“Harvard University researchers say they’ve developed a new type of battery that could make it economical to store a couple of days of electricity from wind farms and other sources of power. The new battery, which is described in the journal Nature, is based on an organic molecule—called a quinone—that’s found in plants such as rhubarb and can be cheaply synthesized from crude oil. The molecules could reduce, by two-thirds, the cost of energy storage materials in a type of battery called a flow battery, which is particularly well suited to storing large amounts of energy.”
So… I finally got around to trying it out. The scallop that I scanned some time ago and have 3D printed in ABS plastic and CNC carved in wood now has been done in clay. I used a chunk of “bone” dry clay and a two stage router bit series. I’m pretty happy with it for a first go round and still have to trim and fire it.
This video shows the router on it’s second finishing pass with a finer bit:
This video gives you an idea of how thick the block is/was:
