“However, the power density at the centre of the Sun is estimated by theoretical assumptions only to be about 275 W/m3. As we have seen in Chapter 1, the average power of an adult male is 115.7 W. If we assume his average volume to be 70 L, i.e. 0.07 m3, the average power density of the human body is 1650 W, hence much higher than the fusion power in the centre of the Sun!”

“Along all the process steps of making electricity out of fossil fuels, at least 50% of the initial available chemical energy is lost in the various conversion steps.”
