I am an Electrical Engineer.  Without any adavanced education, with basic
highschool knowledge one must be utterly dumb to submit such "inventions".
This basic law is taught in like 4th (?) grade in Russia, I dont know about
here but it's one of the three major laws of phsyics - law of energy
conservation.  Energy is NOT created, it is just transformed from one form
into another, a propeller just takes energy from your gasoline engine and
when it returns into electricity some is lost due to frction, etc. losses so
this is idiotic.  Your propeller loads gasoline enginine with additional
load due to increased aerodynamic resistance, a stupid thing on your roof
makes for a great extraload on engine, while your enigine is losihng fule to
help propeller rotatte it's not restroed through electrical motor in fact
you lose some.

What's th epoint of losing fuel??  Isn't yopur purpose to save fuel?  SO you
waste gas on propeller which powers electrical motor, why nmot just save gas
and run on gas all the time?

The Hybrids use regenartyive braking because breaking energy is wasted
anyway because most people are compulsively hiotting gas pedals and then
brake at the next traffic light and this waste goes one and one because
we're all humans and want to show others the speed and dont let anyone pass
us on a city street, and blah... so accelerate/brake is a wasteful cycle,
Hybrids extract some savings from it by converting braking waste into
recharging current for the battery, as of propeller it's the same as this:

Plug a battery charger into your household outlet and charge some batteries,
then use battery while proclaiming to the world you're getting FREE energyu
what Bull sheeeite, dodnt you take energy off your househol AC??

Shhh.  Don't tell that to "feerguy9".  That was one of his proposals,
along with an impossible "electrocapacitor" idea that's even dumber
than the fully-battery-powered automobile.  (He wasn't quite dumb
enough to suggest that it would fully recharge the electrocapacitor,
but that's dumb enough.)

Personally, I'd hope for a more efficient, lighter engine,
or, given the reciprocating piston that we know today, a
continuously variable transmission that maxes out the efficiency.
It might sound funny, but it should save gas.  The batteries
in a hybrid do improve efficiency, to a point, but that
merely illustrates that the current reciprocating-piston
engine or the transmission needs improvement.

If we're extremely lucky we might get a car a la _Hard Sell_.
As described it was based on fusion power and could break the
sound barrier.

I'm not all that hopeful, though we have broken the sound barrier,
AIUI.

Pure H2 cannot compete with hydrocarbons, but in a sense hydrogen
does power cars.  (Carbon also participates, of course.  The C-C
bond has more energy than the C-H or the H-H.)

I thought the windmill on the roof of an electic car wasn't all dumb,
as long as it retracts whilst driving and is used to charge the
batteries whilst sitting in a windy parking space 23 hours of each day.
Meanwhile EV's need better batteries. Photovoltaics, wind generators,
tidal, wave and other intermittent energy sources would benefit hugely
from improved storage. I don't see that R&D funding in this area
reflects how significant such technologies are and will be -
particularly if of high energy density -  vehicles of all kinds would
be simpler, lighter, more efficient. Just compare the complexities of
internal combustion engines, gearboxes, differentials to maintanance
free, ultra reliable electric motors with only a single moving part. If
batteries  are compact enough then it also becomes significant for
energy distribution as it would become feasible to physically transport
electricity much like energy in the form of coal, oil and gas are
shipped and trucked today making remote desertlocations with lots of
solar,remote windy locations etc more feasable for energy harvesting.
Is there a theoretical upper limit to energy density of electrochemical
storage?
I can't help suspect that when the alternatives begin to look like
they're set to rival fossil fuels there'll be sudden major drops in the
price of oil, coal and gas. Just hope when that happens the
alternatives weather the storm and don't end up bought out , their
important patents ending up controlled by corporations with a strong
financial interest in seeing such technologies mothballed. ( If I
understand correctly, patent laws had the original intention of seeing
good ideas taken up widely with the inventors recieving royalties.
Somehow it seems to have become a way of enforcing monopoly rights to
good inventions and allows good ideas to shelved by those with existing
and currently cashed up interests that might face competition they
can't win out against in the "free" marketplace. The Oil industry
particularly is very cashed up, given it's low costs and high profit
margins and will use it's wealth to ensure ongoing profitability
through every means - from buying political influence to PR campaigns
to buying out upstart rivals.)
