How Green is Burst ?
-
People have been wondering how afforadable/green Burst really is - so I worked the numbers.
This analysis assumes your PC is on 24*7 - so is the differential between mining and not mining.
An average HD uses 5W when idle, and 8W when active - so a 3W difference, while mining.
So, this is where variable1 comes into play - how long do you mine for? Lets go with 30 seconds.
And there is on average 4 minutes per round - so we use 3 additional watts for 30 second every 4 minutes.
With a 4 minute average round time we have 15 rounds per hour.
With 24 hours in a day we have 360 rounds a day.
Where I am, power is $0.15 per kilowatt hour. (variable 2)
So we have: 3 watts for 30 seconds per round, or 1.5 Watt/minutes per round.
Multiply by 15 to get watts per hour: 22.5 Watt/minutes per hour - or 0.375 Watt/hours every hour.
Multiply by 24 to turn watts/hour -> Watts/day: 9 watt hours/day.
Divide by 1000 to convert to Kilowatt/hours.: 9 / 1,000 = 0.009
Multiply by price of Electricity: 0.009 * 0.15 = 0.00135
So, the cost of mining Burst over just leaving your PC on is 1/10th of a penny per day per drive.
Green enough for you ?

You should use this calculation in promotion as well, as it effectively kills any potential myths about high power usage.
