To run proof of space equals running the laptop continually right? Even if there is not much stress like overheating it will still ruin the life of the laptop, I run my laptop for 5hours a day and I'm still using since 2014, laptops aren't create to handle stress works
Some times there are people with more then one laptop, with enough space inside (hard disk HD).
This is just another way to validate a block. For what I know (burst) the process is not really stressing too much HD, it's just a matter of "free space".
Whether there is, running some sort of mining through laptop with a different consensus won't help you that much. You will just waste the laptop you will use from that experiment because the chance of breaking its durability is high, you are just lessening it's life span as well.
And for mentioning cloud mining, just avoid any of it. As for staking, there are staking coins like Tezos, NEO which doesn't require you a specific specification of a laptop or desktop because it only requires you a wallet to store those coins.
Proof of stake doesn't imply a laptop (see OP questions). You can just stake your coins with an online wallet, example, Waves or Calisto, no real need of a laptop.
