Can anyone remember in the mid to late sixties
a conversion to flywheel energy in motor bikes and cars?
The test bike was a tad hard to corner due to the
Gyroscopic effects and did not "lay over" as a standard bike in cornering.
Needed a hand brake to park as it would not lean onto a stand, again due to the
gyroscopic effects. Just stood there in the parking lot up right and looking
real strange with no stand down or visible sign of support.
The car proto was a different kettle of fish with
many types of rotors available.
Can any one remember these as they were easy to
re-charge just run onto a dyna tune set up so the rollers ran the rear wheel
which put power back into the flywheel. The same as the car and bike on braking
the power went back into the flywheels. Seems battery storage to produce a
controlled rotary motion via various means is a slight loss compared to
maybe a rotary system already running just needing the control which the
batteries would need as well. Not sure how far the idea got or why it was
scrapped but seems not to be about any more.
The concept of the stored energy seemed good at the
time. No PV cells needed.

Mike, I agree and certainly wouldn't rule anything out, especially
with places like Berkley Labs developing PV with 50+ percent
efficiencies.
However, emerging energy storage technologies (like the
supercap technology mentioned by Kirk), suggest a quick "fill up" and puts
into question the need for any other on-board energy conversion technologies
(i.e. solar, liquid fuel/IC engines, etc.).
I'd imagine that nearly
every renewable and alternative energy scheme being discussed is now a
possibility since fast electrical storage could turn our attention
to stationary sources and not those which necessarily need to be integrated
into the vehicle.

If the funds were there I'd
enhance the battery back and include

room to tinker.
Here's one person's expiriment:
