Oh mann...hatte gestern nen SUPER ORGASMUS, als ich mich gefingert hab...bin so heftig gekommen ey, hab gesquirtet *spritz*
Aus den dortigen Comments:
John:
Assuming 100% efficiency: 2.5W = approx. 0.6 cal/sec = approx. 35 cal / minute. As a calorie raises 1g of water by 1grad, warming a 200ml mug of drink from, say 25 celcius to close to 90 (piping hot) would take 6 hours, unless my calculations are erroneous.
richie:
If the little snap pot being heated holds approximately 200cc (of water or similar), then to heat from say 20C to 60C, it would take 4 hours when absorbing 2.5W of energy. So, if you want a warm drink at lunchimes, start it off at breakfast and what the temperature rise by 10C every hour - oh yeh?
Mats:
It is not possible to make an usable USB-powered microwave oven. The usb port of a computer can only put out 2.5 watts. That means that what takes one minute to heat in an ordinary microwave would take about 5 hours in this one.

Really cute. I want one .......
*** but *** as an electronics engineer I am dubious of the claim that it can be powered from a laptop via its USB socket - And all because a USB port can only supply 0.5amps max, at 5volts max, so that's just 2.5watts of power, and something like this gadget would need considerably more.
I just do not believe its enough to kick start the magnetron (or similar) into generating the amount of microwave energy required to heat liquid matter of similar size to a small cup of coffee that normally needs a 800w microwave 2 minutes to boil....
But I'd love to be wrong on this.
