suncomputing

Its a line (around the world) of surplus computers, powered by the excess electicity generated by solar panels during midday. Since its always midday somewhere in the world, you can keep moving the tasks to the next computer in line. Like that you can run stuff (a website for example) only on excess energy.

At a given point in time one node will be the active node (where data is written to), it will send incremental updates to the data to the next node in line, which becomes active at the moment the previous node stops running because the excess electricity runs out.

possible line: australia -> east coast usa -> mexico -> brazil -> senegal -> ethiopia -> india -> australia

Another use of the computers would be doing batch procesing, for example a gitlab runner doing software testing.
