In central China’s Wuhan, the EagleDrive Flying Car debuted—China’s first full-ducted eVTOL (electric vertical take-off and landing) object.
🛸 8 rotors hidden inside the frame
🔇 Safer + quieter for urban skies
🤖 Goal: driverless airborne taxi in 5 years
High end composite flywheel rotors can achieve nearly a kWh/kg of rotational storage when magnetically levitated in a vacuum chamber. Consider mounting a flywheel in the middle of a wheel, such that magnetically decelerating the flywheel accelerates the wheel. Even if the flywheel was only 1% of the system mass, that is 0.01 kWh/kg, enough energy to accelerate the entire system to 600 mph.
Lots of practical system engineering challenges, and drag would consume more energy, but It would be amusing to outrun a top fuel dragster with a wind up toy.
⚠️ LO ÚLTIMO: Se ha descubierto que el YouTuber estadounidense Nicholas Light instó a sus decenas de miles de seguidores a calificar masivamente con 1/10 los episodios recientes de la tercera temporada de “One Punch Man” en la plataforma IMDb.
⚡️Este llamado al review-bombing (boicot de reseñas) explicaría en parte por qué el anime ha roto récords de baja puntuación recientemente. Aunque la producción ha tenido críticas legítimas, esta campaña organizada distorsiona la recepción real de la obra.
