Egypt: population growth

Here's an interesting graph of Egyptian population growth. Up approx 400% since 1950. And up 21% since 2000. I wonder what GDP per capita looks like?

Update:
According to Wikipedia, inflation-adjusted GDP/capita increased about 3-fold from 1981 to 2006, even as the population increased approx 75% in that time period.

Update 2:
A Wolfram Alpha search on 'Egypt gdp per capita' gives the current figure and a time series graph. I expect it's not inflation adjusted. Anyone know how to get that from Wolfram?

Chevy Volt: 1000+ mpg?

From the dashboard of a Chevy Volt owner: 531 miles using 0.5 gallon (US) of petrol. Nice.

Wow. Over 1.5 billion hearbeats in my 50+ years on the planet...

Declining cost of battery storage

Green Car Congress cites a Deutsche Bank (DB) study predicting more efficient internal combustion engines (ICE) in the short term, with more electric vehicles (EVs) in the long term. DB is optimistic about the future of EVs, observing that laptop batteries (used to power Tesla's Roadster and maybe Audi's forthcoming eTron) have fallen in cost from $2,000 per kWh fifteen years ago to $250 per kWh today. That is equivalent to  a CAGR of -13.8% (see graph). If this trend continues, battery costs will be $57/kWh in 2020.

Note the standard laptop battery (cell) is known as an 18650 based on its dimensions: 18mm diameter x 65mm in length.

Food miles

Does local equal better? Not always...

• British tomato growers emit 2.4 metric tons of carbon dioxide for each ton of tomatoes grown compared to 0.6 tons of carbon dioxide for each ton of Spanish tomatoes
• cold storage of British apples produced more carbon dioxide than shipping New Zealand apples by sea to London. 
• U.K. dairy farmers use twice as much energy to produce a metric ton of milk solids than do New Zealand farmers. 
• Kenyan cut rose growers emit 6 metric tons of carbon dioxide per 12,000 roses compared to the 35 tons of carbon dioxide emitted by their Dutch competitors.

From:  The Food Miles Mistake

My view: a carbon tax or cap and trade would sort this out; the assumption that local is better is probably counter-productive.
