Archimedes Hydro Generator - Making the Body

[@thornhedge9639]

Hey Robert; the Screw you made is a piece of standard equipment in grain silo loading setups. Is is available through Ag supply companies and is metal to boot. Bonus: it is available in the correctly sized pipe. Just in case you are interested.

[@ThinkingandTinkering]

cheers mate

[@igloobearred]

I'm soooooo glad I'm not the only one who performs better too eat the cake rather than to decorate! Lol Love, love, love your channel friend.

[@ThinkingandTinkering]

lol - cheers mate

[@William_Hada]

I really like that technique of using expanding foam to form rigid bulky structures!

[@ThinkingandTinkering]

cheers mate

[@thornhedge9639]

Yup, I looked at prices on those screws just for Kicks (forget I mentioned it) Great build by the way!

[@ThinkingandTinkering]

lol - yeah I thought they might be a bit expensive

[@stevetobias4890]

Very cool. Something like this could be adapted to the downpipes to use the rainfall from your gutters to generate power. Even using a natural fall in a creek on your property would generate power as long as water is flowing. Very cool indeed, I can think of so many uses for this.

[@ThinkingandTinkering]

I would like to see that - I am sort of hoping someone will take up that challenge mate - hint hint lol

[@darrellpidgeon6440]

Brilliant use of the foam! Lightweight and rigid enough for this purpose. I'll keep this in mind for some of my projects. Thanks.

[@ThinkingandTinkering]

it's pretty cool stuff that's for sure

[@ThisRandomUsername]

There aren't many of your videos that have disappointed me Rob. This is pretty impressive stuff!

[@ThinkingandTinkering]

cheers mate

[@sofa-lofa4241]

Nice idea for the former, foam finish is better than I expected, good job!

[@ThinkingandTinkering]

Thank you! Cheers!

[@Buzzhumma]

The best thing about the screw is the water continues to exert pressure on the entirety of surface creating turning force for the whole length unlike a propeller design which once done with the small surface is forever lost and as it is enclosed for the area with water, there is minimal angular loss as opposed to a propeller that whisks the water away to the outside reducing effeciency!

[@ThinkingandTinkering]

for sure mate

[@jeffreyrood8755]

I was checking out the Archimedes screw a good bit last month. Glad you made this video Mr. Rob.

[@docink6175]

nicely done, most expanding foams will kick off better if there is moisture, mist each layer and let it expand before adding another

[@ThinkingandTinkering]

Thanks for the tips!

[@DeliciousDeBlair]

I've used that type form [as well as aerosol foams professionally in the construction industry, and they make one which expands less, but also sags less, so you can use it specifically for making shapes from, without it falling off before taking the shape you wanted and hardening.

[@ThinkingandTinkering]

oh - what's the name?

[@azlandpilotcar4450]

Great series. I've always wondered if a multiple helix screw would work in this sort of application. Archimedes seems to have missed that with the correct pitch, one can fit more than one screw over the same shaft. I know that it works for some types of hardware and auger feeds. Looking forward to more.

[@ThinkingandTinkering]

you could do multiple flights for sure mate

[@BillHartCooks.]

Cool.... I want to come play in your workshop. I have been trying to come up with a version of this for a while. The Archimedes Screw Generator, not the foam forming. Where I live we get a pretty good amount of rain, and sometimes several inches within hours. Anyway watching all that water run made me think of capturing some of the energy and I figured a series of switch backs over a relatively steep but shallow slope would allow the same water to turn multiple generators. I tried to do some of the math but I am not sure if I got it right, but I am thinking that the longer the screw (with more coils) the more force could be captured from the same amount of water... Anyway This series is very cool to me... Keep at it

[@TimeSurfer206]

Do you live in Skedaddle, Warshington, too? Because every time it rains here, I'm looking at the off-flow from the roof of the (unfinished) house I'm next to, and think about all that wasted energy. This looks like the way to go.

[@kenrowe167]

Hi Rob. Looking at commercial archimedes hydrotubines, they all seem to have 3 flights intertwined co-axially, so that there are effectively 3 inlets for the water at the head of the penstock. I couldn't find any paper on this, so I don't know if this arrangement increases the efficiency, the power output or both. But they must be doing it for a good reason.

[@ThinkingandTinkering]

I did see that mate - well worth adding another one for sure

[@BoB4jjjjs]

Some smooth flue pipe would be close to what you need, but any sheet metal works would roll you a pipe in no time, though it would have a joint, it could be on outside and smoothed on inside. I wish I was near a stream I could play with that and a water wheel to produce my own power, and a wind generator.

[@Buzzhumma]

I have always felt they would be great in downpipes from the roof rain as they already have an enclosure but under heavy rain they would not dissipate the flow fast enough so i thought an second external downpipe would be the answer !

[@ThinkingandTinkering]

I don't know mate - worth trying it I would think

[@marcelinuskevin631]

Hi, awesome video. Just to make sure, what is the material that you use for the frame or the body?

[@garywillis5790]

Cracking idea! Looking forward to seeing it working!

[@ThinkingandTinkering]

next vid mate

[@joohop]

Smart Work Rob . I've Thought Putting That Expanding Foam In My 2 Man Inflatable Kayak For Rigidity, Mmmm We'll See .... Bless Up

[@brainretardant]

Make sure you use closed cell foam. Some foam actually gas a sponge network that will fill with water. I'm going pool noodle on an old zodiac

[@ThinkingandTinkering]

this type needs exposure to the air in order to cure mate - so I would think you would need a two part type that didn't need that - but you can buy them for sure

[@joohop]

@@ThinkingandTinkering Ok Cheers Buddy

[@Cooliemasteroz]

You’re a true craftsman, well done.

[@ThinkingandTinkering]

cheers mate

[@TimothySkinner_photographer]

Have you considered putting magnets on the edge of the screw and embedding the coils in the base and walls rather than attaching to the axle to get the highest RPM for the generator? It may provide increased electrical output?

[@Killianwsh]

Great build Rob!

[@ThinkingandTinkering]

cheers mate

[@hissst69]

Awesomely simplified ! I wonder if you are going to do some more electronics too? I really enjoyed the energy harvester and doing bits and bobs with motors, making small circuits and such, would love to see how you would approach finding resonance in a tank circuit for example if one didn't have all the special equipment to find such resonance, and even a demonstration of a circuit out of resonance vs all tuned up. Regardless, I love what you do and happy to watch you in any direction you go as long as you continue having fun and making the world a simpler place :)

[@ThinkingandTinkering]

there is a lot to do mate but I will get round to it sooner or later I would think

[@12thsonofisrael]

EXCELLENTE'! Great example of in-place molding.

[@ThinkingandTinkering]

Thank you! Cheers!

[@MultiOutdoorman]

If you hold the can vertically (nozzle at the bottom) you wont expel too much propellant and the contents will go further...

[@Barskor1]

Nice I think they call that foam Great Stuff and using it for sealing window frames in houses in the USA.

[@ThinkingandTinkering]

they use it for the same thing here mate - but it's just called expanding filler or expanding foam

[@jeffreyrood8755]

I want to get or make one about 3'' diameter and maybe 24" long to go in the down spout of my gutter system on the house. Thats about all the water application I have right now.

[@campbellspears3929]

I've pondered that thought too.

[@jeffreyrood8755]

@@campbellspears3929 Do you think you will pursue it? If so I have a video from a KZbinr that I can look up that kinda did some stuff with it if you're interested?

[@stuffoflardohfortheloveof]

Interesting Rob......can’t wait to see the next ‘episode’.......it’s like I used to be with Grand Designs 👍😀

[@ThinkingandTinkering]

Cool, thanks

[@conductiveinkalternative918]

Even airflow will turn this from all directions!

[@tombrooks2015]

always have the can upside down or you will not use all the foam ;)

[@ThunderDivine]

And moist the surface u spray first with water it will expand better and more with less.

[@ThinkingandTinkering]

cheers mate

[@Cooliemasteroz]

Hey Rob l’ve had a thought that won’t go away. What if you made one that had a spiral that went from a large diameter at one end down to a small diameter on at the other end inside a cone. I was thinking that if it were used to generate power from water then with the large diameter at the top it might not need to be as long as a parallel set up and be able to work as well if not better with a greatly variable water flow. I suppose an experienced mechanical engineer would know the answer but it’s good to experiment.

[@ThinkingandTinkering]

that's interesting mate and very do able with his technique I would think - you would make the central core a cone and follow it round - itch would probably change thought

[@punchogunter2362]

How can I build a generator powerful enough to power my home?????

[@ThinkingandTinkering]

build a big one of these if you have water - a big wind generator if you don't or buy a lot of solar panel - if you have never built anything before you might want to start small just to get your hand in so to speak

[@BushImports]

Nicely done.

[@ThinkingandTinkering]

Thank you! Cheers!

[@iamkian]

Can you make a water wave generator?

[@ThinkingandTinkering]

sure

[@endadalton]

Totally ingenious
