‘Build the wall’ with fiber optics

Posted by in categories: materials, transportation

A concrete or steel wall along the southern border of the U.S. is not impenetrable; daily news programs show how concrete walls are burrowed under or driven over with car carriers and hydraulic ramps, while steel walls are breached with grappling hooks and inexpensive metal saws. And while a fiber-optic fence is also vulnerable to a physical cut, it can be discretely buried or placed along existing infrastructure, and (unlike concrete or steel) can fundamentally detect the location of a cut with high accuracy so that border patrol agents can be dispatched to understand the breach and apprehend the humans (easily distinguished from animals) crossing over the fence.


Let’s put our money and photonics technology to more effective use.

Saint Jean Carbon is developing graphene gel salt water batteries

Posted by in category: materials

Saint Jean Carbon has announced that it is developing a new form of graphene battery technology and will start building the first prototype of its graphene gel salt water batteries. Batteries based on this technology should charge faster, run longer and theoretically may last indefinitely. The project’s long term goal is to have a series of three full production batteries ready for launch in spring 2020.

Saint Jean Carbon stated that salt water battery technology has been in research for about 5 years. Continued advancement slowed due to limited voltage capacity in comparison with Lithium batteries. Now with the use of graphene in a highly concentrated salt water gel, graphene can now be used without worrying about the graphene re-stacking, which would reduce the intercalation rate. Salt water batteries are much safer, won’t burn and have significantly less raw material cost.

The Company plans on building a “flex” production line that will allow a number of companies to share in the facility on a fee for use basis. The Company’s first production will concentrate on three specific battery types:

One in five Americans wants to live forever

Posted by in categories: life extension, materials

While it might not be quite as big a concern, the environmental impact of death care is also something Americans are paying attention to. Around four in ten (41%) Americans are somewhat or very concerned about the environmental impact of traditional burial methods.

On a similar note, 45% agreed with the statement, “People need to rethink the way we currently deal with ‘death care’ in regard to the environment.” And 11% said that they would like to have a green burial with shrouds and biodegradable material after they die.

Some of the possible environmental impacts of a traditional burial include embalming fluid leaking into the soil, large amounts of water being used for cemetery maintenance, and wood and metal caskets leaving behind toxic residue.

The World’s 10 Most Deadly Minerals

Posted by in category: materials

This stuff is “natural”…


Precious minerals make the modern world go ‘round—they’re used in everything from circuit boards to tableware. They’re also some of the most toxic materials known to science, and excavating them has proved so dangerous over the years, some have been phased out of industrial production altogether. Listed below are the 10 most deadly minerals on earth. These rocks do not need to be thrown to hurt you!!
