Pool heaters are complicated. One must
circulate the water, attach in line heaters
etc. etc. And where is the spectacle?
The Naked Flame Pool Heater consists of
gas lines along the bottom of the pool.
There is an air intake along the gas line,
and so on emerging from the line there is
a mix of gas and air. This is ignited as it
leaves through valves in the gas line.
The result: spectacular underwater
flames and bubbles, which can be
appreciatively oogled during poolside
coktail parties, and which render the
water
nice and warm in case anyone wants to
take a postparty dip. Turn off the flames
first.

so you can't be in the pool while the heater
is on? also, how does developing a system
for heating the pool through underwater
flames get less complicated than standard
pool heaters? |
|
| |
You can be in the pool as long as you don't get too close. Sounds neat, but much of the hot exhaust is wasted by bubbling on the surface. |
|
| |
you just invented the "bungston burner" -
a natural winner + |
|
| |
Complex, inefficient and looks stunning. What's not to bun? |
|

//Complex, inefficient and looks stunning.// Reminds you of anyone? |
|
| |
Can't be me, I'm efficient. |
|
| |
Anything that includes "Naked" and "Pool" is generally worthy of a bun. |
|
| |
My old flame's pretty hot, but I don't know if she's up to heating a whole pool. |
|
| |
You might set this in a separate glassed in compartment, and circulate the water as it rises, for safety reasons. I don't think the heating would be very even though. |
|
| |
you know, if you used radioactivity for
heating, there would be no need for gas,
and the water would glow an eery blue
color. heavy water and lead swimwear
would need to be utilized, but those are
minor issues. |
|
| |
/much of the hot exhaust is wasted by
bubbling on the surface/ - I thought
that those bubbles would probably be
pretty cool by the time they made it to
the top. |
|
| |
Agreed. The heat exchange would be good, especially if you could encourage smaller bubbles to form. The fundamental inefficiency lies in using high grade fuel to produce low grade heat, but I gather people already use electricity and gas to heat pools (shudder) (+). |
|
| |
What's the substance that ignites when it touches water? |
|
| |
Sodium metal ignites on contact with water. However, it leaves sodium hydroxide as a by-product. |
|
| |
It tends to explode, rather than burn. <link> for movies. [+] |
|
| |
I like this idea. Some kind of very fine wire mesh above the flames would (a) stop people sticking their toes into the flames and getting burnt, and (b) break the bubbles up into smaller bubbles which would lose their heat more efficiently to the water (having a greater ratio of surface area to volume). |
|
| |
So the tube at the bottom of the pool has a mixture of fuel and air? Kind of an explosive hazard. |
|
| |
But still this deserves a good bunning. |
|
| |
I'm not positive but I think that this will not work the way you think. You will get flame and lots of bubbles, but the flames will be very small and very intense. You will also need very high pressure oxygen, and as stated the mixture needed to sustain the reaction is Very Explosive. |
|
| |
And the pool water would be saturated with CO2... |
|
| |
The air line could be separate from the gas line, and they could meet in a small combustion chamber at the bottom of the pool. This would reduce the amount of gas/air mix lying around waiting to explode. |
|
| |
The marketing information we received was not clear on this point. I think BUNGCO Reserach and Design developed it and they are going to license the technology.
I suspect the halfbakery is being used as a focus group by BUNGCO executives (the cheap bastards). |
|
| |
Gas as we know is dangerous (and a fossil fuel) so is bad... |
|
| |
Good clean arc welders will be brighter and less dangerous --- just make sure you wear sun glasses... |

"The water looks too cold for me, [madness]. You go first" |
|
| |
This makes me wonder if it is possible to light farts under water. |
|
| |
Hot water and bubbles.. isnt this a hot tub? As long as your significant other is away you can add and "old flame" to the hot tub. |
