So, pretty similar to the technology pictured in my link to the original Hot Water Sleeping Bag idea? |
|
|
[-] For less weight, bulk and cost, you could simply get a thicker sleeping bag which would keep you however warm as you wanted to be... and without the risk of getting scalded. |
|
|
It's stupidly impractical, and therefore perfectly halfbaked. I like it a lot + |
|
|
[marked-for-deletion] it's a copy of the other one, come on. |
|
|
It's different. The other one is no good, but this one is ok. |
|
|
Far from it, flyingtoaster. The other one has no
continuous-flow heat engine. |
|
|
[jurist], yes the technology is virtually the same.
However, in the hot tub version, the methods of
control lie in the heat of the fire, only. There is no
closed heating fluid, essentially, since the hot tub
water *is* the fluid. |
|
|
In this device, you can open and close valves
between the boiler and the bag to adjust the
amount of steam that escapes the boiler and thus
control
the heat inside your blanket. There could be a
release valve to the surroundings right near the
bag, too. This would allow for user control next to
the bag, and would also steam the tent (or not if
you put the sparger outside the tent). |

What a good idea ,I never would of it!!! |
|
|
yeah, something an 11 year old could invent! |
|
|
Shouldn't this be under product:device:torture and renamed "Waterbedding"? |
