Comment carbon footprint? (Score 5, Informative) 189

Single bitcoin transaction ~741kwh wasted energy. Which is equal to 5000 km on Tesla3. I wonder how many transactions did they make to collect these 1.5B. I bet they didn't do it in single take. Buying Tesla car with bitcoin transaction may make the deal less environmentally friendly than buying ICE car with bank transfer or credit card.

Comment Re:pilots should fly, not debug software systems a (Score 1) 257

With two underwing engines, reducing thrust introduces some additional dive moment. They were low and already diving. Reducing thrust may not look like a good idea in this circumstances. Roller-coaster might be difficult to apply too when you are low and already going down. This is crazy that you cannot trim passenger airplane manually in its normal flight envelop.

You totally forget about 5000m altitude. I would rather live in place with -53C in Alberta with normal atmospheric pressure than anywhere higher than 4km. Human beings have serious issues with adapting to such altitudes. http://en.wikipedia.org/wiki/Altitude_sickness http://en.wikipedia.org/wiki/Chronic_mountain_sickness http://en.wikipedia.org/wiki/Hypoxemia In addition to that you also have much higher frostbites risk even from not-so-low temperatures.

here are more photos/videos of the plant before and after the accident - http://forums.drom.ru/hakasiya/t1151240353.html There is also a lengthy discussion of accident on the local forum (many plant workers participate and deliver "first hand" news there) - http://forums.drom.ru/hakasiya/t1151239745-p104.html Transformers look ok, there were no smoke nor traces of fire damage. Hydraulic surge in generator #2 looks like most likely reason of the accident (the reasons of surge are not that clear still though, people talk about destruction of turbine or generator failure).
