What do we achieve by computing more and more? Warming, of course.
So why should we use heaters instead of computers? The latter are not less efficient in producing heat!
Why couldn't we replace our heaters with LANs of heating computers? This wouldn't cost so much! We might use both new or old hardware depending on our needs and resources (the most important thing is the overall produced heat!). Maybe we may get some extra incomes, or indeed contribute to good works…
Do you think I should make some study about this, including side effects of this sort of seasonal computing?
Studying climate effects on throughput of e.g. distributed computing projects might also be interesting!
