Halleluiah, a resurrection to end all technology resurrections, the rebirth of the Polaroid film pack! This Zink printer, “inkless”, as they claim, uses the Polaroid “inkless” film pack technology to make high resolution pictures.
For you youngsters, Polaroid instant pictures were almost as ubiquitous as “Brownie” cameras during my adolescence and young adulthood. I think that […]
It seems that everyone is looking for ways of scavenging power from, well anywhere. This physics professor challenged his doctoral student to improve the design of a thermoacoustic engine driven by waste heat to make sound energy. This, in turn, vibrates piezoelectric devices to generate electricity.
There are sources of waste heat everywhere, and for the […]
This article points to the possibility of using heat to make a thermal logic gate, which could be a great way to make a new type of computer that is powered by a heat source. At first pass, it didn’t really strike me as that significant. After all, just because you can build a logic […]
This snippet of an article published in the Applied Physics Letters may be the harbinger of something of huge importance. While graphene is a sheet of nanoparticles, and therefore not immediately relevant, the area of work (specifically in the thermoelectric arena) is one of great impact. If you think about all of the available direct […]
Ever since the term “Hydrogen economy” crept into our vocabulary, the counter argument has been storage: How do you store this energy source in a way that makes engineering and economical sense?
First, we wanted to compress it into super cold – 253C liquid H2 tanks. This provides the fastest access to […]
