Aviation world going greener

A hydrogen-powered car may be years if not decades away from reality due to infrastructure issues, but a hydrogen-powered plane? Already here. Boeing recently gave a hydrogen-powered plane its maiden flight, but cautioned the technology was just suitable for small private planes.

Meanwhile, in Paris, Orly Airport is tapping into geothermal energy for green terminals.

And, not just the terminals itself. A Hilton Hotel and two airport-based business districts will also be hooked into the system, which could provide one-third the area’s power.
