Business Standard: “Nano-level 3D printing can have applications in medical science. A doctor can bioengineer a scaffolding to grow tissue cells for regenerating organs. These technological advances have a huge impact for sectors like biotechnology and material science. As companies look to create new materials that are versatile and ecofriendly, the printing will accelerate experiments to prototype cycle. Miniaturisation is another trend driving nano-level 3D printing. “The demand for smaller and more intricate components in electronics, medical devices, and other sectors drives the need for nanoscale 3D printing,” said a report by Persistence Market Research. “Nanoscale 3D printing, also known as additive nano manufacturing, is a revolutionary technology that allows the creation of three-dimensional objects with incredible precision at the nanoscale level. This groundbreaking technology has a wide range of applications across industries, including electronics, healthcare, aerospace, and materials science. The healthcare and electronics sectors are expected to be the largest and fastest-growing end-user markets for nanoscale 3D printing,” it said.”
Econlib: “The “information” you get by “asking people is often contradicted by the information you would get by observing what people actually choose – and as the old saw goes, actions speak louder than words. A deeper problem is that the information isn’t clearly available in pre-existing form even in our own heads, not even to ourselves. As James Buchanan put it in his book The Logical Foundations of Constitutional Liberty, “Individuals do not act so as to maximize utilities, described in independently-existing functions. They confront genuine choices, and the sequence of decisions taken may be conceptualized, ex post, (after the choices), in terms of ‘as if’ functions that are maximized. But those ‘as if’ functions are, themselves, generated in the choosing process, not separately from such process.” As a consequence, Buchanan goes on to explain, “The potential participants do not know until they enter the process what their own choices will be.””
WSJ: “Hundreds of companies have promised to produce large amounts of green hydrogen, but none have succeeded. Electric Hydrogen believes the secret to success is finding a better way to split a molecule. Investors believe it too. The company is the green hydrogen industry’s first unicorn…The molecule is water. Splitting it to create green hydrogen requires devices called electrolyzers. They are expensive and consume vast amounts of renewable electricity to make a small amount of hydrogen, making most projects uneconomical. Electric Hydrogen says its electrolyzer can produce much more hydrogen.”
NYTimes: “NASA is now plotting a return. This time around, the stay will be long-term. To make it happen, NASA is going to build houses on the moon — ones that can be used not just by astronauts but ordinary civilians as well. They believe that by 2040, Americans will have their first subdivision in space. Living on Mars isn’t far behind. Some in the scientific community say NASA’s timeline is overly ambitious, particularly before a proven success with a new lunar landing. But seven NASA scientists interviewed for this article all said that a 2040 goal for lunar structures is attainable if the agency can continue to hit their benchmarks. The U.S. space agency will blast a 3-D printer up to the moon and then build structures, layer by additive layer, out of a specialized lunar concrete created from the rock chips, mineral fragments and dust that sits on the top layer of the moon’s cratered surface and billows in poisonous clouds whenever disturbed — a moonshot of a plan made possible through new technology and partnerships with universities and private companies.”
