  1. Thanks. We are still at the stage where we are testing ideas. Then comes the development and refining. Creation, and building are the easy part. Funding is hard. Raising money is impossible
  2. I think a magnetic field would be the best. But I remember reading the ice ( frozen watee ), had superior lubrication properties. Steel on ice is very slippery, and can be self-regenerating
  3. I am interested too. I have not heard of EBC. But I was a truck driver for 23 years, all heavy trucks have some kind of engine braking. I wonder if there are any similarities?
  4. Dear Dr D, Thank you for the constructive advice. I agree with you. What I had in mind was waiting till days after the initial fires, when the ashes had cooled, and dried. Then vacuums would collect them and store them in sheds at strategic points. When forest fires erupted at later dates, special tanker trucks would be sent to the scene. Spray the materials at the base, and the area around, the smother the embers. I am pretty sure that lawn clippings and leaves that presently go to landfills now, can be burned to heat water, and rather than disposing of those ashes, we stockpile them.
  5. Free cad website It is actually free to download. But I found it on ebay, and paid the money for a physical CD. After I installed it, I learned that it is open sourced, and totally free to all. www.freecadweb.org
  6. Thanks to the advice from DrD, I finally found a program called FreeCAD. it cost $10, but it awesome, it has everything I want, everything I need, and more. The bad part is the heavy learning curve. I am not an engineer, haven't attended a class since 1987. I am following the tutorials now. Thanks for your help
  7. I don't understand why we fight forest fires mostly with water. The biggest advantages are that it is easy to pump, and store. It cools cools the fire, and is very easy to spray. But water is very heavy, often far from the fire, and evaporates quickly in heat. I am suggesting that we develop an ash collection system, similar to large leaf vacuums. Ash is light, and smothers fires, if you mix it with water at the nozzle, you get the best of both. At the scene of a forest fire, ashes are abundant. No need to transport anything miles away, or worry about freezing. I have used a coal stove, that has run away and overheated. There is nothing that can stop it. Water just turns to steam, and the effects are temporary. Ashes smother most fires
  8. Is there any way to run a cable that operates a governor? https://goo.gl/images/MpYMpR Why doesn't a shock absorber type work?I never knew they were called " dash pot "
  9. Thanks, will check into it
  10. Working on refining the linkage for a more useful motion. For a tractor, the shoes should have a linear motion for as much of the cycle as possible. After I get this optimized, I will attach legs, that alternately step forward.
  11. I don't know how to optimize this, but I have made a lot of progress

    Chimecycle motion analysis

  12. I am not a student, am not employed in this field of mechanical engineering. But I like to build machines in my spare time. I need cheap software that is relatively easy to learn. My computer can handle it, but I don't have time to learn Autodesk inventor, or others like that. I currently working on multi bar linkages for a skid walking machine. Have built them out of steel, but making changes is too difficult.
  13. On the subject of biomimicry, I haven't seen anyone try to replicate fish tails for marine propulsion. My idea was to use an array of fins, every other one moving in opposite sinusoidal motion. A cycle of compression, and suction. Since the fins would only move back and forth, seaweeds could not be wrapped around a propeller shaft. It would tolerate shallow water. The entire assembly could be actuated by a simple crankshaft with two cranks 180 degrees apart. I think the same principle would work for moving air, but I don't have time or money to build either
  14. Is it a problem if you had a flywheel, and or a governor that forced the input shafts to become constant speed?
  15. I agree, but I live in New York state, between Albany, and the Adirondack park. It is common to get 6 inches of snow, and sometimes 2 feet. I cannot even see where the road is when I am driving. How can a robotic car see the lines if they are covered?
