====== Spaceship power ======
The following values/power point for different sizes are calculated from the weapon damages with the base weapons being 25% efficient and one shot/20 seconds and the improved versions as 50% efficient to get the extra rof with same energy.

====== Power Cell energy ======
calculatrion:
<code>
TL 11: REF 10, that is 10s time the energy of corresponding TNT
TNT is 4184kJ/kg.
Thus the energy is 4184kJ/kg*10=41840kJ/kg (42mj)
That is 41840kJ/3600 seconds=11.6 kwh.
Each TL seems to be a 4x step according to the REF numbers and the blaster/laser design in pyramid 37 so:
a TL 10 one is 2.9kwh/kg and TL 9 is 0.73 kwh/kg
A C-cell at 227 grams is thus about 165 watt hours.

Rechargeable are assumed to be half that.
</code>

So rechargeable kwh:
|TL|1kg|c-cell|
|9| 0.3625|~~=cell(col()-1,row())*0.227~~|
|10|~~=cell(col(),row()-1)*4~~|~~=cell(col()-1,row())*0.227~~|
|11|~~=cell(col(),row()-1)*4~~|~~=cell(col()-1,row())*0.227~~|
|12|~~=cell(col(),row()-1)*4~~|~~=cell(col()-1,row())*0.227~~|
