    Thats another thing people dont understand, they think advances in technology can solve everything, unfortunately no advance in technology can create energy out of nothing or harvest energy thats not there in the first place.

    The solution is simply to suspend a doughnut of plasma at 100 million degrees Kelvin in a magnetic containment field (or electrostatically confine it...somehow) and generate nuclear fusion. Nuclear is the only viable form of green energy and fusion is the only version of nuclear which doesn't generate waste and is intrinsically safer than fission in that once the fuel source is removed the reaction stops.

    in reality fusion exist in theory (sun and stars excluded of course) and no real hard advances have been made in decades. In fact no advances have been made in conventional nuclear energy since the 1980s, the number of nuclear reactors has remained more or less unchanged since 1985. It now only provides 10% of global energy demand , it was alot higher in the 80s so we are going backwards in terms of nuclear energy. All of the brain power and research seems to be on the consumer end of energy and not on the production end. The big car companies and the googles et al are spending billions on research into electic cars, nobody is spending billions on nuclear energy. If everyone migrates to electric cars, where is the power going to come from? There seems to be a suspension of reality that this can be met by renewables and remember as dub_nerd has pointed out the world population has increased by 40% since 1990.

    I agree Joe. It's over 40 years since the American government ordered a nuclear power plant and nearly 25 since one was commissioned.
    The technology around small fission reactors is exciting, as is producing hydrogen for fuel cells from nuclear energy.
