I don't think captchas would work out, since sites like http://megatypers.com/ exist.
Also, websites that already use captchas could just give out the captchas that they're mining instead, giving them a huge advantage.

for that it can use some different kind of captchas or anything that is not solveable by a botnet.

If a human can solve it, a group of humans can solve it for a website. How would you solve the second problem by the way?

Well . I think my words got you mislead.

I meant to use a captcha beofore submitting a block that will be a puzzle or something that can be solved by a human brain or a botnet and using captcha on top of it just to be secure and sure that the block was mined by a person.

sure, it can be done.
just figured it out...
what is the objective of the coin?
i can see clearly the objective of the method..
but the coin, .. why create it?
before i put more thought into it id like to know in what way it would better our lives.

Well the objective will be to make a coin not mineable by a botnet thus making it safe from pump n dump.
And the main problem i feel for crypto currency is hardware . Since a normal person will not be able to afford a costly GPU or CPU or ASIC for mining but definetly he can use his brain for mining . and as mining is done with brain there will be no to negligible electrical expense.
