Frontier Tech 1

I was wondering what sort of power rating one SEU translates into. How much electricity does it take to power a laser beam? I see that researchers managed to produce a laser beam that used 1 megajoule. It was in regards to researching nuclear fusion. What started me wondering was seeing how some of us allow players to modify an energy clip to be used to jury rig (another nautical term, btw) a powered door or some tech device or other. If a standard energy unit is one megajoule, how many times can you open and close a door with a full clip? If a megajoule is the approximate kinetic energy of a one-tonne vehicle moving at 160 km/h ( as per wikipedia) then can you use it power a hover bike to move it 20 meters down an alley? <br />I realise that the game creators don't compare to the scientific brain trust we have here, so it may be more trouble than it is worth to nail this down. But can anybody come up with a reasonable measure of energy to represent one SEU? And what are you thought of using energy clips as a jury rigged power supply?<br />
