Natives ate each other took slaves and scalped people . Try again . They were savages . <| sep |> Generally , how the other game handles it , is that a single solar panel , while generally slightly less expensive than a reactorgenerator , takes up about 16 times the space and generates about 3 % the output of what a t 1 generator would produce 30 kw vs a t 1 generator ' s 1000 kw . Thus , the size requirement vs power generated is the balancing factor , not resource cost . Basically , this implementation in Empyrion would mean solar panels would be useful for lower power applications such as keeping lights , refrigerators , doors , and maybe even turrets online and operating , but would be ridiculously inadequate to power thrusters or assemblers , unless you had a gigantic solar array charging a battery all day , which then might give you 10 minutes of flight before needing to recharge .
