Some of the appropriate technology is already out there, in construction nail guns. The Hitachi/Paslode guns use a battery to ignite the gas fuel charge, but most of the big manufacturers (Dewalt, Milwaukee, Ridgid, Ryobi, etc.) are selling cordless nailers in various configurations that actually work on bateries alone. They are heavy and expensive and slower than their pneumatic counterparts, but they work. That technology could be scaled to work in our guns at some point. But I still don't want or need one.
