In this thread: a bunch of armchair energy scientists who think they've solved the energy storage problem all on their own.
Theres tons of ways that people with even a little brains could figure out, the problem is often cost or feasability.
A big burried water tank in my yard could be heated during the day and used to warm the house via underfloor heating at night, could do the reverse with chilled water in the middle of summer plumbed to an air recirculator with a heat exchanger. Its really simple engineering but expensive to implement.
I think an awful lot of people just dont understand the sheer scale of a lot of these problems, not the fundamentals.
It’s always economics.
There’s a joke I’ve heard that says something like anybody can build a bridge that stands, but it takes an engineer to build one that just barely stands (i.e., one where the materials and labor actually cost money).
That also reminds me of my first router - it was my PC. 10x the cost and 1/10 the features of a purpose built router, but I already had the computer and just needed to provide internet to 1 or 2 more via Ethernet.
Likewise, it’s easy to design energy storage concepts of all kinds. It’s a lot more tricky if you want it to be economically viable and see mass adoption.
