Nano filtering and pumping systems and methods of use thereof for nanoscale gaseous materials by utilizing materials having nanosized perforations through the materials. The perforations generally have an inner diameter similar to that of nanotubes, and in some embodiments, carbon nanotubes are disposed within the perforations. Such materials can partially organize molecules in random motion to move either some selectively or all of them, to create pressure differences and hence motive forces, or cause air flow into pressurized area. Because air is a cloud of particles separated by vacuum, the systems and method in air can be used to create motive force pushing any form of vehicle, lifting force for any form of air vehicle, air compression, power source for any form of machine, conveyor or generator, using the solar energy stored in the air in the form of heat, 24 hours a day, worldwide.

A cryogenic pump includes a drive assembly and a pressurization assembly operatively coupled to each other. The drive assembly includes a housing having sidewall and piston slidably disposed therein, the sidewall and a first surface of piston defining expansion chamber. A fuel supply valve is provided in fluid communication with supply of liquid cryogenic fuel and configured to selectively provide liquid cryogenic fuel into expansion chamber. A heating element extends at least partially into expansion chamber to heat and facilitate vaporization of liquid cryogenic fuel, thereby increasing pressure within expansion chamber and causing movement of piston in first direction. The pressurization assembly includes barrel defining bore and a plunger slidably disposed therein to define pressurization chamber for receiving liquid cryogenic fuel. The plunger is driven by the piston such that the movement of piston in first direction causes movement of plunger to pressurize cryogenic fuel within pressurization chamber.

According to an example, a microfluidic device may include a transport channel having an inlet and an outlet and a plurality of pump loops extending along the transport channel. Each of the plurality of pump loops may include a first branch, a second branch, and a connecting section connecting the first branch and the second branch. The first branch may include a first opening and the second branch may include a second opening, in which the first opening and the second opening are in direct fluid communication with the transport channel. The pump loops may also each include an actuator positioned in the first branch, in which the actuators in the pump loops are to be activated to induce a traveling wave that is to transport the fluid through the transport channel from the inlet to the outlet.

A network of microfluidic channels may include at least three loops interconnected at a junction. Each of the loops may include a fluid channel having a length extending from the junction to a second end; and a fluid actuator along the fluid channel and located at a first distance from junction along the length of the fluid channel and at a second distance less than the first distance from the second end. Activation of the fluid actuator of selected ones of the at least three loops may selectively produce net fluid flow in different directions about the loops. In one implementation, a fluid channel having a fluid actuator may have a bridging portion that extends over another fluid channel.
