    A good idea?
    Some other forums have this. In the future these projects will reap crazy benefits for mankind.

    I used to run [email protected] I take it this is on the same lines.

    Yeah, the two examples above are the same princple of donating cpu clock cycles (except they are for betterment of humanity rather than contacting martians lol)

    Hate to be a cynic about it but people should remember leaving a computer (or PS3) on uses a good 200W of electricity - that can be over £100 a year if constantly running (and perhaps does more longterm harm for mankind than good). Think its a great idea in principle but only if the application is worth it and works...

    It maybe true what you say but you don't have to leave the PC on 24/7.

    No, but having a team etc often encourages people to do so. Even then, with modern CPUs which can throttle down when idle, they will use far more power with distributed applications running than if they weren't. Worth remembering, but I'm not saying DC is a bad idea at all.

    Some peeps leave their PC on 24/7 anyway. It may as well be doing something extra.

    Like I said though ducky, power consumption can increase large amounts these days as CPUs come out of idle & hard discs wake from sleep etc. Remember AMD chips clock as low as 800MHz in low-power states (and consume about 20% of full-load power) and DC almost always will use all available CPU power. So its not as clear cut in 'wasted CPU cycles' as it would appear (or indeed as it was when seti/folding first appeared); this effect will increase as CPUs become more energy efficient/increase in cores (as cores will be able to be shutdown when idle).

    Beyond me. Anybody want to do the maths ;-)

    Lets just say with a modern CPU the total system will draw between 30W - 100W more than when it is idling (typically 50W) - maybe not loads, but its over a unit a day if its on 24hrs. So if you leave you PC or PS3 on running SETI 24/7 I'd think at least £30 a year would be added to your bill.

    Thats over ]100kg of coal that will be added to Drax (or somewhere similar...)
