R-Walker Selfsustaining Free Energy bike from Mexico

Yes, they have not yet answered my emails, cause they are probably just attending this conference
in Romania.
Hopefully we will soon hear more about it.

@MarkE,
Please stop the negative comments about it, until we get further informations.
The
solar headlights were added later.
In the first pictures they did not have any lights at all, so they just added them probably for convenience
and also to not disturb the other circuitry.

The control box for the whole system seems to be below the lead Acid battery...
A little hard to see, cause we don´t have good pictures of it yet..
I only grabbed a few pictures out of the first video.

Regards, Stefan.

Stefan, like most here I think that some editors misunderstood what these students put together and have printed claims that are completely wrong.  Eventually, we should be able to get enough material translated to see what it is these students actually claim and maybe even we will get to see how the scooter actually performs.  For example they may have bought or built power conversion electronics that accommodates motor generator voltage by boosting the battery voltage.  They may also have done something more clever than usual to get superior efficiency during regenerative braking.  Each of the super capacitors can store about 100J at 12V.  It is much more storage than needed to buffer motor PWM cycles, but it is much less than what would be needed to buffer the battery against an acceleration cycle lasting more than a second or two.  I think it is conventional technolgoy with a conventional result, but I also think it is good anytime kids work on real world technology problems.  The process teaches important skills even if the end product doesn't shake the pillars of heaven.  At any rate we will eventually see what if anything is unusual.

Hi Stefan. Here is a photo from today of Victor Ricardo Garcia showing the R-Walker at the
Infomatrix competition in Bucharest, Romania.

This is the kind of project where part numbers for components should be readily accessible since it was once parts itself.
Building a duplicate of the electrical system attached to a piece of electrical conduit rather than to a scooter frame would
be very educational. It would be quite easy for them to swap components when something doesn't work.

Use the second motor to spin up to the primary wheel speed of 2000RPM and should this cause the system to become
self running. I dislike it when this type of project doesn't seem to follow a logical flow. There other thing is the use of
combustion terminology where there is apparently no combustion.

  Most likely, the bike is not totally self sustaining, but yet can recharge itself to some limited degree.
I notice how they don't show a clear shot of the electric motor,  nor what the regenerative charging part is, or how it works.
Even then, it may be a start in the right direction, but it would also be nice to know how it's all set up.
  Not bad for a start...

   Look at something like the Tesla S, which only runs for 12 minutes, all out, before
draining the batteries to the point of them causing the shutting off of the input to the engine.
