• A comment on Talk: Lee Cronin: Print your own medicine

  Feb 25 2013: Most of the replies for this talk are more interesting or more convincing than the actual talk itself and that is saying a lot already. One of the few talks that has annoyed me and I have watched them all. I agree with Donald Ripatti's reply and Rik Delaet's reply. This talk is almost at the level of "Branwdo is good for you because it has electrolytes" if not lower..

• A comment on Talk: Donald Sadoway: The missing link to renewable energy

  Apr 15 2012: I know since he is talking about solar or wind he doesn't mind the loss of energy heating the battery but a lot of the energy gets wasted as heat.
  Also according to statistics from the US Geological Survey (USGS), current global reserves of antimony will be depleted in 13 years (even though probably more minining sites will be found across the world, we are not talking about a resource that is going to stay cheap). Also the vast majority of antimony (90%) is mined in China. Also Antimony and many of its compounds are toxic, and the effects of antimony poisoning are similar to arsenic poisoning. I hate to see this stuff leaking all over the country side as the casing gets old, let alone the potential mess it is already causing in the manufacture of lead-acid batteries (were Sb is used).
  I really really do not want more Antimony in my water table.
  
  I wouldn't want one of these batteries in my home, they will all be potentially explosion/fire hazards, given the temperature they run, even if we put aside the possible toxicity issues.
  
  For these reasons I do NOT think this techonology will ever go beyond the pizza size and will stay in the specialized market realm.
  
  
  
  Anyway if I were a betting man, I bet on Hydrogen, it is simple, it is clean. It is after all the first element in the periodic table : ) -

  Having said that, loved the chat and I am all for more research in the liquid metal batteries.
  
  ps best comments are Matthew Slyman's Tal Gitelman and Donald Mitchell (as usual), cudos!

  A comment on Talk: Roger McNamee: Six ways to save the internet

  Nov 13 2011: I wonder when the growth of the invisible web (or deep web) is going to become an TED talk. The deep Web is several orders of magnitude larger (and growing) than the surface Web. He did indirectly mention it, when he says index searching is shrinking (what he didn't say is that it is shrinking far faster, to the point of become insignificant, than he mentioned since his graphs didn't include invisible web content, which by definition, is not indexed).

  Apr 2 2011: So many people thriving for excellence & collaborating for something productive and beautiful. I do not cry but this one time I cracked. I am so glad I am not the only one.

• A comment on Conversation: Artificial Intelligence will supersede Human intelligence

  Mar 30 2011: We will have artificial intelligence, and when we do there will be nothing "artificial" about i. How do I know? Reverse engineering. We will reserve engineer our own brains eventually, it is not a question of if, but when.
