• this cant be real?
  
  USB = MAX 5W
  
  thats 5 J / second
  
  thats only 300 Joules per minute
  
  it takes 4200 Joules to raise 1kg of water 1 Degree C
  
  assuming that small looking pot is 200g, and its mainly water, then it would take:
  
  2.8 MINUTES to raise the temperature of those beans by 1 degree C
  
  to get it from room temp (20) to a hottemperature (say 70C) would take 2 hours and 20 minutes?!?!
  
  and that's assuming that the pot doesnt loose any heat -and it would probably be loosing heat faster than than this would be putting it in Posted by Chris, UK
• I'd imagine that it could run off of a couple of mobile phone batteries for a short 1 or 2 minute burst, and recharge from USB. Also it may not need to get as hot as you suggest, as reheating to about 50 degress might be acceptable for a coffee or a pot of beans.
  
  You could do the maths better than me, is this feasable? Posted by Bryan, UK
