Tesla was so swamped with complaints about driving ranges that it created a secret team to cancel owners' service appointments, source says
  • Yeah... EVs are totally built for stop-and-go traffic or city driving. For those uninitiated, everytime you slow down with a ICE car, all that kinetic energy is just being turned into heat on your break pads. Meanwhile for an EV car, that energy is then converted back into electricity to charge the battery - this is the same reason why Hybrids have so much better fuel economy. Adding to that, an ICE engine is only ~30% efficient in converting the energy in gasoline to energy for moving the car (the rest being turned into heat, vibrations, noise) whereas an EV is about ~70-80% efficient. You might not go as far while highway driving an EV, but it took a lot less chemical energy to take you there, meter for meter.

  • Taipei 101, Taipei, Taiwan
  • That's a very cool building!

    Maybe not so evil with its environmental outfitting.

    From Wikipedia:

    The elevators of Taipei 101 that transport passengers from the 5th to the 89th floor in 37 seconds (attaining 60.6 km/h (37.7 mph)) set speed records.[11] In 2011, Taipei 101 was awarded a Platinum certificate rating under the LEED certification system for energy efficiency and environmental design, becoming the tallest and largest green building in the world.[12][13] The structure regularly appears as an icon of Taipei in international media, and the Taipei 101 fireworks displays are a regular feature of New Year's Eve broadcasts and celebrations.
