New glass could cut carbon footprint by nearly half and is 10x more damage resistant

Posted by in categories: energy, sustainability

Worldwide, glass manufacturing produces at least 86 million tons of carbon dioxide every year. A new type of glass promises to cut this carbon footprint in half. The invention, called LionGlass and engineered by researchers at Penn State, requires significantly less energy to produce and is much more damage resistant than standard soda lime silicate glass. The research team recently filed a patent application as a first step toward bringing the product to market.

“Our goal is to make glass manufacturing sustainable for the long term,” said John Mauro, Dorothy Pate Enright Professor of Materials Science and Engineering at Penn State and lead researcher on the project. “LionGlass eliminates the use of carbon-containing batch materials and significantly lowers the melting temperature of glass.”

Soda lime silicate glass, the common glass used in everyday items from windows to glass tableware, is made by melting three primary materials: quartz sand, soda ash and limestone. Soda ash is and limestone is calcium carbonate, both of which release carbon dioxide (CO2), a heat-trapping greenhouse gas, as they are melted.

Zaporizhzhia Nuclear Plant a Clear Present Danger

Posted by in categories: energy, health

See my explanation of the spent fuel rods and why if something is not done to get water to the spent fuel rod pools at the Zaporizhzhia Nuclear Plant there will be a catastrophic radiation release that may trigger WWIII. See why Russia and Ukraine are each saying the other is going to blow up the cooling pools and the plant. See what that means for you. Take your preps seriously!

Magical Material That Blocks Microwaves and Infrared Heat Also Shifts from Transparent to Translucent

Posted by in categories: energy, materials

A seemingly magical material can block microwaves, infrared (IR) heat, and light and then magically shift to a transparent state that also allows IR and microwaves to pass through simply by being stretched or contracted.

Inspired by the properties of squid skin, which can shift from translucent to opaque due to the presence of iridocytes and chromatophores, the new material could help create stealth materials, safeguard electronic devices, dramatically improve energy efficiency in commercial buildings, and even protect against microwave weapons.

No One Has Accomplished All of These Feats in One Material .

This Plasma Engine Could Get Humans to Mars on 100 Million Times Less Fuel

Posted by in categories: chemistry, energy, physics, satellites

Year 2015 😗😁

Physicists in France have figured out how to optimise an advanced type of electric rocket thruster that uses a stream of plasma travelling at 72,420 km/h (45,000 mph) to propel spacecraft forward, allowing them to run on 100 million times less fuel than conventional chemical rockets.

Known as a Hall thruster, these engines have been operating in space since 1971, and are now routinely flown on communication satellites and space probes to adjust their orbits when needed. These things are awesome, and scientists want to use them to get humans to Mars, except there’s one — rather large — problem: the current lifespan of a Hall thruster is around 10,000 operation hours, and that’s way too short for most space exploration missions, which require upwards of 50,000 hours.

MIT scientists have found a way to boil water more quickly and efficiently

Posted by in categories: chemistry, energy

What if water could be boiled more quickly and efficiently? It would benefit many industrial processes by reducing energy use, including most electricity generating plants, many chemical production systems, and even cooling systems for electronics.

Improving HTC and CHF

Now, MIT scientists have conceived of a method to do just that, according to a press release by the institution published on Tuesday. The researchers have found a way to improve at the same time the two key parameters that are conducive to the boiling process, the heat transfer coefficient (HTC) and the critical heat flux (CHF).
