Hacking a Volcano

The magma volcano isn't hard to control - there are plenty of clips and tutorials on youtube. But what about overclocking it, i.e. getting more energy than it gives? No bugs, no mods! Finish (if possible) to the end, there's a bonus below.

General View
The scheme consists of 2 chambers: the left one with the volcano, the right one with the turbines.

The idea is to melt less heat-consuming regolith (SHC, heat capacity of 0.2 DTU/g/°C) in magma. After it melts (in a 1:1 ratio), it becomes magma, with a SHC of 1 DTU/g/°C. Technically, its thermal energy, will increase 5 times by leaps and bounds.

Automation
Every 100sec. both doors open, magma pours onto the diamond tile, solidifies a pile of regolith, and falls out the lower door. After 6 seconds, the upper door closes, and after another 6 seconds, the lower door. The pile of rock turns out to be jammed by the door, which multiplies the heat transfer from it to the chamber with steam, through the diamond cells.

If the steam becomes hotter than 195°C, the upper door will stop opening, and the lower door, on the contrary, will remain open.

The regolith will be fed when the magma temperature is >1500°C (so it doesn't solidify) and provided the previous regolith have already melted.

Sensors



 * Thermosensor (at the volcano) >1500°C
 * Weight Plate <10kg
 * Buffer (to Conveyor chute) - 5 sec.
 * Timer sensor - 6 sec. - green period, 100 sec. - red
 * Buffer gate (bottom door) - 12 sec.
 * Thermosensor (under turbine) <195°C
 * Liquid pipe thermo sensor >95°C

Materials



 * Doors - wolframite.
 * Perimeter Insulated tile, Insulated liquid pipe - ceramic.
 * Tiles, Conveyors, Pressure plate, Automatics near Volcano, and Mesh tiles and Automatics near them - steel.
 * Other pipes, conveyors, wires, etc. - Copper/Gold amalgam.
 * The tiles near the bottom door are Diamond.
 * Steam - 500kg/cage.
 * Volcano and between doors - vacuum.

For maximum efficiency, the regolith was fed at t 250°C. Its temperature at the surface reaches 300°C. For it to reach the circuit at this temperature, lay the conveyor rails under the ceramic Insulated tile. You know where to get tons of ceramic, don't you?

Further Refinement
Volcanoes have very different parameters. For particularly active volcanoes, it may be necessary to increase the length of the chamber with the volcano, extending it to the left, so that the volcano does not stop. You will also need to adjust the buffer of the bottom door by increasing its opening time, so that the regolith has time to fall out into the bottom door, rather than freeze in the Mesh tile.

The efficiency of the scheme can be raised if you apply self-cooling turbines. You would need at least twice as many of them.

The circuit can also work with a Minor volcano. It may be necessary to reconfigure the buffers and to throw out 1 turbine.

The scheme can work with regolith of any temperature and even without it (to the detriment of efficiency).

Test
The simplest circuit was assembled from the door and 2 tiles. The chamber was heated (by pouring magma and then wiping it away).

2 drops of magma with temperature 1827°C=2100°K, 1840kg x2 (standard parameters), and regolith with temperature 250°C=523°K, 9200kg, (4600kg after dredging) were placed in the circuit. After melting the regolith, 8280kg of magma was obtained, with temperature 1425°C (=1698°K). Heat capacity of magma - 1, regolith - 0.2.

The efficiency was: 171,3%

In the circuit, I am melting the regolith to a temperature of 1500°C, so the efficiency will be somewhat lower. Nevertheless, this is an excellent result.

Bonus
My son came over and said, "What kind of crocodile is that"? After that, the legs and ears were added to the scheme :) We got a robo-dog. He has a muzzle, a red tongue, brain, digestive tract, and even released gastric acid (water from the turbines). He feeds through his... tail, but that's fixable. You can feed him through the Auto-sweeper from the muzzle.

Be sure to build a scheme and give it to your sweetheart for her Birthday or Valentine's Day. Maybe she will condescend to your hobby.

Update: A user named Soul-Burn on reddit suggested a more correct name for the scheme: HOT DOG.
