Many combat androids are going to be heavier than a similarly sized human, but the point was that there weren't any really low-level summons to practice up on. That makes things a bit harder.
It also makes it harder that you'd have to somehow get your name on their summon scroll - or find and speak with their monarch, and convince that worthy to give you a new one. This makes things rather more difficult for both viruses and combt droids (or at least requires that the story be filled with rather more crack)
Mind you, I do recall a somewhat entertaining story about some guy (not Gai) who wound up with his name on the Succubus scroll. (Gai doesn't need it. He's got that tongue-pushup thing.)
Note that ninja are not burning chemical energy, or fusion power. They are burning life energy - essentially consuming little bits of their souls, which they then grow back. It's why chakra exhaustion is so lethal, and why the more powerful elder ninja always end up as such freaks. Now, it *would* be interesting to find out what the explosive yield is on a soul....
