Efficient energy storage for renewables is an area that may provide sudden and significant change. One recent project based on flexible flywheels with digital dampening seems interesting: https://www.kickstarter.com/projects/1340066560/velkess-ener...

I spent the rest of the spring designing and developing this new damping approach. Basically it amounts to a very sensitive array of sensors that are all hooked into a computer which is able to watch the data streams in real time to diagnose these phenomena. The computer is then able to apply precisely timed forces to the apparatus at key locations to get rid of these vibrations. I got the idea by reading an article on identifying and eliminating the vibrations that happen in the beams of big particle accelerators like CERN and the Large Hadron Collider.

Now entering commercial production as http://www.velkess.com/VelkessLDatasheet.pdf and http://www.velkess.com/VelkessADatasheet.pdf




Cool. Energy storage certainly counts. It's a nicely left of field concept, as a bottleneck remover.

If energy storage can get onto a rapid improvement path, all sorts of options might suddenly be feasible. But I have to say that the idea of a flywheel storing enough energy to power a house sounds scary, never mind anything bigger. What happens if the stabilisation fails somehow?


Allegedly from a comment during development on their kickstarter, an experienced fire engineer helped to design the four layer security system - running the flywheel to breaking point never damaged any layer except the innermost. However, this is yet to be seen in production, so YMMV.
