    This month marks the 40th anniversary of humankind's first steps on the moon. Auspiciously timed is Craig Nelson's new book, Rocket Men--one of the most detailed accounts of the period leading up to the first manned moon mission. Here, we have ten little-known Apollo 11 facts unearthed by Nelson during his research.

    To joker5delta, He3 will only be useful after we have a workable Fusion Reactor! That's like drilling for oil in the early 1800's, they knew where the oil was but we didn't need it in large enough quantities to go after it.

  • Honda FCX Clarity

    Highways filled with hydrogen cars are still decades away, but that doesn’t diminish the achievement of rolling the first fuel-cell car off a mass-production line. To open up interior space, Honda developed its own fuel cell, a 100-kilowatt stack that packs substantially more energy into a 65 percent smaller space than other designs and squeezes neatly into the tunnel between the front seats.

    billdale has made good points for EV's. HOWEVER- He miss read this article. The current FCX has a 280 mile range, equivalent to my gasoline powered Honda CRV. So the argument of more frequent fuel stops is erroneous. Also the FCX does not use Liquefied Hydrogen, it uses Compressed Hydrogen! So his argument about "Hydrogen requires a combination of thousands of pounds of pressure at hundreds of degrees below zero" is also incorrect. The benefit of a hydrogen fuel-cell EV over a battery EV is weight. 100kW of batteries weighs more than the combined weight of the fuel-cell and hydrogen tank. Also refilling the hydrogen tank will be much faster than recharging a 100kW battery pack. I look forward to when I can produce hydrogen from my roof-top PV array and refuel my car with water. I believe that both battery and fuel-cell vehicles will share the road. Much like today with gasoline and diesel vehicles both being popular. The right technology for the it's proper use.
