Abstract: A pumpless solar energy-based air heater includes a body housing a chamber surrounded by a heat conducting medium; an intake pipe to draw cool air into the chamber; and one or more exit pipes to push warm air out from the chamber, the one or more exit pipes having one or more structures within the interior of the one or more exit pipes to create a low friction factor for the air flowing upwards in the exit pipe while creating a high friction factor for the air attempting to move downward, thereby ensuring air flow in an upward direction; a pressure difference is created between an entry point of the intake pipe and an end point of the one or more exit pipes, thereby eliminating the need for a pump or a fan.

Abstract: A system and method comprising the steps of: depositing a first electrode metal on an insulating substrate or layer; creating a trench component, in which said trench component comprises a section of said first electrode metal or both first electrode metal and insulating substrate or layer with a depth based on at least one of, a molecular device element, a trenched bottom electrode, and a liftoff molecular device (TBELMD) to be produced; insulating said first electrode metal from a predetermined material deposited in said trench component; and depositing a second electrode metal on said predetermined material deposited in said trench component.
