I was reading the article with stunned disbelief at the BBC's lack of fundamental feasibility verification. And then I was unpleasantly surprised that I had to scroll down so far here on HN to see someone call out the bullshit. From the exaggerated numbers for aviation fuel cost to the ridiculously low cost of electricity all the quoted numbers are obvious lies. Not to mention that a back-of-the envelope calculation shows that the aircraft would never be able to take off due to the weight of batteries required for a 650 mile range. You would be absolutely right in staking your engineering reputation on calling bullshit and I would happily join you.
