Quantum Mechanical Mass mechanism ~ Why Mass increases

Posted by in categories: energy, quantum physics

It is important to have a mechanism that forms Mass, because if we had a concept of how Mass is formed it would give us a deeper understanding of gravity and help us unity Relativity and Quantum Mechanics.

In this theory Mass increases with speed, because Photon ∆E=hf energy is continuously transforming potential energy into the kinetic energy of matter in the form of electrons.

Tesla Megapacks to back energy facility in this South American country

Posted by in categories: energy, sustainability

Tesla’s Megapack grid-scale storage systems have been selected for yet another solar energy and storage project, this time set to be installed in Chile.

Chilean energy storage developer Colbún has announced plans to install over 200 Tesla Megapacks as part of the 228 MW/912 MWh Celda Solar project in the northern part of the country, as detailed in a press release shared this week. The site will be constructed in the Camarones, Arica and Parinacota region, and the company estimates the total cost to be around $260 million.

“Energy storage will play an increasing role in the Chilean electricity system, allowing solar energy generated during the day to be accumulated and supplied to the system at night,” writes José Ignacio Escobar, Colbún CEO, as translated into English from Spanish. “Our energy stored in the reservoirs in the south complements perfectly with the energy that we will store in our batteries in the north, thus having a safe, diversified and competitive offer for our clients from Arica to Puerto Montt.”

Scientists discover genetic blueprint that could revolutionize global food production: ‘More productive and resilient crops for the future’

Posted by in categories: energy, food, genetics

To harness the power of the sun and make sugars for energy storage, plants use photosynthesis. But some plants are more efficient at it than others. For the first time, researchers have identified a key step in the transformation between old-fashioned C3 photosynthesis and new and improved C4 photosynthesis — which could lead to the development of more efficient, more resilient “super crops,” SciTechDaily reports.

Scientists at the Salk Institute in San Diego, California, collaborated with researchers at the University of Cambridge to make the breakthrough, charting the evolution of plants over millions of years.

Thermal evaporation emerges as a promising strategy for scalable solid-state battery production

Posted by in categories: energy, sustainability, transportation

Solid-state lithium batteries are promising energy storage solutions that utilize solid electrolytes as opposed to the liquid or gel electrolytes found in traditional lithium-ion batteries (LiBs). Compared to LiBs and other batteries that are used worldwide, these batteries could attain significantly higher energy densities of more than 500 Wh/kg−1 and 1,000 Wh/l−1, which could be advantageous for powering electric vehicles and other electronics for longer periods of time.

Despite their possible advantages, existing solid-state lithium batteries exhibit significant limitations that have so far prevented their large-scale deployment. These include the active lithium loss that can occur while the batteries are charged and discharged, which can reduce their efficiency and overall performance.

This loss of lithium is caused by an inhomogeneous lithium plating. Devising effective strategies and thin lithium metal foils that could limit the loss of lithium in solid-state batteries is thus a key goal for the energy research community.

Dual Lasers Lead to High-Energy LPA and View of Laser-Plasma Interaction

Posted by in category: energy

BERKELEY, Calif., Dec. 19, 2024 — Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) used lasers and a supersonic sheet of gas to accelerate a high-quality beam of electrons to 10 billion electronvolts (eV) in just 30 cm. The energy and quality of the beam is a significant improvement compared to previous efforts.

UN report says 1.1 billion people living in acute poverty

Posted by in categories: education, energy

Child mortality in conflict settings was 8 percent, compared with 1.1 percent in peaceful countries.

It also said that 83.2 percent of the world’s poorest people live in sub-Saharan Africa and South Asia.

The index, compiled jointly with the Oxford Poverty and Human Development Initiative (OPHI), used indicators such as a lack of adequate housing, sanitation, electricity, cooking fuel, nutrition and school attendance to assess levels of “multidimensional poverty”

What Is Entropy? A Measure of Just How Little We Really Know

Posted by in categories: energy, finance, military, physics, space

The notion of entropy grew out of an attempt at perfecting machinery during the industrial revolution. A 28-year-old French military engineer named Sadi Carnot set out to calculate the ultimate efficiency of the steam-powered engine. In 1824, he published a 118-page book(opens a new tab) titled Reflections on the Motive Power of Fire, which he sold on the banks of the Seine for 3 francs. Carnot’s book was largely disregarded by the scientific community, and he died several years later of cholera. His body was burned, as were many of his papers. But some copies of his book survived, and in them lay the embers of a new science of thermodynamics — the motive power of fire.

Carnot realized that the steam engine is, at its core, a machine that exploits the tendency for heat to flow from hot objects to cold ones. He drew up the most efficient engine conceivable, instituting a bound on the fraction of heat that can be converted to work, a result now known as Carnot’s theorem. His most consequential statement comes as a caveat on the last page of the book: “We should not expect ever to utilize in practice all the motive power of combustibles.” Some energy will always be dissipated through friction, vibration, or another unwanted form of motion. Perfection is unattainable.
