So, Google is working away on its own solar thermal technology, using cheaper mirror material, that it hopes to demonstrate internally within a few months.
But the company is also investing in clean energy technologies elsewhere – though it would like to do more, according to Bill Weihl, who oversees clean energy projects in the company’s research department.
It’s not the clean-tech ‘valley of death‘ (getting proven technologies up and running at scale) that Weihl is complaining about – it’s the early stages, which he says need more investment from the public sector – in the order of $20bn to $30bn over 10 years, in fact.
“There isn’t enough investment going into the early stages of investment pipeline before the venture funds come into the play.”
However he characterised the situation as “a little bit” discouraging – but not seriously discouraging.
Interestingly, Google.org – the philanthropic arm of the company – invests in the big US solar companies eSolar and BrightSolar, and its total clean energy investments add up to about $43.5m so far. Founders Larry Page and Sergey Brin have invested in another company, Nanosolar.
But the solar development, under Google’s research department, is being carried out separately from those solar companies.
