Consider getting on to an airplane with nuclear-powered engines.
Consider the consequences if an atomic airplane crashes.
The Boeing Company last week received approval from the U.S. Patent and Trademark Office for an airplane engine that combines the use of lasers and nuclear power.
â€œBoeingâ€™s newly-patented engine provides thrust in a very different and rather novel manner,â€ heralded Business Insider.Â
Itâ€™s a leap into mad scienceâ€”and backwards to a 1950s notion of nuclear-powered aircraft.
The patent approval to Americaâ€™s biggest airplane manufacturer comes as solar power and green fuels are being shown to be feasible energy sources for flightâ€”as they are for uses on earth.
Last week an airplane using only solar power, Solar Impulse 2, landed in Hawaii after flying across the Pacific. Itâ€™s to go on flying around the world. Also last week, in an expansion of the use of biofuels for aviation, United Airlines announced the start of flights between Los Angeles and San Francisco of jets using fuel derived from farm waste. United further said it will invest $30 million in one of the major producers of jet bio-fuels, Fulcrum BioEnergy.
The Boeing scheme would have lasers in an airplane engine bombard deuterium or tritium causing a nuclear explosion with its force providing thrust.
Business Insider features a video on its website page with its article on the Boeing patent that features Deepak Gupta, founder of PatentYogi, a YouTube channel. Gupta declares: â€œThis is another cool invention from Boeing. Boeing has patented nuclear power aircrafts. The engines of these aircrafts include a unique propulsion system.â€
As Gupta explains the process:
â€œA stream of pellets containing nuclear material such as deuterium or tritium is fed into a hot-spot within a thruster of the aircraft. Then multiple high powered laser beams are all focused onto the hot spot. The pellet is instantly vaporized and the high temperature causes a nuclear fusion reaction. In effect, it causes a tiny nuclear explosion that scatters atoms and high energy neutrons in all directions. This flow of material is concentrated to exit out of the thruster thus propelling the aircraft forward with great force.â€
â€œAnd this is where Boeing has done something extremely clever,â€ Gupta continues. â€œThe inner walls of the thruster are coated withâ€¦Uranium-238 that undergoes a nuclear fission reaction upon being struck by high energy neutrons. This releases enormous energy in the form of heat. A coolant is circulated along the inner walls to pick up this heat and power a turbine which in turn generates huge amounts of electric power. And guess what this electric power is used for? To power the same lasers that created the electric power.â€
â€œSoon,â€ says Gupta, â€œtiny nuclear bombs exploding inside a plane may be business as usual.â€ He adds: â€œI would love to use these non-polluting aircraft.â€
Is the Boeing scheme really the basis for non-polluting aircraft?
No way, says Jim Riccio, nuclear analyst for Greenpeace. â€œSince the supposed â€˜Nuclear Renaissanceâ€™ [the effort to build more nuclear power plants] is dead in the west, there are some who are stretching to find applications for nuclear powerâ€”and this is a very long stretch.â€
â€œImagine getting into an airplane that has minor nuclear explosions for propulsion,â€ said Riccio. And â€œwhat about the implications of such an aircraft going down? We just saw an F-16 come down over South Carolina, its jet engine landing in someoneâ€™s backyard.â€
â€œMeanwhile, we have breakthroughs in solar energyâ€”to the extent of that solar plane showing solarâ€™s potential,â€ said Riccio. â€œSolar energy is being used to accomplish things that nuclear couldnâ€™t, as we watch solar costs plummet and nuclear go through the roof. The future is solar, not nuclear, despite Boeingâ€™s attempt.â€
Garry Morgan, long experienced in radiation issues including as a nuclear, biological and chemical warfare specialist in the U.S. Army, notes that â€œthis is not the first time atomic engines for aircraft have been tried.â€
In the 1950s the U.S. military developed nuclear-powered aircraft but ran into the huge problem of requiring â€œheavy shieldingâ€ to protect pilots and crew from radioactivity, noted Morgan. He is now director of community radiation and health monitoring for the Bellafonte Efficiency & Sustainability Teamâ€”Mothers Against Tennessee River Radiation, initiatives of the Blue Ridge Environmental Defense League.
In the militaryâ€™s Nuclear Energy for Propulsion of Aircraft project of the 50s, ground tests were conducted of atomic airplane engines. A B-36 bomber was renamed an NB-36â€”NB for Nuclear Bomberâ€”and made numerous test flights with an onboard reactor operating although not used to power engines.
Regarding the Boeing scheme, the result of the Uranium-238 being struck by neutrons would be [that some of it is] transformed into Plutonium-239, said Morgan. Plutonium has long been described as the most toxic radioactive substance, and Plutonium-239 has a half-life of 24,100 years; thus once created it remains radioactive for 240,000 years.
â€œI donâ€™t understand how they are going to overcome the emissions problems and how the shielding issue would be handled,â€ said Morgan.
As to a crash of an airplane with atomic engines, â€œIt would be a real mess. Youâ€™d have lethal material spread all over the place.â€
The patent lists Boeing, based in Chicago, as â€œapplicantâ€ and the â€œinventorsâ€ of the proposed engine as: Frank O. Chandler, director of Advanced Vehicle Subsystems and Technologies at Boeingâ€™s The Phantom Works; Boeing engineer James S. Herzberg; and Robert J. Budica, who has been Boeingâ€™s director of strategic technologies.
â€œAs of now,â€ says Business Insider, â€the engine lives only in patent documents. The technology is so-out-there that itâ€™s unclear if anyone will ever use it.â€
In a 1960 book, Nuclear Flight: The United States Air Force Program for Atomic Jets, Missiles, and Rockets, edited by Air Force Lieutenant Colonel Kenneth F. Glantz, then Air Force Deputy Chief of Staff for Development, Lt. General Roscoe C. Wilson spoke of nuclear bombers with â€œunlimited rangeâ€ being on â€œmissions of several days duration.â€
Nukespeak: the Selling of Nuclear Technology in the USÂ by Stephen Hilgartner, Richard C. Bell and Rory Oâ€™Connor, published in 1983, with a new e-book edition in 2011, relates:
â€œAtomic-powered airplanes would make long-distance bombing easier, since the planes were expected to be able to circle the globe without refueling.â€ As late as 1959, it notes, the Joint Chiefs of Staff were assuring Congress of the military potential of nuclear-powered aircraft and urging that they be built. But nixing the program in 1961â€”after more than $1 billion in 1950s dollars had been spentâ€”was then Secretary of Defense Robert McNamara who told Congress that an atomic airplane would â€œexpel some fraction of radioactive fission products into the atmosphere, creating an important public relations problem if not an actual physical hazard.â€Î¦
