of electricity producer exercise bike




by the Egyptian » 09/01/07, 17:02

Hello everyone
by dint of not finding one ends up asked, so voila
know a city where you talk about a bike that can produce electricity, to power a living room lamp or other.
The ideal would be with a battery for example to spend the evening only with.
to make it even, if a good soul has the plan well detailed, I must say that the level on this forum impresses me and it's not worth telling me anything tricky for the moment.
finally your opinion is valid and possible to implement.
thank you for your answers.

with a good workout, if you are young and healthy, you can expect to produce 100W muscle power continuously for about 1h before being really tired ... so you will have 100Wh in your battery, which will allow you to turn on a 10W LED lamp (a bit dim for a living room !! at the limit, as a bedside lamp, and again) during 10h ... or a small halogen spot of 25W (well for reading) for about 4h .. .

but that is by counting a total return of the chain < bike -> dynamo -> charger -> battery restitution >> of 100% ... utopian. if you reach 40%, it will already be good.
your final autonomy will be 4h reading in your bed with low light or about 1h30 with a halogen spot ...

for an hour of pedaling, it's not great.

at the limit, raise a hundred mice that you feed with the detritus of your kitchen, and plug a mini dynamo to their wheels, you will have more juice.

I know it does not answer your question, sorry if I demotivate you ...
it seems to me too uninteresting energy level produced.

it is feasible, it can quite implement for cheap with the stuff of recovery and in a short time, but it is not worth a solar panel of 1 / 2 m² on the roof ...

Hello pollux
Thank you for your answer .
Apparently the human body to produce energy is not the best.

As Pollux has well explained, the problem is performance.
Besides the friction during the "mechanical" part of the process (pedaling), you have many energy transformations that lead to losses
  • a mechanical energy transformation into electrical energy in the dynamo (or any other type of generator using pedaling as primary energy),
  • an electrical to "chemical" transformation during storage in batteries,
  • a final transformation from "chemical" to electric when pumping the juice in the batteries


In short, if you really want to get into it, go up a gym: you'll have hundreds of gogos who will PAIT to produce your electricity : Mrgreen:

+ 1 for Targol! : Cheesy: : Lol:
how to make money by staying green!
even better: how to make money by making people renewable energy producers!
I just love it!

hello targol
it's an idea to follow : Mrgreen:
and who knows one day.
Joking has, thank you as it is clear, I would not abuse, but given the level of conversations that you would advise you to learn eh we will say the basics of electronics and electric motor to eventually one day be able to build a wind turbine or other things to brew on the conversion of the current etc.

because the on your city is heavy and I must say that it concerns me but I am completely on the street.

to learn a good package on wind, there is a site not bad:

http://www.windpower.org/en/tour/wres/index.htm

afterwards, in terms of amateur construction, there was

http://www.mini-eoles.com
but the site is under construction for the moment ...

Hi, for the average performance in pedaling, we must see that there is braking the wheel with a strap!
for those who need to lose weight, it is a very good solution
for mounting a single dynamo is enough, or an alternator by putting the + on the ex. when starting up. It's still better to charge a battery, than braking with any system

hi the Egyptian

Will tinker 6 months in Africa or mada will teach you more practical things : Lol: by doing long studies.
