So I've noticed that my laptop's power maxes out at 120w while mining.
2x 4core i7 1.6Ghz (2.5Ghz OC)
nVidia GeForce GTS 360M
I get roughly 22-28Mhash/s (yea, I know it's not a lot...).
Running some numbers:
28(mhash/s)/120(w) = 0.2333333333333333(mhash/s/w)
60($) for 900(w) = 0.0666666666666667(/$/w)
8($) for 120(w) [if my math's right]
If you were to (lets say use deepbit) for mining with the PPS method:
[deepbit.net] ( Difficulty: 567358 )
12607.96054602647 shares to get 1 BTC @ 0.00007931496901107/share
1 share @ 22Mhash/s takes 2min:12sec [Test #1]
132 sec (2min:12sec)
1664250.792075494 sec (for 1 BTC)
27737.51320125823 min (for 1 BTC)
462.2918866876372 hrs (for 1 BTC)
19.26216194531822 days (for 1 BTC)
After I did testing with my first share, I forgot that shares aren't stable. So, that's one of the test I ran.
Okay so excuse my crappy math, but is running my laptop even worth the trouble?
