Space Exploration presents many new tools and challenges for creating power across your local interstellar cluster.

Stand-alone generators require no water, making them suitable for arid environments. They're also simple to setup and use, and compact. The downside is that they have lower efficiency.
|Generator||Efficiency||Electricity Generated (MW)||Fuel (MW)|
|Burner Turbine Generator||85%||2.0||2.35|
|Fluid Isothermic Generator||75%||2.0||2.66|
Heat exchangers consume water and fuel and output steam at precise temperatures. Space Exploration adds the High-Temperature Heat Exchanger, which lives up to its name by consuming more heat and outputting higher temperature steam.
Boilers are fueled by inserters, but Heat Exchangers and High-Temperature Heat Exchangers are fueled by nuclear reactors, antimatter reactors, energy beam receivers, or heat pipes connected to any of the above.
|Entity||Water (units/sec)||Fuel (MW)||Steam (units/sec)||Temperature|
|Heat Exchanger||103||10||103||500 C|
|High-Temperature Heat Exchanger||562||560||562||5,000 C|
Turbines consume steam and output electricity. Space Exploration adds the Condenser Turbine and the High-Temperature Turbine Generator.
The Condenser Turbine is similar in function to the Steam Turbine. However, rather than consuming 500 C at 60 steam / second, it instead consumes 80 steam / second while outputting the same amount of power. In exchange, it will return 99% of the original water. This is essential for arid environments. Unlike the Steam Turbine, which operates at a lower rate if insufficient steam is delivered, Condenser Turbines will pulse on and off as sufficient steam for one operation is collected. Additionally, please note that Condenser Turbines can handle steam up to 1,000 C while the Steam Turbine is limited to 500 C. The below table displays operation using 500 C steam as this is the most common usage (produced by Heat Exchangers and High-Temperature Turbine Generators).
The High-Temperature Turbine Generator consumes 5,000 C steam and outputs 1 GW of power. Additionally, it also returns condensed water and 500 C steam, which can be further processed into either a Steam Turbine or a Condenser Turbine. Note that the High-Temperature Turbine Generator, similarly to the Condenser Turbine, loses 1% of input fluid, returning 78% water and 21% steam. This means that, for example, a fluid cycle that consists of a High-Temperature Turbine Generator working at full capacity, chained with three Condenser Turbines required to process the low-temperature steam, would lose 1000*0.01 = 10 units/s of water on the High-Temperature Turbine plus 210*0.01 = 2.1 units/s on the Condenser Turbines, so a full tank of water should last for about 25000/12.1/60 = 34.44 minutes.
|Entity||Steam (units/sec)||Steam Temperature||Electricity Generated (kW)||Water Returned (units/sec)||Additional Notes|
|Steam Engine||30||165 C||900||0|
|Steam Turbine||60||500 C||5,800||0|
|Condenser Turbine||80||500 C||5,800||79.2|
|High-Temperature Turbine Generator||1,000||5,000 C||1,000,000||780||Also returns 210/sec 500 C Steam|
Space Exploration also provides three upgraded versions of solar panels. Although slightly larger, they can be walked on and generate significantly more power.
|Entity||Electricity Generated (kW)||Tech Level|
|Flat Solar Panel||400||Rocket Science|
|Flat Solar Panel Mk 2||800||Energy Science 1|
|Flat Solar Panel Mk 3||1600||Deep Space Science 1|
Solar panels placed in orbit or on spaceships will run at half efficiency but will always have access to sunlight. A common strategy is to place flat solar panels around a star's orbit and then beam the power to where it is needed. Representative solar values are presented below.
|Location||Solar Efficiency||Beam Transmission Efficiency|
|Asteroid Belt at Mid-System||172%||63.86%|
|Asteroid Belt at Edge of System||20%||51.62%|
Production / (Consumption) Table
For every 1gw of heat available from, say, an antimatter reactor setup, you will want 2 high-temperature heat exchanges, 1 high temperature turbine generator and 3 condenser turbines.
