Quote from Shane D.

From the article:

"The rubber also literally meets the road faster on an electric vehicle. Electrical motors can produce peak power, or torque, almost instantly, unlike mashing the gas pedal of a regular car, which requires gas to flow and burn in cylinders and a bunch of mechanical parts to start moving."

But it is 100% drive by wire. Soft start (torque dampened) electrical motors have been a thing for over 100 years. The kids toys spin the wheels because power is either on or off, 100% or nothing.

Quote from JedRothwell

Traction control has been a major problem with locomotives since Trevithick invented them. It was done by human skill. Starting a heavy train on an uphill grade was very difficult. Water or ice on the rails, or a swarm of locusts, made it even more difficult. The engineers had one tool to make it easier. Locomotives early on had sand domes. The engineer would pull a rope to drop sand in front of the driving wheels. Locomotives still have sand boxes.

Thinking about this some more, unless all the extra wear is somehow caused by regenerative breaking (possible but unlikely) then the advanced tire wear is affecting the vehicle mileage. Literally dragging the tires at times, by either under or over powering the relevant wheel(s).

Another possibility is that the types of persons that are early adopters of electrical cars have a much higher level of aggressive drivers than the typical ICE car owner group. I have had cars that the rear tires lasted as little as 20 minutes on the road… from 85% tread. Good thing I was friends with a tire recycler.

Quote from JedRothwell

Where did you get 5 X the rubber? I don't see that anywhere. It uses more rubber, but not 5 times more.

That was my bad. Up to twice as much rubber.

Among my many weird adventures, I came into a considerable number of heavily used, kids-type, electric “ATVs”. Working in an electrical shop of sorts these were always coming to get repaired, but only a few were worth sinking any money into. Sometimes the customers never came back after calling to see what it might cost. The rest we recycled what we could, scavenged the parts that could be used and eventually there was a decent inventory on tiny electric kids ATVs.

So naturally, me and a coworker decided to soup one up. (Customers frequently asked if this was something we could do). Many customers had actually tried to soup these up, so we were aware of the few primary problems.The tires are plastic and don’t have traction, so they spin a start-off. Adding more voltage (battery changes) just spins out the tires even more. Adding rubber to the tires and more power then shears the gears off the electric motors or transmission because they aren’t strong enough.

Lowering the voltage on a rubber enhanced ATV toy to a almost happy spot made the thing rattle and Ike crazy as the tires gripped and the transmission climbed the gears until It could force the tire to move in a erratic rhythm. And that is just in a straight line. Eventually the gears fail. The slidy plastic tires were the engineers solution to preventing the destruction of the drivetrain of the toy. The toys, as received, are durable, but fail rapidly when modified.

(Slippery tires are probably not the solution for electric cars, but who knows? Custom engineered Non-Newtonian tire rubber, anyone?)

So anyways, electric cars can control that a lot better with traction control and tons of electronics. There should be no long term reason the tires should wear out faster. I know some OEM tires are not the same spec as the replacements with the same numbers. They are often lighter for better reported model mileage, and some OEM new tires are often quieter, particularly on light trucks.

But, now pondering using up 5 X the rubber and how that fits in with total overall “eco-ness”.

Sort of like writing 10 lines of Python to replace 100 lines of C++ but now it has thousands more compiler lines and runs slower.

Quote from Curbina

The faster tire wear is kind of obvious if one knows the much higher torque of hub electric motors, and how the EV drivers like to use that characteristic for high speed up.

A viscous bearing could with help that

The neutrino flux on the surface of the Earth is a few billion per cm³, so lots already available

Mr “Anonimous” ( why anonimous? )

I never supposed fission inside the E-Cats. I never found evidence of fission.

I cannot give information of what happens inside the reactor, also if at this point I have understood what happens. With 300 reactors in operation I am learning.

Warm regards,

A.R.

Dear Andrea:

Can you tell us which books are you presently reading now during the long nights inside the computer container, when you have not troubles with the plant?

Thank you,

I think the best thing is that the Ecat makes electricity and the customer makes of it what he wants enjoying the whole efficiency of the Ecat NGU, although to couple it with existing solar systems can be a good way to make easier to exploit the exixting authorizations and grid agreements

  Dr Rossi,

  how is going on the work to reschedule the EV test ?

Quote from Qmavam

As I say, I was a watcher maybe 10 years ago when we were going to be able to by our household units at Lowes.

I gave up on the LENR idea many years ago.

But still have the question is there any real viable unit?

Also, any reason given for why Rossi's 1MW unit that was purchased on viability, was given back?

I never saw a reason. I would guess it didn't work.

                      Thanks for catching me up, Mikek

The “1 MW” plant was a fiasco such that many people are smarter and poorer, and some were shown to be incurable idiots.

If discussion is of angular frequency then the appropriate units of radians per second should be used instead of Hz

Neat stuff.
Looking at getting Ni63 from Ni62, and we have researched the cost of Ni62 in the past (around US $15000/gram), we know the cost of a battery big enough to run a car will be an serious impediment to wide adoption.

It is so simple a child could answer it.

If the lattice can absorb and diffuse millions of several MeV reaction heat pulses from each individual reaction, that material can also reciprocate by putting all the lattice heat into one individual atom until it bursts.

Sadly, I must report that her comments were character-related and have very little to do with the report itself.

Oh well

She was right about the 3 blind mice

You know where the "old geese" posts her scathing pieces in Italian. Won't link to that place here.

Alright, I’ll read through it when I get a moment.

Quote from Curbina

This was slapped onto it days ago. One can trace it, through pubpeer and retractionwatch, back to Sylvie Coyaud and her pack of nasty followers, one in particular might have been the one leading the attack, who often uses the pseudonym Smut Clyde.

I like Sylvie usually. Does she have a good argument?
She rarely arrives without dry ammo.

Quote from Paradigmnoia

That seems wrong. One typical bolt of lightening, if the energy could be captured, could power over 3 million homes for a year.

Seems Google is also bad with GW and GWh

Quote from THHuxleynew

Since they have no research that indicates such a prototype possible - they have nothing until the completion of an initial working prototype.

They (correctly - if optimistically) talk about the research results showing the potential for high energy density. Great word that.

A couple of years out isn’t much for a project of this sort, realistically.

But it is getting to be close to completion of a device time so it might be interesting soon, one way or another.

Quote from Alan Fletcher

A very good summary presentation ... The wright brothers were crazy ... We'll stay crazy!
But very short on details ... only that the output (steam) is hundred's of C, so can be used in turbines.
And they are still working on the Ikaros "engineering prototype" project.
Everything else, particularly the industrial version, is "will ......"
