By the way, there is NOTHING wrong with a crude prototype device. See the first transistor:

We don't need practical devices at this stage. We need working devices that can be tested. No one should care whether a device is practical or not. If we can persuade the public this is real, billions of dollars will be spent converting today's crude prototypes into practical devices. - Jed
