- 1964 Ken Balz Experimental Car - Ken built an electric-powered, radio-controlled model car which combined a Monogram 1:8 scale Big “T” plastic model car kit with an Orbit 4-channel radio transmitter and receiver. Two “Micro Mo” motors with 485-to-1 gear reduction were used, one for steering and one to power the car.

Cut-away view turbocharger (turbine section on the left, compressor section on the right) In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases.
Natural convection is a phenomenon where temperature variations in an environment generate fluid flow. Forced convection heaters utilize a device like a fan to generate air flow and spread heat at a faster rate. Sometimes called "fan heaters," these are often cheap but lack in efficiency and versatility. [2]
Aluminium alloy 2024 has a density of 2.78 g/cm 3 (0.1 lb/in 3), electrical conductivity of 30% IACS, Young's Modulus of 73 GPa (10.6 Msi) across all tempers, and begins to melt at 500 °C (932 °F).
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage.
In solid-state physics, the free electron model is a quantum mechanical model for the behaviour of charge carriers in a metallic solid. It was developed in 1927, [1] principally by Arnold Sommerfeld, who combined the classical Drude model with quantum mechanical Fermi–Dirac statistics and hence it is also known as the Drude–Sommerfeld model.
