Great vid! I subbed.
it is great video, its so great to find some who are really interested in showing how to do it and explaining each and every bit keep it up
What you have to do is link many car batteries up in sync and in parallel to get your voltage and amperage right. You can then use a car battery trickle charger to charge them all and the converter to make it ac power. 10 to 20 car batteries hooked up right could provide plenty of power with minimal charging times.
A great lesson for us all but she is not a reliable consistent source of power.
good stuff you got here, keep it up
im so in love with denise…
The best application for this device(in my opinion) would be for watching TV or surfing the web. If you had to ride to make them work you would watch as much and would get a lot of exercise at the same time. Before you get mad about comfort think recumbent/lazyboy style bike.
This could be a great idea to trick my wife into getting a little more exercise.
Thanks, bud!
This is by far my favorite GPS vid…
tjgame2 dont be lame just cos you cant get a woman.
5 star for Denise
maby in the end of this experiment this guy can make a light running on his bike….. like they had in the 70´s…..woooow.
Great vid as always … where do you get the time?
Sounds like Sable had a long and good life and is smiling down at you right now.
I would like to try some of these experiments, but the wife won’t stay on the bike … can Denise come over for a few days?
i like your wife
Well I learned about a feedback diode, which is necessary to stop “back-charging”. Enjoyable and informative. Looking forward to the next one!
Yes to the flywheel and the capacitor both. It doesn’t take much flywheel to store the same energy as a huge capacitor.
Great as always! Always like finding a new clip from you guys.
Sorry to hear about your woofer though, Sable was the name?
Peace
I think the goal is to take what we have and use it as Efficient as possible by adding to it what is needed. Sure you can make a really efficient setup if you change the generator and figure the optimum gearing. In that case it would be better to start off with an AC generator instead. Adding a Flywheel would be easy enough and you can add in a Capacitor as well. Even adding a battery as Dan stated in the video would work and would serve to protect the equipement being used.
Get on the bike, Dan! You’re working Denise too much, lol!
No computer. COMMUTER. You know getting to work… LOL (My eyes play mad-libs on me all the time too!) Thanks.
Use a higher voltage generator or a bigger gear ratio. Denise’s optimum pedaling speed should be determined and the voltage made just a bit more than needed at that point.
DC-DC converters that both boost and buck are less efficient than ones that only buck. Since you don’t have to worry about polarity, I’d use a Cuk converter if I had to both boost and buck. For bucking, I would prefer to switch in the minus side.
At an output voltage of about 12V, a Schottky diode as the catch diode.
The reason I would allow the voltage to drop as far as 12v is to allow the motor to turn at a slower RPM. That way Denise can peddle longer. The load will be somewhat consistent and should not max out the watt rating on the motor. It takes more human energy to turn the motor faster and you will still be producing the same amount of energy. So what needs to be considered is to maximize the endurance of the human. A flywheel would help although it would put more load on the human energy.
You don’t want to throw away any of the energy. The Zener idea is a very bad one because a 300W zener is a great big expensive thing. A flywheel with a large capacitor as short term storage would be a good start. A DC-DC converter as a regulator would be nice to keep the voltage more constant for the load.
The energy in the capacitor is:
E = (1/2) * V^2 * C
This means that a really big capacitor would be needed if you didn’t use the flywheel.
