The additional revenue might initially come from selling small electricity surpluses to local farmers to recharge their mobile phones (thereby allowing them to work out the optimal prices for their crops), or to help them irrigate farmland using small electric pumps.
额外收入最初或许来自将很少的多余电量出售给当地农民给手机充电（这样他们就能将农作物卖到最优的价格），或者帮他们用小型电泵灌溉农田。
