The use of hydrogen in the propeller-aircraft opens new roads for manned, and unmanned systems.

The H2FLY aircraft

The RTG (Radio Thermal Generator) would be an extremely good power source for propeller aircraft. The problem in that solution is the highly radioactive isotope that can deliver to nature if that aircraft fill is fall from the ground. The RTG is easy to install on drones. And it can give electricity to electric motors that rotate the propellers of the drone and give it virtually unlimited operational time and range.

The German experimental hydrogen-using drone has reached 2203 meters altitude. The startup company H2FLY created that system. The hydrogen-powered fuel-cell-based propeller drone systems can use oxygen that they are taking from the air.

Or they can use hydrogen tanks. Hydrogen is easy to get if somewhere is an electricity city. The electrolysis chamber is easy to install in the body of the drone or manned aircraft. So the system can create hydrogen from the water that is put in that chamber.

The solar panels and power cells can also give an extremely good range for electric aircraft. The solar panels that are installed on the body and wings of the aircraft can rotate the electric engines and propellers by giving electricity straight to the electric engines. Or they can use electricity to break water molecules in the electrolysis chambers. So in that case, the system needs only water in the tank. And then the electrolysis breaks it into hydrogen and oxygen.

Of course, hydrogen-oxygen fuel cells can use by loading oxygen and hydrogen into the tank. That kind of system can be used, in the next-generation drone technology. The electrolysis system can use any power source. And that thing can be useful in the drones that are operating in conditions where is no petroleum.

This kind of drone can also deliver electricity to mobile devices of the ground operators. But the hydrogen-oxygen fuel cells can make drones silent. So the next-generation drones like Turkish Akinci drones can operate from the mobile fields where the electricity can take from the solar panels or sockets. Or even the car engines can give enough power that the drone can operate.

The LK-99 could be a fundamental advance even if it cannot reach superconductivity in 400K.

The next step in superconducting research is that LK-99 was not superconducting at room temperature. Or was it? The thing is that there is needed more research about that material. And even if it couldn't reach superconductivity in 400K that doesn't mean that material is not fundamental. And if LK-99 can maintain its superconductivity in 400K that means a fundamental breakthrough in superconducting technology. The LK-99 can be hype or it can be the real thing. The thing is, anyway, that high-voltage cables and our electric networks are not turning superconducting before next summer. But if we can change the electric network to superconducting by using some reasonable material. That thing can be the next step in the environment. Superconductors decrease the need to produce electricity. But today cooling systems that need lots of energy are the thing that turn superconductors that need low temperatures non-practical for everyday use. When the project begins there is lots of ent

Black holes, the speed of light, and gravitational background are things that are connecting the universe.

Black holes, the speed of light, and gravitational background are things that are connecting the universe. Black holes and gravitational waves: is black hole's singularity at so high energy level that energy travels in one direction in the form of a gravitational wave. We normally say that black holes do not send radiation. And we are wrong. Black holes send gravitational waves. Gravitational waves are wave movement or radiation. And that means the black holes are bright gravitational objects. If we can use water to illustrate the gravitational interaction we can say that gravitational waves push the surface tension out from the gravitational center. Then the other quantum fields push particles or objects into a black hole. The gravitational waves push energy out from the objects. And then the energy or quantum fields behind that object push them into the gravitational center. The elementary particles are quantum fields or whisk-looking structures. If the gravitational wave is

The CEO of Open AI, Sam Altman said that AI development requires a similar organization as IAEA.

We know that there are many risks in AI development. And there must be something that puts people realize that these kinds of things are not jokes. The problem is how to take control of the AI development. If we think about international contracts regarding AI development. We must realize that there is a possibility that the contract that should limit AI development turns into another version of the Nuclear Non-Proliferation Treaty. That treaty didn't ever deny the escalation of nuclear weapons. And there is a big possibility that the AI-limitation contracts follow the route of the Nuclear Non-Proliferation Treaty. The biggest problem with AI development is the new platforms that can run every complicated and effective code. That means the quantum computer-based neural networks can turn themselves more intelligent than humans. The AI has the ultimate ability to learn new things. And if it runs on the quantum-hybrid system that switches its state between binary and quantum states,
