An electronic vaporizer is provided. The electronic vaporizer includes a cartridge that facilitates provision of a vaporized solution to an individual. The cartridge includes a housing that includes an interior, wherein the housing is one of a polymer housing or a ceramic housing. The cartridge also includes a heating element located in the interior of the housing, wherein the heating element is configured to vaporize a solution for oral provision to the individual. The vaporizer may also include a power harvesting device operative to acquire energy from the environment for use with powering the heating element.

An agricultural fogging machine having or operatively connected to a supply of a liquid chemical, having a transfer pump which transfers the liquid chemical through a flexible conduit and, by receiving a control signal from a control board, controls the flow of the liquid chemical through the conduit, and having a heater housing which controls the temperature of the liquid chemical received from the transfer pump. The control board is electrically connected to the transfer pump and the heater housing so as to transmit the control signal thereto, and a relay is electrically connected to the control board and changes an output signal according to a current transferred to an electromagnet installed therein. The heater housing has a heat exchanger operatively configured to control the temperature of the liquid chemical exiting the fogging machine through a spray tube, and the control board generates control signals by receiving Wi-Fi signals.
