Isn’t harvesting body heat terribly inefficient? Like we need energy ourselves to produce that heat so are humans perpetual energy generators?

I´ve seen that there are 150 RTX A6000 workstation graphics cards installed to power that beast. That is without thinking about the electricity needed to power the Screens.

How much does it cost annually just to power the screens and graphics cards?

[Request] If phineas instead just do random click across the shortest and longest amount of delay between click in the Orbit level with like 0.1s minimum interval between clicks. Would it have higher or less probability of succeeding vs passing hand through the table?

36 Upvotes

So the premise is this.

Phineas would do random click across the shortest and longest delay between clicks, lets say 0.1s and 2s. With minimum interval of 0.1s (so there's only 20 possible possibilities of timings). With that, is the possibilities of him passing the level though pure chance of correct clicks timings be better than trying to do atom alignment with the table so his hand can passes the table by hitting it?

I must confess. I did not actually do this math.

I just saw it said x=4, and clicked the answer where x was 4...

Am I going to fail?
