Digital Camera Down

My battery is down, so I'm recharging it so I can show some pics of the IKEA thermos.

IKEA Flask (Update)

I just got my IKEA flask this evening. So, I will be taking some pics of it sometime tomorrow and hopefully cutting on it too. It is an interesting looking flask.

Does anyone see this as related to the heater?

Red-hot ice cube by induction heating - YouTube

Incandescence (photons) is a wave, just like heat is (infared) -- different speed/frequency....

Just thinking here.... Ignore if it doesn't make sense. I don't mean to derail anything here.

Good work,

I would just like to add the following images of a Joe Cell, known to use stainless steel

Thanks

Thanks for sharing that with us!!

I purchased some copper tube to start testing with these, the diameter is 1/4 wave of 60 hz is 125000 m as i am allowed by the harmonic math to multiply by 6 or 10 :

I'll go with 1.25*6 = 7.5 cm for the diameter

Hi Gordon,

What's the diameter of your cylinder?

this is how i think it works

http://en.wikipedia.org/wiki/Harmonic_series_(music)

Pitched musical instruments are often based on an approximate harmonic oscillator such as a string or a column of air, which oscillates at numerous frequencies simultaneously. At these resonant frequencies, waves travel in both directions along the string or air column, reinforcing and canceling each other to form standing waves. Interaction with the surrounding air causes audible sound waves, which travel away from the instrument. Because of the typical spacing of the resonances, these frequencies are mostly limited to integer multiples, or harmonics, of the lowest frequency, and such multiples form the harmonic series (see harmonic series (mathematics)).

The musical pitch of a note is usually perceived as the lowest partial present (the fundamental frequency), which may be the one created by vibration over the full length of the string or air column, or a higher harmonic chosen by the player. The musical timbre of a steady tone from such an instrument is determined by the relative strengths of each harmonic.

IKEA Flask Boiler Experiment (Sanding & Overview)

IKEA Flask Boiler Experiment (Sanding & Overview)

Overview:

Sanding:
Sanding is done only to the lower end of the flask. It's done on both the inside tube and outside tube. The edges of both tubes are sanded till they are very sharp with care taken to maintain the length of each tube at the same length. It's my understanding that both tubes are connected at the top by the screw on portion of the flask. So, nothing is done to the top other than adding the threaded bolt to the threaded part of the flask so the flask boiler can be hung into the water from a horizontal support.

Length of Tubes:
Inner & Outer tube length needs to be the same.

Gap:
Not to exceed 5mm but 5mm is okay.

Ring Support:
Needs to be very firm not allowing the ring to move.

Cutting Flask (Where to cut??)

Top of Flask:
Threaded end of flask, no cutting on top of flask!! You just need to fasten a bolt on the threaded part of the flask in a good way. Use your ingenuity. The bolt does not need to be welded to the flask. The thermos is suspended into the water by the bolt. That is the reason for the bolt. The flask is hung into the water from a horizontal support structure above the pail containing the water. Polycarbonate pieces can stand the water temperature really good, so you may use those in your construction process if you like.

Bottom of Flask:
All the round part of inner flask is cut off but no more!! The length of the inner and outer tube needs to be exactly the same!!

You need to purchase a Watt/Hr Meter with two decimal points such as the one in the pic below:

Diameter Query

Hi Gordon,

What's the diameter of your cylinder?

Best Regards,
Slovenia

for instance 60 hz 1/4 wavelength is : 1250000 meters
3/4 wavelength is : 3750000 meters
so the ring gap (using harmonic math ) should be 1.25 cm or .49 inches
height should 37.5 cm (can't really use 3.75 cm ) or 14.76 inch

you can reverse it too: 3.75 cm gap for a 12.5 cm height

Cutting Question

Hi Chet,

I'll let you know.

Cuban Hot Water Boiler:
I was talking to a chap from Cuba this afternoon, and guess what?? They've used a device made out of two cans one inside the other to heat water for years. It's called a poor man's water boiler. It's just used to heat water and not for heating. Anyway, the way the Cuban described it to me it resembles the thermos application very close except it's not stainless just tin cans. The Cubans put sticks between the two cans to keep them from touching and they were not tuned. He didn't remember which can was which from the polarity standpoint, but I thought it was worth mentioning.

Slovenia,
I can't see where to cut the thermos yet?
Once you get yours [hopefully tomorrow] perhaps you can make things clearer? [there is a seam 14mm up from the bottom??}

Thanks
Chet

PS
Duncan, My hope is that the heating will be so fast my granddaughter will be able to tell its OU!!
I will use it to warm her bottles,she is always in such a hurry ............[takes after Pop Pop!=}

super tektron .. sure any of us can change any thing to whatever now and get to the answer don't matter if'n its apples or pears

Here is the best desktop converter. it does energy conversions too, though the pic on the web site is from an earlier version. Very handy. I heard they use it on the ISS too. I use it all the time and for baking as well
