Hiroshima nuclear explosion in 1945 had the energy equivalent of 21.5 KT of TNT exploding, ie. as per Einstein, energy what a gram mass of matter would release. A kg mass of matter releases 21.5 Mega Tons of TNT energy equivalent. The sun releases app 10,000 Mega Tons of TNT energy equivalent every second, 10 million times Hiroshima .. and sun is the smallest of stars known to mankind.
Are we really energy deficient ??
