So looking at the Fallout wiki gave me this idea. What would happen if the transistor. Was never invented? How might current 2013 OTL look like?

I highly doubt orbiting communications satellites would be economically viable if they had to be manned.

So, computers would consume more power, but would be roughly the same size and processor speed as OTL, and would not need cooling fans. Wireless phones would be larger and heavier, not because of the chip but because of the battery.
Satellites would have to be manned for tube replacement. Sorry, crewed arthur clarke had some stories set with such tech in the ?early 50s?If we assume computer technology continues to improve, and we find a way to make a better tube (micro-tubes?) I could see getting a computer down to a cubicle or two in size. Granted, the best computer in such a world would probably pale in comparison to some of our more advanced cell phones. Long lasting satellites would still be a problem as even a better vacuum tube would still have a shorter life than a transistor, and even if we could get a decade out of a tube by the year 2000, I doubt many private companies would be send satellites into orbit unless the passive reflectors are effective.

Vacuum microelectronics would last for several decades without tube replacement. And are more radiation resistant.
Solar thermal? Nah, plutonium RTGs.
And this is all besides the fact that this would be producing almost 110 kWt of waste heat (!) which would be quite difficult to dissipate effectively and would require 200 kg (!!) of Pu-238 per satellite. These alone would be major barriers to using RTGs.
And Pu-238 is in short supply.
