Which alternative is INCORRECT concerning the following paragraph?

Recently, engineers have found new and easier ways to get water in dry places. It is simple – they have made machines that take water from the air. There were already a few machines like this, but they didn't make enough water for a whole village. The new designs are better because they can make many more liters of water every day, they are cheap, and they use much less energy.
