Is your post translated with Google translate or did you made this post with autocorrect on your mobile phone? ;-) Well, if I got it right, you're asking what "Steem power" is?
Well Steem is a cryptocurrency, which you can "power up" in to your Steemit-account and while doing this it becomes "steem-power". At that point it is "stuck" in your account, but you can power it down to get it back in it's liquid form, "Steem". This process of powering down takes 13weeks (3 months). So if you power down 13 steem-power, you will get 1 Steem every week back from your vested steem-power.
Steem-power will give your votes more value and it makes you able to earn more as a curator.
Good luck!!!
