Worm gears are great for high torque, but they are also high friction if not using the right materials or proper and constant lubrication. They will eventually wear down both surfaces in contact, but are normally easy to replace (unless you have a bad design, which is not the case here due to efficient simplicity.) Now I'm thinking next level (much more engineering required): multiple clutches, raising one weight after the other in sequence and same when letting go of the weights.

The conversion of potential energy to kinetic and electrical energy is far less efficient with pumped hydro than with a static weight directly driving a generator. With pumped hydro a significant portion of the kinetic energy simply bypasses the generator as the water continues to flow through. With a static weight directly driving the generator, nearly 100% of the kinetic energy (minus that which is lost to friction [thermal] and vibration [acoustic]) is input to the generator. That difference noted, you are correct that a massive weight / height would be required to power an average household, but just as it’s best to have multiple streams of income, it’s also best to exploit multiple available energy sources rather than trying to generate all required power from one source. For me it’s oil, biogas, geothermal, air to water heat pump, solar PV, solar thermal, and wind, all contributing to the whole of our energy needs and providing the excess to the Finnish grid at the same wholesale rate the big power plants receive.

If it worked that way I might just as well haul them up myself.

Would it be viable to design wind turbine that can create a self-sustained central vortex . Using a pressure & temp variation with focused sun light(like magnifying glass) that heats a small dia. center point at the bottom of wind turbine. This updraft of hot air combined with the colder ambient air already spinning your current wind turbine. May spark a self-sustained central air vortex that creates more rotational energy when sun light is available to focus. There is a lot of knowledge I'm not familiar with. But sometimes unconstrained ideas can spark others. Hope mine does.

Too bad you most likely don't have a Gravely two wheel tractor handy or a 400 series ( excluding a 408 ) 4 wheel tractor. Both of them disprove the idea that a worm gear arrangement won't drive from the worm wheel end. The two wheel versions were available with three different worm gears and matching worm wheels. Ratios were changed by the number of leads that the set had on the worm. L models and most of the Commercial and Professional models used an 8 lead gear. These were the fastest tractors and also the easiest to roll. Next were the LI models and the 400s which used the 6 lead worms. Very few of the 6 leads were used in the Commercial or Professional lines. Slowest of them were the LS models with the 4 lead worm. You know when you are dealing with one of them as they will barely roll when the engine is not driving them. Gravely also used dog clutches in them. The PTO output is controlled by one. On tractors where the had 8 speeds instead of just 4, there also was a double ended dog on the axle. Knowing how to operate that dog well, also allowed you to disconnect the axle from the worm wheel if you centered the dog between the fixed one and the one on the worm wheel. There was a tiny gap so that both were never engaged at the same time and you use this gap to make it easier to move. The worms were steel while the worm wheels were large chunks of bronze.

If your wind turbine is built on the end of a tower, you could install a storage tank at the top and the bottom, and the wind turbine only pumps mercury up to the top. When the energy is needed on the grid, it can flow through a fluid turbine to power a generator. Since it's 13.5 times more dense than water, you need a much smaller volume of liquid.

Hi Guys. I've seen a rig made from scrap car parts that could be applied here with good effect. It was made for well digging - same sort of thing as here, an engine lifts a weight and drops it onto a pin repeatedly, driving it into the ground. It was a car rear axle, complete with diff, disk brake on one side and a wheel (no tire) on the other. The weight hangs on a rope wound round the wheel. The motor drove the drive shaft constantly. At idle, the disk brake rotor whizzes round and the wheel is stationary with no power to it. When the disk brake is applied, the disk rotor stops and the power is sent to the wheel, raising the weight. When the brake is released, the disk rotor spins free again and the wheel is also free to spin, and drops the weight. It always struck me as a beautiful use of a scrap mechanism with almost no modification required.

I would like to see some investigation into a transmission system to drive a flywheel and generator system, so the flywheel can be the energy storage system, maybe a way to refuse the power coming into the generator by diverting it into the flywheel when power load is lower on the electric generator than the input from the wind, so it can shift and take power from the flywheel when the wind load is lower thus the wind can always do input that goes toward either keeping the flywheel going as it is drained by the generator, or directly to the generator when the flywheel is at full speed you think is safe for it, then it would be cool to see if a multi staged flywheel system could be set up where the speed of the fly wheels causes clutching control and such so additional power not being consumed could be diverted to another flywheel in a chain so you could have a really windy day store up to a 3 day period of very low wind powered days worth of excess power to be drained :)

what about the mass dropped being magnets dropped through a bunch of coils?

Hi rob, anyone know where i can get hold of a nodding donkey or how to make one? Attach a gravity generator to one of them you can get it to refill the top with sand/water/rocks on the upstroke.

What about adding on gear down for what's planetary gear mechanism or a charging a spring instead of lifting a weight?

With a differential you can raise the weight from wind on one shaft and another source on the other shaft and if both energy sources are available at the same time then the weight will be lifted as much as twice as quickly due to the way the differential works.

Put a block and tackle on the shaft and raise a heavier weight more slowly.

did you consider squeezing together two strong magnets facing the same poles as the turbine works and releasing that energy when needed? main advantage over gravity is that, you need more energy to move the magnets as they get closer to each other.

Never ceases to amaze me this bloke. I've got an old disused bore hole in my garden. It's basically a 200mm wide steel pipe 35 meters deep this would work a treat stuck on top. Cheers Rob you've just provided a brilliant solution for how to utilise this old pipe.

Thanks. Love the mechanical design. I did a quick calculation - if I raise my 120,000kg house by 1m I could extract 330W for an hour while it lowers itself back to ground level, assuming no losses. Maybe I've calculated it wrong?

Seems about right Ben. 120 tonnes raised 1m is 1.1 million joules. 3.6 million joules is 1 kWh so you'll have about 0.32kWh stored there. About half what a 12v 70Ah typical car battery can store...

I was talking about it in one of my videos not long time ago. And, as well, I did calculations of how much energy + electricity we can store this way. I've used ChatGPT and the only thing which we should check is the time of the energy release. I was thinking about 3m high and 1 ton of water in an IBC. The calculations were promising to be true. Even if the efficiency would be 80-90% which is achievable I'd say, it's still worth doing. The only thing you need is a space and a bit of money cause you won't get everything for FREE for it ;). But, imagine if one block of houses would be able to install such system on their roof and use solar panels to pump it up each day ;). This can be mounted above the water storage ;). We're talking hundreds of tons of water, and that is a huge amount of energy.

1kg raised 1m is 9.8 joules so 1 ton which is a cubic meter of water - about the size of a washing machine raised to to the roof would be around 58,800 joules - as 3,600 joules is a watt hour then that would be 16 watt hours - more or less - my light bulbs are 40 watt equivalent light and take 4 watts - they are LED lamps - so it would be enough to light my living room easily - that small wind turbine is a model mate!! and if you used steel, concrete or lead it would be the size of a large shoe box, a two drawer filing cabinet or a small plant pot in that order lol

? worm gears are notoriously efficient - we clearly read different things - and it is a model to illustrate an idea - don't build the finish thing from plastic - seriously mate - really???
