3D-Organ-Printing

Here’s an article I found about a very interesting and almost futuristic use for “3D-printing”. The term “3D-printing” actually refers to additive manufacturing technologies, which means that an object is created by adding up different layers of a certain material. A common method uses an inject printing system with a special powder as a material to produce the consecutive layers of the object. In reference to kotoku’s post on the discussion board about the “skin-gun” I will post the following article from Quirks & Quarks (click on link below.) The stem cells of the specific organ are directly taken from the person, who’s supposed to receive the organ, are then multiplied and used as material for the 3D-printing process. It will still take time until the method is developed far enough for clinical use, but it would open vast opportunities.

Interesting fact: They printed a miniature-2-chamber-heart and 46 hours later it actually starts beating (see audio-file on the website below.)

Nanoholdings – Clean energy for the future based on Nanotechnology

Some time ago I found this presentation from Justin Hall-Tipping, CEO of “Nanoholdings LLC” about new developments of how to use Nanotechnologies: Justin Hall-Tipping: Freeing energy from the grid.

One of the company’s fascinating new technologies is a form of transparent carbon composed of carbon nano-tubes. These nano-tubes conduct electricity far better than copper. Combined with a polymer a small, brief voltage can change the carbon from being transparent to being shaded in different colors. This could regulate the permeability of light through windows.

Another innovative development of the Nanoholdings LCC is “NIRVision”, a way to build night-vision devices without the use of complex electronics as in conventional night-vision devices, by creating a flexible film that could be integrated into standard glasses or even windshields of cars. The film consists of a photo-detector layer that converts infra-red light into electrons which then stimulate an optical layer, like a thin flexible display. The overall thickness of the film will be less than 1/2000th of a millimeter!

Combining these two technologies would create a foil that can change state from being transparent to being shaded while also being able to generate electricity from infra-red light 24 hours a day and according to Nanoholdings LCC be the foundation for future self-sufficient energy generation in homes.
