Preface On October 11, 2019, an explosion rocked passenger ferry Ytterøyningen while dockside at Sydnes, Norway. The vessel, recently refit with a lithium-ion battery hybrid drive, is part of the new fleet of low and zero emission vessels being deployed across Norway and other parts of the world. The vessel was at dock having been pulled from service the night before due to a fire in the lithium propulsion batteries; a condition known as thermal runaway. The root cause of the fire is still to be announced, but the secondary explosion caused significant structural damage to the vessel; likely a result of a buildup of flammable gasses below deck. Thankfully none of the 15 people admitted to the hospital were badly injured and all were soon released.

At absolute zero?
“What value is this on a ship which would stop using its drag or with engines in reverse?”
It was most likely LNG.
The are testing battery systems. Just a guess but they could charge while cruising at sea and thus reduce import emissions.
in-port
“Not my line of work, but methinks this is close to perpetual motion?”
Why?
And what is a kw/h?
——And what is a kw/h?——
Energy dissipation or usage rate
“We need some land guys over here stat!”
I think the real driving force is the emissions while in port. Conventional diesel or bunker fuel emissions in port can be very bad because ships don’t have the same emission controls as stationary sources.
Of course, the companies can pitch “Look! We don’t use any of that evil, stinking carbon” and “Look! Green, green, green!!” to a gullible public.
Whenever I order a product that contains even the smallest Lithium Ion cell, it is shipped UPS Ground and takes much longer to arrive.
“Energy dissipation or usage rate”
Bad guess.
“When improperly collected, the voltage increases times the number of batteries.”
Do you mean ‘when properly connected, the voltage increases times the number?
“The U.S. Post Office won’t accept packages containing them.”
The will, with restrictions.
Queue the “Simpsons” character Nelson : “Ha, Ha !
” In other news, importing large numbers of Islamic fascists into your country causes significant thermal runway. “
Oh, c’mon. Who in their right mind would do that ?
It’s inconceivable.
While the information about safe handling of lithium batteries is not generally known, it is available.
For example, to fully discharge a lithium battery and render it truly safe, you drop it into a container of salt water for 24 hours.
“At absolute zero?”
Sailboats have been using water and wind driven Generators for decades!
Amazon.com
How does a water driven generator work? Dropped alongside when under wind power?
Use Communist Chinese lithium-ion battery technology, fires and explosions happen. A lot.
Unlike applying brakes on a car with regenerative braking when needing to slow down, this is like driving with a foot on the brake all the time to regen the battery.
More than a bit of lost motion in the system.
And what is a kw/h?
kWh or sometimes kW⋅h, about the slash?
