DENVER, July 11, 2018 /PRNewswire/ — Lockheed Martin (NYSE: LMT) has embraced a 3D printed titanium dome for satellite fuel tanks so big you can’t even put your arms around it. The 46-inch- (1.16-meter-) diameter vessel completed final rounds of quality testing this month, ending a multi-year development program to create giant, high-pressure tanks that carry fuel on board satellites.

The titanium tank consists of three parts welded together: two 3D printed domes that serve as caps, plus a variable-length, traditionally-manufactured titanium cylinder that forms the body.

One of the biggest freshwater reservoirs in the world is, literally, up in the air.

Between 6 and 18 million gallons of freshwater hover above every square mile of land, not counting droplets trapped in clouds. Scientists realized this centuries ago but they have never quite figured out how to bring the water down to earth. The effort required to condense it would consume such vast quantities of energy that it has always appeared to make any effort to capture and use this water uneconomical.

Directly converting electrical power to heat is easy. It regularly happens in your toaster, that is, if you make toast regularly. The opposite, converting heat into electrical power, isn’t so easy.

Researchers from Sandia National Laboratories have developed a tiny silicon -based device that can harness what was previously called waste heat and turn it into DC power. Their advance was recently published in Physical Review Applied.

“We have developed a new method for essentially recovering energy from waste heat. Car engines produce a lot of heat and that heat is just waste, right? So imagine if you could convert that engine heat into electrical power for a hybrid car. This is the first step in that direction, but much more work needs to be done,” said Paul Davids, a physicist and the principal investigator for the study.

This turbine can charge your USB device anywhere. 😀

Uranus really is strange. Not only does it rotate on an axis that sits at a 98-degree angle to its orbital plane, but, unlike the other giant planets, it doesn’t appear to release more heat than it receives from the Sun. Its magnetic field, too, appears warped compared to the Earth’s. An impact could perhaps help explain some of these strange traits.

Scientists have been simulating giant impacts into Uranus since the early 1990s, according to the new paper published in the Astrophysical Journal. This time around, researchers built a new simulation with the newest and best available data of the planet’s composition. This allowed them to model how a giant impactor, perhaps one to three times the mass of Earth, would have deposited “material and energy inside Uranus” and how much debris would be left over, from which moons could form.

“This study provides some great new insights into what might have happened all those billions of years ago, with material left over from the impact possibly even serving to trap some of that heat inside,” Leigh Fletcher, Royal Society Research Fellow at the University of Leicester, told Gizmodo.

The advantages of flow batteries include easy scalability and long cycle life. Among its disadvantages are relatively low energy density and high component cost.

Form Energy’s use of sulfur, which is both cheap and abundant, lowers those costs dramatically.

Geospatial analysis shows that ‘mini-grids’ would be the cheapest technology to provide universal electricity access by 2030.

Achieving universal access to electricity is essential for solving many global development challenges. Decentralized renewable energy technologies have emerged as a viable solution. Small, clean energy utilities called mini-grids are a key piece of the puzzle. They are community-based grids that generate and distribute power at the point of consumption. And they could be the most cost-effective way to deliver access to more than a third of the 1.1 billion people across the world who still lack any electricity supply, according to new analysis by the International Energy Agency (IEA).

Yet mini-grids are still largely an afterthought for many governments and their financial backers in Africa and Asia. Evidence strongly suggests that this mindset must change if the world is to achieve Sustainable Development Goal (SDG) 7 – access to modern, affordable, clean and reliable energy for all by 2030.

A California utility is seeking permission to have a company build the world’s largest battery, joining a growing list of power companies investing in storing electricity.

Pacific Gas & Electric Co., part of PG&E Corp., detailed plans for four storage projects totaling nearly 570 megawatts in a Friday filing to regulators, including a 300-megawatt battery installation at a natural-gas-fired power plant owned by Vistra Energy Corp.
