I agree. Most people would find the increase in power consumption costs more than they could make mining and the extra heat for long periods of time could well cause them real problems. I think the era of "casual" Bitcoin mining is gone now.

There might be more interest for this in the sCrypt-based forks (the "CPU Friendly" forks) since they still have a fairly vibrant casual mining community.

@Lohoris: The technology behind alternate cryptocurrencies is no different than the technology behind Bitcoin, the fundamentals of both are shared and only certain aspects of the implementation differ. Regardless, this is **not** the place for such an argument. If you asked "are the alternate cryptocurrencies 'toy currencies'" you'd be downvoted into oblivion and I think you're aware of that.

I fear you would get barely enough bitcoins to make your effort worth it, let alone get enough to redistribute to the users... that said, it can be nice to do it just for the sake of it, if you feel to.

Also, I hope that using some of the matching techniques that SETI used, I can use it as a tool explaining the BitCoin system to more users :]

# Mining as a screensaver

(Asked by: username_0 on 2012-01-09)

Strongly inspired by the SETI program, I was considering putting together a mining client that mines when a computer switches to screensaver. I know this would cost some PGU when the computer takes a nap, and would kind of defeat the purpose.

But would such a product be of interest to the bitcoin crowd ?

Would people be interested in a piece of software like this ?

I understand that serious miners would not be interested in this, but maybe, just maybe, the whole BitCoin thing would be easier to explain to some, if there was a piece of software that resembled the SETI program (which many people know or remember.)

Casual mining is not too popular or profitable. If you are not mining casually, you mine all the time and don't want to slow your computer down with anything.

Moreover, one can set the priority of mining program to be quite low, thus not impeding the functionality of the computer (when computer is idle, computer mines at full speed, otherwise it slows down to let normal use have as much processing power as it needs).

Despite that. Some casual people might be interested in playing around with a screensaver miner if it was available.
