The sea is a forgotten energy source.



Tidal waves and ocean currents are forgotten energy sources. 


Tidal waves offer a potential energy source in many places on Earth. The tidal waves can travel through the dams that are equipped with turbines. Or water can travel over the water mills, there is the generator connected. The system can use the dams that can fall if some big freighter must travel through. 

The tidal dams that can let the tidal water travel through those turbine channels can harness energy from that water flow. And in the case of storms, the dam can close those channels if the water level rises too high. The water power can be also in cases like the Ijisselmer in the Netherlands where the water must travel through the dam anyway. The dam can be equipped with turbines and generators. 

The hydro plants can also be more effective. If the drainage channels in existing hydro plants are equipped with turbogenerators. Those channels can also produce electricity. The system can drive electricity to the batteries. 

Another thing that can used for energy production is the ocean currents. The ocean currents are water masses that travel under the ocean surface. The normal wind generators that are put in underwater positions can harness energy from those underwater water flows. And also the smaller scale water flows can benefit electric production. 

The gravity systems can also be effective. The gravity system can be the gravity battery, where the weight moves up and down between the bottom and the surface. 

In some versions, there could be gravity plants in the ocean. The system can use pontoons that can filled with water. The pontoon is between the bottom and the surface. First, the pontoon is filled with water. And when it dives. It rotates the generator. At the bottom of the sea, the system blows pressurized air into the pontoon. And then it starts to rise from the bottom of the sea. That thing can also rotate generators. 

In some simple versions, the system puts sand in the box in the pontoon. That sand makes the pontoon sink. And then that thing puts the generator rotate. When the pontoon is in the bottom of the sea. That sand will drop out and the pontoon starts to rise. The capillary hover that archeologists use when they suck samples from the bottom can be used to bring the sand up again. 

That capillary tube can also bring water through the turbogenerator. That is used to make electricity from water by using electrolysis. The normal offshore oil rigs can use this system to produce hydrogen. Hydrogen can be used as fuel in regular power plants. 

The wave energy itself is the potential energy source. The waves are moving the cylinder back and forth. There is a stable structure that acts as a stator in that system. And when the shell is moving. The system called the "duck" acts as a generator. This is one version of how to benefit the waves and ocean energy resources.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft.  Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things.  In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion.  If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful.  Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down.  The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts.  The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
