(a) Assuming that the natural abundance of deuterium given in Appendix A is reflected in the formation of water molecules, compute the energy that would be released if all the deuterons in 1.0 m³ of water were fused via the reaction ²H + ¹H → ³He + ϒ.
(b) Given that the world’s 5.9 x 10⁹ people used 3.58 x 10²⁰ J in 1999, how long (in hours) would the result in part (a) have lasted a “typical” person?
