[@erdemayaz1103]

Very good. I love it. Solar panels have maximum 20 years life time but this may have 120 years, moreover it has not chemical dependency.

[@jimmywrangles]

It depends on whatever gas you fill it with, from what I know hydrogen gas works well. it's a closed system though so no gas is released...I think.

[@LEO-xo9cz]

Moving parts might make it less reliable.

[@The_Bitruvian_Man]

Or slave labor to extract the materials

[@SimonSverige]

these are much more efficient than the best solar cells too.

[@SimonSverige]

am not sure the mirror would last 120 years.

[@jameselliott9397]

A two cylinder might run smoother. And I might suggest a copper heat sink to store excess heat. Very nice design and nice finished workmanship.

[@Micamicamico]

I dont know anything about this specific exact device but usually a stirling engine uses 2 cylinders to operate anyways. A loose one and a tight one. But yeah i agree a different engine config would balance better.

[@Deathbyfartz]

this some james bond villian looking stuff, and i love it :D

[@231squire]

That's beautiful, you should be proud 😊

[@19marco82]

Thank you

[@JustinTopp]

Looks amazing it could be a great source of emergency power for a radio or trickle charge a backup battery bank

[@Spoutinwyze]

i'd love to see the trickle charge a battery bank that could then be used to rapid charge a something like an e-bike/power assisted bike. be great to have one or two of these setup in the back yard, come home plug in your bike to charge while you sleep. drain your bike during the day while the sun charges resevoir.

[@CasamTheAnimator]

This technology was actually commission in 2010, and it was capable of generating 1 megawatt of power, this was later abandoned due to environmental concerns.

[@rosebreaker4320]

It does not have to be calculating the position of the sun all the time, that consumes energy, you just have to calculate it every 5 or 10 minutes, that drastically reduces the amount of energy used when aiming at the sun.

[@jondrayna6978]

Not really. Just to clarify, it's CALCULATING all the item. I assume what you meant was adjusting the position all the time. In any case, moving the reflector assembly takes a trivial amount of energy. Besides, if you energize the tracking motor for a quarter second 10 times or for 2.5 seconds once, what's the difference? Moreover, you need to hit a pretty small target. This is a beautiful tracking system. (From somebody who's built one. kzbin.info/www/bejne/r4ScpXimfd6mrLM)

[@icebluscorpion]

Is the Stirling pressurized? You get more torque and there for more power by same RPM with more pressure then atmospheric in the Stirling motor

[@thatguywithpiano]

Hey! How much energy did it produce?

[@chenelson185]

what you did for vibration & how much energy you get......just put next to a musician they sleep in the day

[@coconutdiarynomonkeybusine3495]

Add a heat sync to it. Will allow more torque from added pressure.

[@martinsite7665]

How much energy u able to generate on it??

[@gogutzy]

this is the future - i've also seen the infinia power dishes that were already installed in some locations. i do wonder if changing the focal point received to an evacuated tube would improve the performance...

[@absolute___zero]

the future is geothermal energy, will last for 2 billion years for all the people living on our planet. dig a 5km hole under your house and you can have it

[@jonathanmillner]

Able to scale it up, so the mirror is 2 or 3 meters across? Bigger stirling engine? Able to tie in to an existing power system? Something like that, I would interested to purchase.

[@aarondewindt]

I think one way to scale this up is by using single axis parabolic solar concentrators to heat up water, oil or some other fluid which can then be used to feed a larger engine. Temps are probably going to be lower though. Or have a central tower with the engine surrounded by a field of mirrors, you how it's done with a solar power tower.

[@nint68]

1:33 what about sticking a small solar panel there to get MORE ENERGY?) And it seems to me that it will be slightly cooled due to the working engine and, accordingly, heat removal (low temperature is important for the efficiency of solar panels), am I right?

[@Adam2023-q5k]

How does it work at night?

[@samueldominguez9859]

I wonder if it's possible to use your arm as a heat source to power a tiny stirling engine on a watch

[@alexandertheone311]

only 10 v? thats very low right? not much for house appliances...

[@nonchip]

i wonder how big would you have to build it so a generator connected to the engine produces more power than the autotracking requires... :D

[@isaaclowe7212]

It looks self-contained to me, I think he is charging the system then using the stored power to move the dish

[@jw3505]

I’ve seen tracking done brilliantly with tiny solar panels hidden just behind the dish. As they are exposed to the sun they power the motors directly, so it reorientates automatically with no constant power draw.

[@attiliobastosguarnieri5416]

Está tão bem feito que parece que foi comprado em loja especializada. Mas gerar 1 watts é deveras decepcionante. Acho que com vapor renderia mais energia. Não parece ser o objetivo. Funciona !! Congratulatios !!!

[@blackpowderkun]

Sterling engine converts energy more efficiently although yields less dense energy.

[@scottbobott1484]

Any idea on the efficiency? How many watts of power vs the power from the sun hitting the mirror? And how does it compare to solar?

[@aneeshprasobhan]

amazing garden, nice video, awesome built...is it 0.125 Amps or 1.25 Amps ?

[@0isay]

Great!! It perfect use solar energy. Im very interests in solar generator with stirling engine. Is it more efficient than solar panel generator?? About generating electricity, or other side...

[@brianlee5712]

It is possible to be more efficient than solar panels, but the thing is that the sterling engine must be optimized.

[@bloodstormwolf9512]

Stirling engines have the highest fuel efficiency, dunno about light efficiency.

[@DwAboutItManFr]

Are panels cheaper? Or can this compensate with a large enough area?

[@AshikChollangi1]

I am trying something very similar with Fresnel lens. Its light weight frame will be easy on tracking sun. Its a solar concentrator too where cheaper lenses are bringing in 90 percent of light.. And would like to talk to you if possible about your project.

[@ROCKNTV1]

excellent project sir, thanks for the video ;-)

[@ellinaras4566]

painting the point where the light hits will make it absorb more heat

[@19marco82]

ELLINARAS 456 , Any suggestions for high temperature coating? 350 degree and above.

[@ellinaras4566]

19marco82 that might be a problem, but my dad made a barbecue and painted black he used special paint fot extreme heat but idk the temperature and I don't remember what exactly he used go to a shop that sells this kind of things you‘ll find one

[@massimocorinaldesi8094]

for high temperature coating you have to use an high heat coating spray. I used for my rocket stove.

[@BushPilot444]

Yes, just buy paint made for boiler plate or stoves. I have been thinking about making one similar and in addition to painting it black, incorporate a glass globe to make it even hotter by trapping the heat around the element.

the principle is there, but the engine shakes the mirror. The wheel is tiny, so it would not produce much momentum to do very much.. Use a bigger dish, draw the heat away from the dish, heating oil and power a bigger engine.
