#BTC is the best store of energy.
What if solar flames melted energy infrastructure? That's what BTC is for!
All you need to do is go outside, rip out the grass and start drawing runes on earth. If you hosted BTC node, just put computer in the center and start chanting: "Nakamoto, Nakamoto, Nakamoto...".
All zeros stored in block's hashes will vibrate, thus entire city will light up again. Running on wireless power of BTC just like in Nikola Tesla secret inventions.
