If you don’t understand why it’s funny that a DC-powered car is called the Tesla

For those that don’t get the joke, here is why it’s funny.

War of the currents - Wikipedia

Back in the day it was Tesla and Westinghouse vs Edison as to how electricity should be distributed. Tesla-Westinghouse for AC and Edison for DC. We know how that worked out.

In fact I have always believed that the Westinghouse logo contains a reference to this battle of AC vs DC.

Does anyone here have the T-Shirt?

Ironically it’s Westinghouse money now partially backing some of these DC startups.

…add submarines to the list of things being converted to Li electrical propulsion. Interesting article that is missing some info about Japans quest: link - https://www.shephardmedia.com/news/defence-notes/japan-leads-way-li-ion-submarines/

“With the arrival of this eleventh Soryu-class submarine the Japan Maritime Self-Defence Force (JMSDF) will be the world’s first navy to field a conventional submarine powered by Li-ion batteries.

VAdm (Retired) Masao Kobayashi, former commander of the JMSDF’s Fleet Submarine Force, explained at UDT Asia in Singapore on 18 January that the new type ‘will change conventional submarine operations dramatically’.

While Li-ion batteries offered similar endurance to an AIP system combined with lead-acid batteries at low speeds, Kobayashi said their advantage was found in longer endurance at higher speeds (e.g. during an approach or evasion) thanks to their higher capacity.

Furthermore, Li-ion batteries can be recharged at sea by snorkelling, which Kobayashi described as ‘revolutionary’, when compared with an AIP system……“
