Heat Pipes – Part II Operating principles: capillary pumping pressure
In a previous article we introduced and described, from a general point of view, the Heat Pipes. Now, we want to present some general aspects concerning on the operating principles of these devices.
Heat Pipes – Part I: from aerospace to air conditioning applications
The heat pipe is a device of very high thermal conductance. Let’s find out the story and characteristicst behind this particular type of heat exchanger
AI and manipulation: how far can it go?
Does AI manipulate the users who interact with it? Are these new technologies really capable of influencing the choices and decisions of human beings? What can we expect from the future development of ever more complex systems and how will they interact with man?
Computers of the future: evolution or elimination?
The evolution computers have undergone since the sixties has been mind-blowing. They have transformed from huge machines that occupied entire rooms, to miniaturised, portable devices with an infinitely superior calculation capacity.
Smartphones and innovation: is the market really saturated?
It would seem that over the last two years the smartphone market has reached a point of absolute saturation, with a remarkable decline in sales. How did we get to this point? Can we expect a future upturn, or is the current decline irreversible?
