I am sure we could make a lot more money getting the jump on the market for all-electric car ring tones than all our quantum physic gibberish will get us.
These could range from the blast of a Ferrari V-12, to historic roar of a Spitfire Merlin engine (it produced about 1200 hp and had 8 inch straight pipes), to a growl in a very famine voice that must meant something.
We an also throw in a external stick-on cup holder and a program that answers back to toll both thank yous.
