--- Quote from: IanMacdonald on January 18, 2018, 03:30:33 pm ----Is it any wonder there is such a commuter problem? If the government wanted to solve this, they would: * Make it easier, not harder, for people to move to where there is work. * Discourage the building of 'dormitory towns' far away from any work or amenities. * Stop charging city residents a fortune to park outside their house in daytime. * Encourage remote working. * Make it more expensive for firms to service huge areas from one central depot. --- End quote --- You can't use cars to solve the commuting "problem" as they don't scale with dense cities, America tried a car centric approach and to fit in all the required car parking spaces they could never achieve densities to support mass transit and locked those cities out of getting any larger. https://www.theguardian.com/cities/2016/sep/27/cities-eliminating-car-parks-parking https://www.shoupdogg.com/wp-content/uploads/sites/10/2015/08/Putting-a-Cap-on-Parking-Requirements.pdf Mass transit (public and/or private variety) is the way to build shorter commute times and increasing the cost of car ownership is exactly they way to reduce congestion and commute times. If you can rent land for a fraction of the price to park your car on, can I get the same price and park a caravan on it then rent out the residence for profit? There are better uses for land and the free market can balance that well so if you want to park at your house you are free to purchase the land required and have the parking space for whatever purpose you desire. |

This is really good.. A "Must" read! In Car Nation part one: Cause by Nick Sousanis http://www.thedetroiter.com/jan05/carnation1.html In Car Nation part two: Effect http://www.thedetroiter.com/jan05/carnation2.html Except the problem is, the car was built for a certain time, which is drawing to an end. People in the future are not going to have the incomes or the need for private automobiles, because many wont have jobs as they did in the past. Others will work over the Internet, often for employers hundreds or even thousands of miles away. Also, some areas may become too dry or too hot or too polluted to support human habitation. Will people move back into the cities? |

LEDs are specified that way but most failures are complete and have nothing to do with that. Regulators confused operating life with reliability when they did the calculations for total cost of ownership. |

An LED's lifetime is specified as the time until it's light output it drops below XX% of its initial output. Whether that's due to gradual depreciation or fatal failure should not matter. I.e. in a test batch of LEDs, every reliability fault will also drag down the average operating lifetime. Edit: Typo |

So far Philips CFL lamps have worked well for me so I bought a whole bunch of LED lamps from Philips. edit: typo |
