Sorry, I missed that. Let's see ... * A TL8 rechargeable E cell is $2,000 or Cr240 for 50 kWh. * A TL9 rechargeable E cell is $2,000 or Cr400 for 75 kWh. * A TL10 rechargeable E cell is $2,000 or Cr620 for 100 kWh. The most cost-effective choice is to import TL8 cells, and the weight is less than the required gas or diesel, if you use the VXii23 fuel consumption rule. However, the diesel to produce 50 kWh is $1.44 or Cr0.072. The power cells would have to last for 3,333 charge cycles to make them worthwhile, and that is ignoring the cost for power from the grid. > You need land usable for agriculture, that are not used for anything else, > like planting cash crops, personell working on it, and your agriculture > machinery will itself require fuel, you still need a processing plant, > maintaining that again requires technical know how. VXii19 has fuel alcohol stills. They need fuel to operate, but as it happens that is less than the fuel they produce, so you can see it as simply reducing the yield. 31.25 lbs. of grain or 125 lbs. of fruit per gallon of output. Will the agricultural machinery require fuel? At historical TL6, much of that was still horse-powered, so you could have animal-powered mowers and threshers to provide fuel for a few cars and trucks. Besides, power for power cells has to come from somewhere, too. > Propably you still > need a distribution network (unless you have one central gas station for > the whole colony) A Small Colonial War by Robert Frezza.

You have to increase the power output, too. Build and maintain another hydroelectric dam. Mine coal for another coal-fired power plant. Build and operate another reactor.
