  1. We would need more information... Stopping the flow after a certain volume of water is let out?
  2. This sort of design would yeild very high compression. You probably would not need a spark plug.
  3. You sir, have your strokes all messed up. A "stroke" refers to the travel of the piston. The four strokes are: 1. Intake -- The piston is travelling down, sucking in the air/fuel mixture through the open intake valve ports. 2. Compression -- The piston is travelling up, compressing the air/fuel mixture (Remember PV=nRT; it gets pretty hot). All valves are closed at this point. 3. Ignition -- The spark or glow plugs ignite the fuel forcing the piston down (this stroke is sometimes referred to as the power stroke). Valves are still closed 4. Exhaust -- The exhaust valve opens to let the exh
  4. I've been currently trying to design a hydrolic CVT that is simple enough for a bicycle. Shifting would be done by rotating a bidirectional valve to favor either a setup designed for torque or a setup designed for high rotational speed... I don't want to give out too much details, but just food for thought.
  5. I think NO.. And Yes... No if you're thinking about it as a fuel source, because its molecule is too stable already to easily find a pathway to a more stable combination. Yes if you think about it as a battery which contains hydrogen... If you were to fill a tank with water and KNO3 as an electrolyte (not sodium chloride because there is a risk of creating deadly chlorine gas) and apply electricity to perform electrolysis on the water. You are storing power from the electricity in the hydrogen. Thus you're using water and hydrogen as a battery. There is a net loss, so you will not get as m
  6. I still don't see why large scale VAWT's (Vertical Axis Wind Turbines) aren't around yet. They can use magnets as frictionless bearings, the generator and gearbox can be on the ground (or near the ground) and they never have to adjust for changes in wind direction.
  7. I'm still waiting to see (or possibly design myself) a biodiesel powerplant that feeds it's exhaust (CO2) into algae ponds or bioreactors and grows its entire fuel supply.
