The Red River college flat panel sterling engine is absolutely brilliant and would seem to be well with in the reach of an ordinary Muggle with a home workshop. Would love to see you tackle this one Rob . Cheers mate ☺

[@ThinkingandTinkering]

it's awesome isn't it

[@FinGoju]

That flat panel Stirling engine was awesome! Thank you Robert once again for bringing up these innovations. I need to build a sand battery and put that kind of flat stirling on top of it to have some power during the night. We are now pushing around 30 kWh altruisticly to the grid on a sunny day with solar panels...

[@ThinkingandTinkering]

i agree - the flat panel Stirling is awesome and with improvements that can be made for sure

[@drillerdev4624]

​@@ThinkingandTinkering I've been thinking for some time that a sterling engine could be a solution for mild but productive refrigeration, something that attached to solar panels could even boost their efficiency. Do you think it could be feasible to use that flat engine as a base and substitute the top with PV (lightweight) panels?

[@BillHallProductions]

I found that flat panel stirling a while ago and I thought it was brilliant

[@ThinkingandTinkering]

it is

[@JSabh]

Thank you, I always enjoy anything to do with a Stirling engine. I have seen you make some amazing ones over the years. The one in particular is the one that looks like a can with a balloon stretched on top, that thing ran so well and was mesmerizing. Hope your having the best day possible my friend.

i do love Stirling engines mate and they are surprisingly efficient

[@petertrypsteen]

@@ThinkingandTinkering Loved the low-temperature stirling engine cameo. How efficient is the Red River College solar thermal Stirling engine?

[@Charlie-Oooooo]

Great presentation of solar thermal power gen! Another cool thing about Stirling Gen is that since it works on temp difference, the same system will be more efficient when the cold side is made cooler - like in winter! Cool👍

[@richardglickman7203]

I don’t know what surface material the RRC solar sterling engine uses to generate their heat, but the instant I saw it I thought of solar cells. It would increase the total device efficiency and help cool the solar cells to extend their useful lifetime. Seem like a very symbiotic pairing.

[@kadmow]

Sirprised Rice University didn't use flash carbon/graphene - as the nanoparticles for thermal transfer.

[@kevinsigaard]

Just think if we build houses from scratch in a symbiotic way of thinking where every houseappliance generating heat, went into the same heatstorage as all the other houseappliances generating heat. Where solar, wind, geothermal and other generators was considered in the design of every newly build house. Where watercollection was considered in the design. Sortly said, where the symbiotic multiplesolution was explored and considered like here on this channel. Then add that approach to reconstruction. Imagine the change that would bring if applied generally, it could prevent a lot of pressure on the backs of families across the world.

[@offgridwanabe]

Fresnel lens sand battery using molten salt for heat exchange comes to mind, I guess it depends on what you want to end up using for your power to appliance ie. heat, electricity, mechanical, etc.

Thanks mate. I have not heard that before about nanoparticles. It opens up all sorts of possibilities. I like anything on how to create electricity from the sun, and some of these methods look like they'll do it without any expensive and dangerous materials.

Concentrated solar thermal power also literally fries the birds in flight that happen to traverse through the beams. The closer to the tower they happen to get before they cross the beams, the faster they cook. It’s quite gruesome what happens to them, really.

[@ThomasAndersonbsf]

it seems the nano particles give two things then, because only one is the absorbing light to covert it to heat, the other being they become nucleation points for the water to expand into steam, so the water does not super heat with out boiling due to everything being ultra smooth, also I guess a 3rd thing it gives is that the nucleation points are right where the heat exchange is happening from light to heat directly to further facilitate efficient boiling of water.

[@ch5139]

Until recent times, I think most people’s experience of solar power was a dancing monkey or sunflower on their window sill….I wonder what the total generated power of all those millions of novelties is? now that’s micro generation. I saw a car with a dashboard full of them, and it wasn’t a Tesla!

[@ThinkingandTinkering]

lol - i wonder too now !

[@patricklyons7683]

Lovely share sir

[@ThinkingandTinkering]

cheers mate

[@travismoore7849]

Solar ions are the easiest way to make power. Where you use nano particles to collect static charges from the upper atmosphere and use a on off switching of the antenna to a ground connection to run a transformer in the circuit to make electricity. Though could you use a radioactive source to make ions from chlorine and nano carbon and switching on and off between the nano carbon and a ground with a transformer for a crude form of nuclear power? I guess the ion density would determine power. And the lower the more easily a particle is ionized the more power it would make.

[@DavidWilliams-yh6pq]

Using your solar heat collector and something to disperse that heat in the middle of tesla wind turbine, the thought is to rely on aid from heats tendency to rise to increase efficiency.

Boil heavy water

[@Arturo-lapaz]

Not necessarily .. Helium gas cooled reactors can use gasturbines without the relatively inefficient steam process. No boilers, no multistage separate units, no condeenser, no water preparation and meticulous cleaning make up water. The advances of gasturbines and compressors in aeroderivatives is not to be discounted,

[@ThinkingandTinkering]

How many are in operation?

[@Barskor1]

Water boils so much easier in a vacuum IRC it cuts the heat needed to a third of what it normally takes to boil water which expands a systems operating range IE you don't need to live in sunny places to get it to work and or burn much less fuel.

[@Arturo-lapaz]

That is not true , the evaporation enthalpy is the least near the critical point of water, high temperature and pressure, look it up.

[@ThinkingandTinkering]

it does mate - but it then depends on what you want to do with it - for desalination vacuum distillation with barometric head is a great low power system - but if you try and run an engine from it you won't gt the same power out as there is less energy going in

Would a Nitinol engine be easier to build than a Stirling?

[@BillHallProductions]

My understanding is the problem with nitinol engines is the meal doesn't last long enough to pay off It eventually starts to degrade in some manner

[@zenile7087]

Unfortunately, Nitinol alloys are involving phase-change temperatures, it demands times and a huge gap of temperature to ensure annealing THEN quenching, then a new cycle. A Stirling engine common way of improvement is to increase the thermal capacity of the working fluid. Compressed pure hydrogen is used in nuclear power plant to ensure a stringent cooling of the very powerful alternators, which are imprisonning this flammable gas in a closed-loop of ...viscous oil. To ensure that the rotating shaft will never touche the static, immobile parts; by having a circular "viscous oil cushion". Inside, it's hell with hydrogen. Outside : very qualified servicemen which are walking next to this mighty equipment, weighting hundreds of tons.. In a Stirling engine like the SOLO 151, compressed hydrogen up to 700 atmospheres of pressure is used. NO SCRATCHES on any assembly, planar face is allowed. Very very gas tightness is required, to obtain yield close to 40%. A very high technology to make such external combustion motors. Best regards

At threat of ridicule, nano particles - old car oil!!

[@zenile7087]

Nope, the gradient of high temperatures flowing into the chamber of the solar furnace leads to "cokeification" of common mineral oils, leading to scaling of huge coatings of adherent bitumen, then highly viscous tars, then almost a coke-like nasty matter, with plenty of pyrolisis-made holes of void in it. Nanoparticles are used to enhance thermal conductivity AND stabilize the heat gradient, as much as possible. Avoiding "calefaction" as much as possible. Temperatures can reach as high as 1100°C. Very few alloy can withstand this, leading often to creep, "blown internally" of pipes and vessels.
