**1.They claim that it is possible to store over 500 GW of power (presumably for part of a**

day) in pressurized caverns of 535 billion cubic feet. If the storage time is one half day,

what is this in Joules per cubic meter?

**2.Watt=J/s**

GW=1x10^12 Watts

1 cubic meter = 35.31466672 cubic foot

GW=1x10^12 Watts

1 cubic meter = 35.31466672 cubic foot

**3. 500GW/535 BFC= .934 W/CF=.934j/s/CF=aprox 2592000J/m^3**

Im not sure if the solution i worked out was correct or not just wanted to make sure.Im not sure if the solution i worked out was correct or not just wanted to make sure.
