Your lifting-body with joined wings is nearly identical to Wenzel's design...

Are you still doing the manned glider stuff? I liked one design and wonder if it could be done for seated flight, like the one Julian Wolkovich designed...

I haven't done this yet so DYODD, but:
I imagine it's possible to get hydrogen for much cheaper than helium via electrolysis. Stainless steel tubing is probably the logical choice for electrodes.
What I plan on doing:
By sealing one end of the cathode with my lifting balloon and wrapping the outer diameter of the tube in an insulator like electrical tape: I think the balloon will fill with hydrogen.
I'm going to be proceeding with caution because the welding supply store employee I spoke to about buying a cylinder of hydrogen told me it was worse than acetylene. Nasty burns/death potential. The possibility of electrode arcing comes to mind for instance. When I do this, I'll be doing it outdoors in the middle of nowhere and I'll be using a piece of surgical tubing between the balloon and the electrode to try and isolate the balloon from the potential ignition source as much as possible.
I do not recommend anyone else try this as I have no qualifications to back the procedure I'll be using. This is as bubba as it gets.
