Recommended Article: Thermal Storage Gets More Solar on the Grid

When we see articles about solar technology that we think are important, we like to share them.  We find this one, published by, very useful.  It discusses how to improve the reliability of solar power including how thermal storage can “even out the bumps,” the importance of grid flexibility,  the use of molten salts as a low-cost solution, storage plants in Spain and the USA, and the economic sense of PV/CSP symbiosis.

This Spring, Bring Solar Water Features into Your Garden!

The heart of any garden is the plants, but water features can make the different between ordinary gardens and real show stoppers. Whether you want simple features like birdbaths or small fountains, or a full-scale pond water garden, there are many solar products available.

And why go solar? Note: we’ve updated this this post and moved it to our store’s onsite blog, since we will soon discontinue this blog and replace it with a new one that addresses a far wider range of topics.
