If you don't like how something's done, do it yourself. Google is taking that idea to heart when it comes to solar thermal technology. The company has been disappointed with the progress in this sector, so it's developing its own mirror technology that will supposedly make solar energy cheaper by at least half.
Google is experimenting with different materials for making the mirrors, trying to find an efficient and cheaper solution. The company wants to cut the cost solar thermal installations by half, but hopefully by 66 - 75 percent. Currently, a 250-MW solar thermal installation produces energy at a rate of about 12 - 14 cents/kWh. The company would like to develop a product that would lower that cost to 5 cents or less per kWh.
The company is planning on having a prototype ready for internal presentation within the next couple of months. Then they will perform aggressive testing to make sure the technology can withstand decades of wear.
Google is also working to develop a gas turbine that would run on solar power instead of natural gas that could lower electricity costs even further.

There are a large number of companies already involved in solar thermal research. Why if Google does some solar thermal research would it be newsworthy? Google has not actually discovered anything, and they might never find anything.

Google is taking over the world. While I don't necessarily like this idea I can think of some worse companies to do it. Google is at least showing up on this website every once in a while: powering servers with power from the ocean waves, investing in geothermal power, and now with solar thermal research.
@Bill
Why is it news worthy? Google is a young, ambitious company with LOTS of money. These are good qualifications for making leaps in technology.

I'm all for anyone and everyone getting our world where we need to be. Two thumbs way up for Google.

Some of my stocks are in Solar-only companies, so this might not help them (it might actually hurt them) but Google's reputation alone (a pretty positive one) can help the industry become more mainstream. The free market will not take care of this problem alone, but when forces like Google make headlines in solar, it is a good thing.

Google is doing more in one year than ExxonMobile has done in regard to renewable energy for the past 20. Consider that Google is not an energy company!!!

How can you develop a gas turbine running on sun? Is the sun going to make gas from ... what??!?!?!

Its great that google is looking to make renewables competitive but as bill said many other startups are doing the same thing. I would rather see google make significant investment in some of these companies without the expected ROI in 5 years

Sure -- drive the competition! Nothing wrong with that.
Honestly, though, I don't see why they're getting into this sector, given that they've invested in numerous other solar thermal companies already (eSolar, Ausra), and those ones have gotten pretty far along this path already. I mean, eSolar has its first plant open already and an armful of deals lined up, and I assume Ausra and Brightsource are doing similarly. Kind of a weird move. Then again, maybe Google thinks this is their last chance to get into the energy sector?

There is such a thing as a closed cycle gas turbine that uses air or some other gas as working fluid rather than steam. You can read a little bit about them at http://books.google.com/books?...avlinks_s. Whether or not such turbines can outperform steam turbines is questionable, however.

Why can't regular ol' scientists and engineers come up with these solutions as cheaply and efficiently as a massive private corporation? We should all be thankful that Google at least appears to have benevolent purposes, because they seem capable of pretty much anything in terms of technical solutions to serious problems. Monopoly, anyone?

GM is a good example of why a Google minded company is needed to move us off the dime. GM was convicted of conspiracy in their killing our nations electric trolley systems and also crushed all the EV-1 electric vehicles because "no one wanted an electric car". GM was just given billions of your tax dollars so they could continue crushing superior companies and technologies. Coal and oil are no different.
So if a Google does not come along to break the hold of these all powerful, self centered dinosaurs who will?

It is the failure of US capitalism and Government oversight itself which has prevented the US from re-configuring itself.
Anyone who thinks that Google is a white knight is delusional. That company is exploring all avenues with which it can monopolize or control commercial sectors. Google would love for you lemmings to pay them to read books instead of going to a public lending library, they track your online behavior in order to sell the data to marketeers.

First off it is great that Google is spending its money trying to improve performance and price. There is nothing new in this that will in anyway hurt either Esolar or Brightsource, it can only help them out. The current mirrors used in trough systems are very expensive. They use curved special glass and have a silver backing. They are very efficient but cost over $200 a pop. The current 80 MW plants (would be about 100 MW’s now because of better system efficiency) use over 190,000 of them. Anything that would help out cost, while maintaining efficiency, would be very helpful.
Not sure about the gas turbines without natural gas but I have heard some rumors about them. They are now building a solar field, in Florida, that will assist the steam side of a combined cycle gas turbine. I believe it is about 50 MW’s. There is also a project in California, that has applied to be built, that will combine a biomass plant with solar.
Not sure where you get the current price for a 250 MW solar plant as none exist at this time.

I think Google's plans will boost solar businesses. Obviously, they will have to employ solar companies to do this work and that will lead to more jobs in the solar industry.

Not a new invention, DOE as been looking at them for some time.
5 cents a kwh is cheaper than coal. If they do THAT by the end of the year, Google stock will be worth more than Exxon.
Whatever it takes, we need it.

If you make the mirror of front-silvered or gold-sputtered plastic, and can hold the specs for shape, and cover the reflective surface with a thin layer of magical clear plastic, similar to the clear coat on automobiles finishes, it might be cheaper than glass. My eyeglasses are really weird lightweight optical plastic on titanium frames, for instance.

Solar companies should be excited about Google's efforts to reduce the cost of solar. That is one of the biggest market barriers, isn't it? Why not make it more accessible for everone? This will not reduce market share for existing solar companies...it will make the solar market larger overall.

I think this is great - more large corporations should start thinking this way. Thanks, Google!
