O transístor é uma das mais profundas inovações em toda a existência
da humanidade. Descoberto em 1947, este evoluiu como poucas outras
coisas na historia; actualmente conseguimos colocar biliões de
transístores em processadores complicados em áreas menores que a da
unha do dedo mindinho. Após décadas de inovação, contudo, o
transístores estagnaram. As velocidades de relógio não progrediram
muito desde 2005 e o processo de fabrico de 20nm deverá ser mais
oneroso que o anterior de 28nm, algo inédito. Agora, investigadores
da NASA acreditam que poderão ter descoberto uma forma de evoluir os
transístores novamente ... usando tecnologia dos primeiros tempos da
computação: As válvulas termiónicas.<br>

innovations in all of human existence. First discovered in 1947,
it has scaled like no advance in human history; we can pack
billions of transistors into complicated processors smaller than
your thumbnail. After decades of innovation, however, the
transistor has faltered. Clock speeds stalled in 2005 and the 20nm
process node is set to be more expensive than the 28nm node was
for the first time ever. Now, researchers at NASA believe they may
have discovered a way to kickstart transistors again — by <a
