SUN + TECHNOLOGY = POWERED EXPEDITION
The Sun is in the sky everyday and is sending energy from the distance of 150 million km (93 million miles).
The Earth receives the energy from the Sun and if there is no-clouds one square meter receives one kilowatt of energy. Even if there is overcast sky the area of small swimming pool would receive enough energy to power an average household. That would happen during six hours of such weather condition. We just need to harvest that power. Solar energy is clean energy that means it has no impact on the nature versus energy generated from burning coal, oil or gas (greenhouse gas emission).
We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature’s inexhaustible sources of energy — sun, wind and tide. … I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.
