I remember reading that of the $20 million cost of a launch only about $500,000 was due to fuel, so this is a complete game changer.
Right idea, but wrong numbers. A Falcon 9 launch, not including the cost of the payload itself, is nearly $60M, while the fuel for it is only a quarter million.
There is no adapter that will make a rotary phone work on a touch-tone-only phone network.
Oh, but there is!
Or you could skip DTMF all together and go straight to SIP.
And what's wrong with e-cigs? All the nicotine, none of the carcinogens.
I know I saw a headline just in the past week or two saying that wasn't the case.
What controls the band gap? Supplying energy to excite atoms and cause electrons to jump to the next shell, opening up holes that increases electrical conduction. What defines the amount of energy in an atom? Heat. What is the measurement for bulk heat density? Temperature. So, as temperature goes down, the heat content goes down, and energy state goes down. The semiconductor becomes an insulator. As temperature goes up, heat content goes up, energy state goes up, and you're now a conductor. Hence, semiconductors are fundamentally thermally controlled electric (thermoelectric) devices.
If your chip's temperature brings the energy level above its band gap, your semiconductor will simply not function, and this temperature is well below your semiconductors functional mechanical limits. If your chip's temperature means the energy level is well below the band gap, your semiconductor will need to run at a high core voltage and consume a large amount of power to bring the energy level (and temperature) of the gates up such that they will conduct and switch.
The problem is that transistors are thermoelectric devices. You switch them on and off by heating them up to change their conductivity. Silicon chips can withstand temperatures well beyond the point at which the plastic packages they are mounted to break down, but that temperature is also well beyond their switching point, making them useless as a computational device.
If you could produce a semiconductor that was useful at 3000F, then that would be its normal operating temperature, and you would need to feed it a high enough core voltage to allow it to heat itself up to that temperature to switch.
