  1. Re:How is this different? on New 3D Printing Process Claimed To Be 25X Faster Than Current Technology · · Score: 3, Interesting

    Specifically, how is this different from other projector based stereolithography printers such as the muve3d DLP (http://www.muve3d.net/press/)?

    You are right. I was unaware that projection with polymers were already a known method. We searched for 3D printers that do a complete layer at once some time ago when we developed our process and found none. We just began testing LCD panels and UV backlight. It is a sinle layer at a time, UV polymer isn't actually the fastest method I have discovered. It is possible to do it with much greater precision and higher speed using different methods. I put up a video a month ago about this (LCD) technique on my web site moteyways.com. I don't think this is very innovative and 41M$ is hardly staggering, but surprising for something with so little innovation. Structure is the least useful printable thing. We are working on printing a new type of CPU and the technology will be documented on the site. It is all to be open hardware. I think that a printer that can print circuits is the application that makes 3D printing a useful thing instead of a play-doh factory or glue gun. I realize it can be a tool for lost wax to metal, but many other tools are better suited to manufacturing structural items. I saw a piezoelectric lathe designed in Japan that can cut almost any material in a 5 axis system with astounding precision. Piezo systems can operate at Angstrom scale ( with huge forces ) and I can attest to that as it is the same method I use in my atomic force scope.

    So the sewer bots will be powered by urine and manufacture explosives from the nitrates and will be equipped with sensors to smell each other. So the robot overlords will be under?

  7. Re:photoelectric effect on New Technology For Converting a Metal To a Semiconductor With a Laser · · Score: 4, Interesting

    We've known about this since the turn of the last century. It's the photoelectric effect. Every material has a wavelength where if it is struck by a charged particle at or above that, it will absorb it and then emit an electron. This isn't news.

    What's news is that we've now reached a sufficient level of understanding regarding the engineering of electro-optical systems that we are starting to build devices where the primary logic is based on optics, not electronics. This is an advancement of technology, not of understanding.

    I am a bit confused by what you said. An incident photon at wavelength (Lamda) or smaller will eject an electron ( photo electric) and thermal excitation of a material like the cathode of a tube will also eject electrons. I am not getting where the charged particle comes in. From TFA:

    In other situations, light can modify a material’s behavior — but only when it’s absorbed, transferring its energy to the material. In this experiment, Gedik says, the light’s energy is below the absorption threshold. This is exciting, he says, because it opens up the possibility of switching a material’s behavior back and forth without inducing other effects, such as heating — which would happen if the light were absorbed.

    What they are talking about is changing the bandgap with the incident angle of polarized infrared laser light.

    I'm not surprised ('social networks' in general make you the product, linkedin has always been a touch sleazy, especially for an ostensibly 'professional' site that could theoretically be making its money on the semi up-and-up by offering useful recruiting services);

    Linkedin has many dubious methods that aren't visible to a typical person. I know some of the methods they employ to extend their grasp. The problem is that there is no way to explain this to people without a CS degree. It just irritates the victim to be a tool so they ignore it.
    To go from ironic to sardonic as well as a self deprecating , we are providing social comments on a site owned by a company that handles employment (DICE). So it is posters on a 'social network' that complain of the use of themselves as product on a 'social network'.
    But, that aside, I agree that this is right out of the ball park for sleaze and greed.

  10. Super caps are neat for their application but suggesting they are useful for this is a stretch. It seems from RTFA that they think 5 Wh/Kg is comparable to 128 Wh/Kg for Li-ion . Also the incorporation into silicon presents serious issues that never get resolved in less than 10 years. No sane company is going to incorporate this in a line of CPUs and then find out that after a year they like to release their energy in one single burst. I suggest we test them in 747s first to make sure they are safe and do not pose any risk to my CPU.

Sometimes this happens when contractors are asked to create a system and then get paid. If they don't get paid, they leave the back door.

The issue seems to be -who- gains from what is laying around in the open or what can be inferred. The present model seems to revolve about connecting products to sales and taking a cut. That does not seem to be a sustainable gain. It requires that the consumer be actively involved in the process and people can simply stop using the internet without dying.

    The biggest advantage that could be achieved in 3D printing is the self replicating printer. That would seem to be the best focus for a first design.
    There are many ways to achieve that goal and I have tested several methods that can be integrated in a single device. The challenges include working directly to metals, printed electronics, precision and speed. These are all attainable goals and it seems that the hype goes more to what can be done to monetize and control the industry of 3D printers.
    There is no doubt that other things can be done when the proper framework is created. It seems that the technology is at that threshold similar to the first integrated circuits on a chip and a complete microprocessor. The real progress comes when the device can successfully duplicate itself. It would be the Cambrian explosion of the personal industrial revolution.
    It presents many new problems for society as a whole because it short circuits the consumer pathway from manufacturing to sale. The actual cost of products drops radically when you cut out several layers of middle men. There is no doubt that it will eventually happen. There is also no doubt that the existing economic and political structure will vehemently oppose such a process.

A combination of technologies using 3D printing, integrated circuits, and techniques developed by studying the homeobox genes (HOX) has a more realistic chance of producing results.

Nature has designed a composite structure and parts can't be added or subtracted to enhance memory or IO without changing its balance. It functions as a whole like the universe that it models. The universe functions on factorial infinities and even the best brain will only cut a small slice of those infinities.

All of these advances can be positive and what worries me is the fact that the original motives define the direction of application. What seems to be the motive is to extend a dominant biological position into a dominant mechanical position. In other words they want to create a mechanical system that rules the biological as an extension of their own biology. They are confused and they wish to extend that confusion to gigantic proportion.
