What a nice idea, But, it seems not suitable for windy places where wind turbines may be used. It also seems not very safe in earthquake regions. I presume that wear is the aspect preventing it form being implemented.
Just imaging thousands of autonomous drones swarming the skies delivering letters, parcels and bringing back daly diary delivery... In Rwanda there is the flyzipline project successful. Wonder how this will affect general aviation...
“This planet has - or rather had - a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movement of small green pieces of paper, which was odd because on the whole it wasn't the small green pieces of paper that were unhappy.” Douglas Adams
Hold music... I once was forced to listen to noisy low quality overmodulated hold music for an extended period of time. This made me wish for three meteorites to annihilate the company, the call center, and the guy who composed the hold music. The longer the expected holding times are, the higher quality and more varied the hold music should be.
I never understood why fossile fuel is still so widely used. From a chemist's point of view oil is such a versatile ressource. For me burning fossile fuel is simply like heating a house by burning lego bricks. (Which is possible, as ABS-plastic the lego bricks ar made from is not self-extinguishing.) It is common knowledge that fossile fuel is limited an one day we will have to develop methods to replace it by renewable ressources. Why not starting now to massively develop alternative and renewable energy sources, as we will have to do it anyway in near future?
