Big deal. There are lots of ships running around the world that have electric motors driving propellers, a lot of them a hell of a lot bigger than this. They all use fossil fuels to run their generators to provide the electricity. Diesel, gas turbine, boilers to drive steam turbines, all to turn generators, whatever, they still use fossil fuels to make that electricity.

As a blow boater electric motors have been in use for decades, number one problem is as always cost. The "best" setup as far as Im concerned is a controllable pitch prop coupled to an electric motor capable of moving the boat at hull speed and small diesel motor. When sailing the prop can be adjusted to turn the motor using it as a generator delivering power to run refrigeration and electronics. There is enough battery power for maneuvering where it would be handy to have the option of torque generated by the electric at an instant. For long distances when the load may be great the generator is run allowing for most economical cruising. As an added benefit the diesel could then be placed where the weight is most efficient. This is simply a hybrid, when you cruise and are trying to generate power using wind and sun you quickly realize just how lacking the claims for panels and wind are to provide enough power to run say an autopilot and refrigeration.
Anybody ever notice how one of these generators for the charging stations is larger than most generators that would be required to run a house?
I will keep my combustion vehicles and if necessary build a wood gasifier and operate a hydrogen generator, effectively allowing me to run without a gas station.
Typically a motor is electric (general electric) and an engine is combustion. Why then do we have General Motors making cars and not General Engines?

I believe Laser IS going to stop many threats in the future
once again the need for electric,

When Mercedes came out with the first Automobile, I bet everyone on a horse said the car will never replace a good horse. This conversation is on par with 4 stroke outboards vs 2 stroke. Entertaining. Science marches forward.

The future is electric huh? What happens when the rare earth materials become scarce. And too expense to make it feasible to make batteries? Lot of people are just short sighted on the production of and the cost of electric. Just the loss of efficiency thru charging the batteries is a deal killer. Something like 13 per cent loss from the power source to the battery. You need to educate yourself.

Don't worry Grasshopper
The industry is WAY ahead of you
many new technology's on the horizon, everything will work out just fine
https://www.greenbiz.com/article/myt...s-ev-batteries
University of Texas at Austin researchers have created a new sodium-based battery material that is highly stable, capable of recharging as quickly as a traditional lithium-ion battery and able to pave the way toward delivering more energy than current battery technologies.
For about a decade, scientists and engineers have been developing sodium batteries, which replace both lithium and cobalt used in current lithium-ion batteries with cheaper, more environmentally friendly sodium. Unfortunately, in earlier sodium batteries, a component called the anode would tend to grow needle-like filaments called dendrites that can cause the battery to electrically short and even catch fire or explode.
In one of two recent sodium battery advances from UT Austin, the new material solves the dendrite problem and recharges as quickly as a lithium-ion battery. The team published their results in the journal Advanced Materials.
“We’re essentially solving two problems at once,” said David Mitlin, a professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and Applied Research Laboratory who designed the new material. “Typically, the faster you charge, the more of these dendrites you grow. So if you suppress dendrite growth, you can charge and discharge faster, because all of a sudden it’s safe.”
Graeme Henkelman, a professor in the Department of Chemistry and the Oden Institute for Computational Engineering and Sciences, used a computer model to explain, from a theoretical perspective, why the material has the unique properties it does.
“This material is also exciting because the sodium metal anode theoretically has the highest energy density of any sodium anode,” Henkelman said.
Demand is rising for stationary energy storage systems for homes and for smoothing out the ebb and flow of wind and solar energy on electric grids. At the same time, lithium mining has been criticized for its environmental impacts, including heavy groundwater use, soil and water pollution and carbon emissions. Lithium-ion batteries typically also use cobalt, which is expensive and mined mostly in the Democratic Republic of Congo, where it has significant impacts on human health and the environment. By comparison, sodium mining is cheaper and more environmentally friendly.
Mitlin is bullish on the idea that this new innovation and others from UT Austin, including a new solid electrolyte that boosts energy storage, will mean sodium batteries may soon be able to fill the growing demand for stationary energy storage.
When a rechargeable battery is being charged, ions (such as lithium or sodium) move from one component called the cathode to another called the anode. When the battery is being used to generate electricity, the ions move from the anode back to the cathode.
The new anode material, called sodium antimony telluride intermetallic – Na metal composite (NST-Na), is made by rolling a thin sheet of sodium metal onto an antimony telluride powder, folding it over on itself, and repeating many times.
“Think of making a kind of layered pastry, like spanakopita,” Mitlin said.
This process results in a very uniform distribution of sodium atoms that makes it less likely to form dendrites or surface corrosion than existing sodium metal anodes. That makes the battery more stable and allows faster charging, comparable to a lithium-ion battery’s charge rate. It also has a higher energy capacity than existing sodium-ion batteries.
Henkelman said that if the sodium atoms that carry a charge in a sodium battery bind more strongly to each other than they do to the anode, they tend to form instabilities, or clumps of sodium that attract more sodium atoms and eventually lead to dendrites. He used a computer simulation to reveal what happens when individual sodium atoms interact with the new composite material NST-Na.
“In our calculations, this composite binds sodium a little more strongly than sodium binds itself, which is the ideal case for having the sodium atoms come down and evenly spread out on the surface and prevent these instabilities from forming,” Henkelman said.
The study’s two lead authors Yixian Wang and Hui Dong — current and former graduate students in Mitlin’s lab respectively — fabricated the material. Colleagues at Los Alamos National Laboratory led by John Watt characterized its properties. The study’s other authors are Hongchang Hao, Pengcheng Liu and Naman Katyal of UT Austin.
Mitlin, Wang and Dong have applied for a patent, along with UT Austin, on the new sodium metal anode material’s fabrication, structure and functionality.
This research was made possible by support from the National Science Foundation and The Welch Foundation.

Really...
Tesla is already using cobalt-free LFP batteries in half of its new cars produced. Tesla confirmed that nearly half of all its vehicles produced last quarter are already using cobalt-free iron-phosphate (LFP) batteries.Apr 22, 2022

Why are you guys so fiercely defending your ICE cars? I guess you like paying up the nose for fuel and supporting Russia and the middle east. Have you ever driven an EV? They are all not Tesla expensive. Starting prices are $25k for some manufacturers. Wouldn't you like to drive a car the gets the equivalent of 125 MPG and is fast as a Corvette? There will always be a place for gas and diesel autos for a long time. I am just saying the world is changing and for most driving the EV's make a lot of sense.

I wanted to apologize if I offended anybody by drifting off topic here. It should have remained about the electric powered cat & record holder. I would have a beer with anybody regardless of beliefs.

I have only ridden and driven in the P90D. Not the newest fastest or the best range . It is an impressive car. The one I rode in has been picked up for some recalls and fixes. Fair build quality I would say. Neighbor likes it but he would be the first to say it’s not going to replace his other ice cars.

It's here now just has to be scaled up, with the bill that was just passed they will have the funding $ to get big fast...
Good stock to buy
