The takeaway is that these ideas can be feasible at small scale, and don't need to be mega projects, requiring megawatts of power.

Here's an ideal "stranded" energy source. There is methane generated that is not being harnessed due to aging infrastructure. But that methane has value. There's not many other economic solutions for this specific problem instance, other than the solution that implements a min- bitcoin mining operation -- to first fund repairs and then to expand where the methane is used to power the mining op. (with additional plans for the future).
