Wow, think of it, a 50 Watt supply. You could almost get that into your Pinto to haul around.....Seriously, 50 Watts needs to have a time factor to figure out your answer. If it was 50 Watt hours, then this would be a 50 amp hour battery, or about the size of your car battery, Q phone would last about 60-70 times as long as it does now. the desk top charger you have is not a 50 watt supply, but more like 700 milliwatt supply.
Batteries are rated in Amp - hours...how many Amps it can output for how many hours. The Q phone is somewhere around 900 milliAmp hours, or .9 Amps for one hour. but there are alot of conversions that take place between the battery and the power amplifier. The power amplifier may be at a higher voltage and you need some kind of power converter to get there, so this may have some loss in it which takes power. So perhaps a 200 mWatt transmitter would draw say .02 amps at 10 volts (watts = volts times amps), but if your power converter takes 10% loss to get from the 3.6 volts of Q phone to 10 volts, then you would take (using amps=power*loss/volts) (200mW*1.1)/3.6 volts=61 millamps, or 0.61 amps. So if these were the numbers, you phone would last about 1.3 hours. the Q is better than this but I just plugged in numbers to show how to figure it out simply. There is alot more than this which goes into the calculation and it takes a whole spreadsheet to do it right, but I hope you get the picture.
As for flamables in batteries, I guess it is ok for you sailing types, but us airplane types may get a bit of a hassle....80). Better yet to make a micromachine in which the active ingedient is water and you decopose Hydrogen and use that in a small micromachine turbine to generate electricity directly.
Can anyone tell me what frmT is in the Quote.com chart? Where did it come from? What market was open until 1.5 hours after the market was closed? |
