Things I learned this week 29 Apr 2012

• Philips introduced a 10 watt LED bulb to replace a 60 watt incandescent bulb. It'll last 30,000 hours - which is 20 years when used four hours a day. It should yield energy savings of $165 over its lifetime.
• Walmart has more employees than the population of Houston and is the largest priate employer in the US and Mexico.
• Billionaire entrepreneurs are now looking to mine asteroids for valuable minerals.
• The new plastic $20 bill could be out by the end of 2012.
• New Zealand thinks it can curb teen smoking by increasing packs of cigarettes to $100 by 2020.
• One World Trade Center will probably pass the height of the Empire State Building next week.
• If you bothered to read every privacy policy you encounter on a daily basis, it would take you 250 hours per year, or about 30 work days.
• Mayors from Vancouver, Burnaby, North Vancouver City, Vernon, Armstrong, Enderby, Lake Country and Metchosin call on the BC government to regulate and tax marijuana as part of a strategy to end gang violence and make communities safer.
• Vatican ATMs offered Latin as a language choice.
