PDAs, Cellphones, Wireless A major deal just went down in the United States, which seriously shakes up the mobile industry on the other side of the pond: AT&T has announced it plans to buy T-Mobile USA from Deutsche Telekom.

Well, the electric cars are interesting but we just do not have the ability to produce enough energy to run them, even with nuclear power. We can afford to run some of them for PR purpose but we just can't put an electric car in the hand of even half the people who need transportation.

As for heating, in my opinion, the solution is isolation and low heat.

So, what do you think about the idea of dropping individual cars, having people travel with bikes and public transportation instead when possible, but keeping them for...
-Heavy loads (postal services, delivery, buses, professionals like plumbers who need to carry heavy tools around as part of their job)
-Events where speed is a critical issues (medical emergencies noticeably)
-People who technically can't use bikes and public transportation for some valid medical reason

I can't imagine why we'd think we can't produce sufficient electricity to power cars - we produce enough petrol to spare, and that comes from a single freaking source that has been "about to be exhausted!!!" my entire life.

Electricity can be generated from darned near anything. Heck, Dean Kamen's team has invented a generator that can power an entire village just by sticking a pipe into a pool of raw sewage. It "pollutes" by producing 400 gallons of pure water a day as a by-product. (If you get a chance to hear him speak about it, or the "city of the future" they are building in Florida, don't miss it. The guy makes me proud to be an engineer.)

You're thinking about technology as the problem; technology is the solution. We're just using the wrong technology for the long term.

I'm all in favor of public transport and bicycles and such, but I think you underestimate for how many people that won't work well - particularly in a geographically diverse nation such as the USA.

Energy efficiency is also a great goal, but Garrett's Constant (9.7 mW/$) implies that wealth is directly proportional to our ability to generate energy. See http://ricegf.posterous.com/modeling-society-as-a-heat-engine for my thoughts on his work, including a link to his original paper.

The solution isn't to enforce less energy use on a rebellious people, but to make boundless energy use sustainable and the most attractive commercial option. You won't need laws - you won't be able to keep people away!
