Renewable Energy Could Basically Be Free by 2030, According to New Analysis

Posted by in categories: economics, energy, sustainability

A research analyst at Swiss investment bank UBS believes the cost of energy renewables could be so near to zero by 2030 “it will effectively be free,” according to a projections published on Monday. If renewables could soon be cheaper than all the alternative energy sources, and that this “is great news for the planet, and probably also for the economy.”

The analysis, published in the Financial Times, explains that solar and wind farms are getting bigger, and that the potential of this sort of cheap, green energy is far-reaching and will only get cheaper. “In 2010, using solar power to boil your kettle would have cost you about £0.03,” the analyst writes in FT. “By 2020, according to estimates by our research team at UBS, the cost will have fallen to half a penny.” And just ten years later, the costs will be so minuscule, it will practically be free.

Terahertz technology creates new insight into how semiconductor lasers work

Posted by in categories: energy, futurism

Lasers are widely used as high power sources of light operating at a specific frequency. But how does this frequency get selected when a laser is turned on, and how quickly?

Pioneering engineers working with technology have been researching how individual frequencies are selected when a laser is turned on, and how quickly the selection is made.

The development of specific terahertz equipment has allowed them to investigate this process for the first time. Their results, published in Nature Communications, will underpin the future development of semiconductor lasers, including those used in public and private sector-owned telecommunications systems.

The behavior of water—scientists find new properties of H2O

Posted by in category: energy

A team of scientists has uncovered new molecular properties of water—a discovery of a phenomenon that had previously gone unnoticed.

Liquid water is known to be an excellent transporter of its own autoionization products; that is, the charged species obtained when a water molecule (H2O) is split into protons (H+) and hydroxide ions (OH). This remarkable property of water makes it a critical component in emerging electrochemical energy production and storage technologies such as fuel cells; indeed, life itself would not be possible if water did not possess this characteristic.

Water is known to consist an intricate network of weak, directional interactions known as . For nearly a century, it was thought that the mechanisms by which water transports the H+ and OH ions were mirror images of each other – identical in all ways except for directions of the hydrogen bonds involved in the process.

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.
