1) If you could generate energy by fusing the hydrogen in water, how much water would you need to supply all the energy currently consumed worldwide in one year?
6.9x10^13 = Energy released by fusion of hydrogen in 1 liter of water
5.3x10^20 = World annual energy consumption
2)Suppose that we could somehow capture all the energy released by the sun for just 1 second. Would this energy be enough to supply US energy needs for 1 year? Explain.
Annual energy generation of sun= 1x10^34
Thankyou to whoever answers these or helps me. I am confused :(
+37093 1
5.3 x 10^20 j / 6.9 x 10^13 j/l = .768 x 10^7 = 7.68 x 10^6 liter of water

Need energy consumption in US to answer this......Have that info?
2) The energy generated by the Sun in 1 second is sufficient to power U.S. for approx 10.455 million years at current consumption of about 1.167 x 10^12 watts per second.
+37093 First let's find the energy out put from the sun in 1 second
1 x 10^34 j/yr Divided by 365 days/yr divided by 24 hrs/day divided by 3600 sec /hr = 3.17 x10^26 j/sec
3.17 x 10^26 j (from the sun) / 1 x 10^20 j/yr (US ann consumption) = 3.17 x 10^6 yr
= 3.17 MILLION years ! (given the numbers you gave me)
