bchandark Yes something like that, but it is solid(NOT WALL), will hold elements away when it is powered(power system like with Liquid Crystal) and is lighter when powered to show that shield is working. If the shield is shutting down the shut down areas will "no-collide" with elements.
Hm, actually I think something like LED is not really present at all. Cloning photons and using an e-wall is not really the same as it is uncontrollable how many photons will be sent out on a short pulse. LED (and its couterpart the photo receptor) would really be a completely different element and would allow to take signals in all the electronic creations to a new level, especially with the new LCRY active optical switch element! We would probably have optical computers pretty soon
(I know, I suggested LED. But this is not to boost my ego, but from what I think would be much appriciated from what I read in this forum)
I suggest LCRY that changes colors depending on how many PSCN is charged to it or how frequent SPRK goes in. (useful for status lights) I also suggest an element that absorbs temperature to electricity. I also suggest a wall that absorbs particles then generates electricity. I also suggest a wall that changes the state that passes through it. (e.g. solids and liquids to gas) (useful for unclogging selective walls)
