Near Granada, Spain, more than 28,000 metric tons of salt is now coursing through pipes at the Andasol 1 power plant. That salt will be used to solve a pressing if obvious problem for solar power: What do you do when the sun is not shining and at night?

The answer: store sunlight as heat energy for such a rainy day.

Part of a so-called parabolic trough solar-thermal power plant, the salts will soon help the facility light up the night—literally. Because most salts only melt at high temperatures (table salt, for example, melts at around 1472 degrees Fahrenheit, or 800 degrees Celsius) and do not turn to vapor until they get considerably hotter—they can be used to store a lot of the sun’s energy as heat. Simply use the sunlight to heat up the salts and put those molten salts in proximity to water via a heat exchanger. Hot steam can then be made to turn turbines without losing too much of the original absorbed solar energy

Let’s not follow the politically correct lie that manmade CO2 emission cause “dreadful”
climate disaster! While the new water to hydrogen catalyzed reaction was shown at MIT, the MIT climate specialist Prof Richard Lindzen and others demonstrate that man’s CO2 does not drive global warming! (Solar flare output is the key factor, and demonstrated correlation is really that high air temperature causes release of CO2 from the sea as deep temperatures slowly warm up in delayed reaction). See the video on http://www.youtube.com

“The Great Global Warming Swindle”

However I’m looking at using various energy sources (even coal fired boilers) in some remote locations subject to long winter darkness (and little wind), and need ways to CHEAPLY store energy for electric circuits. And this new catalyst needed only some catalytic cobalt and phosphorus may be of interest for this. IF it can be dome more cheaply than other methods!

What else is hot for such a system???

I am brand-new to blogging and in actual fact loved your internet site. My goal is to bookmark your site and keep checking get you started. Thanks for sharing your internet site.

Just saw “This New House” on DIY TV today with this Solar Project highlighted. If you need a residence to try this experiment on, please contact me! We live in Southern Indiana and have sunshine, but not every day. Any energy savings from the sun would be welcomed! We don’t have enough sustainable wind to make wind energy viable. Has the price gone down any making it reasonable for the average homeowner? The $100,000.00 mentioned today is terribly expensive for most of us! Keep up the research Dr. Dan Nocera!

Reading this article I notice that the comments are coming from the US only. And none are very good. Fortunately, there are many other developed countries in the world that do not keep their citizens in this paranoia paradise that everyone is to get them, and the science is marching fast forward. The benefits of that are that the science is open and accessible to all. So, it may warm your hearts to know that while you are struggling through unprecedent crisis and problems, we are coming up with solutions. nano particles lithium batteries that are minimum ten times better than those made in US, efficient desalination processes and machinery that is the most advanced currently in the world, with no issues like thos e in the US, better cars, petrol, diesel, hybrid, electric, even hydrogen ones (although germans are there on the top with Japan), you name it.

And yes, we have cheap and super efficient catalysts for standard electrolysis too. The life couldn’t be better in the rest of the world.

Hi, Greg — look at the bottom of the post. This was published on August 1, 2008.

I’m afraid there is a problem with all the hopes that this might decrease the size of the infrastructure. Suppose this catalyst is mass produced and everyone buys one. Will they also buy the alternative energy source? I think not. Instead they’ll store up energy from off the grid. Now they’ll store energy at night when energy is cheap and not needed–NOT DURING THE DAY when the solar power might be working. I suppose they might buy energy from the grid during the winter when it’s needed at night to warm; but there will be less excess energy and etc etc.
