So cool!

the music was very dramatic

I remember watching this video so many years go!

25k BTUs is only 7.3 kWh. If the sunlight strikes the ground with 1kW per M^2 (10.7 sq ft) and you have 32 sq ft then you should be getting closer to 3 kW. If we call it 40% efficient, then 1.2kW and call it 6 hours of good sun in the summer. That's about your stated 7.3 kWh.

That was an awesome upload

Gran video, muy ilustrativo. Enhorabuena. Viva Brazil

Awesome panel, lot of work pays off!!😇😁

That's freedom

Merci prof de sciences de nous avoir autorisé

Merci Grace à toi je peux utiliser mon téléphone en cours 🙏

I was a little concerned about the mixed reviews, but I used it last year and hooked it up again this year and it was great ruclips.net/user/postUgkx-izdrK3eF-HMvjzeBOxToD6Fx-4ulJUh . I couldn't get my 10' Intex pool above 76 degrees the year prior and last year I got it to 90 and had to put ice in it. This worked so well! I have just 1 mat hooked up to a 1,000 GPH Intex pump and it makes a significant reduction in the flow rate coming back into the pool, but that is to be expected with how far the water has to travel through the mat.

In Japanese it’s called “nemuri gusa” meaning sleeping grass, or “ojigiso” meaning bowing plant ❤

*EXPENSIVE* to build today.

Lovely piece of work ... As you heated the thin copper sheet to solder it to the tubing & it oxidised to black .., think I would have ignored the painting & just " washed " over the back of the sheet with the blow torch to ensure all was oxidised black ...

Ah you speak my language and measuring standards too...wonderful 🇬🇧

Wow !!!

A little more informative please the information really helps

Thank you for filming and sharing

Putem crestere la 20 grade de frig??

A roll of black polyethylene pipe in the sun would do the same thing.

I say skip the soldered joints as much as possible, skip the headers and the tiny diameter tube and use 1/2" OD soft copper coil in 100 foot rolls then you only have one solder joint between each 100' roll and one at each end to connection to a threaded connection and you have one long copper tube with only one joint and ultra low chances of leaks. No cutting individual tube all you need to do is straighten the tubing and use a hand pipe bender to quickly and easily form 90 deg corners. In the video he did 21 pieces 3/8" OD @ 90" long = 157.5" so using 200 feet of 1/2" soft copper is longer and larger in diameter giving much more surface area for heat transfer. Also the side of the copper transfer sheet with the tubes soldered to it should have the tubes facing the sun as each 3/8" tube is bathed in radiant energy(higher surface area in the sunlight) in addition to the copper sheet from the sun vs the way it was done in the video where a very small point (round tube sitting on flat sheet) where there is direct heat transfer through the soldered connection.

lap lap life 💪💪

Try making connections in series. In refrigeration we use pressurized gases . So doesn't make different in parallel tubing but in solar heating it makes lots of difference because we use principles of hot water lighter than cold water and always needs to be extracted from top only.

... just my two cents ...but the plant likes to get trimmed back too ... just keep it warm ... all movement stops with the temps below 62*

OMG a 14 year old video 🤯

This was made ten years ago and you still use lead solder? Why not braze it with what is used now in water systems, and also for refrigerant systems.

I have a lot of heat in the attic from the corrugated sheeting on the house because there are few splits placed only for mechanical resistance and a lot of heat is transferred from the sheeting to the attic.. Even in winter when there is a little sun, it heats up up in the attic and I didn't know how to transfer heat from top to bottom. A solution for the summer can only be the following. Copper pipes can be installed through the grids of the sheet metal on the house, through which the water may circulate at some distance from the sheet metal on the roof. On the entire surface of the roof, a lot of caloric energy is lost and transferred to the attic. It can be transferred to a heat engine or a steam engine that produces free electricity and hot water only in summer. In winter, it is more complicated to recover heat because the water freezes. Used possibly antifreeze ..... The electrovoltaic panels are fragile, expensive and with a .......larger hail.......it certainly won't last.....Anyway, I don't have enough money for something like that. There are many houses and fences with corrugated iron dissipates heat from the sun, heat that can be used... With the 0.5 mm sheet we have a large transfer of heat in the attic. It is logical that with the 0.2 mm sheet the yield should be higher... They can be oriented according to sun using electronic systems for maximum yield.

I grew up with this plant in South Africa. Childhood memories 💕

2022. It will there soon.

It's the plant spirit protecting all that precious DMT. 😄😵‍💫🤯

why are they corresing the plants 😭😭😭

This plant brings so many of my childhood memories back in Guatemala. When my dad first showed this plant to us he said, "wanna see a magic trick?" and he proceded to touch it while saying "muévete, muévete" -which translates to "move, move" in english-. My brother and I were mesmerized by the power my dad had over plants hahah (he´s an agricultural engineer, which just made so much sense haha). Even now when I see this plant, I´ve to say "muévete, muévete" to feel like I have permission to touch it. <3.

I REALLY need to talk to you about the progress of this project 11 years later as I am looking to do something almost identical in the UK.

SOUNDS JUST LIKE LARRY HAUN----- SPOOKIE.

It goes my millions of names

did you ever get startlink?

i come bake and watch your videos every so often. would really love to see you publish some updates

Does it say buildings in this version?

STOP BULLYING IT

Joe, should show this to vegans!!🤣🤣🤣😉

That's brilliant idea, to have a sheet on top of copper tubes to distribute heat evenly and very effectively.

Copper is too expensive for that project aluminum conduit would be better and heats up faster

Cooler us rmtii expensive
