R-Walker Selfsustaining Free Energy bike from Mexico

[tagor]

They could ride the thing downhill to charge it, and then push it back up hill to preserve the charge.

LOL

What about the "spark" ?


Why do they need a spark?


I'm not an electrician of any kind, but could they use the spark to charge the supercaps, with high voltage?
And slowly funnel this back in low voltage to the engine?


( Sorry if this not makes sense )

No it does not make sense.

Hi Stephan,
I usually do not comment this kind of news, but in this particular case I think I know what happened as i myself work in and with the media

This is my theory:
A young journalist from reuters is in mexico, and found this story. She probably was there for something else but found the subject interesting.
She goes to the place and talks to the people at the university.
Her spanish is probably not perfect and the people are enthousiastic and... exagerate a little bit.

Example:  this bike's wheels might  turn at 2000 rpm.. but i really doubt you can "cruise" at 60 km/h with those small wheels.. there would be the smallest stone on the road you would fly meters away.
He probably meant it has an autonomy of 60km...  (in spanish he probably said: you can go 60km) and the journalist thought he meant 60km per hour...

doing 60 km with one 12 volts lead acid battery is extremely efficient...

What also struck me is what the guys are saying.

Let me quote:


VICTOR GARCIA, SAYING:

"The project is a prototype that generates its own energy as it goes along: As it goes faster and covers longer distances,
it generates more energy. In that way, you don't have to charge the battery every 6-8 hours."

OK.. but he does NOT say you dont have to charge it at all!!!

Garcia calls the process "auto-sustainability."
IMHO this is the translation mistake. He probably means something like: "it produces energy that is reinjected into the system"


RAUL GRAJALES, SAYING:

"With this, we have reduced the use of 200 batteries a day and seventy percent of pollution, because it does not contaminate and has zero emissions and we use one battery every 5-10 years."

200 batteries !!!?!?!? a day!?!?!? not realistic..
he probably meant: we have reduced the battery use by 200% a day... and have reduced the pollution by  70%.

This would be far more realistic specially as they call it themselves:  "the eco-friendly motorbike"


But if a reputated news agency like reuters writes this article, hundreds of other newspapers or news sites will take it one to one, without even checking.


So i personally think that those guys invented an electric motor bicycle that uses 2 times less energy than an ordinary one.. thats all..
but again.. I could be wrong 

Luc

PS: they won the prize with it.. because it has probably a very low energy consumption...

Agree.
If here be selfrunning bicycle, then in all word say about it.
Here probarly translation errors or not understanding errors, that they students wants to say.
With that small tires and how fast he riding in video, not seems, that this bike, can run 60 km\h. Students probarly say 60 km distance. But I think, that they not meashure that distance, but gues, so in reality it is much smaller.

[MenofFather]

....
Notice that the students said they have gone five months without discharging the battery... 

[/font]
Maybe they only make 5 minutes in every month riding? Need known that distance they run in this five moths?

It seems to be that some sort of dynamo (generator) charges the super caps which is supposed to keep the battery charged.
Normally that wouldn't be self sustaining, so how???

Maybe dinamo with supercaps have eficienty about 200 precents?
