The moon is sprinkled with patches of frozen water, NASA scientists discovered. Mining it may be crucial for travel to Mars and beyond
Posted by Raphael Ramos in categories: energy, space
So they’re planning to turn the moon water into rocket fuel. And the moon is now a stepping stone to Mars.
NASA is also planning to send a rover to moon’s south pole on 2022. 😃
Interesting.

General Atomics and Boeing team up on high-energy laser weapon
Posted by Quinn Sena in categories: energy, military, space
General Atomics Electromagnetic Systems (GA-EMS) and Boeing have entered into a partnership to develop a scalable 100 kW to 250 kW-class High Energy Laser (HEL) weapon system for air and missile defenses.
Laser weapons have been high on the wish lists of major military powers ever since the first laser was invented by Theodore Maiman at the Hughes Research Lab, Malibu, California in 1960. With enough concentrated power to burn through steel, enough range to cover literally astronomical distances, an operating cost of a dollar a shot, and an unlimited number of shots so long as there’s power available, the laser looked like the so-called ultimate weapon – if it could be made practical.
Of the problems that have hampered laser weapon development over the past six decades, one of the biggest is how to properly cool a laser generator. This is important because weapon-grade lasers have an efficiency between 50 and 70 percent, with the leftover percentages being lost as heat that could shut down or damage the device.

Ecological Power Storage Battery Made of Vanillin, the Main Flavor Component of Vanilla
Posted by Quinn Sena in categories: energy, sustainability
Researchers at TU Graz have found a way to convert the aromatic substance vanillin into a redox-active electrolyte material for liquid batteries. The technology is an important step towards ecologically sustainable energy storage.
It is ground-breaking in the field of sustainable energy storage technology,” says Stefan Spirk from the Institute of Bioproducts and Paper Technology at Graz University of Technology. He and his team have succeeded in making redox-flow batteries more environmentally friendly by replacing their core element, the liquid electrolyte, which are mostly made up of ecologically harmful heavy metals or rare earths – with vanillin, an important ingredient of Austrian vanilla croissants.

Tesla Worldwide Microgrid Energy Storage Business Is Bigger Than You Thought
Posted by Raphael Ramos in categories: business, economics, energy
Featured image: TransAlta / Twitter One of Tesla’s main goals is the deployment of energy generation and storage systems. These microgrids can provide electricity to homes, relieving our dependence on a mine-and-burn hydrocarbon economy. Tesla currently has over 120 operational microgrids around the world, which is an excellent confirmation of the company’s success in achieving its goals.

You’ve Heard of Vantablack. Scientists Just Created ‘Super White’, And It’s Very Cool
Posted by Shane Hinshaw in categories: energy, materials
Scientists have created a super white paint that is the yin to Vantablack’s yang.
While ultra black materials can today absorb more than 99.96 percent of sunlight, this new super white coat can reflect 95.5 percent of all the photons that hit it.
Instead of warming up under direct light, objects painted with this new acrylic material can remain cooler than their surrounding temperature even under the Sun, which could allow for a new energy-efficient way to control temperature inside buildings.

It’s Official: Solar Is the Cheapest Electricity in History
Posted by Montie Adkins in categories: energy, finance, sustainability
Just a matter of time.
In a new report, the International Energy Agency (IEA) says solar is now the cheapest form of electricity for utility companies to build. That’s thanks to risk-reducing financial policies around the world, the agency says, and it applies to locations with both the most favorable policies and the easiest access to financing. The report underlines how important these policies are to encouraging development of renewables and other environmentally forward technologies.
☀️ You love renewable energy. So do we. Let’s nerd out over it together.

Spinach Gives Fuel Cells a Power Up
Posted by Raphael Ramos in categories: energy, food
Didn’t Popeye always say to eat your spinach?
You may want to add it to your fuel cells too!
Spinach-based catalysts could power fuel cells more efficiently than traditional platinum ones.
