Sailing yacht with circle keel
Sailboats with hydrofoils already exist. They are used in catamarans. An article about airplanes with a circular wing inspired me to apply this design to a sailing ship.
A circular hydrofoil accommodates a moving counterweight. The weight must be able to be moved back and forth in such a way that even a sailing ship that has been turned upside down could straighten up again.
Nautilus Project
The Nautilus is a squid with a spiral-shaped shell. Fossils of the nautilus have been dated back 420 million years. For a time they were thought to be extinct.
However, in the period that more sea research was done, it turned out that the Nautilus still live in a number of families. This makes it one of the longest living animals that has changed little since its origin. Their success is partly due to their shells. The spiral growth makes the shell strong. That growth was part of what inspired me to This Nautilus Project. The other part of the inspiration came from a marine research vessel “RP FLIP” which was built back in 1962 and could be tilted vertically in the water to conduct sound research.
The idea, for the Nautilus Project, has been in my head for years. Thanks to the developments
Energy and heat from an artificial geyser
With an artificial geyser I mean something like the geysers known from Yellowstone Park in North America but homemade.
A geyser arises because there is a cavity under the ground with a connection to the surface of the earth. This cavity fills with water. The water is heated above the boiling point. The water will evaporate at some point. Water evaporates where the heat heats it. Then water vapor bubbles form in the water. The specific gravity of water vapor is much lower than that of water. This raises the bell. As the bubble rises, it passes through lower temperature water and heats that water and condenses the water vapor. Only when all the water has reached a sufficiently high temperature will the water vapor bubbles reach the surface. Then the geyser starts spouting. The water vapor finds its way up and immediately takes an amount of water with it and then we see the boiling
Geothermal heat
Geothermal energy can be used to generate energy and to heat buildings. The heat of the earth comes from the core of the earth. The way the heat is generated in the core is beyond the scope of this text. The deeper you drill into the earth's crust, the higher the temperature. The temperature at a depth of 1 meter is influenced by the average air temperature. The difference between winter and summer is only a few degrees. In the Netherlands, the temperature at a depth of 1 meter is about 10 °C. For every 10 meters deeper,
Thinking out loud
It was Monday, June 29, 2020. In a link from the ANS bank https://www.voordewereldvanmorgen.nl/duurzame-blogs/recordbroken-zonnepanelen-behalen-hoogste-rendement- Never came in an article https: // edition. cnn.com/2020/02/05/us/solar-panels-work-at-night-scn-trnd/index.html that was about a new kind of solar panel.
This panel works in the infrared region
A green desert
Only mineral-poor water is needed to grow a desert. As strange as it may sound, there is enough nutrition and there are enough seeds available. To make this, often due to heat, dry soil green again, only water is needed. But where do you get the water from? Seawater contains too many minerals and there are only a few plants that live on land and use seawater. All other plants need mineral-poor water, which we know as rainwater or
