Lets say it does, basically turning 1 minute into an entire year.

But here's the catch, it can only be used once.
So what would you do with a year in that time chamber to accumulate over the course of a single minute in real life and at what point would you use it in your life?
Have you all lost it? (Not you OP) Study? Gym? Also sorry OP but it's actually 1 day outside = 365 days inside (and the wikia confirmed my memory, so its all good).
I don't know why anyone would want to lose a year of their life, training like Vegeta and Trunks did (to save the world), might be a good enough reason, but even for them it turned out to be an epic waste of life, since what they thought was SS2, turned out to just be a weirder form of SS (where you bulk up), and even though they had more power, they lost agility as a consequence, so they were no match for perfect cell.
Alright back to reality... sort of... Get a series of researchers studying diseases, and split them up into x useful groups, have all the equipment and resources needed moved in there, close the door, next day, next group goes in and collaborates with the researchers for a while, then they spend a year, ect, you could advance these medical research studies by 7 years in 7 days, I doubt anyones odd and selfish claims to work out and study can beat that (no offence, but c'mon! Study? Computer Games would be better).
EDIT: Lets say you could study for a 'year' in there, what you learnt at the begining, yes revision ect blah blah, and what you learnt at the end, would all basically have to be on subject matter you're currently enrolled in, wouldn't it? It's not like you could study an entire degree in that time, then just come out and do all the tests (now that might be actually useful), otherwise it would be pointless to study 2 or even 4 units...even 8.
