"Possible" isn't the same as "practical". Compressed air propulsion isn't a
new idea:

Learn some engineering and thermodynamics so you can tell a good idea from a
bad one.

The point is they worked. One senile fool here keeps spouting the compressed
air car did not work.  It did.


No one said it was new. It has been used mines for about 100 years or more.


I was about to suggest that to others.  Compressed air is deal for kinetic
braking.

Computer-controlled electric regenerative braking is much more flexible and
responsive for other than straight dry road conditions.  I worked in R&D for
both antilock braking in the 1970's and the Segway so I've seen the limits
of both up close (and can't reveal details of either of them).

This discusses the subtleties of substituting controlled regeneration for
part or all of the friction brake.

The pounding you feel when you trigger your ABS shows what happens when
solenoid valves modulate brake fluid pressure.

Notice that regenerative braking can become a serious hazard on icy roads,
and to a lesser extent wet corners. There are times when only pushing in the
clutch to let the wheels roll freely allows you to regain control. BTDT a
lot, in parking lots and frozen lakes. The computer can't detect an icy
patch ahead, and sometimes even the driver can't.

"As soon as you hit an area like that when using coasting regen, your wheels
are going to lock because you have a lot of force, and then you render our
ABS system useless because the ABS can't go anything when the wheels are
locked."

You are too stubbornly narrow-minded to see the flaws in the magic tech you
have become so pathologically attached to.

 Trying to understand why things do and do not work takes real effort,
as does posting proof; posting opinions takes neither effort nor
proof.

I don't know what is more damaging about promoting "Magic" tech, the
people that are snookered in to believing the magic is not an
illusion, or the overall notion that we can all just sit on our hands
and do nothing, and wait for someone else to fix the huge energy
problems we have.

The inactive majority probably doesn't matter.

The tiny pro-active percentage capable and willing to innovate, and those
who invest in them, probably would continue with or without mass support.

It's the reactives that puzzle me, those who actively attack our current
energy sources but offer no credible alternatives.
