  • Mar 20 2013: Elon is wrong about three things, at least, in his talk:
    1) fossil fuels. Though we could run out, we can make as much of it as we want through bio-fuels.
    2) Vertical takeoff and landing ... especially a rocket is asking for trouble. a much more viable plan is that of: Skylon by Reaction Engines LTD out of the UK. It is a far superior option to the reusable space craft design and implementation.
    3) 1300watts/square meter is the maximum you could achieve with solar at 100% efficient. we are currently at about 22% on commercial technology. You do the math, we do not have enough surface area available to provide our global power needs with solar. Keep in mind that the average location gets less than 12hours of sun a day.

      Mar 22 2013: Let us now actually DO the math on your statment no.3)
      1300w x o,22 = 286w/m²
      The worlds energy consumption is around 16 TW or 16x10^12 w
      16x10^12 w devided by 286w should give me the aria needed to cover the whole worlds energy needs, corect?
      so lets see, 55 944 055 944 m² lets see that would be about 5 594 km²
      the worlds land aria is 510.1 million km² or 5,1×10^14 m²

      please check if you find errors in my math that make your statment valid again, if not
      may i sugesst that in the future, you do the math before using it to try to prove a point.
