Human Power Generator Series
Human Power Generator

Use pedal power to generate electricity. The Human Power Generator is user friendly, portable and available whenever you have the need for it. The power output is directly proportional to the effort put into it. The Human Power Generator can be a valuable tool in teaching an appreciation of the physical energy required to produce the electricity we tend to take for granted.

The Human Power Generator is primarily designed to charge a 12Volt, deep cycle battery or to contribute to a 12Volt system. It can also provide DC direct power.

AC appliances can be used with the Human Power Generator by using a DC-AC inverter connected to a battery for stability (see our Portable Power Pack). It is also possible to directly power certain DC powered equipment such as a low power water pump without using a battery. Appliances such as a DC television, light or radio may also be used. However, with this application, a voltage regulator may be required and keep in mind that the electrical current delivered, follows the same rhythym of your pedaling - which is not constant.

The amount of electrical power that can be generated by the Human Power Generator is determined by the energy available to turn the crank . The stronger the user, the more electrical power can be produced. Typical output in watts with the Human Power Generator is about 60 Watts or 35 Watts with handcranks.

The Human Power Generator consists of a heavy, powdercoated steel frame holding a bicycle-like crank, with a step-up chain drive (6.5:1) attached to a permanent magnet DC generator (stock # 443541). Each Human Power Generator comes with standard foot pedals. We also manufacture optional cushioned hand cranks can be attached to the two crank arms for an additional $35.00.

Applications:

* Emergency power generation and battery charging - land and marine.
* Exercise systems that do useful work generating power while exercising.
* Measurement of human power and endurance.
* Remote or off-grid power for water pumps and small appliances.
* Independent radio or radiotelephone systems; emergency communications.
* Classroom projects and educational exhibits to demonstrate the amount of effort required to generate electrical power.

If the Human Power Generator is purchased on its own without a Power Pack, it automatically comes with a heavy duty diode protected connecting cable. You can choose the kind of wire termination that suits your application. The most universal cable uses plier- style clips to attach directly to the battery posts.

The diode is built into a small in-line aluminium box and prevents reverse current from traveling back from the battery to the generator.

Something more like this with the bike wheel acting as a flywheel but without the power pack of course.

I see what you're saying, but my parts are different. Again, I'm going to hook up the gen to the motor and start pedaling and see what RPM I need to hit to get the motor moving and go from there. I know I can get it to work, just a matter of tinkering. :)

Sounds like fun, though I'll have to read the thread again. It didn't quite make sense the last time I read it.

How about this hypothetical:
4 people pedal a huge reduction gear train which bends back a semitrailer rear leaf spring set. Once the leaf spring is tensioned, it's locked and another set is tensioned up.
Once the mechanical energy is stored in the springs, the gear train is reversed with a slightly lower ratio and connected to the springs.
The output of the geartrain drives bicycle wheels via chain and sprocket.
Releasing the springs turns the gears and propels the vehicle.

No motor, no electricity, no gasoline, no steam or fire, just stored mechanical energy provided by human operators.

Simple.

No.

The MV can move without being activley powered by a human (on level ground).

symantics. It's kinetic. It's still not a motor.

Tell ya what, make it and see. I'd love to check that out. If it can move more then 10 feet, cool. A mile, hot. Which would be about across the middle of the playa, once.

Same as we did last year, but different approach. Its just energy banked via a mechanical battery. We needed no MV license. If left to run on its own banked energy (i.e. you quite pumping the flywheel and let it coast), the contraption would roll about 30-40 feet at most before stopping. If allowed to start on its own with the flywheel spinning, you'd get 25 feet or so.

That makes me think of heading across open playa pumping that flywheel. I guess we'd put about 5 miles or more on the ol' girl by the time the week was over. Almost a mile across... 2 mph... took us a while to make that trek because we'd stop now and again to catch our breath.

I forgot to log my milage last year. Emptied both tanks of gas tho. And added a little more. With an average of 300 miles on a fillup, I wonder if we did that much? We were cruising every day, all day and night.

I'm building something very similar to a peddled car, however, I do not have welding experience or immediate access to a welder (due to cost).

I've decided to go with PVC for building the frame. I'm a virgin this year so I'm not 100% sure it will hold up. Has anyone done this before?

I'm building it using some pretty thick stock and am using shorter pieces with connectors to limit the natural "flex" that comes with using PVC.

Thanks!

Bring extra PVC parts and PVC glue.

Everything breaks at least once on the playa!

I used some slipjointed pvc last year.
Held up, but wasn't on a vehicle.

I saw a big dome built of cheap pvc with no rigid joints.
It all flexed like crazy but distributed stress and never broke.
Very labor intensive to put up though.

Thanks for the input :)

The vehicle will be made entirely out of PVC minus the wheels, steering, drive system, and the seats.

Now the trick is getting two independent sets of pedals added where either person (or both) can make it go.

Also, look at the idea of adding screws to your joints. The glue can bust. Screws give a joint a second failsafe.

Let me confirm that you DO want individual freewheels for the riders. Do NOT fall for the temptation to hook the two pedal sets together because it is easier. Only experienced tandem bike riders have any hope of coordinating their feet that perfectly.

An other thing is to NOT drive two wheels on one axle without some means of letting those wheels roll at different speeds in turns. You can use a lawn tractor type differensial, but I prefer to simply let each rider drive one wheel.

Yes, if the vehicle has only two wheels -- side by side. Did you see the one we had in my camp last year?

But if the vehicle has more than two wheels, the effect is minor, and can be used to advantage when you need to turn sharply. We do it all the time with that thing in my avatar.

A lot of these are hard to describe.
This one had rear weight bias like a rail and had NO front steering.
You had to lift the front to steer.
Also required two drivers.

If the flywheel can store a significant amount of energy, we'd consider a "motor" and thus it would need a license.

And the basic rule is, if it has a motor and a seat or three or more wheels and motor it needs a license. So small go-peds are ok. And ANY sort of motorized bicycle is NOT.
