Subject: RE:Hydrogen again by CentralCoaster on 2008/2/13 0:25:17 power IS A RATE of energy production or consumption. just like speed is a rate of distance travelled, flow is a rate of volume moved, etc. Wh, or kWh on the other hand, like on your energy bill, is an amount of energy. You are billed for it. Just like gallons of water you use. The water company can't bill you for gallons per minute. |
