Great project again, congratulations! I made the Power Pedal Generator and I love it. I train almost every day and charge a powerbank that I build, then I use it at home with mobile phones, computers, tablets ...
This is AWESOME! Just what I was looking for. The next thing I was thinking of was a dynamo setup for doing deadlifts. Basically could be very similar to this one, with some tweaks, and probably not with a flywheel-type of construct... but I will think about this.
This seems like a better way of getting some electric power for normal people than just a bicycle as this is a full body workout, not just legs, thanks for sharing the project it looks pretty interesting. EDIT: Sorry, I forgot to ask, how would you compare your capacity to put power to a battery from this rowing generator against a static bicycle, are you capable of better power output with this machine?
Actually for me, not an avid rower, I can hold higher watts on the bike generated than the rower, but I think if I had more time on the rower I could make the same or higher with the rower.
The flywheel does resist spinning until you get it going, then like you are leading to, the resistance comes from watts needed to charge or power things. A TV might be 30-250 watts depending on a number of factors. Mobile phones can take 5-20+ watts charging, laptop computers 30-150 watts. Just find the right amount of watts to make for a good workout! On the rower, I’m happy between 80-150 watts of resistance.
After putting in some bigger ultra capacitors, I was able to get up to around 250 watts going into the battery bank. Granted, this fifty something non-rower couldn’t maintain that pace for long… I’m happy around 100-150 watts.
@@GenesGreenMachine Thanks. My general masterplan would be to store the power and then send it to an electric heater (6 Kw). I wonder how much I'd have to row to run the heater for two hours. Any idea?
Let’s say you can maintain 200 watts steady. Every hour of rowing will produce 200 watt hours. To get 6Kw for 1 hour will take 30 hours of rowing, 2 hours of heating will require 60 hours of rowing. This experience will give you a real appreciation for the electrical grid.

Hi there bro... just found ur channel, how are the PVC handles holding up? Im a little bit worried about the plastic, it didnt wear out over time? How they holding up?
This is awesome! Electrical applications are not my specialty, so please, bear with me.. How come no alternator to battery to inverter setup? Is this better?
Initially when starting, getting the wheel moving does take a little energy, but once up to speed, it’s much like it would be on the water, maintaining momentum and actually helping the rower keep a steady speed.
Nice build dood and thanks for sharing! Hoping you can help me? I want to use multiple sources to charge a battery bank. Wind, solar and rowing machine, mppt charge controller, lead acid leisure batteries and a range of loads. The controllers documentation does not say anything about multiple sources, do you know how? Cheers. Tanc
Hi sir!, what's your basis why did you used 56 pounds, is there any significant reasons behind that, this is for research purpose, hope you will reply soon. Thanks!
No significance. The flywheel was custom cut to fit the e-bike motor and to fit within a spin bike frame, the weight just needed to be between 25 and 60 lbs to be effective. The 0.5 inch steel was what was available for reasonable cost. I had 3 of them water jet cut for $210 US dollars.
Yes indeed! I’ve made a 3 phase bridge rectifier out of Schottky diodes amzn.to/3fBY0yD for higher efficiency, but most off the shelf rectifiers will work, like this one: amzn.to/3RzDtYy If you can find a wind 3 phase grid tie inverter, that will work too!
Banana conectors :D Sorry i know nothing about electricity, is the energy coming from the disc rotating against the engine? instead of the engine propelling a wheel, a wheel propells the engine and... current comes out of it?
Wasn't expecting to see the TV actually working with only the power supplied from the rower.

That’s awesome, I really enjoy hearing stories like yours - it motivates me to continue my blog, and to continue to innovate. Thank you!

Deadlifts are the best human expulsion of energy - but how is that different from a row machine?

I respect so much you and your acomplishment
What exactly supplies the resistance? Is it purely the weight of the flywheel or is there also a drag effect when using it to charge something?

I’m looking to sell this if anyone is interested: www.ebay.com/itm/185829670222
WHAT A COOL IDEA!!!!
Thanks for sharing.
Glad you liked it!
Genius 💚💪👍
Looks neat. Thinking of building one for myself but in EU with 220v output and saving it into a battery. How much power did you get out of it?

Cuantos grados de inclinación tienen los soportes dela rueda?
30 degrees inclination for the supports. Angle cuts are 30 or 60 degrees.

Great video! Looks like you website id down. Do you have the detailed steps published somewhere else?
Thank you! You can find steps here: www.instructables.com/OpenErg-Based-Erg-Rower-Generator/?amp_page=true
That is fantastic!
Excelente idea!.
Where can I find the dinensions of the wooden parts? Jim Flood‘s Website seems to be offline.

Hi there bro... just found ur channel, how are the PVC handles holding up? Im a little bit worried about the plastic, it didnt wear out over time? How they holding up?
I didn’t use PVC, the handle is made out of an oak dowel, 1.25 inch if memory serves
Очумелые ручки👍👍👍👏
This is great, what was the angular velocity of the flywheel?
Ha! No idea. I can get RPM/speed fairly easily though.
This is awesome! Electrical applications are not my specialty, so please, bear with me..
How come no alternator to battery to inverter setup? Is this better?
Just my attempt at building a rower generator, I’m sure there are other ways to go about it.
Niiiiiiiiiiiiiiiiiice!!!
Footrests should not be moving! this makes unnatural movement.
I’ve added a rod of All Thread through the foot rests, that way they can be locked in place, or be movable if desired.
Buenas tardes me parece linda la máquina hola lo único que cambiaría serían los hincapié porque no se hace la fuerza
great work. one point though. Doesn't the wheel absorb too much of the rowers energy ?
Initially when starting, getting the wheel moving does take a little energy, but once up to speed, it’s much like it would be on the water, maintaining momentum and actually helping the rower keep a steady speed.

Hi Tanc, I haven’t done what you are trying, but seems something like this charge controller would be a good choice:
amzn.to/46HL9Rx
This is great!
Great job. I will try to use a car alternator and a battery.

Welldone !
Would a wind turbine charge controller work in place of the setup you have here? I believe they take 3 phase power and turn it into 12v.
Yes indeed! I’ve made a 3 phase bridge rectifier out of Schottky diodes amzn.to/3fBY0yD for higher efficiency, but most off the shelf rectifiers will work, like this one: amzn.to/3RzDtYy

Hello I would like to make this as a washing machine, what do you think I should modifie ?
Interesting idea, but I have no clue
how many rpm in 1 stroke, tia
It depends on how hard you pull! Anywhere from 50 to 100 RPM, give it take.
Excellent video
Thank you!
Banana conectors :D Sorry i know nothing about electricity, is the energy coming from the disc rotating against the engine? instead of the engine propelling a wheel, a wheel propells the engine and... current comes out of it?
That is correct! Electric motors when spun, create electricity. Here we are capturing that electricity and charging our phones, powering TVs, etc.
