    Lithium Gas: Solid to Gas Conversion Processes?

    What is lithium gas? Lithium is a solid metal (At room temp). Is lithium gas super heated Lithium in gasious form? or is there a process other than heating that produces Lithium in gas form? Is there a chemical way of converting Lithum to gas form? Thanks Jim

    Ideas for Robot following a path

    Yes...lol. I posted something on it. (before I realized that it was forbidden.) The PMM machine is one that has been tripping me up for years. I've never put the raw time into the long form calculations. (probably no longer have the skills to do it. It's been awhile since school) What was...

    Are Airships Making a Comeback for Cargo Transport?

    That was one of my thoughts, that these were fair weather only ships. I don't think they have resolved that problem since it is fairly inherint to the concept of lighter than air designs. I would think that even a strong wind would extremely limit the control of an Airship.

    Are Airships Making a Comeback for Cargo Transport?

    Has anyone seen the recent new in the last couple of years about the comeback potential of the Zeppelins or Airships? There seems to be a good argument about the efficiency of these ships in regards to cargo transport. I can see the environmental impact and perhaps the construction costs and...

    Ideas for Robot following a path

    I've seen something like this. THe robot I saw had a spinning arm on top that would knock stuff over that just spun all the time with a counterweight. THe robot also had a light sensor that would run above the ground and detect he reflection of the ground vs the tape. In this instance the...

    Is a Self-Contained Generator Project Feasible for Sustainable Energy?

    The second machine would be a duplicate of the first and just be opposite cycle.

    Is a Self-Contained Generator Project Feasible for Sustainable Energy?

    I'm looking to subsidize the power to my house. If it would create enough surplus I would get off the grid completely. Jim

    How Can I Weld Aluminum Foil Without Melting It?

    You could also experiment with soldering the foil sheets together. I would use a propane torch and cover the sheet seems with flux (extending it out from the seem a bit) and melt solder over the seem and drop the solder onto the seem. The residual heat from the liquid solder should bond the foil...

    How Can I Weld Aluminum Foil Without Melting It?

    I also remember seeing thin sheet metals (back in the 1930's) being welded together using a powder burn process where you used a flux (plumbing pipe flux) mixed with bonding metal powder (same metal as the sheets) and magnesium powder. The mix would have to be experimented with to get it...

    How Can I Weld Aluminum Foil Without Melting It?

    I don't know your application or the thickness of your foil. But if it is standard kitchen foil, I would use the heavy duty stuff. (the thicker the better) Also I would look into polymers to bond the foil sheets together. If you are passing an electrical current through it and are concerned...

    How Can I Weld Aluminum Foil Without Melting It?

    No, unfortunately it was a long time ago in a pilot program in high school. But I did assist with the actual welding of foil. I remember the unit used was also used on making ciurcut boards. (the old way, where you used soldier sheets and placed them on green board.) The tracing compond was...

    Understanding Molecule Theory: Tips and Tricks for Hands-On Physics Enthusiasts

    Being an aftermath generation of the Star wars/Star trek era, I have always wondered (since high school where I learned the principal operations of a turbine engine) If it was possible to compress the molecular structure of gas partials electro magnetically (possibly acting on charged...

    Understanding Molecule Theory: Tips and Tricks for Hands-On Physics Enthusiasts

    So would it be possible to compress a gas molecule through a series of compression acts? Then later release that compression rapidly? Perhaps I do not know the fundamentals of how molecules work. But would they rapidly expand and produce a thrust effect?

    Is a Self-Contained Generator Project Feasible for Sustainable Energy?

    How do you mean the power produced will not be enough to raise the winch system? The winch system would be DC operated (similar to that of one used on a truck or Jeep) The falling mass could be any given amount of weight to drive the gear train and generator. My thought was that the load...

    Is a Self-Contained Generator Project Feasible for Sustainable Energy?

    Hi all. I have a pet project of mine I have been occasionally taking off the back burner for years. The recent hike in Electrical costs has really cheesed me off and has re-flourished my ambition for this project. It is a self contained generator. I know the very idea of it exposes me to...
