Venus is made of the same stuff of Earth, almost twins - except for water. Venus is bone-dry and hot enough to melt lead at 836 degrees F (447 degrees C), and has a thick atmosphere but no water vapor is there. Earth harbors an enormous volume of water, even if its interior is possibly hotter than Venus. Venus is closer to the sun, and probably had as much water as earth at one time but heated up early-on to this temperature and then poof - the water disappeared, billions of years ago.
Why should you care how hot it is there or why Venus has no water? Hmmm... well the reason that I found these seemingly unconnected factoids interesting, was in surfing the internet - in pursuit of 15 THz and LENR. 15 THz could be one key to LENR. If you don't believe me look up the papers by Hagelstein, Cravens and Letts. What !?! you ask. Where is the connection? Well, it seems that 15 THz is 20 micron wavelength. A photon of 20 microns has a mass energy of .062 eV. .062 eV is equivalent to 447 C (836 F and 720 K). Curiously this is the exact temperature of Venus. If you want to experience what 15 Terahertz looks like, hurry out with a telescope and find Venus in the night sky. It is in the far infrared and would glow even without reflected sunlight. And 15 THz is a water resonant frequency ... but catch-22 Venus has no water. Is there a connection in all of this, or is it coincidence ? Not sure ... just doing a little googling and angling, so to speak - throwing out provocative associations like bait. :-) Hoping to haul in a big one someday...
