    Hey David, so have you figured out by now that the electric car won’t shift well or brake normally without a clutch? What is the status of your electric car?


    • David says:

      There is no need for a clutch in an elecric car.  It shifts great, and breaks normally without a clutch.  You simply let up on the throttle, and you can shift.  And the clutch has nothing to do with breaking.  You do have to have your throttle set for a coast area if you use regenerative breaking (or a switch to turn it on or off).

        OK on the shifting, if you say so.

        About your home heating/water radiator set-up, have you entertained the idea of temporarily tapping into the system with a simple water hose outside? (to collect the solar heat collected in the waterhose during the hottest part of the day) You might even put a timer on the circulation within the waterhose during the time that is exposed to your best solar exposure. {my brother heats his swimming pool up by a few degrees, by simply circulating thru a water hose on the roof of the house, nearly free energy}

    Hey David, I’m curious if you are eliminating the flywheel,clutch, & pressure plate? And if so…why? I would think you need the clutch to -disengage the motor- for normal operations, like braking, changing gears, motor testing aside from the driveline, and the flywheel lends a great amount of inertia to the driveline to equalize sudden load/unloads. I just don’t see how you can expect to change gears without the clutch disengagement feature, please explain.

    Your adapter plate and splined adapter coupler, seem to be connecting direct drive, maybe I’m missing something.

      Yes, I am eliminating the flywheel,clutch, & pressure plate.  There is no need for all this with an electric motor since there is no compression cycles, or really any load when the power is removed from the motor.  To shift gears, simply let up on the throttle, and it will do the same thing as pressing a clutch on a regular ICE (Internal combustion Engine).  Also with an electric motor, I get an even torque all the way through the rpm range, because of this, many people actually run an electric vehicle with no transmission at all (just a gear reduction to simulate somethign simular to 3rd gear), or leave it in a set gear.  I would still like to have the option to change gears, so I left the transmission in place, besides I want to keep my 4wd functional.

      Thanks for your comments, and let me know if you have any further questions.

    For the chimne's, I used two 6" pipes with some dampers in it to force the flow to the outside of the pipe.  Once I am sure I am happy with my setup, I will update my website to show exactly how it is build.  I have changed a few things since I started testing it.

    Do you want the outside dimentions of the entire shed, or just the boiler?  The actual boiler is about 4'6" tall (including the 6" legs). and is about 3' long and 3'wide (I would have to measure for sure when I am home if you need the exact size.

    Man this thing is awasome! Had a couple of questions. What size pipe did you use for the chimney/exhaustm? Also was wondering what would be some rough outside dimensions of your boiler?
