    Motor/Generator Unit

    This unit can be used for variety of purposes to illustrate energy transfers: it can be used to lift mass or stretch bungee cord, and to generate an electrical current when the mass falls again or the bungee cord is released. It can also be turned by hand to generate current. The motor/generator (6-9 V) is mounted on robust metal base, and the gearing of the unit and the sizes of the pulleys have been chosen to enable variety of qualitative and quantitative experiments to be undertaken.

    Energy Transfer Unit

    Developed for the Science Enhancement Programme (SEP) this single unit demonstrates range of different energy transfers; for example, how energy is transferred electrically from hand-turned dynamo to motor. The unit is accompanied by booklet that discusses some of the key teaching and learning issues that surround the energy concept, and provides series of activities that illustrate how the unit can be used to develop simple and coherent ways of talking about energy.

    Stirling Engine, Low Temperature

    An affordable Stirling engine which works at very low temperature differences. A cup of warm water (must be at least 60 °C) can make the motor run, which means that water heated by sunlight can become hot enough to drive this motor. Like other Stirling engines, this type works by converting temperature differences into mechanical energy as warm air expands and cold air contracts. This is utilized in closed system where the same air is pumped back and forth between cold and hot engine part. Illustrates perfectly how Stirling engines operate and can be used with many different heat sources. Weight: 330 g. Dimensions (H x W x D): 144 x 90 x 90 mm.

    Hero's Engine

    A functional glass model of the earliest form of steam turbine. Comprising borosilicate glass bulb 70 mm diameter, with side arms bent at right angles and formed into jets at their tips. The bulb is carried upon a metal stand which leaves it free to rotate about its horizontal axis. With 25-30 mL of water put into the bulb and boiled, the increased pressure ejects steam, which causes rapid rotation as per Newton's third law. Supplied complete on stand but without burner.

    Rijke Tube (Singing Pipe)

    The 'Singing Pipe' apparatus is a simple, effective and entertaining way to demonstrate energy conversion from heat (thermal energy) to sound energy. Quick and easy to set up and use, this demonstration rarely fails to impress. The apparatus consists of a 450 x 28 mm copper tube which has a metal gauze fitted inside, at pinch point part way up from the base. The tube should be supported by a retort clamp towards the top, away from the heat, and blue Bunsen burner flame directed into the base and onto the gauze for few seconds only. Shortly after removing the flame, the tube emits loud 'foghorn' sound as air is drawn up the tube by heat rising from the hot gauze. If the tube becomes too hot it will stop emitting sound, in which case it should be allowed to cool before trying again.

    Hyman Fire Piston

    This apparatus vividly demonstrates the rise in temperature that occurs when a fixed mass of air in a transparent cylinder is compressed by a hand operated piston. A piece of tinder, which is provided, ignites in the transparent cylinder: much as a diesel engine obtains ignition. The cylinder and piston can also be used to demonstrate the effect of decompression, being the immediate lowering of temperature and the consequent condensation of water vapour inside the cylinder the cloud formed can easily be seen. Cylinder Dimensions: (L) 198.00 mm (OD) 15.00 mm (ID) 9.00 mm
