This is one of your best! Lots of tech detail included and it’s nice to see Denise getting involved. If you were looking for another project, maybe you could create a DIY e-bike.

I wouldn’t ever call him an a——, I think he is very nice, but I was sort of thinking the same thing about his poor wifey, but she is young and so she seems to enjoy it. Wait a few years.

Hi I think the best way is using an condensator(1F and 35V) and not battery, because usual battery(accumulator) has limited charging cycles and of course usual PB battery is not the best options…

Cool stuff, but solar panels seem like a much easier option.

lol your tv turns of if you stop pedeling

Very kewl demonstration as always. I bet Denise was feeling the burn from this video. Good to see your wife getting involved too. Good for the marriage.

why dont you get on the bike your self instead of barking orders at her. asshole

Enjoy your vids.
Thanks.
I wish your dog the best in doggie heaven.
God Bless,

cool vid.
I remember seeing on tv years ago, a gym that hooked their equipment up similar to this.
The energy efficient light bulbs don’t work with a dimmer, so it’s either off or on. A 25watt or 40 watt bulb would probably work better.
Is there anyway you can use a higher gear, might be easier to peddle.
The fan’s a good way to workout and keep cool.
You could put a sign over your garage that says “free gym” and power your house:)

great info :]
Thank you greenpower

The voltage of the batteries translates almost directly to the RPM of the pedals. The torque the person produces translates to the charging current.
200W at 14V 200/14 = 14A
Charge an ideal 60 AH car battery:
60AH / 14A = 4.3 hours
Assuming 50% about efficiency, it would take 8 hours of working very hard to charge a battery.

You could also drive an air compressor directly from the chain. Compressed air is a better way to do things like power tools.

Wow she’s fit!

Thank you Midnightrider.

Sorry about your dog too:-(
Thank you for the nice words.

The average person can generate about 200-300 watts for a minute or so. If you are in really good shape, you can hold it for 30 minutes to an hour. It is estimated that Lance Armstrong hits 500 watts for 20 minute bursts.
If you consider loss in the generator and charging, This set up is about 100 watts. 10 hours of pedal time equals 1KWH.
I do think the load is nearly maxed out when charging. Denise rides daily on a stationary bike. Two of these motor/generators may be a possibility. 200+watt

If everyones TV and Computers where hooked to that we would be a nation of fit people.

you need a flywheel
January 11th, 2009 at 1:54 pm
Charging a little battery like that is one thing. But would it be more difficult to impossible to pedal if your were trying to charge a whole bank of batteries in say an off grid home solar/wind power system?
Or would the resistance be the same, but the time you need to pedal for be greater?

I lost a dog named Sable as well, sorry for your loss.
January 11th, 2009 at 1:54 pm
I was thinking a flywheel would do the trick too.
January 11th, 2009 at 1:54 pm
hey guys I like the idea for using this for and exercise bike…. I would recommend you guys attach a flywheel to your system, this will help reduce the inconsistent rotation speed caused by the natural pedaling motion of a human. This will also help reduce the sudden jolt felt by the rider when a load engages the system. (Id say 30-90lb based on set up) all of this will contribute to higher quality power output.

great video. my condolences for your puppy
January 11th, 2009 at 1:54 pm
Your videos are always so informative! I love that you show us the Amps, rpm’s, and tech. info that is always helpfull to my Dreams. I’m sure you know what I mean. From the only Cuban in Tennessee Great Job!!!

Nice idea but I don’t like to pedel that much try a bigger brushless motor and see where you go from there also you could have used a freqency generator and got more effiencies out of the loaded motor because you would see a half current draw insted of the whole current draw. Nice idea to see.
