A heat transfer tube includes a container, a cavity within the container, and a heat transfer medium located within the cavity. The heat transfer medium consists essentially of a solid-gas suspension of a gas and a substantially homogeneous nanoparticle powder located within the cavity. The cavity is in a partial vacuum state. The nanoparticle powder comprises Ca(OH), LiH, ZrH, or Mg(OH)in a solid state and is capable of substantially freely emitted and reabsorbing the gas as a function of temperature.

A high temperature solar power tower system includes a molten salt heat transfer medium, a high temperature solar receiver, and an energy conversion system. The molten salt heat transfer medium is capable of being heated to a temperature of at least approximately 1200 degrees Fahrenheit by the high temperature solar receiver. The energy conversion system uses the heated molten salt to generate power.

A solar-powered supercritical carbon dioxide turbine system includes a supercritical carbon dioxide turbine system and a solar heating system. The solar heating system has a molten salt heat transfer fluid for providing thermal energy to the supercritical carbon dioxide turbine system.

A dual neutron-gamma ray source comprises a compact neutron generator, a shield, a collimator, and an internal gamma target. The shield surrounds the compact neutron generator. The collimator traverses the shield from the compact neutron generator to a collimator port. The internal gamma target is positioned within the collimator to generate gamma rays from the neutrons.

Dual neutron-gamma ray source

A variable-ratio neutron-gamma ray source comprises a neutron generator, a shield, a collimator, and an external gamma target. The neutron generator generates neutrons and the shield reduces external radiation exposure. The collimator collimates the neutrons into a neutron beam that traverses the shield. The external gamma target generates a dual neutron-gamma ray beam from the neutron beam, wherein the dual neutron-gamma ray beam has a variable neutron-gamma ratio as a function of a thickness of the external gamma target.

Methods and apparatus are provided for a shield to protect a surface from the impact of hyper-velocity projectiles. The apparatus comprises a foam material that is configured to cover the surface to be protected and is attached directly to that surface. A coating material is typically disposed on the outer surface of the foam material and may penetrate the foam material to a predetermined depth. The foam material and the coating material are selected to form a composite having predetermined values of sonic velocity, toughness, and thermal conductivity. The composite of foam material and coating material can be significantly lighter in weight than a metal shield having equivalent protective characteristics.

A food-cooking vessel has a bottom plate and an upwardly extending continuous sidewall. A spigot assembly is secured to the sidewall above the bottom plate to allow draining of liquid from the vessel. A valve mounted in the spigot assembly regulates the flow of liquid from the vessel to an outlet spout. A filter is mounted in the spout to filter solid particles from the drained liquid. The spigot assembly has an attachment plate that is fixedly secured on the convex exterior surface of the sidewall surrounding a drain opening formed in the sidewall. A cylindrical attachment member is fixedly attached to the plate and extends through the plate into the drain opening without contacting the wall of the container, thereby avoiding the necessity of having the cylindrical member to conform to the convex wall of the vessel.
