ARCA’s revolutionary aerospike engine completed and ready for testing

Posted by in categories: energy, space

ARCA Space Corporation has announced its linear aerospike engine is ready to start ground tests as the company moves towards installing the engine in its Demonstrator 3 rocket. Designed to power the world’s first operational Single-Stage-To-Orbit (SSTO) satellite launcher, the engine took only 60 days to complete from when fabrication began.

Over the past 60 years, space launches have become pretty routine. The first stage ignites, the rocket lifts slowly and majestically from the launch pad before picking up speed and vanishing into the blue. Minutes later, the first stage shuts down and separates from the upper stages, which ignite and burn in turn until the payload is delivered into orbit.

The Way We Get Power Is About to Change Forever

Posted by in categories: energy, mathematics

Solar and wind power are all about the batteries.


The age of batteries is just getting started. In the latest episode of our animated series, Sooner Than You Think, Bloomberg’s Tom Randall does the math on when solar plus batteries might start wiping fossil fuels off the grid.

Energy Dept Spends $33M to Harden Grid Against Network, Kinetic Attack

Posted by in categories: cybercrime/malcode, energy

The grants focus on improving grid resiliency during a cyberattack and speeding recovery.

The Energy Department announced a roughly $33 million investment Tuesday in seven projects aimed at securing the electric grid against cyberattacks, physical attacks and weather disasters.

The projects are designed both to make grid systems more secure against cyberattacks and to improve their ability to withstand a cyberattack, according to a department fact sheet.

3D-Printed Wind Turbine Blades Could Bring ‘Sci-Fi’ Level of Performance

Posted by in categories: 3D printing, energy, sustainability

(3Ders.org) The rapid advance of 3D printing technology means that hybrid-material wind turbine blades complete with metal mesh inserts are no longer the stuff of imagination. These energy savers with “sci-fi-level” performance could become reality in as soon as two years. Philip Totaro of Totaro & Associates, “The greatest challenge for wind turbine blade structural and manufacturing engineers is to implement the idealized performance and noise mitigated designs of aerodynamics engineers,” explains Totaro. “Limitations of previous generations of manufacturing technology and the reliance on lower cost materials have limited the type of spar/shear web structures which could be utilized.” But 3D printing could be about to change all that, Totaro says.

Monster Solar Flare Marks 7th Powerful Sun Storm in 7 Days

Posted by in categories: energy, space

The sun fired off yet another powerful solar flare yesterday (Sept. 10), its seventh in seven days.

The flare, which peaked at 12:06 EDT (1606 GMT), covered North and South America in high-energy light. The National Oceanic and Atmospheric Administration’s Space Weather Prediction Center (SWPC) released a statement that warned of strong, high-frequency radio blackouts and navigation-system disruption, potentially lasting up to an hour.

Like the six other flares observed since Sept. 4, this one came from a sunspot known as Active Region (AR) 2673, which is currently turning away from Earth and will soon be out of sight.

EU Funds 20 Million Euro ARM+FPGA Exascale Project

Posted by in categories: energy, supercomputing

At the Barcelona Supercomputer Centre on Wednesday (Sept. 6), 16 partners gathered to launch the EuroEXA project, which invests €20 million over three-and-a-half years into exascale-focused research and development.

Led by the Horizon 2020 program, EuroEXA picks up the banner of a triad of partner projects — ExaNeSt, EcoScale and ExaNoDe — building on their work to develop a complete HPC system based on ARM Cortex processors and Xilinx Ultrascale FPGAs. The goal is to deploy an energy-efficient petaflops system by 2020 and lay a path to achieve exascale capability in the 2022–23 timeframe.

All told, the European Commission is planning a €50 million investment for the EuroEXA group of projects, spanning “research, innovation and action across applications, system software, hardware, networking, storage, liquid cooling and data centre technologies.”
