Technology..... using it to save or waste

Technology is a double edge sword. As new technology makes it possible to create innovations like cost effective solar panels to support and sustain us, we get closer using technology for achieving a more renewable and sustainable planet. Unfortunately, for every step forward, it is human nature to stray.

Russia recently tested a vacuum bomb ..... from this article it says that this new and bigger bomb is made possible via nanotechnology.

The bomb is smaller than the MOAB, employing nanotechnology to double the heat from a blast, according to the Russian military officer.

I have always though of advances and applications in nanotech as positive advancements form mankind (e.g. nanofilters for water filtration to remove the need for chemical treatment, reduce petroleum usage, etc) ..... I guess this adds a new twist to it
