When the noble transistor technology was developed, the computers and many other electronic devices became relatively smaller with time with the development of the interrated circuits that housed thousands of microtransistors. The number of transistors in ICs are incrasing exponentially with increase in scientific reasearch and inventin. Intel Atom founder, Gordon Moore predicted that the number of transistors in intergrated circuits will double every two years leading to development of smaller devices with more power. Such smaller devices are also speculated to use less power and become more efficient than their predecessors. It is like this prediction is coming to be very true like the dream of Martin Luther King. Currently engineers are spending sleepless night working and researching about this. At the moment, engineers have developed the world’s smallest steam engine that is “a few micrometers wide, or roughly the size of a water droplet in a fog. The devive is both confined and powered by a “trap” of laser light and it sputters abit. The fact that it works at all, however may push the boundary of what is possible in engineering microscopic machines” -WIRED.COM http://m.wired.com/wiredscience/2011/12/smallest-steam-microscopic-engine/. However this step posses quite some challenges as the size of such machines become less than 10, 000 times the size of the atom especially the Brownian Motion. The engineers are not in any way perturbed by these constraints but are determined to achieve more and more smaller and effective devices. What do you have to say about this?
