1000 watt human power generator build

[Cameron sydenham]

Good afternoon. I am hoping for some guidance on a homemade build.
Goal, human or 2-3 humans powering a microwave.
I am trying to create a device that would use humans to turn a generator to produce enough energy to run a microwave @1000 watts.

I am thinking I need a generator that produces @1000 watts @1000 rpm. I have seemed to land on a wind generator, windy nation and hydrogen appliances carry a few. What and how do I go from the generator to a "plug" for the microwave is the question?
I can build the contraption to turn the generator, what I am confused is
1- should I buy a 3 phase ac generator
or
2- a generator that is dc output
3- whichever I use, what else do I need? and how to connect it all?
generator-rectifier-inverter plug?
any guidance is great here.

Hi Cameron,

I really think that 1,000 watts is a pretty big ball park to play in. I have a Windstream DC generator attached to an indoor bicycle trainer

http://windstreampower.com/

and I crank it while I'm watching a DVD to do my "daily grind". I can quite comfortably churn out 100-110 watts (at 12 volts) for about half an hour, and my heart rate sits comfortably at 110 bpm +/-. I can get up to about 130 watts but only for a couple of minutes before the heart rate gets up to 125-130 bpm. On my road bike I can max out at 137 bpm going up a moderate incline.

The DVDs I watch are usually recordings I've made of bicycle races such as Le Tour de France or Paris-Roubaix. Over the last couple of years the racers have been fitted with metering which show power and heart rate. Every few minutes the commentators will let the viewers know the figures and on a "flat" stage it's not uncommon for riders to be pushing out 250 watts, with heart rates at 165+ bpm.

In a final sprint for the finish some of the riders can generate over 1,000 watts, but that's over about 2-300 metres. I don't know what their heart rates are. (One track cyclist was measured at 2,000 watts over a very short sprint.)

Admittedly I'm over 65 years of age, but on the other hand I've been cycling since 1972.

This might be of interest.

10 cyclists generated 1.2 kW to run a supercomputer.

And this British TV show has 80 cyclists pedalling generators to run a single household over about 8 hours.

Make sure you visit your doctor to have your heart checked. :blink1::D

Hi, you will need a power conversion circuit to deal with the copper loss like a MPPT circuit.

If you can pump water it will generate electricity. Use a one way bearing with a rigid pendulum to drive a PMA.

Had a bit of a chuckle at the Swing Gen video. Seems short of a few important pieces of information. Like exactly how physically big will a 1,000 watt machine be. I can scarcely see one sitting in the living room so one could watch TV or do anything other than try to generate power.

The Windstream is extremely compact and takes up very little room, and can be operated while lying back.

Then how much power does the operator have to put in to get out any useful amount of power. I've indicated my heart rate which is a rough and ready guide.

As the Swing Gen seems to be oscillating at two stages of the cycle NO power will be generated (power would be generated in a sine wave if I understand the explanation). So how long would it take to generate a useful amount of power. The Wind Stream can generate 30 watt/hours of power in about half an hour.

So many questions, so few meaningful answers.

OP, here are some things to consider. Hook up your generator to a bicycle.


See what peak output you get when pedaling. How long can you maintain that peak output?
Now look at average output over 10 minutes. How many watts are output, on average, over this time?
How will you measure the power output? Do you have a watt meter? Like Kill-a-watt or the equivalent?
You can use your microwave at 80% power for almost everything, that's what I do. If I cook anything over 80% it tends to be overdone on the edges and undercooked in the middle. 80% is a great power level, and I use just 20% less time than the box says and it usually comes out perfect. If you have a 1000w microwave using power at 80% you are only using 800 watts.

It looks like this thread is getting old, but I was actually looking into these types of
generators myself. I like what I see on the Windstream site, but I wanted to see if anyone
had experience with either of the two listed below. They aren't claiming a 1000 watts or
anything too out there.

I've been experimenting with and researching various claims of OU devices for the past
seven years, and I'm just looking to see what can be harnessed from a little bit of effort.

Hi, the two stage oscillator looks interesting. I am working on a multi beam version.
