Methane could be a good source of hydrogen.

Methane gas (CH4) is one of the most interesting energy sources in the world. Bacteria make that gas from biomass. So that thing can make the mechanical cow possible. The mechanic cow means the system where inside the robot's stomach is the cell culture there are methane bacteria. That kind of robot can make energy from all types of biomass. 

In some visions, the mechanic sea cow or yacht can use internal methane bacteria cultures to create methane for its turbines. These kinds of systems can be new and powerful green energy systems. 

Methane is a good hydrogen source. But that requires a filter system that removes carbon from that molecule. 



Methane is a hydrocarbon gas that could quite easily filter. And if carbon is removed from the methane molecule. That gas could be a good and clean energy source. If we think that methane can use as an energy source in robotics, there are two ways to make that gas carbon neutral. 

The first way is to remove carbon from the methane. And in that process, the carbon filter removes the carbon from the methane molecule. Or in another version the exhaust gas can filter. 

And if the filter system could remove carbon. That makes methane a clean and good energy source. The methane bacteria can grow in the cell cultures. Then those bacteria can form methane, and that system could drive to the turbines or fuel cells. The only thing that methane bacteria requires is biomass that it uses as a nutrient. 



That kind of system can create hydrogen for turbines. That cell culture or nutrient can install in the vehicles like yachts. In that kind of system, all kinds of biomass can make biologically produced clean fuel if the system can remove carbon. And that thing would revolutionize engineering. The methane allows creating the robots and machines that are more independent and multifunctioning than ever before. Those robots can find their fuel from any kind of biomass.

Use virtual "perpetual motion machines" and seawater as energy sources.

   Use virtual "perpetual motion machines"  and seawater as energy sources.  The Archimedean screw can offer almost endless energy sources.  "Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving. It is widely credited as the first attempt to describe such a device." (Wikipedia/Perpetual motion) The term "virtual perpetual motion machine" means a machine. That pulls water to the upper tank using a capillary tube. Then that water will fall through the generator or turbine wheel. The machine uses differences in pressure levels. But it looks like a "perpetual motion machine", that is impossible because of laws of thermodynamics.  The machine uses differences in pressure levels. But it looks like a " real perpetual motion machine", which is impossible because of the laws of thermodynamics.  The real perpetual motion machines don't use outside energy. And that's why they are not possible....

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...
