We need an alternative that people will us...Henry,<br /><br />We need an alternative that people will use.<br /><br />Bikes are one of those things that people will use -- if they have no other choice. There are obviously enthusiasts, etc. but most of the people riding bikes in the suburbs are doing it for leisure and not to get from A to B for a purpose. They will ride home and get in their cars for that.<br /><br />Fact is, if people are going to use their cars some of the time then we need roads.<br /><br />People are probably choosing electric bikes in China for economic and practical reasons -- bikes are cheaper and congestion is bad. Many people don't feel those constraints in North America (an increasing number do, but we're not near a tipping point), so what do we do? Force people to use bikes? They can use bikes already if they want -- the roads are there.<br /><br />As a mostly-pedestrian, sometimes bike rider, and occasional car user, I find cars incredibly wasteful and sometimes aggravating, but I am just one person, we live in a democracy, and most people don't agree with me.<br /><br />Shifting over to your vision requires a serious reorganization of life. It can be done over time, but in the short term we need something to bridge the gap, though I don't think it will necessarily be the electric car. Improvements to the conventional car or hybrid-like technology seem most likely to me.mattbghttps://www.blogger.com/profile/00531548248683577666noreply@blogger.comtag:blogger.com,1999:blog-8861605.post-10021818666278211782011-01-07T21:34:22.264-05:002011-01-07T21:34:22.264-05:00@Mattbg

The only way to keep roads viable is to have as many people as possible paying for their maintenance, and roads are essential to the economy.mattbghttps://www.blogger.com/profile/00531548248683577666noreply@blogger.comtag:blogger.com,1999:blog-8861605.post-40838000167034489252011-01-03T15:49:29.733-05:002011-01-03T15:49:29.733-05:00Not electric cars.

Well, they've been around since the Almighty used to run around in diapers and their basic problem remains unchanged: energy density of batteries. At least of the affordable kind. <br /><br />However, some fellows do come up with some interesting ideas from time to time and might even help us to figure out how to deal with the mess we're in:<br /><br />http://www.energybulletin.net/stories/2010-10-27/book-excerpt-american-citizen%E2%80%99s-guide-oil-free-economy-chapter-1-electrified-and-<br /><br />Nice article, Kurt.José A. de Souza Jr.http://jos_desouza@yahoo.comnoreply@blogger.comtag:blogger.com,1999:blog-8861605.post-2605943760387662052011-01-03T02:21:44.677-05:002011-01-03T02:21:44.677-05:00Another issue is the 50% to 60$ loss of energy wit...Another issue is the 50% to 60$ loss of energy with each conversion of its form; from coal to electricity, from electricity to chemical energy in the battery, from chemical energy to electricity, and from electricity to mechanical energy in turning the wheels. In addition, there is loss in transmission over electrical power lines.<br /><br />One will need three or four times as much energy at the source as is present in gasoline or diesel fuel.Robin Dattahttps://www.blogger.com/profile/15358491380192365005noreply@blogger.com
