Hi everyone ：P
Do you ever check this Amazing Space Sim Game? Name Alliance Space Guard(ASG) .
Better take a look, I thing It's a pleasure to communicate with that developers. 0w0
it give really detial for how linear fusion engine works.

As an example, I take a space power station with a nuclear reactor (and also something like a load like an ion engine or a microwave transmitter) - with good cooling, your radiators will stop accumulating temperature at ~ 1100K
I more likely to put that temperature higher, and just use enough radiators Area to make a good Power/Mass Ratio.

exactly where did you get this number from?
according to this document, iso will not be higher than 211s
that numbuer just some theoretically Max，like that LOX/ LH 2 Rocket Combustion in chemical equilibrium can get 510s + at max 100% Eff
Sorry I dont make that clear
pic from :https://zhuanlan.zhihu.com/p/67562119
I just look again, it a Solid CO Mix LOX, thing might get different
-
I Just think up a new thing
We already have a multi fuel-functional chemical engine.
So why not add a new fuel mix-- CO/O2 rockets?
look for that isp about 250-280s
if it can add to NTR after burn mode that will way more better.

Will that Resistance thruster coming soon？ I hope that at 300sci level node (same with First power generator）

Alright, I think I fixed it
As you can see it now only produces 2.16 MW, equal to the maximum electric power of the generator which is configured at 1% (weighting only 0.179 t).
Wow that a really Quickly Fix, how can u do that ：P
So quick that For Now we just made some free time to watch Space X Lunch there New Firewor..... Eh... The New test rocket that will gona Booooom （in plan）soon.

Long time not see
First I want to say that New UI of Propellant selection are really great to use, I really appreciate it
And that TEG come with Variable installed capacity also very useful for build light weight craft. But still look like has some minor bug like, when u reduce that capacity of generator to 20%， that reactor still been require as 100% power, and that rest of Heat Power beem turn in to Waste heat , that make those generator are not beem reduce capacity but efficiency as -80%,
For example：Heat to MJ power efficiency with 20% capacity of TEG：
A Reactor that with Max 100MW HeatPower, TEG current efficiency in 50%,capacity 20%
ideal： H×20% ， 0.2H × 50% Reactor run in 20MW to support 20% capacitygen to get 10MW power. Waste heat 10MW
current: H ×(50%×20%) Reactor run in 100MW to support 20% capacity gen to get 10MW power. Waste heat 90MW.
"H"as Reactor power level.
Result in a lot of waste for energy and Over Heat Radiator......

KSPIE 1.24.1 is now avaialable for Kerbal Space Program 1.8.1
Released on 2019-10-31
- Compiled against KSP 1.8.1
- Balance: Reduced mass and cost Magneto Inertial Fusion Engine
- Balance: Reduced drag and mass Thermal Receiver dish
- Balance: Reduced fuel storage and fuel efficiency Pebblebed reactor
- Fixed several gray (DDS) textures
- Fixed texture, time warp animation, and power warning on Magneto Inertial Fusion Engine
- Fixed Fusion Engines Filter extension
LOL I remember that Deinonychus 1-D Chem Eng was put in Fusion Engines type, some how feel that partly correct because they have operate in a similar way —— by putting two thing together to make it heat up and eject out.
-
I Remember it have Isp throttle For MIF engine , For now It been remove ? again ?

Ah right, for those engines Squad hid the old ones and the new ones are entirely new parts. So they need configs.
Temporary solutions， If you have Filter Extensions and switch to Squad tag for all part you can see that old part . that can be show that old part still here and have RF feature.
Perhaps that is another bug by Filter Extensions that cause Failure to hide old part
.(but helpful)

What I need a detailed description on how to reproduce the problem
Try use Pebblebed and other reactor like MIF in Same ship, both have link on TEG . And save/load or Warp time. that may happen again

I just ran into this problem as well (KSP 1.5.1) . In some cases the RFBR (aka Timberwind) reactor stops generating Thermal Power - Reactor Status in the Reactor Control Window shows Active (0.00%), whereas a normal working Timberwind usually shows (0.020%) when idle, producing a steady 12KW of TP. If you shut the reactor down, the decay heating kicks in and starts generating thermal power for a few days until it cools off. Unfortunately I can't reliably reproduce the issue after various tests of reloading, warping, switching vessels etc . If I can figure out a way to do so and catch it in the logs I'll update the post.
Same Problems， when you open debug— you will see " [KSPI]-managed ProvidedPowerSupplyPer SecondMiniMumRatio illegal Values." that flash very fast and push over other messages.
Is that kind of Bug?
Edit:
I running on KSP 1.4.5, Have RSS and RF，That ship have pebblebed in 1.25m, MIF Fusion Engine 2.5m，2 CANDLE as payload use（Tiny airless lander）. one TEFR 0.625m on payload. Pebblebed and TEFR Have no power and lock in Active (0.00%). No fuel consume on Power Generator . However that MIF still can use and work normal.
other Solid core NTR are normal too.

Second idear is about Chemical combustion reactor. You can think it as a close cycle rocket engine or reactor but power by chemical. When run it produce TP by combining chemical fuel and re-collection Combustion product（Like Water, CO2, etc） . Can link to TEG for cover to MJ, or link to Thermal nozzle. Core Temp Decide on combustion type, can have a cap on 3200K (Not on MHD)
If this Link to Thermal nozzle that can be a new evolution of chemical engines
！You get the engine power by Chemical combustion but Isp and propellant same as Soild NTR!
Ex：
Let burn H2 to get heat
H2+O2=H2O（recovery） + Heat（3200+K）
Recover water then heat propellant directly through heat exchanger ;
propellant+Heat(3200+K) = thrust with high Exhaust velocity
get thrust and isp same or even higher than NTR， and not lossing much propellant
ideal to handel some low △DV orbital transfer
If you like you can even burn a coal (Carbon) to power your Steam Rocket ！！
By burn some soild fuel and heat propellant directly through heat exchanger.
C + O2= CO2↑ + Heat
it also recover that carbon to some product that is easy to handle.
After some long time thinking , I re-think about what I'm going to say.
The way to improve that Chemical rocket efficiency (in weight way) is reduce oxidizer.
To do that, first we need make sure that "fuel" are way more than "oxidizer", and then we don't use oxidizer as a propellant, because it high in molar mass will reduce ISP for engine. I think that a jump out the box to thinking.
How to do that? By reuse that oxidizer again. burn fuel and oxdizer in a close system and them let Heat heat up propellant (normally fuel) by pass heat exchanger. Result high Exhaust velocity and low mass follow. Get lot thermal Power to use, and byproduct like water Steam and CO2 need storage, and electrolyze that to get back oxidizer in idle time.
Overall:
①A engine that Isp and TWR similar as solid core NTR but it a chemical! It mean no need of rad shied and Eco-friendly, and no special resources are needed.(because nuclear fuel are rare.
②Reducing the risk that fission fuels are easily owned by civilians, it might be use to trade in black market and be use to make a bomb in some secret place.
③Burning time are limited(by how many oxidizer and byproduct storage can use in one time ). So It might burn muti time rather than one burn to finish orbital transfer.
④Low in Technical, rare resoure requite.
⑤tradeoff to reduce Overall power to get mass saving.
⑥ In theory it can use any propellant ! （ rather them few combustion for chemical rocket）

We already have fuel cells in stock KSP - but RTGs are still more efficient.
Stock fuel cell are open cycle systeam, it mean it will loss mass when running. And only work for stock fuel.
both are also running on low power (16KW or lower).

Once you'll do the research, you'll notice that energy density of chemical reaction is way to small for such an idea to be feasible. Even if you could transfer energy efficiently from combustion products - what you can't do efficiently, and using Termal Power Generator wouldn't be that great
Well, I designed the main purpose of the device Not only for energy, but also recover that cryogenic fuel back to Easy to store fuel （such as water）with higher density and boiling point, save on tank mass and Volume. In this case energy is a by-product. It can be electrolyzed againg by some low and stable power supply.( Like charging a giant battery/ Regenerative Fuel Cells)
And also, even that fuel combustion energy density are low, but the power ratio for combustion should way more higher then early reactor. In futher, we can have MPD generator to deal with some high adiabatic flame temperature such as H2+F2 (8000+K).
As alway. In space Energy are cheep, but Materials are expensive.

Hello there, After some long time thinking and explosion , I have got some new ideas for Energy harvesting from Chemical Power.
First is about Oversize Fuel cell. That's very obvious，It can conversion H2+O2 to water, Power and wasteheat. And it can also use Hydrazine as fuel too.Ex：Hydrazine Fuel cells
Second idear is about Chemical combustion reactor. You can think it as a close cycle rocket engine or reactor but power by chemical. When run it produce TP by combining chemical fuel and re-collection Combustion product（Like Water, CO2, etc） . Can link to TEG for cover to MJ, or link to Thermal nozzle.

More thing i will add after research
Purpose:
Fit the gap between Solar power, Low power reactor and Capacitance，New way to Handle Chemical fuel (like burn secend stage Hydron fuel to easy storage water), Give more Fun on low tech experience.
Tech tree:
Both Unlock at High power ec system same with TEG, can be update by tech

I'm using a bit less optimistic version
Spot size = distance-to-spot * wavelength / (aperture diameter)
I wonder where the 0.61 comes from
Perhaps a more accurate formula would be
1.22 * distance-to-spot * wavelength / (aperture diameter)
Alright, Got that, I try to make a Excel witch wavelength Eff Range to help choice ideal beam type.

I've tried that, but it's still not working. I've used hyperedit to erase all the waste heat, just in case, but it makes no difference. I don't have a KSPI fission reactor on board as well, but if that was needed, why was I able to depart Kerbin and capture at Neidon? What does the error means?
Maybe you can try to use a small fission reactor (Motle salt or else) to power the Fusion reactor, than power main engine?

All right,so the
distance eff.＝Receive diameter / Spot size *100% ？

I am doing localization tutorial and for now it part for Beam power, I try to make a equations form on excel , Is this Equations I choose correct?
RT = 0.61 * D * L / RL
where:
RT = beam radius at target (m)
D = distance from laser emitter to target (m)
L = wavelength of laser beam (m, see table below)
RL = radius of laser lens or reflector (m)

Why most Reactor are lack of durability? Like Molten Salt reactor that Power start decline just in 5 hour on full power! Why their are become so weak now?

I wounder is there are a Best propulsion isp（Ve）？And best Eco Mass Ratio?
it decided by Propulsion system's thrust power and Kinetic energy change rate (△Ke/Tp)
is that number important?
