With a new kind of nanoscale printer that works at record speed and detail, it is now possible to print an invisible ‘cloak’ to cover items. Military and magician customers alike take note, then. The printer, developed by CUHK engineer Prof. Chen Shih-chi , creates a metamaterial surface that can manipulate light, rejecting it if desired.
This operation can be performed without huge, high-throughput machinery. This means that it can be carried out at hundreds or even thousands of sites at nearly zero waste. Thus, one can imagine a future where every household can have a 3D printer for use

Placed side by side on the bending beam, the two MFC slices are available on the market and cost $700 each. ‘In mass production, the cost can be lowered,’ Professor Liao said. At a normal walking speed of 4 km per hour, the MFC human knee energy harvester generates 1.6 milliwatts of power, i.e., 1.6 millijoules per second.

For centuries, humankind was too busy struggling to put food on the table to worry about whether they had an exciting and life-enhancing career. But today, material abundance and technology advances have freed our hands and minds to expect much more ...
Is it normal or is it extraordinary for a 38-year-old to own two companies and one restaurant in a single building at Science Park? Are we treated to some Silicon Valley success story? These were our thoughts when we entered Sengital, Mr. Alan Lam's technology company. Pale yellow partitions defined the workstations of some lanky men in their 20s each glued to at least two computers on their ...
