it's the demand side that kills them. You have to work both sides for it to work.

The thing I remember about Dashew's WINDHORSE in Pulpit Harbor a year or so ago, was that he was running a diesel generator middle of the day to keep up with the boats demands sitting at anchor.

You would think you could generate and store power from solar and wind enough to sustain these boats indefinitely, as Paris was attempting.

There's no carbon free lunch, yet, if you want it all onboard, no matter how much you invest.
