I wonder what they will think of next. Probably last longer than your house.

This has no relevance to bulk silicon PV cells that make up most of the market, only thin film.

In the future, those will have to last exactly as long as your house. Because they will be your house (more likely, your office, though) I am referring to thin film PV over architectural glass. AMAT has been shipping machinery to make it for at least a decade. Don't see any takers to use it that way yet?

May be like railroads in the US replacing coal with diesel.  Took 40 years and the Clean Air Act to do that.

no one I hear at conferences talks about them.

Speaking of which. Any changes with replacing that with electrification things any time soon? Diesel creates a dependency on heavy crude, which US haven't got and has to buy from Russia (because it disapproves of Venezuela and Iran, other good sources, even more? If you go electrical, you cut your freight throughput by about 1/2, because you won't be able to stack 2x containers on top of each other anymore. You will still keep the "bomb trains" carrying extra light fracked oil saturated with gas from remote patches.

You forget the tar sands from Canada. It’s so heavy they buy US light oil to mix just to get the oil to move in the pipeline. Millions of barrels per day of overcapacity for US diesel needs. Besides there are plenty of foreign refineries in the US that have their own agenda and could care less about US politics. Why buy from Russia, Venezuela? Good question, but that decision is not based on need for heavy oil.

The tar sands are just bitumen. Awful crap, worst ROEI ever.

The article is certainly interesting but the technology is still in development with no real indication of costs. However it will very likely be extremely expensive. 300 nm coatings of whatever material is being used (I'm not about to buy the paper to find out) sounds costly to make. Granted, costs will come down but anyway a decade before it reaches commercial use, or maybe two.. worth keeping an eye on..

Mark even at $40/watt which is current cost of construction for a  fully EPA clean air certified CCGT this will be cheaper.  No fuel to buy or did you not think of that.   In ERCOT, Wind and solar pushed coal and NG based electric costs in 2007 from averaging  $67/mwh down to an average $20 mwh in 2020.

Why do you even bother to post such stupid obvious lies?  If that were true, not one single gas installation would be going in, EVERYONE would be building 10X capacity factor of wind and using all that "saved" money building power lines, new aluminum smelting plants and every other manufacturing installation commodity known to man which requires energy.  Everyone would be building out Wind turbines over every last acre of land available and rushing to fill the seas with millions of them.  They would be investing in manufacting plants to be robotically making said blades/components for the millions of wind turbines necessary.  Guess what is NOT happening.  Can't even get people to buy them without subsidies...
