The new devices are traveling in deep oceans.

The problem with small robots that patrol the ocean and measure pollution and other things is their power source. Nuclear power or RTG (plutonium batteries)  is a powerful tool. But those things are dangerous in the wrong hands. Things like nuclear submarines could load electricity to the photovoltaic cells of those machines by using lasers. But the problem is that navy might want to use their nuclear-powered submarines for many other purposes. 

The new algae-powered soft devices can be fundamental in the research of independently operating nano- and miniature machines. One of the biggest problems with independently operating nanomachines is the power source. The system can use synthetic, lab-grown muscle cells. 

They are connected to tiny electric wires. And nanotechnical microchips are not using very much energy. The problem is how to make those tiny machines operate in deep dark places. 

And one of the solutions is to use bioluminescence. In that case, the miniaturized microchips get their energy from the small photovoltaic cells. They are getting light from living bioluminescence cells. And also if lab-grown neurons are connecting with the microchips. They are increasing the power of those systems. The nanotechnical microchips don't need very much energy. And the thing that requires electricity in those half-biological robots is the control system. The living cells need only nutrients. 

Also, things like piezo-electric and thermo-electric crystals can give electricity to small machines. In those cases the main system gets its electricity from crystals that are stressed by using sonar signals or the heat from muscle cells can use for that thing. Living tissue can use normal nutrients. 

By the way...

Bigger robots like small ball-shaped quadcopters can also patrol the ocean and use green energy. In that kind of system, the robot can use solar power. When the batteries of those systems end while the robot operates in the sea it can simply rise to the surface. And the robot can wait until the sun loads its batteries. 

Then the system can send a GPS signal to a satellite that tells the communication system and command center that their robot is ready for action. The system can store data in the flash memory and send it to the command center. But there is a possibility that the system just uses a vertical tube into the ocean. And then the capillary effect puts the small generator to rotate.

Which one is better F-35 or the Su-57?

F-35 Lightning II

The thing is that the development of new concepts is not a very easy mission. At least, if that concept travels over Mach 2. The problem with jet fighters or multi-role jet fighters is that they are much more than some aerodynamic bodies. Things like computers, computer programs, and other kinds of things must operate in a very highly complicated entirety. 

If there are some kind of errors in those systems and their cooperation. That thing can cause destruction. The artificial intelligence that controls weapon systems and avionics should make these kinds of things more complicated than ever before. 

In manned aircraft, artificial intelligence can deny the aircraft touch ground in low-level flight. The radar- or lidar-based altimeter, along with the AI-boosted computer keeps the aircraft over the ground. If the flight altitude is only a couple of meters. So the AI fixes errors that the pilot can make. It can detect incoming missiles and start counter-actions if the pilot doesn't notice them. 

When we think of the Su-57, it can be very capable against old fashion jetfighters like F-16, Panavia Tornado, or F/A-18. But the thing is that those old-fashion-looking aircraft can also have updates like AI-based avionics or fire control. 

The reality is that capacity of the Su-57 will be seen only when it faces some jet fighter in air combat. And another thing that means in those situations is the pilot's skills and also how the jetfighter can operate with its support teams like air defense.

Su-57

"Black Swan" in air combat. When extremely extraordinary situations give wrong signals. 

When we look at history. The first British aircraft that dropped Messerschmitt Bf-109 in air combat was the Fairey Battle. The Fairey Battle was not a very big success. And maybe that was the only case when that aircraft dropped another aircraft. 

The detail of that case was that the rear-gunner of Fairey Battle dropped that Messerschmitt. But that victory was the first RAF air victory in WWII. If we look only at that case we might believe that Fairey Battle was a good combat aircraft. It was not a good plane at all. It served as a training aircraft and target tug in WWII. 

If we want to compare that case with something ordinary we can take a case where the goalkeeper of the ice-hockey team makes the goal. We always remember that kind of goal because they are extraordinary.  We don't even remember, was that team won or lose that match, or who made other goals. Those other goals are ordinary things. But that only goal that the goalkeeper made is what we remember. And the reason for that is that goal was extraordinary. 

Fairey Battle had been withdrawn from service in 1940. But that case shows that we should not make generalizations by using one example. That means that the "Black Swans" or extremely good luck can give false signals from the aircraft's capacities or some other equipment. 

There are billions of things that can go wrong in combat between two aircraft. The pilot can simply make mistakes and fly straight to the front of other aircraft or impact the ground. Or some hydraulic tubes can come off. Because somebody forgot tight the connector.

Time machine and the mechanics behind it.

Time travel to the future is quite a simple thing. We must just accelerate the object to the speed of light. And that thing stops time. So how to travel backward in time? One version is simple. The speed just stops the time in a capsule and waits until the sun erupts as a nova. That energy tsunami will send that hypothetical time machine back in time. 

Another way to make an energy tsunami is to make the craft travel at about 99% of the speed of light. And then detonate antimaterial inside it. That system can increase the energy level of the craft to the level that it virtually crosses the speed of light. 

In some visions, saucer-shaped craft would have a particle accelerator on its edge. Then the speed of those particles will reach the speed of light the antimatter annihilation will increase the energy level of that craft to the level that it virtually crosses the speed of light. And that thing causes the opposite time dilaton. 

The idea of the famous time machine of H.G Wells is a very simple thing. The rotating plate causes time dilation in the system. And then the time machine can go forward in time. When we are thinking about the system that will rotate at about 90-99% of the speed of light, that system can almost stop time inside it. So how to put the time machine traveling back in time? 

If our theoretical time traveler can stop time in the time machine that person can simply wait until the Sun is grown into a red giant. And finally when the Sun will erupt as nova the energy tsunami that comes from the star will push the time machine back in time. 

Above is the train to the future. Theoretically is possible to make the hyper-loop type train that travels in vacuum. The train will accelerate to the speed of light by using magnetic track. So the system is like particle acceleator. 

That kind of system could make train travel so fast that time inside it stops. To return to the past, the system must just create a situation where the train will virtually cross the speed of light. 

When it's time to travel back in time the system injects antimatter and material inside the chamber that is inside the train. That increases its energy to a level that the train starts to travel backward in time. 

There is the possibility, that our hypothetical time traveler could stop time in the machine by using two-way rotating plasma fields where the sum of the speeds of those plasma fields is higher than the speed of light. And that kind of thing allows traveling back in time by crossing the speed of light virtually. 

That thing is possible to make the Tipler cylinder which is multiple layers. When the cylinder's speed is near the speed of light the plasma starts to rotate between those layers. It can make it possible to travel back in time. 

Same way, we could make the spacecraft travel speed that is as close to the speed of light as possible. If the craft's speed is about 99% of the speed of light, that system can fly through the laser or radio waves that increase its energy so high that it turns into a black hole. 

Or it starts to travel back in time. Time travel base is on the idea of time dilation that is proven. If the object's speed is the same as the speed of light that thing stops time. And then if particles cross the speed of light. That thing means time starts to travel backward. 

The speed of light is crossed every day. The reason for the blue sky is Cherenkov's radiation. Cherenkov's radiation forms when particles that come from outer space with the speed of light slow their speed when it arrives in the medium. The speed of light is higher in a vacuum than in a medium. 

And when a particle hits the atmosphere. It releases its energy in form of radiation. During small moments the particle travels faster than the speed of light. The reason for that is: that anything that has mass cannot slow with unlimited speed. So during the slowing time particle sends radiation. And things like neutrino sensors are using the same method.
