I'll put in a vote for: https://lcwo.net/ (Learn CW Online) If your goal is to be "conversational" in CW I suggest you crank up the character speed until you are not able to count individual dits/dahs an

I'd love to find a good number on the daily mileage of the median passenger car in the US. The average looks to be around 30-35mi/day but the median is probably a small fraction of that. Why would you want your battery pack to be

Where did you find those EU-27 numbers? I am seeing something around ~400B ton-km. > "Rail freight activity in Europe, measured in tonne-kilometers, grew from 339 Billion tonne-km in 2003 to 398Billion tonne-km in 2019" Page 14

Some light googling gives me 390B kilometer-tonnes[1] in Europe and 1.6T ton-miles[2] in the US for 2019. So that is 6x the freight movement. The US rail network also >2x longer than Europe[3] (360,000km vs 151,000km). [1] https:/&
