Balloon solar power collectors, illustration. Balloons floating above the clouds collecting solar energy to produce electricity continuously. During the day, the sensors produce and transmit electricity. At night, hydrogen fuel cells takes over. They are an environmentally-friendly source of energy, as they release no toxic waste products and do not rely on a limited resource for fuel. | |
