Abstract: A method for producing a heat pipe includes the steps of providing a hollow body having a fluid filling end, covering the fluid filling end with an elastic sealing member, piercing the sealing member with a needle, extending the needle through the sealing member and into the hollow body, drawing out air from within the hollow body through the needle, and introducing a heat transfer fluid into the hollow body through the needle. The sealing member provides a passage for the needle when the sealing member is pierced, and contracts to seal the passage after the needle is removed from the sealing member.

The body is disposed in a receiving space confined by the inner surrounding wall.

Abstract: In a method and apparatus for generating kinetic energy, thermal energy is applied to a cylinder body of a first pneumatic cylinder to result in an expansion stroke of the first pneumatic cylinder and in rotation of a flywheel assembly that is coupled to the first pneumatic cylinder. A second pneumatic cylinder is coupled to the flywheel assembly such that the expansion stroke of the first pneumatic cylinder results in a compression stroke of the second pneumatic cylinder. The first and second pneumatic cylinders are fluidly intercommunicated when the first pneumatic cylinder reaches the end of the expansion stroke, thereby reducing the temperature of working gas in the first pneumatic cylinder and increasing the temperature of working gas in the second pneumatic cylinder to result in an expansion stroke of the second pneumatic cylinder, continued rotation of the flywheel assembly, and in a compression stroke of the first pneumatic cylinder.
