 A concrete structure using air for buoyancy became Innis’ PSP (pneumatic stabilized platform) patent.The PSP technology Innis invented uses air movement to reduce wave loads and distribute them through the platform, a platform that could be used to house offshore airports, oil and gas production facilities, floating islands, military bases, and additional real estate for coastal cities.The technology enables the platform to extract energy from ocean waves to create electricity and is less costly than most currently used large open ocean platforms.
