  2. Very intelligent production way.

  3. this tube is made in China. not US

  4. It made in China

  5. Fascinating production process. Somewhat reminds me a long narrow,
    “Thermos” jug. See – .thermos.com/history.aspx

  6. A wall with vacuum tubes backed by salt and a lens focusing the sun and a
    mirror (or micro lens ) behind the wall arranged similarly with vacuum
    tubes and salt producing from a water boiler stem to drive a tesla
    bladeless turbine and a dc electrical motor ? Totally doable ..RIght ?! Dr.?

  7. Not sure I understand the application of such a vacuum flask as a boiler.
    In order to use the steam, it has to be under pressure. It’s the pressure
    which drives a piston, which turns a generator shaft. However, you say in
    the video you can’t put the lid on the flask because it’ll just turn into a
    bomb (presumably from the pressure build-up. What use is such a glass
    container that can’t withstand useful pressure? Boilers may lose heat
    (though professional ones are also insulated) but they are made out of
    metal so they can withstand high pressure, which is what they essentially
    output for energy. Am I missing something?

  9. I Suggest you make a pair of Variable cross polarized sunglasses.Before you
    damage your retinas if you haven’t already

  12. DID ANYONE NOTICE THE SASQUATCH BEHIND THE BUSHES???? AMAZING !!

  13. This concept, applied to water heaters, could make you a lot of money. Get
    a patent. 

    By Greg Dubela on Sep 30, 2014

  14. you are a proper nerd, keep it up.

    By rainerfilm on Sep 30, 2014

  15. Could you implement this concept to make a “Steam Engine” for producing
    electricity? 

    By jacob smith on Sep 30, 2014

  16. .
    wouldn’t this degrade the integrity of the “glass” and cause more molecules
    than normal to be consumed when used for beverages after a test like this?

  17. can you desalinate saltwater or seawater?

  18. most worthy mate , big thank-you for sharing

  20. it is possible to get steel iron glowing hot??? iam a blacksmith and
    buring material i expensive if i can use the sun that is free it would be
    great

  21. been thinking about using this as a replacement for nuclear power since
    like 2001, nice to see a proof of concept, never thought of steel wool! I
    strongly encourage anybody with the wherewithall to find a turbine and an
    alternator ;)

  22. @Dan

    Have you tried this with copper wool?

    If I am reading this chart I found correctly:
    http://www.engineeringtoolbox.com/thermal-conductivity-d_429.html

    Then the copper wool, that you should also be able to find in any given
    super market as well, might serve to a much more powerful and immediate
    ends.

  23. Hi Dan. So far I love all your videos. There’s always some good info in
    them.
    You mentioned the stores putting candles under the tea maker. I think that,
    if nothing else, they’re getting people to buy the candles which pumps up
    their sales volume.
    Keep it up. I love this stuff. I wish I had your resources.

  24. Great videos! Tks I got new ideas now. ;-)

  25. The water boils rapidly because your only heating a small fraction of the
    water, the water nearest the glass. For a given volume and radiant energy,
    the Chinese tubes are probably more absorptive of the sun’s rays while not
    concurrently having to heat the steel wool which caries much less thermal
    energy than water.

  26. Oh I love these glass jar experiments.

  27. 4:50 What a daring way to test if something is hot. Grab it with the palm
    of your right hand first!

  28. Impressive, cant wait to see steam boiler built

  30. Can a Fresnel lens be used to generate enough steam to run a generator and
    generate a useful amount of electricity?

    By raid517 on Oct 1, 2014

  31. i now know why they are chemtrailing the skies. its to stop DAN and his
    lenses from melting to the earths core. ^^
