Comment Questionable assumptions made in this study (Score 5, Informative) 432

This study made many questionable assumptions like the life span of the battery (only 150.000 km, but Tesla has actually warranty up to 192.000 km), they used for their assumptions always worst case scenario for electric cars and best case scenario for diesel cars. Also they compared apple with oranges, compared a Tesla 3 (351 hp) with Mercedes 220d (only 194 hp). It was already highly criticized in the German media. See for example Der Spiegel about this study (in German): https://www.spiegel.de/auto/ak...

Comment Summary is also wrong (Score 2, Insightful) 644

Germany receives a bit more sunlight than Alaska, since slate.com was comparing apples and oranges.

Here is a really good explanation of US vs German solar energy:

"Germany’s annual exposure to the sun is actually not too different from the US east of the Mississippi, except for the Southern sunbelt from Texas to Florida, which does get more sun."

Comment Re:Backing up the entire OS (Score 2, Interesting) 520

All newer IBM Thinkpads use a hidden area on the HD to store the OS and all IBM software and drivers for recovery. If you want Recovery CD's, you have to create it yourself (takes 4 hours). If you call IBM support to ask for Recovery CD's, you need a good explanation like "SUSE Linux deleted the hidden Area".
