There have been threads on TF and other forums discussing electric motors on boats and all the assorted support systems they need. Suffice it to say; powering marine electric propulsion engines for pleasure crafts never meets the economy and speed people wish for
. This is due to loss factors regarding energy creation, energy storage, energy transferal, energy use, hull drag, cumulative motor weights... as well as... a myriad of other items.
I feel bad for the souls who continue to try and make the elusive "Electric Powered" cruiser boat become a reality. Many I've seen go broke in so trying.
Electric cars - OK... at the drop of a hat it can be plugged in some place
. But, there are still loss factors regarding energy creation, storage, transference, use... etc, etc.
What most electric car owners do not realize: Although the electric "grid" is increasing reception of electricity input via solar, geo thermal, wave, tidal, wind and other "green energy" actions/reactions... dirty burning coal is still by far the primary electric energy generator throughout the world. And, although advancements have been made for cleaner burning coal; due to loss factors (some are mentioned above) there currently is more pollution created by electrically re-charging a car each and every night than by utilizing a really clean burning, efficient hydrocarbon powered engine.
That said... If enough "green energy" electricity creation devices can become amply placed into use, then the tide of pollution factors will rest in favor of electric cars.
Side Note: Being there are over 1.5 billion hydrocarbon powered vehicle engines in existence with each made of metal that can be melted for return to use in manufacturing... what would be done with the really dangerous compounds inside modern-design batteries if eventually 1.5 billion electrically powered vehicles became a reality? Just thinking out loud!
