INSTANTANEOUS SOLAR WATER HEATER HOT WATER

Jacaranda MUSIC From Garageband on the Mac.
This video was shot on a cold Florida Day. 46F. The water was 56F. and reached a source temperature of 135F. After the 2 feet drop and outdoor leaching the collecting temperature was 97F.

The purpose of this video is to illustrate how a fine mist can create some instant steam and hot water. If the flow was .25 of this, solid steam would result. Too fine of a stream and the Leidenfrost Effect would prevent proper absorption. I will do a video illustrating the effect soon.

This is an alternative idea for more efficient steam production. You gain the small SPI of the hose and flash steam volume. This would need to be modified to do that. Video on that soon too I hope:-)

I have a convex mirror, can I make cold water?

[leafs11cups]

What is your point?? Yes copper is a great conductor with the suns heat, you warmed up a glass of water.......try running you house on this....

[Dubconferencedotorg]

very cool

Nice video and music...(and morse code)

Ok crap, need to correct my numbers.

The water from your tap is about 70f, not 40f, so that makes about a 30% difference. Still, this means you'd save around $630 per year.

Additionally, since water from the tap is 70f, the solar heater can actually heat it ~30% faster than the calculation above. I just used 40f because that's what he had in the video.

It really depens on what the temperature is for your tap water. The colder it is the more heat you need...

@hermenutic

The water heater probably ends up being the single most expensive thing in a house. If you replaced it with 12ft by 3feet of parabolic mirror like I said above, plus what you need to vaccuum seal it, you'd save like $900 per year in electricity bill savings.

@hermenutic

If you had a parabolic trough mirror about a meter across the curve, by 3.6 meters long, and you had it focused on a copper pipe vaccum insulated, you should be able to heat 80 gallons of water from 40f to 140f during the 6 hours of optimum sun....This is based on rough calculations I did assuming 1/3rd of the solar flux is reflected by the earth's atmosphere and 2/3rds would hit the mirror...

It takes about 70560000 joules (19.6kw/hr) = like $2.55 electric bill.

@imatelly this is exactly what we do and it has saved allot of money.

[eldrama2]

this heat-on-demand is the way to go. is that a copper pipe? what other metals can be used that would be safe for drinking?

[imatelly]

great idea,but i think it will take people chainging there lifestyle slower to get them to like this stuff,how about turning your hot water off when not useing hot water and on 30 min befor u need hot water

[kimmer6]

Nice. But I can piss 9 gallons per hour. A parabolic reflector should be treated like a pistol. You need to carefully observe the background to limit collateral damage. A glass paperweight on the windowsill once set my girlfriend's computer desk on fire.

I was reloading the hummingbird feeder and saw a newspaper burst into flame. Luckily I had a 9 gallon fire extinguisher on me....

I see that this works with a small volume of water flow. I do not see how it will heat hot water for a family. I am favorably impressed with the ability to harvest the sun in this way.

I would be interest in how long it takes to heat 80 gallons of water such as a household would use.
