Clean Drinking Water More Cheaply

Posted on by

More Cheaply? Doesn’t sound right. Anyway, This new technology relies on a 3D printing method to make membranes for reverse osmosis desalinization plants. As long as it doesn’t create another problem with the used membranes (unlikely) any help in lowering desalinization cost would be very helpful.
Experts develop 3D-printed device that could reshape our drinking water: ‘This … is what makes our technology special’

Ionic Thrusters

Posted on by

Back in 2002, our Physics teacher introduced me to a student who wanted to build an ionic thruster. I had never heard of one, but I was able to tell the young man where to obtain a high voltage power supply (and give him a long lecture about safety). A few days later he popped by to show me a device constructed of balsa wood, aluminum foil and stainless steel wire that would levitate (it was anchored by its power supply wires) when connected to about 15,000 volts. I was kind of blown away to say the least. That young man is an engineer now and ionic thrusters have continued to be developed by NASA. Here is a further demonstration…

Great series.

Silencing Science

Not that it was a surprise that Trump/Musk and their crew would do this, it just stinks.

National Cancer Institute Employees Can’t Publish Information on These Topics Without Special Approval

Jeeze. We have an unqualified celebrity, conspiracy theory lawyer running our public health system. Not a doctor or public health official, no qualifications whatsoever. Fantastic. Oh boy I’ll bet those right wingers who were worried about free speech will angry about this, right? Lol, nope. Their defense of free speech is highly specific.

UPDATE: – Even more stupidity…

Experts Warn of Public Health Risks as the Trump Administration Eliminates 2 Critical Food Safety Committees

and…

Trump considers easing safety screenings for chemicals

Assuming the United States still exists then, only three years, 10 months and 9 days more to go.

Thank Goodness Someone is Finally Testing Vaccines!

Now we will finally know if vaccines actually work!

Now That Trump Has Banished the Woke From Science, These Truth-Telling New Scientific Papers Reveal What COVID Vaccines Actually Do to Children

Oh, wait. They work. And they always worked? Gee. What a surprise. Maybe they’ll invent one for Measles.

By the way, Fun Fact: The first person to mandate inoculation was George Washington during the Revolutionary War. That woke S.O.B.

So it begins…

Trump administration’s abrupt cancellation of scientific meetings prompts confusion, concern

Do not forget that this man’s most fervent supporters are vehemently anti-science, and as a populist, he will give them what they want.

Oxygen from the Ocean

Posted on by

Okay, this could be a real game changer. People have been talking about mining manganese nodules (metal nodules made from a number of rare metals) from the bottom of the ocean floor since I was in elementary school. Just as the technology is being developed we discover this…

Oxygen discovery defies knowledge of the deep ocean

If this is true, mining these nodules could be another heavy straw on the camel’s back as far as the ocean is concerned. Our world ocean is already stressed to the breaking point.

New Material From NASA’s Glenn Center

This is awesome news. 3D printed metals have the capacity to change so much. Just another reason why NASA’s Glenn Research center is an awesome part of NE Ohio! Ignore the talking heads at the end. Why does every local news station think I want to listen to the anchor’s opinions on each story? Please just shut up and read the news.
