small suggestion thou, the ice and water cells seem under powered.
true, you sacrifice protection over efficiency. but its an bit... to les
i suggest ice : -150
water : -100
lava (here we go) : +1000 heat
the reasoning behind the suggestions:
the ice, wel. normal ice blocks cool for 300 heat each. concidering an normal CASUC reactor is good, but when an system error apears, there is an massive crater.
sacrificing 50% effective cooling for 100% protection (+ some EU) seems fair to me
the water, normal buckets cool for 200 each, you sacrifice 50% efficiency for protection, any more seems under powered since this also consumes the cells themself if i am not mistaking (consumes tin) which is in fact. equal to iron. thus seems verry expensive, and not an good option for serious reactors (only verry cheap ones)
so, water. seems to me verry verry expensive coolant, (i might suggest an refund of the tin cells to balance it, if thats posible ofc) if it isnt, i suggest the total coolant should be alot higher then 200 ea, (i suggest 700-1000 ea, whatever suits you best)
the lava, wel wel. expensive isnt it? +50 heat for 1 lava.... i could just drop in an bucket of lava and get +2000 WHOPA!
i suggest making it +1000, also same story as the water cells. consumes tin. fucks up balance, i might say, make it more efficient then normal buckets. since it is more expensive on lava consumption and resource consumption.
over all, the efficiency of each cell should be arround 50% of the normal single use coolants - heaters. this seems an fair price for total protection..
