This gives me an idea that the device can be employed at reservoirs of water where the day sun heats one surface and the cooler water on the other surface thus forming a difference in temperature. This coupled with the heating surface being a solar panel as well will be able to function as dual energy convertors
We have used the ruclips.net/user/postUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!
I did this for my undergraduate physics project in 1979. The ROI period worked out at 100's or 1000's of years, but the cost of Peltier modules has since dropped a lot.
@@NwoDispatcher Yes. That is the principle. You keep one side cold, another side hot, then out of the terminals comes electricity. It works same way as the photo voltaics, just here in stead you use heat, while the photo voltaics use UVB.
@@NwoDispatcher: You can definitely combine them, but it usually depends on free cooling to be of any use. I could imagine doing that on a boat, like a catamaran, where the big deck would use photo voltaic and lead the excess heat to the water.
@@jeschinstad or in the desert and have a geothermal radiator deep in the ground. Wonder if they use em in space. I hear has crazy heat differential... also, when they say heat do they actuslly mean infrared?
These are great for their wide range of fuels that may be used. Also, NO BATTERIES needed! Store the heat in oil, insulated of course, and when you need it, pump the hot oil into the system. You could even start it by a valve with no other power sources required. Efficiency is important but so is utility. FYI, the batteries are the most expensive and replaced first in any system that is using them.
I think you are correct about replacing batteries with hot thermal oil for on-demand power when the sun is not actively heating the oil. Build a large, insulated “thermos” to hold the hot oil coming out of, say, a parabolic trough, then use that hot oil to provide heat for the thermoelectric generators whenever electricity is needed. If you want more flexibility, incorporate a rocket stove into the system for the ability to heat the thermal oil during times when the sun is not shining on the parabolic troughs. Cleanly burn waste materials that might otherwise go into landfills, like junk mail, yard waste, cardboard packaging, ect... in the stove.
At 4:27 are you sure you meant to say vacuum chamber? A vacuum chamber is a chamber with no air in it. Isn’t the greenhouse effect impossible without gases to trap the heat?
Dear SYnergy Files, thanks for your sharing and your time spent on this valuable information. You mentioned various practical things about the heat absorber, concentrating sun on the STEG element. Can you give some guidelines as to how we can make the best use of it? We are thinking about cooling the back side with water, and putting concentrated sun on the front.
Would coupling a PV with an active cooling system be more efficient? Using water as a coolant could cool the PV cells down and provide us with warm water directly. Less conversions of forms of energy
No, a PV cell only works in certain conditions and at certain times of the day. A teg will work( provide power ) anytime with any heat source. Solar panels are a joke when it comes to conversion, the fact that a shadow shuts down the entire panel, and the obvious amount of space and work needed to keep them going like cleaning then often, snow cover, rain, wind damage, ... You get the point. Not to mention to overpriced components to make them work. Its not as if you just buy a panel and point it towards the sun. You must first have a an inverter, then a charge controller for the massivly expensive battery bank that will need to be replaced within 5 to 10 years. The engery potential in hours of darkness, rain, snow, cloud cover, and all of the other times solar panels are useless make thermoelectric way way more useful and practical.
Yea this is already a thing, i think it's called hybrid solar. My idea was using the PV solar panels themselves as heat collectors for Seebeck generators in the back.
Sounds like this would couple synergistically with a Rocket Mass Stove that incorporates a water heating unit. The Electrically insulated material could be the cob (mass) which is also thermally conductive and the mass gives off high radiant heat for days after only a 1-3 hour burn (twigs, pinecones, junk mail). The RMS also burns very clean because of the catalytic nature of thermosiphoning. I wish I had plans to build (or knew where to buy) a STEG unit as you show on this video. I'd love to give this a shot and see if I can make it productive. Thanks for the video.
Depends on level and quality of cooling, and on that if passive or active... The higher the difference, the better... Just to get the principle: 300°C to 450°C is better than -120°C to 0°C, which is better than 0°C to 100°C, cause the difference in the first case is 150°C, while in the second it is only 120°C, and in the third, even worse, just 100°C... The difference depends after all only on you, and on how much you are ready to spend for a good, elaborated cooling system...
What about taking a TEG and sandwiching it in a PVT panel? It could produce electricity using the heat from the panel and cooling the back side with water generating hot water in the process. Since there would be a high delta, I would thing it would be more efficient. If you added a controller and temp sensors, it would be possible to run the TEG as a TEC producing higher temp water extending the amount of hot water that could be produced in cooler climates. Or using the TEC to keep the panel at an optimum temperature to extend life and increase production. Very little energy would be wasted because it would be transferred to the water for heating. Just an idea that went through my head as I watched this.
nice info.. Where are the thermoelectric/thermocouple panels about the size of home solar-panels? Big money talks. I guess this stuff get's the back set? 😎 Thanks.
Well done for coming up with this idea independently. Yes you can. The challenge will be to find a Thermal interface material that is electrically insulating while thermally conductive to place at the back of the cell. You can find these materials online or RS components
Okay, so a thermal paste I use on my CPU? I haven't explored thermal electric generators much or PV. I recently was reminded that TEG works by seebeck effect? I always just tell people there's a charge created in two metallic parts with a temperature differential. the larger the differential the larger the charge. It would be really cool to learn more about renewable energy and micro electronics. I think the low-energy technologies people are developing will couple well with renewable energies. If we can bridge the gap between renewable energy efficiencies by making the devices we use more efficient ... Say, there's another technology that randomly popped into my head a couple years ago. I googled it and foudn some patents were already made but it was something like passive gas ion collection. it involved a grid whereas gas passes over a vertical grid (wind in the sea) the gas is charged as it passes over the grid and then that charge is collected by a hoop downwind. I wish I could remember what that technology was because I wanted to learn more about it, I think this would be one to couple with wave generation (magnetic induction via kinetic motion of the sea) and use the water to control the temp on your STEG ... the passive gas system offers electrical generation with very little moving parts. I would imagine the charge-grid would erode over time. Thanks for reading and writing.
Yes the same thermal paste. However make sure that the paste has dielectric strength. There is an upcoming video in which I will be looking at ionized gas, but for a totally different application
Could Thermo-Electric work in a Deep Geothermal set up? I've heard 12 kilometers down it gets as hot as nuclear rector. The other Deep Geothermal plants require a fat line and use water for steam power terrible generator. With a Direct Conversion to Electricity it would cut the need for those requirements.
I'm still taken back by how a desert can exist in 2019, I can't fathom why people is hot sunny counties/deserts don't utilise to process of convection with condensation to create water. I'm sure it's not rocket science to have solar powered turbines pumping hot air into a much cooler subterranean holding tank in order for that exceedingly hot air to condense back into drinkable water or why not go the whole hogg and have that cooled water then being pumped past the lower chamber of a Stirling engine to then go on to generate power that's being lost by the solar powered turbine pumps. I feel that the more we attempt to cover our planet with solar panels the cooler we're going to make the surface of the planet which I really don't see as a productive endeavour because the cooler our climate becomes the less likely fundamental crops will be to grow and may even lead to us sparking off a mini ice age like that of the 1800's when the River Thames frozen solid. Swings and roundabouts really, we can plaster the planet in solar panels and risk inducing the arbido effect and potentially wiping out a considerable portion of all life on the planet when we go into a gradual freeze OR we can harness things such as hydro power and then use that very power for electrolysis of water to give us some clean abundant gas as well as the water recondencing back into fresh drinking water. Places like California should be all over these kind of simple ideas with them having to pipe in fresh water from other states. I thought Cali was the sunshine state a lot like Florida because they're on similar latitudinal lines. Surely makes good sense to take advantage of all that sun and heat.
Actually there's plenty camels aren't solar powered buddy 😉 You might want to watch some caravans, the water is there humans couldn't live there if there wasn't.
2- When you say that it is 5% efficient, may I ask, how is that calculated? Let us say that we put 300 degrees on one side, and 40 degrees on the other side, and out comes 2.5 Watt. Then I understand your video such that we then have a loss of 95%, or, 47.5 Watt. That effect can only get lost via the cooling water, is that not right? If that is the case, and if we dimension it correctly, then if I am not mistaken, we can keep a thermal storage 300 degrees hot, and then when we need power, we open up for the cold water, and then we will get power from the terminals, while we also heat up the water equivalent to 47.5 Watt. Is that correct?
I have been thinking on utilization of both Solar light and solar heat simultaneously to generate electricity. If Peltier modules can be placed below the PV panels attached to it and heat dispensers are also fixed to transmit heat through Peltier modules, so that heat collected on the PV panel is absorbed by Peltier modules and generate additional power. Reduction of heat on PV panels will increase the efficiency of PV panels to get more electricity. Can any one tell me practicability or otherwise of this new idea? There is no necessity of storing energy in large sized projects because power can be utilized immediately through power gird for energy requirement during day time.
This is not a new idea. Research has already been done on PV panel with Peltier. The conclusions suggested that PV life can be increased from 30 years to 50 years in addition to the extra output
Thank you very much. If you come across any report of findings etc., kindly give information. Also kindly let me know how can I contact you by email. I am a retired person and not having any detailed technical knowledge. So many times I come across such ideas. It will be helpful for me to satisfy my curiosity. I have designed a new type of flyover to decongest city traffic. Many Engineering colleges have opined that it is a new and practical idea but I am unable to get it accepted by government officials. I once again thank you very much. Can you keep in touch with me if I give my email ID to you ? After verifyinjg many vidios of solar light energy conversion by PV I throught of asking this question. In none of the RUclips videos I saw any usage of Peltier used with solar PV panels.
0:36 This has nothing to do with reliability and durability. This is usually an outdated promotional argument issued by consumer companies. everything is related to good design not to solid state or fluid state.
You forgot to say that Stegs may be more sustainable, cause they work because of heat, and so, can bear heat, while PVs hate heat and get older faster when not properly cooled (30-year PV-lifetime when not cooled instead of 50-year PV-lifetime when properly cooled)!!!
I don't think thermal electric will really take off. unless the efficiency is greatly improved. the typical peltier plate works better cooling. than generating.
I think there's some ways to integrate TEG into systems we already use to create what I call regenerative charging. Theoretically we could all retrofit our gas-burning cars to carry a TEG ... like you say though efficiency is a big thing.. you don't necessarily want to add a 200kg TEG to your pickup so you can listen to the car speakers with out using the car battery. You're not quite making enough power to run everything but it's a bit ... like maybe a CPU cooler that has a TEG built in, that TEG charges a USB bus or your laptop battery a little.... or eh, put a TEG on your camp lantern near the elements or a camp stove with a TEG(this is real already). STEG is just another piece of the puzzle. There's a cool thing with phase exchanges and capillary action ... so many cool things, regenerative cooling on rocket engine shrouds is another clue. I have a lot of raging clues pointing in different directions.
Too bad that it's so hard to turn heat directly into electricity. Because I thought it would be easier than PV systems because the sun easily heat surfaces and could be transferred into electricity

How much does the technology weigh per square inch compared to its photovoltaic counterpart?
It sounds like it has potential, but seeing is believing!
Would it be better if we paint it in vantablack?
does steg degrade over time like PV collectors? This may be another advantage.
so what is the 'cold side' material for the offloading of heat efficiently?
Can these vacuum sealed modules be used as replacements for the photovoltaic cells in Power over Fiber systems?
Do you have a Kickstarter? also do you intend to sell portable units?
