One of the problem with renewable energy is sustainability.  If a wind farm or solar farm goes down (usually weather related), then sustainability relies on large scale storage or keeping some HC power stations for emergencies.  Large scale storage has been a problem because at best estimates with current technologies it would have taken trillions of dollars to store enough energy to run grids for a number of hours vs. days depending on the emergency.  The MIT breakthrough discussed above is a huge step in the right direction of mass storage of energy for a renewable future.

Happy Reading.

We finished a very large defense project a few years ago that used some crazy mix designs and chemicals I'd never heard of up to that point. Concrete is a pretty complicated cake to bake these days. A lot more than average people realize. The mixes on our project had to achieve crazy compressive strengths, as well as be heat and chemical resistant.
