VW/Audi/ Porsche Cargo ship blaze, Crew has been rescued / Ship + cargo loss Options

[Maltese Falcon]

Just checked this news out today...Cargo ship in the Atlantic looks like a huge loss of Porsche, Audi & VW's. Crew has been rescued...looks like a total loss and an Eco mess for now (IMG:style_emoticons/default/sad.gif)

What I would really like to see are electrical powered vehicles that rely on capacitors and fossil fuel powered generators.
A discharged capacitor poses no risk, and an engine attached to a generator can be tuned for absolute maximum efficiency since it only needs to run at one RPM.
This is the way.

This is the approach my son is thinking makes the most sense. He's been researching the use in trains and some ships and has been telling me for half a year this should be the future of transportation. Think his ultimate would be a turbine powered electric. We both agree that batteries are not smart from an ecological perspective nor fiscally.

Turbines are definitely an obvious choice, but even rotary engines can be made to run very efficiently under a constant load.
One real big benefit of turbines is that you don’t need all the extra systems for liquid cooling.
I’ve heard rumors that Dodge will be putting a generator in the next Ram trucks…. But it will still be a battery electric. The only company to use capacitors vs batteries has been Lamborghini.
It’s a great point about the GE diesel electric trains. GE cornered the market with that design as it was the only train engine to meet the updated emissions and efficiency standards.

and they (turbines) run on anything van - but you'd know that with your background.
old deep fryer oil from mcdonalds or the fish and chip shop.
kerosine. not particularly fussy with what they burn.

i wouldn't mind a turbine electric car just to get the abrams tank sound in the driveway.

How about an aircraft APU? This one is small enough to fit in a 914 engine compartment.



"Measuring 12 inches by 13 inches by 24 inches, the MPU weighs 75 pounds and is rated at 10kW and 400 amps."

Tie that to a capacitor bank, and a Tesla Model S motor. The capacitor bank holds the APU output and releases it when needed for acceleration. Add regenerative braking and you increase the fuel efficiency. At home, keep it plugged in to keep the capacitors charged up.

Or better yet, use the Protean wheel motors to make it all wheel drive, and make more room for the capacitor bank.



Yes, I know it increases unsprung weight. But do the benefits outweigh (pun intended) the extra unsprung weight?


Any thoughts?

The benefits don't currently outweigh the negatives to unsprung weight, complexity, and cost. In general, having high mass and inertia rotating motors out on the corners of the vehicle doesn't help handling (except for the torque vectoring aspect) It's the opposite of mass centralization and low polar moment of inertia that the 914 has.

While it may be fun to do low speed tank turns but it's not quite that simple in a production execution given the way lawyers now dominate the industry and our society at large.

The functional safety (ISO26262) and potential failure modes of four wheel motors are a hindrance.

There are more elegant ways to achieve torque vectoring than 4 wheel independent motors. In my opinion, this allows for more high speed torque vectoring options and without all the drawbacks of 4 wheel motors. There are a ton of different solutions being explored right now - YouTube if you want more of them.
