    "concept_summary": "Grebennikov reported that the chitinous exoskeletons of certain insects exhibit a 'cavity structural effect' that can compensate gravity in a localized zone, producing antigravitational forces and partial invisibility. Using bionic principles he built a platform that allegedly hovers and can travel at speeds up to 25 km/min.",
