The Transparent Car

https://youtu.be/_-FgxTxBtU0 An ebike is the most efficient among personal vehicles but if local food eaten, the mileage can be 1,300 mpg, more efficient than a train. Velomobiles are even more efficient than bicycles. Fully powering them will make them even more efficient. A human power will consume more energy than electric motors.

To match the more sporty Velomobile, the frontal area need to be 0.4 SQ. m. The dimensions need to be smaller than 1/2. The width is 0.7m, with wheel well width of only 0.1m. This allows 0.5 m space for feet and rear cargo. Its frontal area of 0.395 is comparable to the more sporty Velomobile at a price for cargo space. Wheel base 1.4 m, length 2.25 m. Because the Transparent Velomobile is transparent, we can lower it's height but it's length has to be smaller than 2.25 m, in order to maintain its side view shape compared the other Transparent Car classes, which may result in a different coefficient of drag. For the most efficient, it's height can be reduced to 0.4 m, it's width, 0.5 m. The 1/2 Transparent SUV need to be 0.85 m, 0.15 m wheel well. Wheelbase 1.4 m. A more practical version uses 0.6 x 0.5 - (0.2x0.1)= 0.28 sq. m.

The fastest charging of LiIon battery is achieved by Xiaomi Redmi Note 12 Explorer at 200 W for a 5AH battery while still within the acceptable rate of degradation of battery. At 5V supply voltage, the charging current should be 40 A making the charging at 8 C. The following article discusses fast charging rate of only 4 C using only air cooling. Xiaomi has shown that with proper cooling, we can charge a car to as fast as 8 C which means 1/8 hour, which is less than 8 minutes. Xiaomi phone can be charged to 100 % in 9 minutes. If you charge a 10 kWh battery at 8 C, the charging current should be 80 kW. 20 kWh, 160 kW. 40 kWh, 320 kW. 320  https://www.nature.com/articles/s41586-022-05281-0 Article Published:  12 October 2022 Fast charging of energy-dense lithium-ion batteries Chao-Yang Wang ,  Teng Liu ,  … Brian D.
