• Why Can't We Get Power From Waves?

  To learn more about this topic, start your googling with these keywords: Wave energy converter - a device for turning the mechanical energy of ocean waves into mechanical energy (flow of a substance) or electrical energy Oscillating water column - an open-bottomed chamber filled with air and water, whose wave action moves the water column up and down like a piston, forcing the air out past a turbine Attenuator - a long multisegment floating structure oriented parallel to the direction waves travel, where differing heights of waves along the length of the device flex the connections driving hydraulic pumps that can be connected to turbines Oscillating body - a floating buoy that oscillates with waves, generating electricity within the buoy or by pulling on a generator or by pumping water through a turbine Overtopping device - a reservoir filled by waves to a height higher the average nearby ocean, into which reservoir water is released, spinning a turbine Biofouling - undesirable growth of organisms like barnacles and algae on underwater surfaces Ocean wave - energy passing through water and causing it to move in a circular motion Turbine - a machine for producing continuous power in which a wheel with blades gets hit by a fast-moving flow of water, steam, gas, air, or other fluid, and spins (often connected to a magnet that spins) Induction - the production of an electric current in a wire by movement of a nearby magnetic field MinuteEarth is produced by Neptune Studios LLC https://neptunestudios.info If you like what we do, you can help us! - Become our patron: https://patreon.com/MinuteEarth   - Buy our merch: http://dftba.com/minuteearth   - Buy our book: https://minuteearth.com/books - Sign up to our newsletter: http://news.minuteearth.com   - Share with your friends and family - Leave us a comment (we read them!)

• You Are A Fish

  To learn more about this topic, start your googling with these keywords: Phylogenetic tree: a branching diagram or "tree" showing the evolutionary relationships among various biological species Cladogram: a diagram used in cladistics to show relations among organisms Monophyletic group (or clade): a group of organisms that consists of all the descendants of a common ancestor Paraphyletic group: all of the descendants of a common ancestor minus one or more monophyletic groups Similarity trap: people can name different species the same thing, only to find out they aren’t even closely related.

• The Problem With Concrete

  To learn more about this topic, start your googling with these keywords: Portland cement - the most common type of cement used worldwide, made with limestone Limestone - a hard sedimentary rock, composed mainly of calcium carbonate (which is also in shells & eggs) Cement - a powder used in construction that’s made by grinding clinker with other minerals and mixing with water to form a paste that sticks to sand, gravel or crushed stone to make concrete Concrete - a building material made by mixing cement with water to form a paste that gains body through fillers like sand and gravel Clinker - an intermediate marble-sized product in cement production created by sintering limestone with clay and other things Sinter - to turn a powdery solid into a single mass by heating it without liquefaction Mortar - another building material (used to adhere bricks or stones together) made by mixing cement with water and sand Calcination - the process of heating a substance to a high temperature, but below its melting point, so it thermally decomposes (like limestone into lime & CO2) Process emissions - the name for the CO2 that comes from limestone when it thermally decomposes MinuteEarth is produced by Neptune Studios LLC https://neptunestudios.info If you like what we do, you can help us! - Become our patron: https://patreon.com/MinuteEarth   - Buy our merch: http://dftba.com/minuteearth   - Buy our book: https://minuteearth.com/books - Sign up to our newsletter: http://news.minuteearth.com   - Share with your friends and family - Leave us a comment (we read them!)

• Why Earthquakes Are So Hard To Predict

  To learn more about this topic, start your googling with these keywords: Earthquake: A violent shaking of the earth, usually due to movements of tectonic plates under the earth’s crust. Seismometer: An instrument that detects changes in the up-down motion of the earth. Seismic body waves: Higher frequency waves released by earthquakes that can move through solid rock. Seismic surface waves: Lower frequency waves released by earthquakes that move along the ground and cause most damage. Earthquake Early Warning System: A network of strategically placed seismometers that trigger emergency warning systems in particular areas when they detect large seismic body waves. Evacuation Clearance Time: The time needed to evacuate a particular population to safety. Earthquake Precursor: An anomalous event that gives an effective warning of an impending earthquake. Transform Faults: Faults where two tectonic plates slide past each other.
