Vacuum Tube Technology Could Make Faster Circuits

Once it was invented in the late 1940s, the transistor began to replace the vacuum tube, and led to an amazing range of uses for solid-state devices and the variety of electronic gadgets we have today. Transistors offered savings in both size and energy. But one of the things that vacuum tubes provided was an obstacle free path for unhindered electron flow through the vacuum. "Electrons traveling inside a semiconductor device frequently experience collisions or scattering in the solid-state medium." The problem with vacuum tubes, besides their large size, is that they require high voltages to operate.

Not returning, but using aspects of them. [link] MT @BrandtCompanies Do you think we really will bring back the vacuum tube?
