NASA Maxwell X-57 all-electric aircraft made a thermal test for its cruise engines.

All electric aircraft are the tools that can revolutionize aviation. Electric engines can use to make aircraft silent. So the next-generation aircraft can use electric engines for lift-off from city areas and fly away from cities. Then they can start to use their jet engines. That thing can use to lower the noise that aircraft create. The "flying cars" or cheap VTOL (Vertical Take-off and Landing) aircraft can use by officials and private actors. The all-electric engine systems allow them to operate from any parking lots.

There is also the possibility that all-electric vehicles can also act as submarines. Today those "flying submarines" are small quadcopters that can operate in airborne and underwater conditions. But it's possible to create larger, manned models of those small drones.

If the electric-powered aircraft uses a wireless electric supply. There are no limits to the time that this system can operate. The system can create wireless power by using laser-aimed lighting. The electric-powered aircraft is not necessarily slow. Research teams in China, Russia, and the USA test the plasma-jet engines their electric arcs are making plasma. And then magnets are driving that plasma backward. The plasma-jet engines allow aircraft can travel even at hypersonic speed. And then the system can also use the remote energy supply without landing.

The plasma-jet engines also allow the "flying submarine" can fly at high-speed. The same engine and its magnetic track can use as MHD (Magnetic Hydrodynamic Drive). And the shape of that system can be a winged cigar that can operate airborne and underwater.

There created the idea that large-size quadcopters can use to rise jet aircraft from the ground and then fly them to the area there are no people. Then those helicopters simply drop that aircraft. And it will continue its flight by using jet engines. There are also plans for manned quadcopters that are using turning blowers. The winged quadcopter rises like all other quadcopters, and then it can turn its blowers backward. And that allows it to operate faster than regular helicopters.

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger. The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth. It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons. It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho...

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field. An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate. AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru...

The new observations and observation tools are revolutionizing nanotechnology and the way of thinking in physics.

ScitechDaily.com "A new study has overturned a fundamental principle of physics by demonstrating that similarly charged particles can attract each other in a solution, with the effect varying between positive and negative charges depending on the solvent. This discovery has significant implications for various scientific processes, including self-assembly and crystallization". (ScitechDaily, Opposites Attract, Likes Repel? Scientists Overturn Fundamental Principle of Physics) The research reveals the importance of solvent structure at the interface in determining interparticle interactions, challenging long-held beliefs and indicating a need for a re-evaluation of our understanding of electromagnetic forces.
