Plasma, The Forth State of Matter By Andrew Nyholm
How is Plasma Created and Why? • Plasma is created at a very high temperature when atoms in gas molecules decompose into positively charged ions and negatively charged neutrons. • Although the molecules have decomposed, the magnetic fields of the ions and neutrons keep them associated allowing the particles to move very quickly.
Where is Plasma Found? • Plasma in the universe is said to hold up to 95%-99% of all matter. • Plasma on Earth is commonly found in fluorescent lamps and as lightning. • Things such as stars, solar wind, and many other interstellar objects are made from plasma.
What are the Properties of Plasma • Most terrestrial plasma or plasma on Earth, acts like gas and the definition of plasma is sometimes that of ionized gases. • Plasma is most like a gas in properties, for its molecules are not in constant contact. However not all properties are the same, for example: the molecules move in what scientists call collective motion. • This means that the molecules move as a whole, not randomly, but can also contain lumps of particles
Where do these Come from? • Plasma gets these properties from its ion attraction and repulsion due to magnetism from the ions (with a positive field) and neutrons (with a negative field) they contain. An important note about ionized gases is that only a very small fraction of the gas needs to be ionized to show properties of plasma.
Magnetohydrodynamics • Magnetohydrodynamics (MHD) is a theory that says that plasma should be treated as an electrically conductive liquid. • This theory has been used in success to explain solar flares, solar wind, and star formation along with other astrological events. • Scientists have compared the Earth’s molten, swirling, magnetic-field-creating core to an MHD liquid due to its creation of the Earth’s magnetic field.
I have been fascinated by plasma ever since I first heard of it. I have been thinking about how to use plasma to help engineer the future since I was young and have thought of some unique ideas.
Lightning Power Conversion Tank • Lightning (a form of plasma) is a seemingly unusable resource but I have thought about it and have a solution. • The problem with lightning is that the electricity is static, not current, which makes it unusable to tap directly. • I have thought of a way to indirectly tap this power source and use the power not as electricity but as a chemical reaction in one of the most famous molecules ever, good old H2O.
How would I do this? • First we must understand some basic properties of Oxygen and Hydrogen. • Hydrogen, when burnt in contact to Oxygen, creates heat (energy) and also H2O (water) by bonding together with the oxygen. • Now one way to separate the bonds of H2O is to introduce electricity, like from lightning. • One problem with this process is that there would be a large amount of highly flammable Hydrogen in a Oxygen rich environment with lightning, which can set it off, all around.
Plasma as a Weapon • Plasma cannot be contained in any substance known to man but it can be held by a magnetic field. • This opens up the option of having weapons of war that contain plasma in an electric-magnetic field and then release the field as a permanent magnet is shot at the target with the plasma following the magnetic field created by the magnet.
