So if we think of the windy areas of China, huge gusts could come through, and unlike most power stations that don’t know what to do with 100 megawatts that show up at one or two in the morning, the system could place all that excess energy into greenhouses and growing facilities, protected from the gale but using the wind to grow plants to make the vegetables. These plants could grow on long racks in meter-high stacks, using only the spectral frequencies of the light that each vegetable needs.
A battery is just something that converts chemical energy into electrical energy. Here electrical energy is converted into chemical energy. Earth as a battery, plants as a capacitor. Instead of metal batteries that are expensive and toxic, how about food as a battery, storing energy for our beneficial present and future use?
Now that’s an idea.
1. The photosynthetic act claims six times the amount of energy in terawatts that humans currently use. Plant life is greedy with its energy needs, greedier than humans are, and yet because of the nature of the energy source for vegetation—the sun—there is no reason to complain. Not only that, the photosynthetic process usefully absorbs energy and stores it, often usefully for our potential need, either as food or as fuel.
2. In traditional soil farming, the key limiting factor is the active transportation of nutrients to the roots. Freshwater aquatic systems are ideal media for vegetation. Salt-water agriculture is also a possibility: Tomatoes are being grown on salinated farmland in Saudi Arabia, for example.
