US Army moves ahead with development of 100-kW mobile battlefield laser

Posted by in categories: energy, military

The US Army is moving forward with a new 100-kW laser weapon, awarding US$10 million to Lockheed Martin and Dynetics to continue development of the High Energy Laser Tactical Vehicle Demonstrator (HEL TVD). Designed to counter low cost, high volume threats, the new mobile battlefield laser is the latest in the American effort to produce incrementally more powerful and accurate directed energy weapons.

The potential impact of electric vehicles on global energy systems

Posted by in categories: energy, transportation

Electric vehicles are unlikely to create a power-demand crisis but could reshape the load curve. Here’s how to bend that curve to your advantage.

Could electric vehicles (EVs) soon face a different kind of gridlock? With the electrification of mobility accelerating, energy producers and distributors need to understand the potential impact of EVs on electricity demand (Exhibit 1). The good news: McKinsey analysis suggests the projected growth in e-mobility will not drive substantial increases in total electrical-grid power demand in the near to midterm, thus limiting the need for new electricity-generation capacity during that period.

Tesla’s production problems extend to its solar roof business, too

Posted by in categories: business, Elon Musk, energy, sustainability, transportation

The production problems Tesla has faced with its Model 3 have been well documented. Now, sources say the company is facing similar issues with its solar roof tile initiative. According to Reuters, former and current employees have revealed that assembly line problems, plus CEO Elon Musk’s exacting aesthetic demands, has delayed production, causing tension with partner Panasonic, and rattling officials that are keen to see a return on significant state investment.

The “Solar Roof,” produced at Tesla’s factory in Buffalo, New York, is designed to look like and function as a regular roof while also generating energy. According to sources, technical challenges have delayed production, as has Musk’s design plans. Speaking to Reuters, one source said that “Aesthetic look is the key point that Elon is not always satisfied with. That’s the big issue.”

Neither Tesla nor Reuters’ sources have revealed current production figures for the roof tiles, but the delays are such that Panasonic — which the initiative depends on for solar components — has been forced to find other buyers for the parts it had built to sell to Tesla. According to a former Panasonic employee, the company has been shipping “large volumes” of its photovoltaic cells as samples to other prospective buyers, due to low demand from Tesla. Panasonic declined to comment on the issue, stating only that it “believes Tesla will use Panasonic cells when it mass-markets the Solar roof.”

Scientists Discover the Great Pyramid of Giza’s Design Can Concentrate Electromagnetic Energy

Posted by in categories: energy, physics

Researchers from St Petersburg’s ITMO University in Russia and Laser Zentrum Hannover in Germany have discovered a fascinating phenomenon regarding the design of the Great Pyramid of Giza.

A theoretical investigation published in the Journal of Applied Physics on July 20 2018 reveals the chambers within the Great Pyramid can “collect and concentrate electromagnetic energy.” Scientists looked at the “excitation of the pyramid’s electromagnetic dipole and quadrupole moments,” or the combinations of outgoing and incoming electromagnetic waves, to determine its capacity for electromagnetic focus. Using numerical simulations to deduce their findings, the research team found that under certain conditions, the pyramid’s internal chambers and the area under its base (where the third, unfinished chamber is located) can concentrate this energy.

Modern physics has provided unprecedented insight into the secrets of the pyramids, which were constructed around 2560 BC. For instance, cosmic ray-based imaging (also known as muon tomography) has been used to see further into the depths of these ancient structures, illuminating a previously unknown “large void” that humans haven’t encountered in several millennia.

Coordinated ocean energy efforts herald a new industrial sector

Posted by in categories: energy, sustainability

Despite its remaining mystery, the ocean is a complex working environment, widely used for fishing, shipping and recreation; but so far largely untapped for energy generation. OCEANERA-NET seeks to give the industry the boost it needs.

The European Union coastline runs to around 66 000 kilometres. This vast stretch holds a largely unexploited potential for ocean generated electricity, calculated to be around 380 GW by DG MARE (the EU Directorate responsible), constituting a significant contribution to the EU’s 2020 targets for .

Presently, there are a number of Member States funding research and development into ocean energy technology. However, these efforts are not coordinated and so not the game-changers they could be.

New geometric shape used by nature to pack cells efficiently

Posted by in category: energy

These cells pack together tightly. To accommodate the curving that occurs during embryonic development, it has been assumed that epithelial cells adopt either columnar or bottle-like shapes.

However, a group of scientists dug deeper into this phenomenon and discovered a new geometric shape in the process.

They uncovered that, during tissue bending, epithelial cells adopt a previously undescribed shape that enables the cells to minimize energy use and maximize packing stability. The team’s results will be published in Nature Communications in a paper called “Scutoids are a geometrical solution to three-dimensional packing of epithelia.”
