Eli Hariton's new space-aged designs of a sky high solar facility have re-ignited excitement over such a pie-in-the-sky idea.

Recently, we gave word about PG&E partnering with Solaren to develop an incredibly expensive and potentially promising facility that would capture pure, unfiltered sunlight 24/7 and beam it down to earth in the form of microwaves.

It's more than a battle of namesake between Vinod Khosla investment Calera (not to be confused with Caldera, which bought parts of Linux vendor SCO) and scientist Ken Caldeira; it's an accusation of fraud and misrepresentation… to children!

Sparked by a new exhibit at the California Academy of Sciences detailing the controversial Calera process, the conveniently confusingly-named Caldeira, a Carnegie Institution scientist who has studied this exact process, started a Google Groups discussion challenging the scientific claims of the exhibit.
