Just throwing some more scrap together. This time we are going for a gravity generator build.
Lets see what happens.

Hi TM.

Are the plastic insides exclusive to Australia? Everything we have here is made from steel. They also use motors here unlike your setup.

Hi TM

Our washers don,t look like that one either. You better get more of them and EXPORT. LOL

Most of our washers have the normal induction motors,but these smart drive motors are by far the most efficient.They are avalable in america,but not england. Not sure about over your way Dave.
And yes,all that i know of are plastic,except the drum-which is S/S

I have just started advertising for these very machine's,and will also be visiting the local washing machine repair shop.
Once i have enough of them,i would be happy to pass them around to those that want one.
I guess we would have to look into shipping cost.
I will see how much they weigh,and post here tomorrow.
These would be hard to beat for a wind generator,as they produce a lot of current at very low RPM.

I have decided on a motorcycle gearbox for the gravity gen.

That engine brings back memories :)
I used to do repairs/upgrades on my bench over 20 years ago.
Looking forward to seeing this progress.

Well it's on hold until the wether gets better(as it's raining cats and dogs here),as i can no longer fit it into the workshop-as it has the 6 meter pole standing virticle on it now.

Has this project gone any further TM? I'm playing with something similar, but want to see if it can be done with no gearbox. or as little gearbox losses as possible.

I want to make a generator that has high resistance to torque. So hard to turn and produces 3-12v with some decent current at very low rpm. If I had a front loader motor like yours I'd use that, Although I cant help but think a custom made generator would be better.

I know stuff all about winding motors. Thought someone in here may be able to help a bit. I'm thinking low resistance coils, so few turns of thick wire, and lots of coils combined with strong magnets would be the go?

Does anyone have any suggestions? I'm currently playing with a very large stepper. Getting 30secs run time dropping a plastic juice bottle from the top of my fridge (about 5 feet)with about 900ml of water in it. One interesting thing I have noted, is the greater the load, the slower the weight falls. which is good. add more LED's and get more light and longer run time. The downside is the slower the fall, the more inclined it is to produce flickering light. This can be fixed with more weight, but then the run time gets shorter again. I think I will have to compromise with at least one stage of gearing. with as high a ratio as possible.
My thinking is make a generator that goes slower as more load is added. so more lights equal greater run time. I do realize this will mean more weight needed, but thats ok. I'm aiming in the 5kg/12lb range. So far I'm under 1kg/2lb. Thinking 18" bike wheel for the pulley, so the generator can have about 20-30 foot pound of torque applied to make it turn, and should not turn at all with less than 10 foot pound applied.With a max rpm of about 2-5 turns a minute. Is it doable?

It's hard to make anything foolproof, because fools are so damn ingenious.

Hey MongrelShark,
TM is hard to catch on here now ... You could try his youtube IM for a quicker response ... Or his email .

Me I'm trying to visualize your project to grasp what your plan is ... Do you have a drawing or anything to help ?
