US Funds Aggressive Tech To Cut Solar Power Costs 272

coondoggie writes "The U.S Department of Energy wants researchers and scientists to 'think outside the box' and come up 'highly disruptive Concentrating Solar Power technologies that will meet 6/kWh cost targets by the end of the decade.' The DOE's 'SunShot Concentrating Solar Power R&D' is a multimillion dollar endeavor that intends to look beyond what it calls the incremental near-term to support research into transformative technologies that will break through performance barriers known today, such as efficiency and temperature limitations."

    I admit to reading the article (sorry), thus I know it's 6 cents.

    Even if solar panels were free, solar electricity still has a high hurdle to jump before it becomes competitive with other sources.

    The costs include the mounting structure and the power inverter.

    The article isn't about electricity from photovoltaic panels mounted on roofs. It's about large industrial scale solar concentrators like this one. [ieee.org] It has the potential to be cheaper than PV generated electricity and it keeps producing electricity after the sun goes down.

    Um no. The article is clearly talking about LCoE, the basis upon which all industrial power pricing is compared.

    If that were the number they were referring to, you might have a point. But it's not, and you're wrong anyway. STC measurements are normally done at 3rd party labs for just this reason.

    The tech belongs to Germany, Japan, China. They did the research and raced to the bottom with production lines churning out many solar panels.

    The key ingredient to solar panels (polysilicon) has a very strong U.S. player in the form of Dow Corning's Hemlock Semiconductor.

    It doesn't matter, all of those companies would have eventually ended up in the same place - having to interoperate. They would have come to that conclusion eventually on their own, but if gov't wasn't allowed to spend money, how much would have been saved?

    How many projects does a government start, that NEVER do anything, never end up with any outcome at all? That's all wasted money and it's all hurting the economy, not helping it, because the failure is not limited to some small private entity, it's distributed to everybody.

Do not underestimate the value of print statements for debugging.
