I'm also interested in this, perhaps using an aluminized mylar balloon or a large wire mesh with a Van der Graaf Generator and/or electron gun to maintain the charge. There's been a fair amount of research on electrohydrodynamic (EHD) vehicles (lifters), but I haven't seen any experiments using a large charged surface area to create an effect like buoyancy. http://jnaudin.free.fr/lifters/main.htm http://jnaudin.free.fr/lifters/main.htm
