Hey all, I've seen the listing from various people about a "quiet spark gap" and i've thought of a design. now if i'm not mistaken, sound waves travel using Airwaves. Now what would happen if i were to stick a sparkgap in a Vaccum environment? wouldn't there be no noise since it can't travel? the only concern w/ this design is if the sparks would still occur. As we all know, fire needs air to ignite, but do sparks need air to jump? thanks alan
