Dr Kelvin Kemm: Nuclear waste storage ….. no big deal

Nuclear power will be the future. There is no doubt about it. Nuclear is the cleanest, greenest, cheapest, safest, energy source ever. There is no doubt about that, no matter what anyone says. Also, just look at the energy density of sugar, coal, petrol, and uranium. Sugar contains about 20 megajoules per kilogram, coal 25, petrol 50, but uranium is 76,000,000. What this tells you is that you can carry your lifetime supply of electricity in a shopping packet, if you’re carrying uranium.

Dr Kelvin Kemm: Solar for the soul or for the senses

The Sun has mystified mankind for centuries. In days long gone, primitive people worshiped the Sun or a Sun God. But much more recently, in the later 1800s, people were still mystified because by then science had advanced a great deal and physicists had acquired a significant understanding of thermodynamics and energy. They knew that thermodynamics states that energy can neither be created nor destroyed, and it can only be converted to another form. They also knew how to calculate the heat emitted from burning coal, wood, or anything else.

Dr Kelvin Kemm: Alice in Hydrogen Land

At a shopping mall or amusement park one can see vendors selling balloons filled with Helium. Kids love them and dance around trailing their balloons, which float above them. From time to time some kid accidentally lets go and you see the balloon soaring high into the sky, to the delight of many watching, but to the heartbreak of the kid. The balloon soars up into the sky because it is filled with Helium, and Helium is a gas much lighter than the Oxygen and Nitrogen which make up most of the atmosphere.
