Could there be a future when planes don't slide off of snowy/icy runways? Could magnetic brakes in the runway slow the plane down while generating energy like a hybrid car? The technologies are all here, they just need applied to aviation.

Atmosphere: “Study on non-exhaust emissions in road dust,” Brake dust is radically different from tire wear. Greater penetration of EVs is changing urban air quality in a second beneficial way which has nothing to do with eliminating tailpipe emissions. “A new analysis in London, Milan, and Barcelona shows battery electric cars cut brake dust by about 83% thanks to regenerative braking.” However, the tradeoff is electric cars also tend to be heavier, so they can increase tiny particles from tire wear even as brake dust plummets. “Benedetto Giechaskiel, PhD, European Commission Joint Research Centre (JRCs ), has led peer-reviewed work into how pads, discs, filters, and regenerative braking shape these non-exhaust particles.” EV drivetrains convert velocity or kinetic energy largely back into battery charging, so the friction brakes work less, slashing the dust [as seen in the photo] that otherwise becomes airborne near crosswalks and bus stops. And brake dust tends to produce more airborne fine particles at the curb, which is what drivers, passenger, cyclists + pedestrians inhale. Notably, “only a small fraction of tire wear becomes airborne PM10, with one comprehensive review estimating about 1%.” And most tire fragments settle on roadsides, wash into drains or are cleaned up by street sweeping vehicles. “Particulate matter is not one thing but a mix of sizes and chemistries, and the smallest particles, PM2.5, are the fraction most closely tied to asthma attacks, heart strain, and early death.” Brake dust also carries metals like copper + iron, while tires shed rubbery microplastics + sulfur compounds.” While there is currently a tradeoff, the weight of batteries + motors is trending downwards, so this problem may disappear. Clearly, brake dust is dangerous + an 83% reduction is music to my ears. | 55 comments on LinkedIn
EVs will reduce dangerous PM2.5 air pollution in London, because regenerative braking cuts brake wear by 80% Another EV myth bites the dust #sorrynotsorry Chart source: https://lnkd.in/eyR-cyts More EV myths: https://lnkd.in/eAzyhgju | 16 comments on LinkedIn
There is something inordinately satisfying about reorganizing kinetic energy into electrochemical storage, instead of shedding it as heat.
Also the flip side of batteries adapted to high-rate charging is that regen is more efficient; hydraulic brakes kick in later. This car's battery (Bolt with "low" charge rate capacity) will sponge 80 kW or 107 HP.
And with EV batteries having amazingly low internal resistance, great round-trip efficiency. :-)

"In this video Justin does a deep dive explaining the most exciting innovation to ebike hub motors in decades. Freegen is a novel modification to motor design that allows geared hub motors to both freewheel with no drag AND ALSO do regenerative braking. There is no longer a trade-off of one or the other. And it does this without any of the extra complexity of a traditional controlled clutch.
This new idea from the Israeli company Chargebike not only solves that problem, it also provides an a proportional regen based on how hard the lever is squeezed AND it can maintain that braking force even when the batteries are fully charged, something not possible with traditional controls."
