This is silly, but I'll add my take:
This would create the incentive to have chips that are idle 50% of the
time and work harder 50% of the time. This means miners would buy twice
the chips to use the same amount of power, for example.
This in turn means a greater portion of your operational costs are spent
on chips, and a smaller portion on electricity, reducing the incentive
to use cheaper power and turn off when it's expensive, because you need
to recoup your investment. That seems like a bad thing.
Here's my proposal: if you want a PoW algorithm that's better for the
environment, make one where the chips are easier to manufacture, so
power costs become a greater portion of miner expenditures. Maybe
SIMON/SPECK would do it. It could also incentivize someone to find that
NSA backdoor...

Hello,
Bitcoin should create blocks every 10 minutes in average. So why do
miners need to mine the 9 minutes after the last block was found? It's
not necessary.
Problem: How to prevent "pre-mining" in the 9 minutes time window?
Possible ideas for discussion:
- (maybe most difficult) global network timer sending a salted hash
time
code after 9 minutes. this enables validation by nodes.
- (easy attempt) mining jobs before 9 minutes have a 10 (or 100 or just
high enough) times higher difficulty. so everyone can mine any time but
before to 9 minutes are up there will be a too high downside. It is
more
efficient to wait then paying high bills. The bitcoin will get a
"puls".
I dont think I see all problems behind these ideas but if there is a
working solution to do so then the energy fud will find it's end.
Saving
energy without loosing rosbustness.
