Things I learned lately 15 October

• Americans are finally learning something that the Germans have known for a couple of decades now. You can grow many types of crops under and in between rows of solar panels.
  
  
  
• The London Eye was meant to be a temporary attraction when it was introduced in 2000. Not one to let the observation wheel competition go unanswered, Dubai now has one, the 'Eye in Dubai', that is almost double the size of the London Eye, at 250 metres tall.
• The Tesla model 3 now outsells the Mercedes C Class, BMW 3 series, Audi A4 and Q5.
• Germany's Sonos Motors is building an electric city car covered in solar panels that can add up to 245km of range per week just from the sun.
• The undeniable fact about the oil industry since 2005 is that it has never seen such extreme price volatility. What we can extrapolate from that fact is that it would be foolish to base an economy on this price.
• Shell has admitted that its oil production peaked in 2019.
• Calgary's ring road, once complete in 2024, will be 101 kilometres long.
• Greater Tokyo's rail system (which includes its two subway systems) moves 40 million people. Every day.
