This is clearly one of your best videos. The tracker causes focused solar radiation to continuously illuminate a single point and many new potential applications exist. If the fresnel lens is lowered so that it's focal point coincides with the lower pivot of the tracker, the focus on the target will remain constant throughout the day. It is also possible to pivot the target with the tracker, if desired. Good Job!

[@franciscocontreras4450]

Hi Rojas, I was just wondering a thought accord to me that your idea could definitely be used to warm swimming pools in the winder to go swimming anytime of the year... I was kinda picturing a connection system to pump the water through while the sun is out to warm tje water up, I guess over a few days it will reach 80+ degrees Celsius or Fahrenheit not only that but it could be connected with a computer to keep it at a certain tempature for practically free. Could you create a video about this for other to take to newer levels, please. I personally believe it will inspire many and will definitely buy these units to add to their swimming pools, even private communities will invest in them or resorts, etc. Because I just went outside its very cold but it would be nice to go for a swim in warm water, but as we all know that it would cost lots of money and the electricity bill will sky rocket. So this solar ray, if built by professionals it will be in assuming the safest possible for anyone to opperate in every household that happens to have a swimming pool not just that but others would then be more inclined to invest in one just because of this concept of yours. I'm a firm believer that it could work and will work, plus it will naturally neutralise bacteria from the water therefore purifying it in a sense because of the heat that it will introduce and infuse into the water. What do you think about all this?

[@deniseward002]

Can we boil water 20 lit. At least.. How much time required

[@Fritz_Schlunder]

It takes about 628 Watt hours of thermal energy to boil away one liter of liquid water, assuming negligible thermal heat loss from the apparatus, and no heating of the resulting steam beyond 100 degrees Celsius, when the water has already been pre-heated to 100 degrees Celsius liquid state. The size of the Fresnel lens in the video appears to be roughly 1 square meter, and when oriented directly perpendicular to the sun without atmospheric occlusions like clouds, can collect approximately 1000 Watts per square meter of lens area (although not at sunrise or sunset, when the sun is too low on the horizon and must pass through too much thickness of atmosphere). In other words, he appears to have an approximately 1000 Watt optical heater. If the thermal energy was used with 100% efficiency to convert the liquid water into wet steam, then he could theoretically boil off approximately 1.6 liters per hour (ex: 1000 W / 628 Wh/liter = 1.6 liters/hour), or 12.5 hours of strong sunshine to boil 20 liters. In practice, there is some additional energy needed to raise the water from room temperature to 100 degrees Celsius, there will be some optical loss due to reflections, and there will be substantial heat loss due to maintaining the boiling pot at 100 degrees Celsius (unless well insulated). Consequently, it is more realistic to assume 50% overall process efficiency (or less, so at least 25 hours of strong sun to fully boil off the 20 liters of water, using the apparatus shown in the video). If your goal is sea water desalination, it is much more efficient to use reverse osmosis membranes and an electric pump. Reverse osmosis sea water desalination can be done with about 1/1000th of the energy requirement, compared to simple boiling at 100 Celsius (without heat recovery/recycling of condensate heat). Photovoltaic solar panels for generating the electrical energy needed for running an electric pump required for reverse osmosis desalination, are around 20% efficient, but this still means that one can produce over 200 times as much clean water per unit time, for a given solar energy collection surface area, compared to direct boiling of the water (without heat recovery/recycling of condensate heat). Solar thermal heating of things (like making domestic water for taking hot showers) is fairly practical (although it fails to produce on cold cloudy days, when homeowners want the heat the most). Solar thermal energy is not very practical for desalination of sea water. Reverse osmosis desalination powered by solar photovoltaic panels is however quite practical, but the water produced is still more expensive than "free" water that falls out of the sky as rain and snow, and collects naturally in rivers and lakes. Common households in coastal areas should anticipate spending roughly $20 extra per month on residential water (2023 prices), if the household was entirely being supplied with desalinated sea water (via reverse osmosis + solar photovoltaic panels), rather than "free" water that falls out the sky as precipitation.

@@seahawks1185 same place we got ours, our MINDS.

[@henryhewitt1571]

They built the pyramids with disaggregated limestone, then added a few percent of cement and poured concrete into forms. In this way, perfect joints are unavoidable. Quarrying, chiseling and levitating cannot possibly get joints even close. (See Davidovits.) However, the granite was probably melted first then poured into forms to make boxes and the structures like the ones in the King's Chamber. Hathor's headdress probably held a lens that melted the granite. Not sure how else you could do it. They surely didn't lift 1000 ton blocks of granite. With focused sunlight, there is no need for aliens or giants (or Egyptologists).

[@mamaboocee]

@@henryhewitt1571 wow. That's a good concept. I always thought they used water displacement to move the blocks but as far as the joints being so almost perfect, your conclusion makes sense. Have you ever heard of Coral Castle near Homestead, Florida? Look in to it, the man man who quarried and moved huge blocks of coral did it all by himself- and I think the ancient Egyptians used similar practices.

[@henryhewitt1571]

@@mamaboocee Thanks, I'll check that out. As for Giza though there is also the time issue which adds weight to the cement case. Starting at each corner with 2 crews of 20 year old boys (maybe 3 at each spot) going different directions, and a pack of others hefting up baskets of mix, and of course a crew disaggregating the local limestone, just down the hill (the stuff on top was too hard, like the Sphinxes head apparently) where they also keep the water, working only at night (it gets hot there I guess), by pouring one 2.5 ton block every 20 minutes, ie, 3 per hour and a 12 hour shift, that's 36 blocks per crew per day. So 8 x 36 = 288 blocks in a day. That would be 8,500 blocks or so per month and if it took 20 years, as Herodotus says, or 240 months, you can built a 2 million block pyramid in the time suggested. It would take a million years to bang away with copper chisels and you still would have crummy joints. Eliminate the impossible and voila -- Giza. Even if a 6 hours shift was all you can expect, doubling the size of the crew does not overwhelm the site of the encampment locally thought to accommodate only a few thousand workers. 100,000 slaves getting whipped up a ramp that contained more material than the pyramid itself is not only insulting to the locals at that time but it indicates a lack of awareness on the part of those who make such absurd claims.

[@jesselam5867]

@@alexriddles492 Or even a better idea, you use both a boiler and solar, you have a glass enclosed flask that is double walled for more efficiency, and to prevent the solar cell from melting. And because the glass is transparent, the UV rays will be able pass though to the bottom of the flask where there will be a solar panel. So the boiler will convert the infrared to electricity, and the solar will convert the UV to electricity. The end result is a much better utilized system that can capture energy from the sun, what may potentially produce more electricity.

In high dry ground, 7. feet below the ground, the aver. temp're was 20 deg. Celsius (?)- so burying a copper or stainless tube in such depth, you can extract its free natural heat- to augment your existing house heating system... Youll put a circulating water inside such coil design, buried tube, your water pump will forced the said water to pass thru a heat radiator with blower... Thus, the water heat contents will be transferred to the house interior atmosphere- continiously, 24/7 basis... Thermos wall ( double wall metal, with built. in vacuum motor) will keep the interior temp're of your house constantly- for 7-14 days period, before needing a re. heating in winter or air. con running during summer time... Why such thermos wall technology is never tested for housing in desserted area of middle east- is a big question mark...

You could use this to heat a room in the winter. Get one of those pizza stones for in the oven and put it on a metal table and put the fresnel lens in a window with lots of winter sun. Put the stone a little further away from the focal point so that you don't melt the stone, but close enough that you can get the stone heated to a few hundred degrees so it throws off heat.

[@DesertOwlForge]

RE the end, yep that's Florida all right. More seriously, awesome build! No fuel forging is an awesome idea. Though I think this is too powerful for steam as the boiler might melt!

I wonder how much Portland cement a person could make in an 8-hour day with the fresnel heating the limestones, and then smashing them with a steam hammer, also powered with the fresnel? Or automate the entire process, with a hopper feeding limestones into the furnace and through a crusher. These could be a perfect solution for building cement/stone buildings using locally-sourced materials in remote locations where it would be difficult or too expensive to ship the cement! Fantastic work, Dan!

The extra at the end was awesome, flat tire on the trailer, funny

[@martiniafg]

melted glass sphere looks amazing!

[@leroyrowe93]

wow you made a glass/steel alloy, if you can call it that. great work on material science

[@middleway1885]

Bah... more episodes, please~! Hope you and your loved ones are doing well... onto the next episode!!

Amazing amount of concentrated heat! If you haven't already, you should build a knife or sword or axe. Thanks! LS

That is a top-notch tracking system! With a high enough precision fresnel sheet, I wonder if it could be a light-weight alternative to traditional parabolic mirror telescopes.

Crescent Dunes Molten Salt Solar Thermal Power Plant - Crescent Dunes is similar to a conventional concentrating solar power (CSP) system, using thousands of special mirrors called heliostats to focus solar energy on a central tower. The difference is the use of molten salt, which flows through receiver panels at the top of the tower, consisting of alloy tubes. That enables salt to double as both an energy transfer and an energy storage mechanism.
