Chemical-free, technology-based: A mosquito-free park in CHINA
In a park in Hangzhou, a smart mosquito control system has been implemented without the use of chemicals.
The traps mimic human body signals—heat, scent, and carbon dioxide—attracting mosquitoes and then killing them using air suction.
This technology offers an alternative to traditional urban pest control methods.
UFO ANTIGRAVITY FOR BEGINNERS:
a strong magnetic field B directly sources spacetime curvature through the EM stress-energy tensor.
R⁰⁰ ∝ B²
Integrate that curvature along the ship and you get a clean body-force acceleration α. No propellant. No reaction mass. The entire craft and everything inside it (crew included) is pushed uniformly by the curved spacetime itself — exactly like gravity, but engineered, directed, and controllable.
This is how you create artificial gravity or antigravity on demand. Point the curvature gradient one way and the ship accelerates at thousands of g with zero inertial stress on structure or people. Flip it and you hover motionless for hours. The surrounding air or water co-moves with the ship, so no sonic booms, no heat walls, no mode switches between atmosphere, vacuum, or ocean.
Pulse the B-field at high frequency N and α scales with B² × volume × N. Use the de Sitter-like term (controlled by vacuum expectation value ϕ₀) and you get perfectly constant acceleration with zero tidal forces inside — the crew feels only steady “weight” while the vehicle rips across the sky at relativistic potential.
This engine is just an advanced compact EM generator. It doesn’t fight gravity or inertia; it reshapes the spacetime metric so gravity-like acceleration appears wherever you want it.
Figure 3 shows the complete loop: B → curvature R⁰⁰ → body-force α → UAP-level flight performance.
Speculative? Yes — today’s magnets are far too weak and we haven’t built the ϕ₀ control yet. But the physics is pure GR + electromagnetism. If EEs ever crack the extreme-field engineering, this is how we stop using rockets and start using spacetime itself as the propulsion medium.
Mind-blowing how a magnetic field becomes antigravity.

Disco Corporation is a Japanese precision toolmaker with 5,491 employees. TSMC, Samsung, Intel, Nvidia, Apple, and every semiconductor company on Earth uses their machines. Every chip on the planet must be cut from its wafer and ground to final thickness before it can be packaged. Disco controls over 70% of the global market for wafer dicing saws and grinders. Their diamond blades cut silicon at 40,000 RPM with a kerf width of 20 microns. A human hair is 70. The blades are consumables. A single 300mm fab burns through thousands per year. Standard industrial cutting tools cost a few dollars each. Disco's precision dicing blades sell for hundreds of dollars apiece. At 20 microns, every fraction of a micron saved in cut width recovers sellable silicon on a $10,000 wafer. The company runs on a system called Will. There are no managers. Instead, employees bid on tasks using an internal currency. The CEO who built this system, Kazuma Sekiya, has said Disco does not chase growth for the sake of market share. The semiconductor industry comes to them.
