R-Walker Selfsustaining Free Energy bike from Mexico
« on: May 11, 2015, 08:29:11 PM »
Hi All,
there are 2 young Mexican inventors, Victor Garcia, age 17 and Raul Grajales,
who has built and shown a selfsustaining electric motorbike.

It is started by a conventional 12 Volts Lead Acid battery and
if the back wheel goes faster than 2000 RPM the whole bike gets selfsufficient and propells itsself
via some kind of recharging process.
They also use 2 big 1.5 Farad Supercapacitors for the recharge storage and probably
these supercaps also recharge then the battery.

Here is the text Reuters has published about this invention:

Mexican students invent eco-friendly motorbike

What if you could harvest the energy of a moving vehicle to continue to power it ?

That is the question asked by students of this technical high
school college in Oaxaca, Mexico, one year ago.

It resulted in this prototype motorcycle called R-Walker created by 17-year-old Victor Garcia.

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.”

Garcia calls the process “auto-sustainability.”

It’s based on the principle of converting energy through speed and distance travelled; the engine becomes self-sustaining,
generating more than 2,000 revolutions per minute.

A battery is used to spark ignition, and afterwards without using any combustion the vehicle can carry up to 110 kilograms
and travel at more than 60 kilometers per hour.

Co-designer Raul Grajales said R-Walker could bring huge savings for motorcycle users, as well as the environment.

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.”

They built the eco-friendly motorbike from recycled materials, bringing its final price tag to around $200 – a comparatively small sum when considering its potential benefits.

Here is the video from it:

Please share on Facebook and give a thumbs up,so this
technology is being spreaded and will be known much more.

Many thanks.

clashed with teams of Turkey, Brazil, Italy, Argentina, Belgium, China and Slovakia, among others


  Students of the College of Bachelors of the State of Oaxaca (Cobao) represented Mexico in the International Robotics Tournament Exporecerca, held in Barcelona, ​​Spain, where they obtained the gold medal with the prototype "The Caminate" which is a self-sustaining scooter it does not require fuel to operate.

  Young Victor Ricardo Matias Garcia and Raul Grajales Guzman, respectively and coursing the sixth semester on campus Pueblo Nuevo, arrived at the International Science Fair Exporecerca with the R-Walker, a kind of compact scooter capable of transporting a person virtually permanently, because it has a self-sustaining engine that converts mechanical energy into electricity to feed themselves.

  This prototype won a Gold Medal in the innovative project, which gave the jury the event, and a further ballot held among those attending the exhibition category.

  Oaxacans who represented Mexico in Europe involving more than 200 students from 15 countries, who submitted 116 projects in science and technology.

  "We design a mobility system that does not pollute, it does not require fuel, ie it was self-sustaining and that would meet an important need mainly in rural areas of our state: transport," say the young graduates.

  Smiling, Victor and Raul explained that worked for a year in the planning, design, construction and testing of the prototype to refine the details of its operation.

  For the project used the structure cut from a bicycle, he adapted resistant tire to road, put an engine two thousand 700 rpm, a capacitor and dynamo that act as generator, buffer and alternator power and a battery that only used for spark ignition.

  "This vehicle keeps moving and generates its own energy," they said.

  The R-Walker resists up to 110 kilograms and caused a sensation in the Multimedia competition.  It cost about three thousand dollars, but if done in series that price would drop considerably, indicated Cobao youth, we are advised by Professor Alejandro Villavicencio Arenaza.

  Students have the research protocol;  plans and photographs of the design and construction as well as a thorough evaluation of the project, presented at the Magna Science Fair where teams of Turkey, Brazil, Italy, Argentina, Belgium, China and Slovakia participated, among others.   Oaxaca, April 15, 2015

I think the MSN piece was really bad.  It looks like he is just using regenerative braking to recharge.  The big black thing in the middle on closer inspection looks like a sealed lead acid battery.  The big super caps buffer the regeneration current.

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  :P

Luc

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

That sounds very plausible.
I take issue with using "two times less" instead of 'half'.

"It’s based on the principle of converting energy through speed and distance travelled; the engine becomes self-sustaining,
generating more than 2,000 revolutions per minute."

I would like to know what that principle is. That is more than a little vague.
If these students and their teacher had a bike that could actually power itself,
they would have done a lot more than win a robotics competition. We would be
hearing about this everywhere in the news I think. I agree that it seems much more likely
that they just have implemented a method to improve efficiency quite a bit. This news story definitely
needs clarification from someone with a science or technology background, so the actual facts can get sorted out. :)

Actually, in Stefans post it says, the engine is running at 2000rpm, not the wheels. ::)

I have 3 electric bikes. 2 are 36v and 1 is 48v, 12ah sla batteries, and one bike uses 30 NIMH D cells. They all 3 do near 20mpc. (miles per charge)  I would like to see the vehicle or info that you claim a 12v batt, such as the one we see in the pics, which looks to be a 7ah, possibly a 10ah battery, can run a bike at 60kmh for as long as they are running their bike. ;) ::) ;D That will impress me. ;)

There are electric skateboards with much smaller wheels than shown on this bike that can do 40mph.  ;) So that is a bad argument. ;)

sorry if there was a misunderstanding..
i did not claim it is a 12 volts battery..
I only assume it is a 12 volts battery by the pic i saw.. nothing else.
and as for the 60 km , I only assume he could have meant a 60km radius.. NOT that he did actually mean it..
because if you see that bike Icannot imagine it running at 60km per hour as it is stated in the reuters news item... specially if you see the inventors in the video..  and they would have probably shown a demo if it were really that fast...

I was just trying to explain how misunderstandings can occur by translation errors.. and if a "famous" news agency like reuters posts something like that , nobody double checks...

thats all...

In the spanish/english translation from the Oaxaca Government is another fault :
http://www.miconversor.com/3000-pesos-mexicanos-a-dolares-americanos
not 3000 US Dollars !
But the right price estimation we can took from Raul Grajales Guzman answer at the first post.

Found another story in Spanish on this, and they also seem to
be implying that it is a self running bike:

Original Spanish:
http://asociacionculturalmexicanocatalana.blogspot.ca/2015/03/proyectos-mexicanos-se-expusieron-en-el.html

Google English translation of the relevant part:
Quote
"R-Walker (Oaxaca, Oaxaca) Manufactured Cobao students (School of Bachelors of the State of Oaxaca), the R-Walker, is a prototype of
alternative and renewable energies rural and urban use.  Do not use fossil fuels or recharge batteries, it is one of the first worldwide to be self-sustaining?
It's kind of compact bike capable of transporting a person almost permanently, as it has a self-sustaining electric motor and therefore does not require any
fuel to operate.  R-Walker was created by Victor Ricardo Matias Garcia and Raul Grajales Guzman."

It seems unlikely that it would really be self sustaining and not have caused a major
sensation on all major news networks around the world. Something doesn't seem to add up.  ???
How could a reporter report on a story in which they state that a machine is self sustaining, and not
ask all kinds of questions about how it is supposed to work and how they confirmed that it is self sustaining. 
It's like reporting on a story where you say that so and so invented a machine that can transport
people anywhere in the world by dematerializing them and rematerializing them somewhere else, and not asking
any follow up questions. Duh! ;) Someone here with a technical background who can speak Spanish should contact
the teacher at that school involved in the project and get clarification on how the bike is supposed to work according to
the teacher.

The set-up looks like a basic regenerative braking arrangement.  That's a good thing to have but not new.  Neither is using super caps to buffer the electrochemical battery.  If the thing goes down a 1km 3% grade, it is a safe bet that after coming back up that grade the battery will be more depleted than at the start.

Here's another news story on the R-Walker.
The students definitely appear to be saying that they think the bike is self sustaining.
It is just very vague about how this is supposed to work exactly. This story has a little bit more
detail, but not much:

Original Spanish:
http://www.noticiasnet.mx/portal/oaxaca/general/educativas/274215-neuropower-del-cobao

Google English Translation:
Quote
Have just 17, but their names are entered in the registers: they are inventors.  This is Raul Grajales Guzman and Victor Ricardo Matias Garcia, students in sixth semester of the College of Bachelors of Oaxaca (Cobao) 01 Pueblo Nuevo, who using the principle "the matter is not created nor destroyed, only transformed", designed and They produced the R-Walker, an autonomous bicycle without pedals capable of generating its own energy of motion.

 This prototype won the gold medal awarded by the jury of the International Robotics Tournament held in Barcelona, ​​Spain, in the category of innovative project

 The invention was born a year ago from a set of ideas and trials Club Cobao Multimedia and Robotics, currently composed of 32 students.  The starting point was European prototypes of urban mobility.  The challenge was to create one that does not use batteries and is capable of driving on the streets of Oaxaca considering their difficulties.

 "We also saw the problem that there are young people who walk hours to reach their schools, in Oaxaca people walking hours in the mountains to get to take your truck and then plan to make a prototype that could help these people, however we find the first problem: how are you going to give a person a system of mobility if you tell them they have to buy gas or have to recharge a battery in eight hours, "Ricardo explains.

 From the above approach Raul and Ricardo, under the guidance of Professor Alejandro Villavicencio Arenaza, managed to develop a prototype using renewable energy to generate own speed.  "We have five months without discharging the battery, this means that the prototype works," says the student.

 The R-Walker has a suspension unpressurized oil-and-only tires with asphalt type.  "We worked mainly on design dynamo used on bicycles for the lighthouse. It is used to feed the stored magnetic fields in the capacitor of the left side and from there the battery is recharged and the battery moves to the engine and the engine start the cycle. The loss is 0.3 volts between the generation and use, " explained broadly.

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

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