The Future of Transit: The Solar-Powered Jetliner

skywhale1Solar-powered airplanes have already proven feasible, but only in the sense of single-seat, turboprop powered plane.s When it comes to a long-range, commercial jet aircraft, the field remains pretty sparse so far. But thanks to a Spanish designer, and some unconventional thinking, “whale planes” that are eco-friendly and combine the convenience of air travel with the luxury of a cruise ship might soon be a reality.

Oscar Viñals, from Barcelona, envisioned the “AWWA Sky Whale” concept plane as a mixture of today’s current designs and future concepts that don’t yet exist. The end result is like an Airbus A380, but with considerable expansion and designed to be powered by micro solar panels and four large hybrid electric engines that would rotate to ease takeoff and landing.

Despite the introduction of more fuel-efficient and less polluting turbofan and turboprop engines, the rapid growth of air travel in recent years has contributed to increasing CO2 emissions in the upper atmosphere.

In fact, in the European Union alone, greenhouse gas emissions from aviation increased by a total of 87% between 1990 and 2006. In 2005, global aviation contributed roughly 5% to the overall “radiative forcing” effect that our annual emissions of CO2 have on Global Warning, but the added effects of water vapor and the disruption to cirrus cloud formations also enhances this role to a varying degree.

skywhale4One of the reasons aviation’s role in Climate Change is overlooked is because the focus tends to be on urban infrastructure and automobiles, which account for the vast majority of carbon emissions. But given the current trend of increasing travel, international economic development, and growth in tourist industries, aviation is likely to get a bigger slice of that pie down the road and clearer methods need to be devised.

Hence the concept for the Sky Whale, which Viñals imagines would come with other futuristic components . These include a self-healing skin with adaptable opacity, active wings that change shape as needed, and ceramic and fiber composite materials. He even has a plan for the plane to break apart on an emergency landing, with the wings separating from the fuselage to limit damage to the passenger compartment.

skywhale3The three-story aircraft, which could accomodate 755 passengers, would have a wingspan and height greater than any of today’s biggest carriers – 88 meters in comparison to the 80 meters on an Airbus A380-900 – making it the largest commercial aircraft in existence. However, the combination of active wings (which would also reduce drag) and the hybrid-electric systems would render it the most fuel efficient.

Another thing that Viñals imagines would make it into the design is virtual reality windows – aka. display glass that allows people to go online, watch movies, and experience in-flight entertainment simply by looking outside. Can’t imagine why this would be necessary, as the range of personal devices people are likely to have by this time ought to be entertainment enough. And failing that, the view should be enough to inspire!

skywhale5Naturally, much of this technology – particularly the healing smartskin – is still many years away. But judging by the reaction to his designs, there is definitely some hunger for innovation in how we fly. Given the range of ideas for mass transit (like the Hyperloop, podcars, etc.) and personal transit (robot cars, robotaxis), it’s only a matter of time before the way we fly becomes smarter, sleeker, and cleaner.

  1. Well I give the Zeppelin Airship a change too…like the Aeroscraft ML866 funded by DARPA ok it was in 2007 or 2006 when I heard about it but hey what could be more funny that flying in a slow giant ballon XD
