Game Changing Crypto Patent By Walmart???

Looks like Walmart got a patent for distributing/selling your household's devices or companies devices electricity on the blockchain using any cryptocurrency that you own. It appears you can allocate however much crypto you want to your electrical grid and pay for your electricity with your crypto. If you have excess electricity, you can sell it to other people who need it. This seems like a game changer! Imagine powering your devices at home with STEEM or SBD that you earned.

Abstract for the patent:

"A method and system for managing a demand on an electrical grid is provided, including: receiving a capped total amount of cryptocurrency available to purchase units of energy from an energy provider, the capped amount of cryptocurrency being recorded in a publicly distributed transaction ledger, allocating a portion of the cryptocurrency of the capped total amount of cryptocurrency to each energy consumption device, wherein the portion of the cryptocurrency allocated to each energy consumption device is recorded in the ledger, receiving, a request from an energy consumption device of the plurality of energy consumption devices that the energy metering device purchase an energy unit, using the portion of cryptocurrency allocated to the first energy consumption device, accessing the publically distributed transaction ledger in response to receiving the request from the first energy consumption to verify that the first energy consumption device has a remaining amount of cryptocurrency."
