Jaunting belts - The TP were unable to jaunt long distances without special belts which they wore at all times. These allowed them to jaunt across the world or into space. Otherwise their jaunting powers only worked for very short distances.
Stun guns - The TP were unable to deliberately kill and could not use serious violence. This could cause difficult situations when they encountered hostile people or aliens. The solution to this was stun guns that would knock out their enemy or enemies for a few minutes. When fired, the stun gun would make a small hissing noise and cause a burst of light.
AE Suits - AE means 'Adaptable to any Environment'. These were suits that covered the entire body and were complete with a helmet. In these, the Tomorrow People could breath oxygen, stay warm in a cold environment and stay cool in a hot environment. The suits could also change appearance, so as to avoid attention. Like a Babelfish, they could also translate alien languages.
