 The new nanotechnology can make it possible to create new types of electric systems, computers, and sensors. 


The new nanotechnology can make many things like clean water or create energy even for larger-scale systems. The new tiny nanomachine or nanodevice uses so-called Coulomb drag to create electricity. The Coulomb drag is the tool that can make nanomachines operate in the dark. And in some visions of the future. There is a large group of nanomachines that can float on the surface. Then those systems can detect things like chemicals, or they can be used to send electricity wirelessly into small flying drones. Or those small drones can land in the sea, and fill their electric load. 



The drawing shows how this system works. The thing is that nanotechnology can be used in large-scale entireties. Even full-scale submarines can use these engines. In those systems, large groups of nano- or small-size generators create electricity for electric engines. So in some models, the submarine shell is filled with nano-size systems that are rotating generators. Also, they can rotate small-size propellers that can drive water from the nose to the tail. That kind of system can be the modern version of the paddle steamer. The paddles would be even smaller than a millimeter. 


Nanotechnology is one of the tools that have multiple uses. The problem with those systems is that they need electricity. The floating nanomachine groups can also act as modular supercomputers. Modular supercomputers are the ultimate tools. And they are less vulnerable to damage than monolithic systems. If some parts of that system are damaged. 

The operators can just replace them with other parts. The idea for a floating nanomachine group that can make its missions is taken from mosquito larvae. Those insects float at the water's surface. The floating nanomachines or nanorobots can perform many different missions if they can operate as a large group. The nanomachine group floats just under the surface. And when it gets orders some of those machines dive to make their mission while others keep contact with them. Communication can happen acoustically or in laser light.

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
