Comparatively low-cost nuclear fusion project shows promise after first year of experiments

https://www.scmp.com/news/china/science/article/3155546/chinese-scientists-strike-early-gold-race-nuclear-fusion-power Via email: Fusion researchers everywhere want more money. Researchers at the Chinese Academy of Sciences began their experiments into fusion power last summer. However, the government gave the team just $156 million over 6 years. (The boondoggle) ITER in France will consume $45 to $65 billion (if not more). They wanted to improve on results at the US National Ignition Facility over the summer. So the team needed to figure out how to do it on a tiny budget and with less powerful lasers. Eventually, they turned to a process developed in 1997 by Z Jie, a renowned Chinese physicist. The method involves weaker laser beams aimed at two tiny gold cones. When hit by the lasers, each directs H plasma  toward the other. When the plasma beams collide with precisely the right parameters, fusion  occurs. While the gold cones vaporize after fusion, the cost will be “e...

Tiny chip provides a big boost in precision optics

https://www.rochester.edu/newscenter/new-photonic-chip-boosts-precision-optics-501802/ Via email: By merging beams of reflected light, an interferometer creates an interference pattern that provides remarkably detailed information about the objects illuminated. "If you want to measure something with very high precision, you almost always use an optical interferometer, because light makes for a very precise ruler. The tiny new chip amplifies the signal without a corresponding increase in noise. In this device only certain photons that contain needed information are directed to the detector. While done before, "it's always with a large setup on a table, a bunch of mirrors and laser systems, all very painstakingly aligned," This large setup was distilled and put into a photonic chip. "And by having the interferometer on a chip, you can put it on a rocket, helicopter, or your phone—and it will never become misaligned." Instead of using a set of tilted mirrors ...

Tiny crystal at a distance safely measures powerful electric fields

https://newsreleases.sandia.gov/remote_sensor/ Via email: Lithium niobate crystal + polarized laser light---> extreme voltage measurements at a distance! Even the best voltmeters available today will melt at extreme voltages. "No one had directly measured voltages this large anywhere in the world before our experiment. "...the technique is safe, efficient and inexpensive." The lithium niobate crystal is placed so that the EM field passes through its broadside at right angles to the polarized laser beam traveling along the crystal's axis. The EM field causes the polarized beam photons to travel at different speeds in the vertical and horizontal directions. This causes the beam to rotate which in turn alters the number of photons arriving at a photodetector. An instrument converts their intensity at the photodetector into a simple voltage. That simple voltage can then be read on an everyday oscilloscope. "The voltage measured on the oscilloscope is directly (p...

The recycling cost for 1 kg solar cell with this process is estimated at $68.9 and the total profit after recycling a 1 kg solar cell is calculated to be $185.4... also said to enable the recovery of aluminum, silver, and lead as aluminum hydroxide, silver chloride, and lead oxide, respectively" Related: Solar panels: we need to recycle parts of them to use again and avoid a mountain of waste https://techxplore.com/news/2021-11-solar-panels-recycle-mountain.html Recyclable, back-contact solar panel from the Netherlands https://www.pv-magazine.com/2021/12/09/recyclable-back-contact-solar-panel-from-the-netherlands The surprising appliance that could make solar panels easier to produce and recycle https://www.anthropocenemagazine.org/2023/04/the-surprising-appliance-that-could-make-solar-panels-easier-to-produce...

Need for larger space telescope inspires lightweight flexible holographic lens

https://news.rpi.edu//content/2021/10/21/need-massive-space-telescope-inspires-lightweight-flexible-holographic-lens Very big development for the future of space telescopes... "lightweight flexible lens, many meters in diameter, that could be rolled for launch and unfurled in space... We use two spherical waves of light to produce the hologram, which gives us fine control over the diffractive grating recorded on the film, and the effect it has on light — either separating light with super sensitivity, or focusing light with high resolution" Related: Researchers devise new membrane mirrors for large space-based telescopes https://www.optica.org/en-us/about/newsroom/news_releases/2023/april/researchers_devise_new_membrane_mirrors_for_large/ Condor telescope reveals a new world for astrophysicists https://phys.org/news/2024-03-condor-telescope-reveals-world-astrophysicists.html Ultrablack thin-film coating could make next-gen telescopes even better https://phys.org/news/2024-03-...
