  1. I am planing to do this as a college project is there any way that I can contact you

  2. Hi, I have some rusty classics cars that I’m working on and have tried various usual things to remove surface rust, chemical and mechanical.
    Tried needle gun, Sandblaster, sandpaper but the best and most tidy thing so far (but slow) is a vibrating engraving tool. I works great for small patches.
    I was sort of hoping someone like you would try an ultrasonic device like your soldering iron but with a hard pointed tip or several pointed tips similar to a needle gun or an ultrasonic wire brush with thick solid bristles.

  3. Hello Ben. I seen many of Your vids and wondered if You could try attempting to liquify radon gas from atmosphere . My idea is it could be used as welding gas (for automatic welding). It is bit crazy idea but You seem to have enough common sense to do it.
    Main goal of the experiment wold be figuring out ballparks - how much radon can one get, how much power is needed to overcome it's decay.
    There are places on earth, like former uranium mines where You can get really loads od radon. Even more can be obtained via fracking in such places.

    As welding gases become more and more scarce resource, radon could help gas-hungry automated welding operations to be not pushed into "well, it was possible before ww2" type of talk


    1. Hi Ben,
      Soldering dissimilar materials has always been a challenge. On in particular is the joining of carbon/graphitic materials to metals/ceramics and maintain an electrical conductivity. The commercial materials to do this seem to be low temp solders with trace transition metal content. Any thoughts on this method or a DIY version of these alloys?
      Hope you and your family are all staying healthy and well.

  4. Greetings, Ben! As a recommendation from another commenter, I'm seeking your thoughts on whether I should pursue some accidental findings regarding graphene production or it's just a side effect of two chemicals that 'look cool'. I have a quick and dirty, unedited youtube clip here https://www.youtube.com/watch?v=oJqCuKV35vM and honestly it was just a side effect of something else I am pursuing, UHTC and graphite with other components for aerospace applications. If this is of some merit, I wouldn't mind discussing what else is in the concoction, though at present I'm keeping the specific formula close to the vest as this other product may evolve into a commercial application.
