   if you left your car lights on all night and flattened the battery, how long would you need to pedal for to get suffiicent power into the battery to start the car again i wonder ?

   So a battery in line with the system would condition the volts and watts. Great stuff.

   Im A new fan of the site and i am amazed. I have always loved enegry and even made some generators and water pressure powered motors to power a sob pump. I am getting so many new ideas, Thank you both.

   Pretty good demonstration that pedal powered electrical generation is very impractical. Batteries need both power and time to charge. I can’t see someone pedaling for a couple hours to charge even a low power battery, like a cell phone. On the other hand, direct bicycle power for short term use for some device, like my sewing machine, can be very practical.

   So im looking for overall motor efficiency, internal gear box and reasonable attainable rpm? This is the key attributes to your specific setup?

   Feel free to remove these comments.

   Car alternators unmodified are a bad choice. The RPMs needed are too high and the rotor needs to be powered (exciter) alternators use electromagnetic field so you need about 65 watts of power to gain full power. Fully charged exciters are very difficult to turn. Car alternators spin 2x the engine RPM so 5k +
   Rear wheel pulley slips when a similar load is placed. I have seen on planet green an guy using drill motors with the belt setup. He is producing 15 W this is 100W+

   If you use a standard vehicle alternator, wouldnt this eliminate the need for a charge controller? Seeing as an alternator usually peaks voltage at 14.6v?

   Also, would leaving the rear wheel on and using a standard serpentine belt rapped around the rear wheel groove(tire and tube removed) and alternator pulley be the better solution, providing you with more gear options?

    i done the same thing hooking up a scooter motor 100 watt 24 volt with a bike and belt and noticed that you cant just use the dc to ac inverter by itself to power anything i almost cooked it . inverter must be hooked up with the batt in order to power anything or to charge the batt but yea works well

    I don’t know why they say it’s green, when it isnt! Humans/animals are generators of carbon dioxide. The harder you work the more you produce. Hydroelectric dams, solar panels, wind turbines are more green than anything animal or human powered!

    the alternator used in cars is the most efficiant.

    this is a great video one of the best iv seen from you and on youtube. great work. lol your wife must of been tired after
    that. but a have a ? if you were to use say the same motor
    for a generator and another to drive the bike would that complete the loop. so it would drive and generate at the same
    time. could you do a project on that please. if not great work .
    2 thumbs up. thanks!!!

    Where could I find 10 girls as fit as Denice to drop over and pedal 10 bikes for 3 minutes when ever I need 2 slices of toast.

    can you use AC and DC motors as a generator? does it matter? does one work better than the other?

    man i love these videos! and the comments can be almost as educational as the video lol

    Is their anyway i gnerate electricity from a home made generator (rotating magnets inside a ring of coiled copper wire) and connect it to something that stores that electricity, or uses the electricity to charge a battery, or to run another motor? any of these
    (and what is DC and why cant AC charge a battery?)

    say i wanted to but a steam engine to a generator how would i wire it to my house so i could still run off city power but i wanted to cut down on my power bill
