The Plasma Compression Fusion Device—Enabling Nuclear Fusion Ignition

Posted by in categories: engineering, military, nuclear energy, particle physics

The plasma compression fusion device (PCFD) generates the energy gain by plasma compression-induced nuclear fusion. This concept has the capability of maximizing the product of plasma pressure and energy confinement time to maximize the energy gain, and thus give rise to fusion ignition conditions. The preferred embodiment of this original concept uses a hollow cross-duct configuration of circular cross section in which the concentrated magnetic energy flux from two pairs of opposing curved-headed counter-spinning conical structures (possibly made from an alloy of tungsten with high capacitance) whose outer surfaces are electrically charged compresses a gaseous mixture of fusion fuel into a plasma, heated to extreme temperatures and pressures. The generated high-intensity electromagnetic (EM) radiation heats the plasma and the produced magnetic fields confine it in between the counter-spinning conical structures, named the dynamic fusors (four of them-smoothly curved apex sections opposing each other in pairs). The dynamic fusors can be assemblies of electrified grids and toroidal magnetic coils, arranged within a conical structure whose outer surface is electrically charged. The cross-duct inner surface surrounding the plasma core region is also electrically charged and vibrated in an accelerated mode to minimize the flux of plasma particles (including neutrals) from impacting the PCFD surfaces and initiating a plasma quench. The fusion fuel (preferably deuterium gas) is introduced into the plasma core through the counterspinning conical structures, namely, injected through orifices in the dynamic fusor heads. There is envisioned another even more compact version of this concept, which uses accelerated vibration in a linear-duct configuration (using two counterspinning dynamic fusors only) and would best be suited for fusion power generation on aircraft, or main battle tanks. The concept uses controlled motion of electrically charged matter through accelerated vibration and/or accelerated spin subjected to smooth, yet rapid acceleration transients, to generate extremely high-energy/high-intensity EM radiation (fields of high-energy photons) which not only confines the plasma but also greatly compresses itso as to produce a high power density plasma burn, leading to ignition. The PCFD concept can produce power in the gigawatt to terawatt range (and higher) with input power in the kilowatt to megawatt range and can possibly lead to ignition (selfsustained) plasma burn. Several important practical engineering and operational issues with operating a device such as the PCFD are discussed.

ABS Signs Teleport Deal with Telemedia

Posted by in categories: biotech/medical, computing, engineering, quantum physics

ABS is partnering with Telemedia, a broadcasting and teleport service provider in South Africa, to improve its service offerings to customers in the Middle East and Africa region (MEA). ABS announced Monday that the company will gain access to a full suite of telecom services provided by Telemedia at its Johannesburg teleport. Telemedia will provide teleport fiber connectivity, data center hosting, and satellite uplink capabilities.

Telemedia said the partnership enables the company to further expand its broadcast and satellite connectivity services in the MEA.

“Our collaboration with Telemedia reinforces and strengthens our presence in the MEA and provides an extension to our global connectivity network,” Ron Busch, ABS’ EVP Engineering and Operations said. “[Telemedia’s] infrastructure offering with a solid track record, excellent customer support and can-do attitude during the COVID-19 pandemic shows its commitment to excellent customer service.”

Lab-grown wood could let us grow furniture in a lab instead of in a forest

Posted by in categories: biotech/medical, engineering

“In a paper recently published the Journal of Cleaner Production, the researchers detail how they grew wood-like plant tissue from cells extracted from the leaves of a zinnia plant, without soil or sunlight. “The plant cells are similar to stem cells,” says Luis Fernando Velásquez-García, a principal scientist in MIT’s Microsystems Technology Laboratories and co-author of the paper. “They have the potential to be many things.” With the ability to “tune” the plant cells into whatever shape they decide, Ashley Beckwith, mechanical engineering PhD student and the paper’s lead author, says they could use this process to grow more efficient materials. “Trees grow in tall cylindrical poles, and we rarely use tall cylindrical poles in industrial applications,” she says. “So you end up shaving off a bunch of material that you spent 20 years growing and that ends up being a waste product.” Instead, their idea is to grow structures that are more practical, like rectangular boards or eventually an entire table that doesn’t need to be assembled, which would reduce waste and potentially let land currently used for logging instead be preserved as forest.”


Why cut down trees when you can grow wood in the exact shape you need?

Slowing Ageing — Joao Pedro Magalhaes- Prof University of Liverpool & Founder Magellan Science Ltd

Forever we have held a view that AGING, DISEASE & DEATH is an un-alterable eventuality, those who dared question were ostracised for playing God.

If you choose to look deeper you will surely be amazed. Bowhead whales live for over 200 yrs “Turriptosis Dohnri” is a Jellyfish that lives forever. Can these #genetics traits be replicated in humans? Could the removal of #senescence #cells that accelerates aging be the answer Is it even possible to control or reverse aging? Can we grow old healthily? 150000 die every day & over 100000 of them are caused by aging.

Researchers create new form of cultivated meat

Posted by in categories: biotech/medical, engineering, food

McMaster researchers have developed a new form of cultivated meat using a method that promises more natural flavor and texture than other alternatives to traditional meat from animals.

Researchers Ravi Selvaganapathy and Alireza Shahin-Shamsabadi, both of the university’s School of Biomedical Engineering, have devised a way to make by stacking of cultivated muscle and grown together in a lab setting. The technique is adapted from a method used to grow tissue for human transplants.

The sheets of living cells, each about the thickness of a sheet of printer paper, are first grown in culture and then concentrated on growth plates before being peeled off and stacked or folded together. The sheets naturally bond to one another before the cells die.

First Nanomaterial Developed That Demonstrates “Photon Avalanching” – Extreme Nonlinear Optical Behavior and Efficiency

Posted by in categories: biotech/medical, chemistry, engineering, nanotechnology, quantum physics

Researchers develop the first nanomaterial that demonstrates “photon avalanching;” finding could lead to new applications in sensing, imaging, and light detection.

Researchers at Columbia Engineering report today that they have developed the first nanomaterial that demonstrates “photon avalanching,” a process that is unrivaled in its combination of extreme nonlinear optical behavior and efficiency. The realization of photon avalanching in nanoparticle form opens up a host of sought-after applications, from real-time super-resolution optical microscopy, precise temperature and environmental sensing, and infrared light detection, to optical analog-to-digital conversion and quantum sensing.

“Nobody has seen avalanching behavior like this in nanomaterials before,” said James Schuck, associate professor of mechanical engineering, who led the study published today (January 132021) by Nature. “We studied these new nanoparticles at the single-nanoparticle level, allowing us to prove that avalanching behavior can occur in nanomaterials. This exquisite sensitivity could be incredibly transformative. For instance, imagine if we could sense changes in our chemical surroundings, like variations in or the actual presence of molecular species. We might even be able to detect coronavirus and other diseases.”

Avalanching processes—where a cascade of events is triggered by series of small perturbations—are found in a wide range of phenomena beyond snow slides, including the popping of champagne bubbles, nuclear explosions, lasing, neuronal networking, and even financial crises. Avalanching is an extreme example of a nonlinear process, in which a change in input or excitation leads to a disproportionate—often disproportionately large—change in output signal. Large volumes of material are usually required for the efficient generation of nonlinear optical signals, and this had also been the case for avalanching, until now.
