Things I learned lately 8 October

• 325,000 buildings / houses in Canada are at risk of flooding from heavy rainfall and another 625,000 are at risk from flooding due to rivers breaching their banks. Worse, their owners probably don't know that their properties are at risk of flooding.
• At CodeCon, Elon Musk, the founder and CEO of Tesla, admitted that the current electrical grid isn't robust enough to handle the electrification of the entire vehicle fleet. He said that this is why he is trying to create more home based power generation via solar installations on all roofs.
• In Iceland, teen numbers for alcohol use dropped from 48% to 5%, and tobacco use from 23% to 3%. They did it through advertising bans, organizations to help kids solve their psychological problems, and most importantly, gave them access to free master classes on dance, music, art and sports as a means of stimulating the same brain biochemical processes that relieve stress as alcohol and nicotine.
• It would be rather pointless to build a pipeline to ship oil sands crude and bitumen to the east for refining because all eastern Canada refineries are built to process light and medium crude.
• When Persian oil was exploited by UK company BP, Persians (Iranians) didn't like that in 1951, they were only getting 17% of oil profits. So their democratically elected Prime Minister Mohammed Mosaddeq vowed to nationalize BP's interest. In 1953 the UK and US engineered a coup and effectively placed the Shah in charge, who towed the line.
• Harrison Ford was frozen in The Empire Strikes Back because, unlike Carrie Fisher and Mark Hamill, Ford had only signed on for two films. After the success of Raiders of the Lost Ark, Lucas didn't think Ford would return for the 3rd Star Wars film, but left him frozen just in case.
• Ben and Jerry's has a physical graveyard that they retire old ice cream flavours to, and you can actually go visit it.
• Cigarette filters were designed with color-changing chemicals to give the illusion that they filter out toxins. In reality, the filters have little to no health benefits.
