements about new solar breakthroughs, you’d think it would be easy as pie to get a cost effective set of solar cells for your house.

    Not so.

    This stuff seems to get its 15 minutes of fame in the media, then never be heard from again.

    One tricky move I’ve noticed is that “Energy Companies” invest in the product after it reaches a fruitful stage of development, with the condition that the product only be sold to “Energy Companies” and not the consumer market.

    Then, once the product is ready for market it just sits on the shelf because consumers can’t directly buy it.

    It took me a very long time to understand the value and power of rearguard actions.
