@@katamuski Sí, muy bien! Tengo mucho horas magnificas con la violina!

@walp86 muchas gracias por responder!!! Este será mi segundo violin!!! El primero es un violín muy básico pero con el me enamore de este instrumento así que hay que avanzar!!! Un saludo desde España 🌻🌻🌻

@@katamuski Sí, claro! Tengo tres violinas, una violina por pequeño dineros pero muy cansado, hecho en china, una violina allegra, que cuesta no pequeño pero no mucho dineros, hecho en china pero ancenstro aleman, y una violina excellente (Stentor Verona) hecho en china pero con ancestro albion. Viva la musica! :)

@@alelys66 No, this model will stop at around +7°C air temperature.

@@monikamalling3220 Good Question! 1.5V x 4 = 6V original, 4 pieces of AA batteries. 9V emergency battery is placed in parallel connection, which voltage is greater than the required 6V, so Yes, it should work. I will try, to validate it however!

Hello! I will build a much bigger heat reservoir, and "submerge" it in the ground. The only problem is the enormous amount of insulation required, that costs thousands of dollars :(

Not at all use sand on outside of drum also roughly about 1 in then rest of it with r30 insulation

Okay, I will do the math on the R30 amount required!

@@jrgenj.7604 Hei! Takk! :) 3drobban.se/produkt/thermacell-adaptern/ er en svensk hjemside som salufør ein similar adaptor! Spörsmål om frakt til Noreg? Anners kan dere skaffa Tradera, (Svensk auktionsapp) og købe via den om du først spörsmåler salgaren om frakt til Noreg! :)

@@vladimus9749 Yes, of course! :) A sand battery is a thermal storage that is ment to be used later on. In this case, I heat the gravel up to 550°C (maximum heat gun temperature), but since I only have 2"/5cm insulation, the temperature "only" reaches 250-300°C. In Sweden, where I live, you sometimes get paid when the electricity-prices are negative, that's when I am going to heat my future enormous sand battery (15m/45' × 2m/6' diameter). I also have a LOT of solar panels, which over produces during the summer. The final version of the sand battery will store about 10000-15000 kWh during the summer, which will be pumped into our house during the fall/winter. :)

@@walp86 Thank you. Why were you heating the gravel through the long insulated pipe instead of directly?

Direct heating with element, wire, or stove-spiral, is of course better, BUT, when you eventually have 75 tons of sand in the battery, 6 ft down, you don't want to change direct heating elements when they fail... that's why a heat gun-solution is better, since you can replace them within seconds. :) The pipe is required to spread the heat evenly, and spare the heat gun from air restriction/overheating problems.

Makes sense. Subscribed and looking forward to tracking progress.

Use a dry vent element there $13 and you can blow air over it thats best way i found so far

Okay! Check out my second sand battery concept video, you will need a LOT of insulation since the sand temperature can get many several hundred degrees Celcius/Fahrenheit. The DeltaT gets enormous... In my final test, I will use longer pipes, more sand mass, and a LOT of insulation. :) m.th-cam.com/video/oxTrxSElmPE/w-d-xo.html

@@ductaobui2402 Yes, it is a bit leaky, but works once you understand how to apply the correct pressure :)

@jsd21hb Hi there! In this first simple/small scale test I just wanted to see how easy/efficient different heating methods were. I have made a new, bigger scale 24h test which I will upload here tonight. th-cam.com/video/oxTrxSElmPE/w-d-xo.htmlsi=QGbb8kggciukRri3 The final version, which will heat our house during the winter, is ment to be over 45 ft long, and over 7 ft in diameter, and will be insulated with enormous amounts of rockwool insulation! :)

@@TimBorg Yes, I will buy another one soon, because they are so awesome!! :)

@@walp86 me too I need to get the long range version E+

Just bought one, love it!

@@dangerousdoggo5465 Nice! I have Volvo XC40 67 kWh, but will buy an almost new 62kWh leaf soon! :)

@@walp86 That is good! I have a volvo S60 2.4 turbo AWD, got the nissan because it's 1/10 the price for "fuel" and pretty much no maintenance! Love the car! Love the volvo too! How is the electric volvo?

@@tornikechitadze20 Wow! Melt da shit out of it! X)

@@richardjcote9854 Hi! I bought mine from "Swedish Tradera" (search for thermacell adapter), but it is readily available everywhere, here in Sweden. Have a nice day! :) MVH

Hej! Jag köpte min från tradera (sök efter thermacell adapter) I bought mine from tradera (search for thermacell adapter) MVH

Hello! Thank you! No, it will not work in practice, because people can die from Legionnaires' disease!! (The water needs to be above 55-60°C) It will work in theory though, if it hot enough outside it will reach 41-43°C! (+10°C outside or warmer) however, YOU WILL GET B. LEGIONELLA AND THAT IS REALLY DANGEROUS!!! People can die! Or get very-very-ill!!

@@walp86 thanks so much. No 43 degrees is not a high enough temperature. Thanks for your video.

I think it is 195 km/h (original top speed, electronically limited)

@@walp86 That can be removed :) i have 2006 V50 1.6d Stage 1 but i never try max speed :)

Nej, men har en bypass ledig, blir vattenflödet för högt kanske, och därför så isar förångaren igen?

Trevligt! Jag har en Pico 5R 5kW nu, som dock djävlas... kanske blir en tredje minipoolvärmepump inom kort :')

This is how you use the 9V-battery method: th-cam.com/video/6MAieLRFp0I/w-d-xo.htmlsi=oReCnwHOHUP29oFW

Hej! Det beror på, den funkar bra på senvår, sommar, tidig höst, för mindre pooler upp till 5 m³, men såfort det blir för kallt ute, så får den problem att hålla tempen, har för mig att det var vid +7°C...(?) 800 L är dock "lite", så det blir bra sålänge det är "varmt" ute :)

Hej! F730 och speciellt F750 går att få tag i billigt på blocket, då många river ut sina "besvikna" system i förtid. Vad har du för budget? Och hur stort är huset? Var ligger det? Ålder på huset? Antal boenden? Nuvarande förbrukning? Har du bra "klimatskal", dvs är huset lufttätt? :)

Nice! If you get the " frozen problem ", just heat it! (Check my other video for that solution!) :) th-cam.com/video/CEp2Za5IclY/w-d-xo.htmlsi=WXHrtvfumWkxZUL3

@@walp86thanks 😍 good job!

Yes! One might think that it is contraproductive to burn a bit of energy here and there, like this, but the dreaded and unnecessary long defrosts costs hundreds of dollars per year. So this is a rather cleaver solution! =)

Nice! I have the same idea! I'm gonna construct an aluminum frame roof, and put two 395W panels ontop, its gonna be a bumpy ride...it might as well become a submarine...

Hi! What do you mean?

@@walp86 can you give me you mail for contact?

@@walp86 that i talk details

@@walp86 Hello sir. I am a Digital marketer. I have seen all your videos, your video quality is very good, but your videos have very few views and likes, do you want to increase the views, likes, comments and subscribers on your videos? Do you want to promote your TH-cam channel?

Yes, you are correct! I thougt that fact was evident when I showed the miniscule light output of the light bulb :) My friends question was more of a will they work from "0 to 1" :)

​@@walp86okay makes sense. but you can tell him that you loose at least 50% efficiency with these polycarbonate sheets. Even with a single layer of clear glass you would probably loose around 30%

Yes, the range is only 100m (328 ft.) under optimal laboratory conditions. I had trouble pinging through my car window, but I must say that my SmartTag2 pings more often than the SmartTag1! I think that these products are mainly for people who live in densly populated areas, like South Korea, Japan, and Supercities in The US. :(

Yes, ozone smells quite similar to household chlorine bleach, (sodium hypochlorite). The half life of ozone is 8-30 minutes in real life situations/spaces, and as a rule of thumb, 10 half lives is 1/1024, (i.e ~1‰ remains), however, since i waited about half of that (4 to 10 half lives, depending on ventilation etc.), and still smelled the "chlorine bleach", one should be aware that it might take up to a full day, to get rid of it all! :)

Thank you :) Please subscribe to my channel for more info! Yes! But take note, that the more snow it chews, you have to push harder and harder on the handle! I weigh 200 lbs/91kg, and manage to do it without problem, unless the snow is wet... that is the weakness of this machine;thick wet snow! :(

@@walp86 Thx for the info! I'm at 96 kg and 183 cm. So I think I can handle it. :-) I'm aware of the limits of the machine. But after all, what can one expect from a NOK 1399 item? :-)
