In 2011 I had an idea for a ceramic coffee mug with a threaded base. then build a screw on base with heating element, battery, and QI charger. Screw the base on, set it on a QI charge pad... voila "always hot coffee". When you're done for the day, unscrew the base, put the mug in the dishwasher. Rinse, repeat.
For a year I researched getting a prototype built, castings, etc. Finally decided to just abandon it. Just drink coffee faster and it won't get cold.
Now I have 2 Ember mugs and an Ember travel thermos. Still can't dishwash it, but dang it's useful.
If Tesla is moving it’s headquarters to get away from the unfavorable political landscape of California, why would it want to hasten a shift in Texas politics to something that resembles California?
