INTRO
Hydro turbine for use in dams; hydro works off the IRL equation P=phrgk; watts = density (always 1000 m3 for water) x height (the height the water is dropping from) x flow (a variable based off speed of river) x 9.8 m/s2 (gravity) x efficiency (better designed turbines make this number higher but never greater than 1)
Note that for the sake of our designs we will consider P=phrg to be the theoretical maximum output due to the way we will be determining efficiency.
DETAILS
I.Hydropower plants consist of the following blocks A,Hydropower control block B.Turbine chamber block C.Generator block D.Reinforced concrete blocks E.Pipe blocks [any metal]
II.When you place the turbine it scans a 100x100x100 area for 7 things: other hydroturbines, air, water, generator blocks, turbine chamber blocks, pipe blocks and reinforced concrete. It scans for air in front of it, water behind it and concrete, generators, pipes and turbine chambers to its sides. It searches the entirety of the area for other hydroturbines. A.The 100x100x100 scan is not centered on the turbine. The turbine will actually be situated at the bottom middle of the scanned cube. B.If the hydroturbine detects a nearby hydroturbine, it will not place. This is to prevent people from stacking dams with excessive turbines. C.The hydroturbine HAS to detect at least 5000 blocks of water behind it and 2500 blocks of air in front of it to work. Each 5000/2500 after that adds 1 to the height. Note that the water CANNOT be moving water. We may also want to consider making the water to air ratio another number, 3-4 water to air even, as dams do not work by discharging their entire reservoir at once. D.Additionally, the hydroturbine has to detect 99 reinforced concrete blocks for each 5000 blocks of air and water to work. E.The block also scans for the biome type its in to determine the flow rate (we can tweak these numbers if they are too low/too high) 1.River biome = flow of 10 2.Mountain biome = flow of 5 3.Extreme mountain biome = flow of 8 4.Snowy mountain/extreme mountains add 2 more to flow F.Finally, the block scans for the appropriate number of turbine chambers blocks, pipe blocks and generator block(s) of an appropriate capacity. 1.Players can use as many turbine chamber blocks and generator blocks as they desire but the plant will only generate as much as the equation allows with two exceptions a.For each turbine block the player must have at least 5 pipes of no metal in particular b.While overcapacity determines efficiency undercapacity CANNOT be permitted; the plants generator/turbines must be able to handle the dams theoretical maximum output -Example: The dam has a capacity of 500 kw, so the final check it runs is to make sure there is at least 1 turbine block and generator block both in the in the 101-500 kw range. -Example: The dam has a capacity of 20 mw, so the final check it runs is to make sure there are at least 10 turbine blocks and 10 generator blocks in the 2 mw range. G.If the minimum requirements are not met the turbine will not place or will not output power. If the latter the player will have to break it and place it again under appropriate conditions. H.The efficiency should be determined by the turbine overcapacity 1.% of unused turbine capacity determines efficiency; determined by (damns maximum theoretical capacity in watts)/(number of watts turbine(s) is rated for)= overcapacity % III.The turbine spawns a block of running water in front of it (not important; merely aesthetic) IV.Reinforced concrete blocks will be a special block that the player will need sand, gravel, quicklime, rebar and water to make. Quicklime is made by baking limestone in a kiln. A.When reinforced concrete blocks are broken they drop nothing (configurable; it prevents people from recycling concrete) B.Reinforced concrete blocks should be able to withstand nukes, and take an incredibly long time to break by other means.
ALTERNATE CONFIG OPTIONS
I.ULTRA HARDCORE E-PEEN CHALLANGE MODE: The reinforced concrete blocks scan 2 sides and their bottoms when placed. If they dont detect stone or bedrock to the sides and bedrock or reinforced concrete under them they do not place. This will force players to build concrete from the bedrock level up, much like how real dams are built. Also, considering a well built dam will produce MEGAWATTS of electricity, this may just be appropriate. [optional; not integral to mod] II.ULTRA HARDCORE UNEMPLOYED CHALLANGE MODE: The reinforced concrete block is split into 3 blocks: concrete mix, wet concrete, and reinforced concrete. Concrete mix blocks becomes wet concrete blocks when water is poured on top of them. Several minecraft days later the wet concrete blocks turns into reinforced concrete blocks. Concrete mix blocks, when placed, scan below them, and cannot be placed unless you put them on top of bedrock or reinforced concrete blocks. This simulates the process of actually building a legit concrete structure. You can't just pour it all at once due to the fact that if you did, it would crack and get fucked up while it was drying. [optional; not integral to mod]
-EXAMPLE NARRATIVE
-After some exploring the player stumbles upon a large lake situated atop a hill in an extreme mountains biome. The lake must hold around 15k blocks of water judging by its size; which makes it perfect for a hydroturbine dam. To prepare for the dam the player first gathers all the supplies to make the small hydroturbine and all the concrete necessary to hold back and channel the water. After the turbine and 297 reinforced concrete blocks are built the player then begins work on the dam itself. They start by chipping away it the area in front of the lake to create a channel for the output of the water that will soon flow through the hydroturbine. Once the channel is composed of at least 7500k blocks of air the player begins constructing the reinforced concrete wall that will hold everything in place. They build a wall seperating the empty channel from the lake and situate a small room at the base of the wall. Now that everything is in place and adjusted the player places the 26-100 kw Turbine chamber block and the 26-100 kw Generator block. Finally, the hydroturbine control block is placed and scans the biome and all the blocks around it. It detects 15k blocks of water behind it and sufficient air in front of it; it also detects the concrete to its sides. It performs the calculatios to determine the total power capacity, and then detects an appropriate amount of Turbine Chamber and generator blocks. Secured and with enough potential energy in the form of trapped water, the turbine starts its work using the following equation.
1000 m3 [the waters density; static] x 3 [the "head" or "height"; determined by volume of nearby water and air](there are 5k water blocks per "height" and this dam holds 15k) x 8 [the flow rate; determined by biome] x 9.8 m/s2 [gravity; static] x .47 [the turbines efficiency; determined by overcapacity{(capacity of generator in watts)/(portion of generators capacity being used in watts}[1000 m3 x 3 x 8 x 9.8 m/s2])= X/2] = 54,096 watts or about 54 kw.
So for their work the player is rewarded with a generous 54 kw hydroturbine. As long as the concrete and turbine remain intact the turbine will produce this continuously.
Obviously, the lake in the example was actually rather small, but the example illustrates that even small bodies of water can produce enormous amounts of electricity if damned and channeled correctly. This example also did not incorporate either of the ULTRA HARDCORE MY FAMILY LEFT ME AND IM SO ALONE challanges, else it would have taken much, much more time and resources.
