It's not an ordinary cat video.

It's not an ordinary cat video.

NASA sends cat video 19 million miles away using laser rays. That technology means the LiFi or light-wifi is probably a next-generation communication tool. The system will revolutionize satellite data transmission. But this kind of light WiFi may operate as an everyday data network.

The biggest problem is how to transport information through walls and other hindrances. If there is a thing like a chair between the optical support station and the computer. That hindrance makes optical communication between the computer and its support station impossible.

Light-based communication is harder to jam and eavesdrop on than regular radio-based networks. The system can use aimed laser rays or diodes to transmit data. It is possible to use different color or wavelength LED or laser systems to create qubits or some kind of quantum computers.

That can operate at room temperature. The different color LEDs can make it possible to create a network system that shares information in different wavelengths. And that kind of network requires complex applications that can break into it. Light-based networks are far more secure than radio wave-based systems.

Precisely aimed IR and UV lasers are not very easy to break. And if the data transporter travels in another hollow laser ray the system sees the change in the laser ray's energy if somebody wants to put the meter in the laser ray.

The problem with the LiFi (Laser or light WiFI) is that the receiver must have visual contact with the transmitter during the network session. One solution could be that users use fixed workstations. But also mobile systems can use this kind of thing. In some visions of the future city hovers airchips that retransmit information that laser rays transmit to the right buildings. And inside the building small quadcopters can act as relay stations that allow users to move in that area.

The AI-based systems can read text from the screen and then send that request to the server. The system can use fixed surveillance cameras and a quadcopter combination. The quadcopter also works as a moving support-relay station. The system also makes it possible for the quadcopters that the system uses as relay stations can be right positions so that they can transmit and receive optical data all the time.

Limits of the LiFi are that the system cannot send data through walls and even paper can stop regular laser beams. But things like mirrors and holograms can help the system see the information visible in large sectors. The data transfer between rooms can happen through mirrors that are outside windows. And hologram paintings and other things can flash and transmit information.

The LiFi network's receiver can be a regular (or IR and UV) web camera. The system can operate by using support stations that use holograms or large-area laser rays and things like self-operating, small quadcopters that can use laser LEDs to communicate with computers. The quadcopter that can use wireless battery load can keep it in the right position with the computer. The computer can use LEDs connected to the computer itself. Or it's a USB port. In some visions computer can use its screen to transmit data.

The AI-based camera system in drones or action cameras in the user's bandanna can read texts from the screen. And then send the request to network operating servers to search for things. The system can use laser-LED groups that the quadcopters see. If the system requires light in the data. That the user sends to the network. And that makes this system fully optical.

That is visible to the optical sensor. Another thing that can make the Light-WiFi more practical is X-ray lasers. The X-ray lasers can transmit data through walls, but the problem is that those systems cause cancer.

The new bendable sensor is like straight from the SciFi movies.

"Researchers at Osaka University have developed a groundbreaking flexible optical sensor that works even when crumpled. Using carbon nanotube photodetectors and wireless Bluetooth technology, this sensor enables non-invasive analysis and holds promise for advancements in imaging, wearable technology, and soft robotics. Credit: SciTechDaily.com" (ScitechDaily, From Sci-Fi to Reality: Scientists Develop Unbreakable, Bendable Optical Sensor) The new sensor is like the net eye of bugs. But it's more accurate than any natural net eye. The system is based on flexible polymer film and nanotubes. The nanotubes let light travel through it. And then the film at the bottom of those tubes transforms that light into the image. This ultra-accurate CCD camera can see ultimate details in advanced materials. The new system can see the smallest deviation in the materials. And that thing makes it possible to improve safety on those layers. The ability to see ultra-small differences on surf

Quantum breakthrough: stable quantum entanglement at room temperature.

"Researchers have achieved quantum coherence at room temperature by embedding a light-absorbing chromophore within a metal-organic framework. This breakthrough, facilitating the maintenance of a quantum system’s state without external interference, marks a significant advancement for quantum computing and sensing technologies". (ScitechDaily, Quantum Computing Breakthrough: Stable Qubits at Room Temperature) Japanese researchers created stable quantum entanglement at room temperature. The system used a light-absorbing chromophore along with a metal-organic framework. This thing is a great breakthrough in quantum technology. The room-temperature quantum computers are the new things, that make the next revolution in quantum computing. This technology may come to markets sooner than we even think. The quantum computer is the tool, that requires advanced operating- and support systems. When the support system sees that the quantum entanglement starts to reach energy stability. I

Humans should be at the center of AI development.

"Experts advocate for human-centered AI, urging the design of technology that supports and enriches human life, rather than forcing humans to adapt to it. A new book featuring fifty experts from over twelve countries and disciplines explores practical ways to implement human-centered AI, addressing risks and proposing solutions across various contexts." (ScitechDaily, 50 Global Experts Warn: We Must Stop Technology-Driven AI) The AI is the ultimate tool for handling things that behave is predictable. Things like planets' orbiting and other mechanical things that follow certain natural laws are easy things for the AI. The AI might feel human, it can have a certain accent. And that thing is not very hard to program. It just requires the accent wordbook, and then AI can transform grammatically following text into text with a certain accent. Then the AI drives that data to the speech synthesizer. The accent mode follows the same rules as language translation programs. The ac
