The technique he used to create structural strength was talked about a great deal back when I was a young college student in the mid 1970s. I attended a presentation back then on its potential use to replace conventional building materials for home construction. Geodesic domes were all the rage back then as well. Then they had the inflatable buildings, the new bicycle design where you lie down on your back, and attaching springs to your legs to augment running (curved metal ... not like Wiley Coyote automobile springs on the bottom of your boots -- but the first experiments were with Pogo sticks). For years now, companies have mixed chewed up cardboard with other recyclable materials and mashed it all together into a strong, light-weight biodegradable material. It works better overall than the technique used by the bicycle hobbyist.
Correlation does not prove causality!
