Summarize the following:
You can build as large a Tesla coil as your budget allows; however, the lightning-bolt-like sparks Tesla coils generate heat and expand the air around them (in essence, creating thunder). Their electric fields can also play havoc with electronic devices, so you'll probably want to build and run your Tesla coil in an out-of-the-way place, such as a garage or other workshop. You will also want to consider whether it makes more sense to build a Tesla coil from a kit, or gather materials from scratch. Both have advantages and disadvantages in the areas of cost, building time, resources for help, and reliability.  To figure how large a spark gap you can accommodate, or how much power you need to make it work, divide the length of the spark gap in inches by 1.7 and square it to determine the input power in watts. (Conversely, to find the spark gap length, multiply the square root of the power in watts by 1.7.) A Tesla coil that creates a spark gap of 60 inches (150 cm) (1.5 meters) would require 1,246 watts. (A Tesla coil using a 1-kilowatt power source would generate a spark gap of almost 54 inches, or 1.37 meters.) Designing and building a Tesla coil requires understanding certain scientific terms and units of measure. You’ll need to understand their purpose and function to properly make a Tesla coil. Here are some of the terms you'll need to know:  Capacitance is the ability to hold an electric charge or the amount of electric charge stored for a given voltage. (A device designed to hold an electric charge is called a capacitor.) The unit of measure for capacitance is the farad (abbreviated "F"). A farad is defined as 1 ampere-second (or coulomb) per volt. Commonly, capacitance is measured in smaller units, such as the microfarad (abbreviated "uF"), a millionth of a farad, or the picofarad (abbreviated pF and sometimes read as "puff"), a trillionth of a farad. Inductance, or self-inductance, is how much voltage an electric circuit carries per the amount of current in the circuit. (High-tension power lines, which carry a high voltage but a low current, have high inductance.) The unit of measure for inductance is the henry (abbreviated "H"). A henry is defined as 1 volt-second per ampere of current. Commonly, inductance is measured in smaller units, such as the millihenry (abbreviated "mH"), a thousandth of a henry, or the microhenry (abbreviated "uH"), a millionth of a henry. Resonant frequency, or resonance frequency, is the frequency at which the resistance to transfer of energy is at a minimum. (For a Tesla coil, this is optimum operating point for transferring electrical energy between the primary and secondary coils.) The unit of measure for the resonant frequency is the hertz (abbreviated "Hz"), defined as 1 cycle per second. More commonly, the resonant frequency is measured in kilohertz (abbreviated "kHz"), with a kilohertz being equal to 1000 hertz. You'll need a power supply transformer, a high-capacitance primary capacitor, a spark gap assembly, a low-inductance primary inductor coil, a high-inductance secondary inductor coil, a low-capacitance secondary capacitor and something to suppress, or choke, the high-frequency noise pulses created when the Tesla coil operates. For more information on the parts, see the next section, "Making a Tesla Coil." Your power source/transformer feeds power through the chokes to the primary, or tank circuit, which connects the primary capacitor, primary inductor coil and spark gap assembly. The primary inductor coil is placed adjacent to, but not wired to, the inductor coil of the secondary circuit, which is connected to the secondary capacitor. Once the secondary capacitor has built up sufficient electric charge, streamers of electricity (lightning bolts) discharge from it.

summary: Consider the size, placement, and power requirements of the Tesla coil before you build it. Learn the terminology. Gather the parts you'll need.

Add a swirl of whipped cream on top of each float, then top it off with a maraschino cherry. Serve the root beer floats with straws and long, slender spoons.

summary: Garnish the root beer floats, if desired, then serve them immediately.

If you're thinking about mining Bitcoin with your own hardware, you need to understand exactly how much of an investment you're going to make and how long it will likely be before you turn a profit. Online mining calculators can help you determine if it's really worth it for you to invest in your own rig.  Bitcoin is mined by networks of computers that solve difficult numeric problems to verify Bitcoin blocks of transactions. A block of transactions is made up of a reward subsidy and transaction fees. As of 2020 the block reward subsidy is 12.5 bitcoin, but the amount halves every four years with the amount scheduled to halve to 6.25 bitcoin around the 12th of May 2020. To be competitive as a miner, you will either need an ASIC (Application-Specific Integrated Circuit) unit connected to a computer or several GPUs (Graphics Processing Units) which would be better suited to mining alternative crypto currencies which could be traded for bitcoins. Go to https://www.cryptocompare.com/mining/calculator/ to get an idea of how much you would have to spend in hardware and electricity costs before you turned a profit mining Bitcoin. Keep in mind that for most individual miners, the reality is that they will spend thousands before they mine enough Bitcoin to put them over the top. If you're set on trying to mine Bitcoin despite the cost, you'll need an ASIC miner and a power supply to run it, as well as several GPUs. ASIC miners vary in price depending on their power and efficiency, but you can expect to spend between $1500 and $2000. Once you buy your hardware, you need to be able to set it up. If you don't know your way around circuit boards and computer hardware, this might not be the best hobby for you. A mining pool, such as BitMinter, CK Pool, or Slush Pool, allows you to pool your mining resources with other miners to increase your power and efficiency. Without a mining pool, you would likely mine for years before you managed to get any Bitcoin at all. When you register with a mining pool, you'll receive configuration settings you can use to add your mining rig to the pool as a worker. Your mining rig will start working as soon as you save these settings in your rig. You can control electricity costs by only running your mining rig a few hours a day. However, you're not likely to mine very much Bitcoin this way. Even in a pool, you're only going to get Bitcoin that your rig actually played a part in mining. Because mining rigs generate a lot of heat, keeping it in a basement or garage, where it may be naturally cooler, can be a good option. Not everybody has thousands of dollars to invest in a mining rig, or the tech savvy to keep it up and running –that's where cloud mining comes in. Cloud mining companies own massive server farms of mining rigs and offer contracts that essentially allow you to lease the power of their miner farms for a limited period of time.  There are a lot of cloud-mining scams out there. Go to https://www.cryptocompare.com/mining/#/ to research the company's reputation before you buy a contract. Smaller contracts (typically around $100) may never mine enough Bitcoin to turn a profit. Even larger contracts (several thousand dollars) may take years to mine enough Bitcoin for you to break even.
summary: Calculate mining profitability with an online mining calculator. Buy your mining hardware. Join a mining pool. Run your mining rig constantly to maximize profit. Pick a cloud mining contract package if you don't want to build your own rig.
