I am old enough to remember the rivalry between VHS and was told that Betamax was the way to go so I bought one. Bad decision.
I am doing a bit of research into green fuels, beyond what are generally in common use today. There seem to be three possibiities. Methanol, Ammonia and Hydrogen. All have disadvantages, the most common being that it is cheaper and less harmful to the environment to continue to use hydrocarbons if one takes into accound the manufacture of them. But the way the world works one of them will eventually become common to power marine craft. So my question whether we are at the Betamax moment. Does anyone have a view on which is to become the VHS?
