I had a 5kW gas powered generator that more than lowered out 3 bedroom 1.5 bath house for when our power would go out - sometimes for several days (1 refrigerator, HVAC unit, microwave, electric washer/dryer, two laptops, 2 large screen TV's, hot water heater - all drawing power intermittently of course, but we never exceeded). It was about the size of a small riding lawn mower.
If I could have 5 refrigerator-sized boxes in my backyard powering my house, I would be in.

- giarc 3y agoSure, but the first LCD tv's were $50,000, now you can get one for $100. It won't be $5m forever.
- jaclaz 3y agoYep, but prototypes of (small, monochrome) LCD screens were created in the '60's, your $50,000 data point would have been probably mid-1980's, and the $100 lcd tv's probably happened in the late 2010's. I wouldn't be surprised (if this humidity device actually works and can be bettered) that working regrigerator sized units will be availably in 2040 and be actually affordable by the 2070's.
- notjulianjaynes 3y agoUnless I misunderstood, the fingernail sized object was just a prototype and the important thing isn't the size of the "cell" but the number of 100nm holes in the material. I wonder if the kind of lithography used for semiconductor manufactur would be a useful way to produce this material?
