The other day I was riding my bike along the scenic beachfront cycleway near Burn’s Beach just north of Perth when I was amazed to see a maintenance worker blowing the sand off the pathway with a leaf blower. He was taking about ten minutes to clear a few meters of pathway, so it would have been quicker to use a hard-bristled yard broom and sweep it off.. It certainly would have been more pleasant for the passers-by who had to put up with the noise and smoke.I think the maintenance guy probably would have preferred to use a broom too,because he could have had the arms swinging and got a bit of a workout instead of having to brandish a belching noisy pollutant generator.
Solar Powered Sanctuaries
A paper by Michael McGuigan proposes using ring-shaped scalable solar power plants. his idea of erecting a ring of solar plants that is then effectively a barrier protecting a large area of land that can can populated by endangered species is feasible.The ring formation would probably be less damaging on the environment that a large grid array considering we would need to build thousands of such plants to power the planet. It’s also more efficient to build closer to the end-user than in the middle of the desert
