Testing The Archimedes Screw Generator In A Car Park

[@undernetjack]

Awesome mate. I live inTexas, so real hot most of the time. I am designing a rooftop water hose storage system, to save energy. Basically two hundred feet of black hose laid out in tight spirals absorbs heat and is fed into the water heater's inlet pipe, increasing the temperature of the tank water, therefore needing less energy to heat up.

[@joinedupjon]

That's a really great way of collecting solar energy.

[@undernetjack]

Vox Deus Thanks. I was actually looking at some 1" black pex type tubing that is for hot water. Good call.

[@ThinkingandTinkering]

nice one mate - I like that system a lot - cheers

[@billschas9202]

Wes Goodman Wes, I grew up in Texas, and spent the last 15 years in San Antonio. As the hot season has gotten longer, and the hottest days more intense, I noticed that large parking lots have become particularly unpleasant places to spend time, especially on a summer afternoon. It has come to mind that a parking lot that occupies several acres ( not uncommon in San Antonio) is storing a tremendous amount of heat. The idea of imbedding some sort of heat exchanger in the black top and harvesting the heat for use with a Stirling engine or Peltier generators is intriguing. What do you think?

[@undernetjack]

Bill Schas Brilliant. I was thinking of something along the lines of turning the blacktops into some kind of low grade photovoltaics, but I like your idea better.👍🏻

[@stevetobias4890]

That was really cool, I knew that would work. Once I finish the projects currently piled up on my bench I intend to build a couple of these. I agree that the success revolves around matching the right generator to the application, this would directly impact on efficiency.

[@ThinkingandTinkering]

very much so mate - I often get exasperated by folks who say that's not' generating much' as in a simple lash up all you really can tell is 1 - it works to some degree - 2- you now have a minimum

[@martinwinfield2935]

I found this video and demonstration really interesting and useful. I have a small stream on my land and have been looking at different options to try. Im going to have a go, I do not need lots of amps just enough to charge a small gel cell for a wildlife camera. Thanks for your hard work.

[@ThinkingandTinkering]

that is awesome mate and a really good use

[@Draakdarkmaster6]

for a basic mockup thats some nice voltage, and thats not even a high pressure water supply, imagine a streamlined and optimized design a water pipe with higher pressures of liquid flowing through it, i may have to try building one of my own!

[@Killianwsh]

Hmm .. I wonder if you could recapture the entrained air bubbles as the water flows out the bottom in to a well placed inverted funnel catch chamber and then utilize the pressurized air to power an airlift pump to increase your initial water flow volume or to directly aid in shaft rotation via shaft coupled turbine or simply reduce friction on the shaft via air bearings. Great demonstration Rob!

[@ThinkingandTinkering]

nice ideas mate - thanks for posting

[@jeffreyrood8755]

I really like it Robert. Very well built. Great work as always sir!

[@ThinkingandTinkering]

Awesome, thank you!

[@AdricM]

if it has the torque, might consider a 12v or 18v cordless drill, hook up the screw to the chuck end. and bypass the trigger and let her turn... if not for this, then perhaps for the gear bike.

[@ThinkingandTinkering]

it should have the torque for that for sure mate - cheers

[@MolloRelax]

a ceiling fan motor shaft, hooked up to the end of the screw might generate power efficiently....they are so easy to turn

[@georgehughes5385]

A simple solution to scavenging energy is by having small 'windmills' sat at the side of motorways or fast roads so that air pressure from passing traffic would provide power for electrical street furniture or street lighting. A simple system of plug a 'windmill' into a circuit, much like a light bulb circuit, would provide power where it is needed. I could just imagine having a line of them on top of crash barriers would do a fine job. Have you felt the draft as a lorry passes close by?

[@MolloRelax]

Not sure where I have seen what you are describing, but it was deployed between two major high traffic highways...in some country .....Europe if I recall right

[@MolloRelax]

.....short search produced this Patent,,,,just plug the: Traffic-driven wind generator: in google search window

[@TheYetiownz]

As a rookie, I was wondering if you could charge a battery bank with Archimedes screw if its scaled up to like 15 volts... WIth somewhat of a system scale up and finding a faster current would that be generally feasible? I saw your video with the stream test producing 5v

[@binmanblog]

I have an idea to use it for rainwater harvesting which needs to be pumped to a header tank. So this could be a really eco solution. I especially love the idea that rainwater power pumps itself up to the header tank.

[@ThinkingandTinkering]

I like that idea mate

[@williamfoster6172]

What is meant by matching the generator to the mechanism? What measurements come into play?

[@herbetone]

Excellent video, whats is not to like, great demonstration.

[@ThinkingandTinkering]

Much appreciated - cheers mate

[@scottjamieson7300]

remember the pipe with the muscle that worked with wind& vibration.I asked if you could test it in wathe perhaps it's the perfect set up you have now too test it ? it would be a very intestine video & I think !very informative like all ýour videos bro be blessed

[@ThinkingandTinkering]

Great suggestion cheers mate

[@CBurton0001]

I’ve really enjoyed watching ur videos. But I can’t seem to find anything about the mechanism for the water screw that would use the power of the water pulled up to power the rotation of the screw. Something like a gear box that’ll transfer the needed torque for the screw from the second function of another combined setup. Water screw + turbine = free infinite water. Completely self sustaining! If u have any info on that I’d love to c it

[@ThomasAndersonbsf]

if you had time you should try building a unidirectional horn to concentrate wind into it (closing the top off so the air going down from the horn design, is forced to flow through the screw design) could be a good way to show the value of a omnidirectional one based on sections facing each direction, with maybe 4 or 8 segments, for north south east and west. or adding NE NW SW and SE :)

[@ThinkingandTinkering]

it's a good idea mate - but you know what - it would be awesome if you gave it a go - after all this is just cut CDs and foam

[@ThomasAndersonbsf]

@@ThinkingandTinkering definitely, I am working on figuring out this whole geopolymer thing, with local resources, as I want to see if I can make part of a house using them, ;)

[@fk2106]

I couldn't read the values generated for volts or amps. What were the readings?

[@DreadX10]

2.4 V , 110-120 mA, 2.6 V

[@mongoslade5248]

Useful during the rainy season.

[@ThinkingandTinkering]

[@ryanlebeck259]

Fantastic recreation of the Japanese system. I'm working on a standing unit that might be useful in the UK for hydroelectric generation within a hydraulic system in equilibrium that your batteries might be just ducky in 😊

[@ThinkingandTinkering]

cheers mate and sounds interesting what you are up to

[@joinedupjon]

Might not start reliably where there's just a trickle of rain... But could be improved with either a 'Tippler' or a 'urinal syphon' to send the water through in predictable sized surges that you'd be able to optimise the generator for.

[@ThinkingandTinkering]

I would say it definitely wouldn't mate - well not unless the tolerances were much much better but then that would increase the expense - but nice suggestion on how to overcome that - cheers mate

[@darrellpidgeon6440]

Great test! Since I like table-top fountains (the more unusual the better), this gives me some ideas. Of course I would have to do some scaling down. Good work; thanks.

[@MAGnetICus_Attractus]

I got thinking the same thing. Done all sorts of things to my water fountain on my porch.

[@ThinkingandTinkering]

Glad it was helpful!

[@steverichmond7142]

There's a lot of small streams and land drains on hills in Scotland. Just finished the wind turbine... next

[@ThinkingandTinkering]

that would be a good place to try this mate

[@ryanlebeck259]

Could you hook up a hydraulic ram pump to a reservoir uphill to boost water flow back downhill. You can only use 10% of the water from the stream, though it would be interesting to see what that would accomplish.

[@steverichmond7142]

@@ryanlebeck259 I think a ram pump takes quite a bit of energy and it could mean you are putting more energy in than you are getting out, but I could be wrong.

[@ryanlebeck259]

@@steverichmond7142 as a matter of "cost" a ram pump only has the associated materials cost to put into operation. The water is already flowing, so you would be 'building up' the water flow mechanically to scavenge higher power yields. The process would still be scavenging power.

[@gorille151]

Any news on your battery prototype? Subscribed 5 years ago for it. Seems i will never see it.

[@dungc6479]

[@ThinkingandTinkering]

yes you will - I do where are we now videos every now and then - you should check them out but basically youtube is a views oriented platform - no views, no youtube - therefore no point in making the video. I hate to point this out but the irony made me smile - if you think about it - you are talking about videos not being made and when I made a video it is obvious you didn't watch it - even though it is a topic you are interested in - I am not moaning here mate - just pointing out the irony - cheers

[@Earzone63]

I wanted to dream up a way to store up excess solar energy in silly-hot countries like Cyprus without the expense/limitation of the battery bank.. I came up with a G.P.E 'Water Battery' which stores the excess by pumping up water (from the swimming pool maybe). I gave up when I factored the hours-of-life / cost for the commercial water turbines... but now this might make the idea viable :D

[@steverichmond7142]

Look at liquid air using compressor with old commercial fridge unit. Micro model of Manchester unit

[@ThinkingandTinkering]

[@Flashahol]

These small generators are all great, but what about an accumulator to make it all useful? I'm thinking some different generators (wind, water, solar...) made from recuperated parts, all linked to a main power accumulator that can then be used directly or directed into batteries. If I followed all my fantasies, my neighbours would call me eyesore.

[@ThinkingandTinkering]

did you know they used to call batteries an accumulator?

[@Flashahol]

@@ThinkingandTinkering Good point. What really I mean is a way to connect multiple small generators to one central accumulator (could be a battery, but I'm thinking cheaper) in a way that you may have some immediately usable current to power something small and/or use to charge other batteries at the same time. I bet it would take a small farm of generators like this, though.
