Fun fact, Silicon Valley was named in the 1800s because the glass in the sand would be sold to companies like Tiffany and Boston Sandwich Glass and Pairpoint and many other famous glass companies used Northern California sand to make glass windows and products. It had nothing to do with the Computer industry that followed. Bell and Packer worked together and discovered that silicate could carry a proper signal in sandwich boards. There is a massive tunnel in the East Bay (Black diamond mines) which first dug coal and then realized how valuable the silicate was in the sand.
Speedy thinks no value exists in San Francisco. somehow his redneck sandy desert region is better than California
The sand has to be contained in a thermally insulated material of course.
Using it with a steam turbine will generate more electrical power than thermoelectric for the same weight, although thermoelectric is simpler
How good it felt to pressure that timid kid at Culver's drive-thru to hand me over that sack of food even though he looked at me suspiciously and knew my name wasn't Allison.
