drbubb Posted August 6, 2007 Report Share Posted August 6, 2007 Flying Electricity Generator Is this a viable way forward? =================== Intriguing video footage of a proto-type: Prototype of Flying Electrical Generator A prototype of the Flying Electrical Generator is tested, first in powered flight mode, then in electricity generating mode. The rotors harnessing the wind power have a diameter of 4.6 metres (15 feet) Link to comment Share on other sites More sharing options...
silverharp Posted August 6, 2007 Report Share Posted August 6, 2007 http://www.wired.com/science/discoveries/news/2006/10/71908 how about this, a merry go round generator. re the flying generator, what are the advantages Link to comment Share on other sites More sharing options...
malco Posted August 6, 2007 Report Share Posted August 6, 2007 Answer: nope. Always the same problem with any wind turbine and that is the tenuous density of energy available from wind necessitating gigantic machines. Germany is put forward as a great example for wind but in fact proves that such turbines are a dead end. They have installed a wonder of the world of wind turbines along their Baltic Coast and elsewhere, yet while wind turbines now amount to around 15% of installed capacity they generate only 5% of electricity in Germany. Their purpose is political, to create the impression that something is being done when in fact it is not. We are not yet at the desperate stage when we are scrabbling to keep the grid going. So we can afford a few indulgences. The autogyro depicted is a toy and no more. Link to comment Share on other sites More sharing options...

Even if wind turbines (for instance) can be shown to have a positive EROEI (something that begins to look more than a little dubious when taking into account the entire energy cost footprint of the technology, there still remains the problem of speed of supply. These renewable energy technologies simply will not deliver the sheer quantity of energy in any given unit of time required to run even a shadow of our current economies given our global population size The real elephant in the room: We need less people..... A LOT LESS people. In the absence of such a reduction in the human population, everything else is fantasy Steve Link to comment Share on other sites More sharing options...
