I must not understand the definition of clog if our highways will be clogged with cars moving over 100mph. So the argument is the highways will be clogged because too many people use them but part of the reason they will use them is because they will be a faster, easier alternative to airplanes. Anyone else see a hole in that logic?

Actually, SQL Server does not provide a native JSON type which is one of the key benefits the author mentioned for PostgreSQL. However, there is a tool called JSON4SQL (http://www.json4sql.com) which is a port of the PostgreSQL JSONB type to SQLServer. That data type plus SQL Server is a pretty good alternative to PostgeSQL.

I definitely have noticed my Model S losing range at night but nothing like what is described in the article (which was written in March by the way). In fact, I went to France for 10 days in August and left it sitting at the airport while I was gone. If I had the type of loss described in the article, the battery would have been almost dead when I returned. Instead, I only lost 2-3 miles per night and had almost 200 miles of range left when I returned. I realize this wasn't cold weather, but it was only 10% of the loss described in the article.

Just curious where you got "Even if you doubled worldwide solar cell output every five years..." considering that PV production has gone up by a factor of about 7 in the past 5 years and is doubling every 2 years making it the world's fastest-growing energy source (according to The Earth Policy Institute). That is not even to mention that the pace is accelerating as a new wave of technologies comes to market (50% growth last year). At the current rate of growth, and using your numbers for production required, solar production would supply the equivalent of all of todays energy in less than 24 years. Not that I think that will happen since growth will curtail eventually, but your numbers based on a 5 year doubling are way off:

It is also worth pointing out that the earth receives enough energy from the sun in 40 minutes to match global energy consumption for all of 2006. So basically we would just need to capture 0.008% of the total energy available from solar radiation to provide enough energy for today's level of use. Given the advance of technology and the value of energy to mankind, I hardly think that sounds like a far fetched goal.
