Renewables-2017

Dr. Gábor Szabó, President Dr. László Antos, Executive Director Hungarian Association for Innovation Dr. István Blazsek, President Dr. Ivan Budai, Director Hungarian Chemical Industry Association   Dr. Roland Feketa, President IPE – Association of Industrial, Science, Innovation and Technology Parks Dear gentlemen, 19.09.2017 Danube countries using their nearness to Black sea and its unique potential for very cheap, simple and clean energy production, they can reach fuel and electricity independency, with a help of Ukrainian outsourcing and my fresh looked innovations, while Ukraine has high professional engineers and workers and extremely low cost of labor. A small international group can promote it, and I ask you to help me in your separate country. Disclosure for experts [ (1a), (3) and (4) need some additional time for R & D. All costs are correlating each to others and corresponding here to Black sea conditions] (1) electricity b...

Arrays of Lattices of small HAWTs lifted high in the sky Author: David Judbarovski, principle inventor, engineering and engineering systems, retired engineer, Israel email: judbarovski@gmail.com , CV see in Linkedin.com (David Judbarovski) Earlier versions goes me back to about 10 years ago Numerous small HAWTs (horizontal axis wind turbines) combined in a lattice, the said lattices are jointed each to another as a chain. Such device transforms wind kinetic energy in electricity. A total HAWT proportionally of its dimension is lighter and cheaper, so correspondingly the electricity production is cheaper. Being lifted in the sky, the wind velocity is bigger following exponential Hellmann law, while the HAWT power is in cube of wind velocity being more than 10 m/s at 500-900 m above open ocean surface. Low point of such device be fixed by a rope to a float stabilized in constant position.. The lion share of such electricity cost is a cost of electric generator of 30 Wat...
