re: Kites could pull cargo ships across seas to lower carbon emissions

Perfect insight into the energy demand deniers. They fail to understand that engineering by definition involves economics and efficiency.

They have blown $7 trillion dollars on green nonsense for a 4% (debatable if even 4%) reduction in the proportion of fossil fuels that make up global energy supply.

In addition, If that $7 trillion was spent on fossil fuel extraction, we could have reduced fossil fuel prices materially and had more energy for the 3+ billion people that are burning dung to survive.

This simply doesn’t work, it’s amazing they think they can somehow politic their way around thermodynamics and physics.
