Built by Bonk Business Inc. in 1948, the Gnagg Booster is still found in many of the more esoteric laboratories around the world. It looks somewhat like a generator from the forties, with a green safety cover, lots of connectors for various peripherals (today the connector standards have changed, so it is hard to find suitable plugs) and on one end a conical shaft covered with a safety mesh. It runs on three small wheels, making it easy to move despite its heaviness.
It is a general waveconverter, able to transform energy at one frequency to another over a very wide range (8 Hz - 10^50 Hz, according to the manual). For example, it can boost sound into light, turn radio waves into electricity or downgrade gamma rays into gravity waves. One version, the "Freakwave Transmuter", is able to transform mental energies into useful power or vice versa.
[ This device can convert any force to any other force, as long as it can be connected to it. A Matter 3/Forces 4 effect makes it able to withstand even extreme loads without breaking. With the Freakwave Transmuter unit, it can also convert mental processes into energy and vice versa.]
