Given the current laws of physics, flying cars are essentially helicopters, with all the attendant noise and risk of falling out of the sky.<p>Until the laws of physics change, it's likely we won't have flying cars. I give the odds of that change 10% in the next 20 years.<p>I'm watching the fringes closely, but nothing has shown real evidence yet. I'm hoping Barry-1 can <i>push itself into a higher orbit without propellant</i>... but that remains to be seen. You too can follow along, watching this page[1,1a], specifically columns 53–63 of line 2 of the Two Line Element set, the <i>mean motion</i>, which is orbits per day.... if that goes down, that is a higher orbit... it's been slowly increasing so far, as drag causes it to get into lower (and faster) orbits.<p>The first elements based on observation had it at 15.15327300, as of Nov 22 (5 days later) it's at 15.15439447. They hope to boost it's orbit by 100 Kilometers, which should take it below 15 orbits/day.<p>If it works, that means Mike McCulloch's Quantized Inertia is likely right, and we get to get out of this star system. Along the way, you get flying cars, and I get a personal megawatt.<p>[1] <a href="https://db.satnogs.org/satellite/QDDY-8878-5291-1819-3935#data" rel="nofollow noreferrer">https://db.satnogs.org/satellite/QDDY-8878-5291-1819-3935#da...</a><p>[1a] <a href="https://web.archive.org/web/20231125162752/https://db.satnogs.org/satellite/QDDY-8878-5291-1819-3935#data" rel="nofollow noreferrer">https://web.archive.org/web/20231125162752/https://db.satnog...</a>
