I don’t think I have ever heard of proof of space, is it the same as proof of stake?

Completely different things. In Proof of Stake, the network (roughly!) allocates rewards for validating transactions based on the amount of coins you have, i.e., your stake in the network. In Proof of Space, the network allocates rewards based on you proving that you are really storing the data you were supposed to store. If you fail to produce a proof for some data item the network expected you to have stored, you lose the reward.

    Yeah, that is called proof of storage in Filecoin: https://spec.filecoin.io/#section-algorithms.pos https://spec.filecoin.io/#section-algorithms.pos

  Another important wrinkle is that Chia’s proof-of-space needs you to prove you’ve stored the right cryptographic noise - rather than, for example, any useful data.

    Another proof of waste shitcoin. Just what the world needed.

They are different. Chia isn't Proof of Stake because how many XCH has no impact on your odds of winning more. https://en.wikipedia.org/wiki/Proof_of_space https://en.wikipedia.org/wiki/Proof_of_space https://en.wikipedia.org/wiki/Proof_of_stake https://en.wikipedia.org/wiki/Proof_of_stake

  Sorry, dropped a couple words: "how many XCH you have has no impact"

No - it’s a bit more like preprinting big ranges of lottery tickets, that require giant look-up tables moreso than raw computation. So it requires the dedication of some hard/rivalrous real resource, storage space, other than either strictly energy/CPU (PoW) or the protocol’s own tokens (PoStake). See the Chia ‘Green Paper’ for more details.
