At its core, it is a digital stamp and an app. If you want to send a parcel, you’d simply stamp it with a device that uses a laser to etch it with your name and a unique identifying pattern. After that, the USPS would pick up your package; from there, the app would prompt you to provide the name of the person you’re trying to reach.
The problem is, will such a fine print even survive a journey?, how far can you send it before all the handling and sorting will make the mark unreadable to the sorting machines in the delivery office, or even worse maybe they will mark it as a fraudulent stamp(as someone has to pay for the shipping in some way) and they will "throw" it away" Link to Original Source
Kkloe (2751395) writes "US researchers have achieved a world first in an ambitious experiment that aims to recreate the conditions at the heart of the sun and pave the way for nuclear fusion reactors.
The scientists generated more energy from fusion reactions than they put into the nuclear fuel, in a small but crucial step along the road to harnessing fusion power. The ultimate goal – to produce more energy than the whole experiment consumes – remains a long way off, but the feat has nonetheless raised hopes that after decades of setbacks, firm progress is finally being made.
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to photons (energy). Fusion is the process that powers active or "main sequence" stars. -Wiki
Kkloe (2751395) writes "MIT professor Daniel Nocera claims to have created an artificial leaf, made from stable and inexpensive materials, which mimics nature's photosynthesis process.
The device is an advanced solar cell, no bigger than a typical playing card, which is left floating in a pool of water. Then, much like a natural leaf, it uses sunlight to split the water into its two core components, oxygen and hydrogen, which are stored in a fuel cell to be used when producing electricity."
