About landing of a kite-car as a second level of traffic Author: David Judbarovski, systems engineering, retired engineer, Israel judbarovski@gmail.com , Linkedin: David Judbarovski [3761]-19.08.2017 The kite-car can be a key element for middle range traffic up to about 700 km long with cruise speed of about 350km/h (see “Progressive Transportation Manifesto” http://judbarovski.blogspot.co.il/2017/05/progressive-transportation-manifesto.html or http://judbarovski.livejournal.com/141099.html , 2/05/2017 ). Its landing can start at about 120 km/h with a quite short landing way. So for the landing simplifying and reliability the back wheels of the kite-car have to be some nearer to run-way level than front wheels.  

Energy and water production by artificial condensation of vapor above LCL Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com , Linkedin: David Judbarovski 13.08.2017 Energy and water production by artificial condensation of vapor above LCL Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com , Linkedin: David Judbarovski 11.08.2017 Humidity being above the LCL (lifted condensation level), is looked much more concentrated and cheap resource, than water droplets harvesting by meshes. I consider a horizontal thin film to be placed above the LCL, and it is enough for the dew fall on the film surface at both sides of it, and some big layers of the films, are one above others with a gap between them allows practically all air humidity to be harvested by all height and width of the said construction. The layers are sloped to their central axis, and the water condensate are flow

The layers are sloped to their central axis, and the water condensate are flowing to the ground level and moves an electric generator to produce a plenty quantity of electricity. Such water and electricity would be much cheaper, than conventional tariffs for them.    Large hy

Interactive writing on display in a form of small and thin card Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com , Linkedin: David Judbarovski [3754]-29.07.2017   Here can be considered an additional step to help for realization of my prediction earlier offered in my article ”The World after The Paper” ( http://judbarovski.livejournal.com/140703.html   later was repeated in http://judbarovski.blogspot.co.il/2017/08/the-world-after-paper.html ). The key element of it can be a “pen” with a tiny electronic sensor of motions of a writing end of the pen. It can be extremely tiny electronic sensor of accelerations twice integrated to create a digital signal of the trajectory of the pen, if the pen contacting with a surface of the said display. The said signal can be stored and/or transformed into 2D image on the said display can be small and thin card, but with a battery, a control and a port analogous to USB. We can shi

The World after The Paper Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com, Linkedin: David Judbarovski Now It is a true moment for developing and commercialization of a conceptually innovative device (hardware and soft and their new functions and “integrateability” with other devices and systems). The above-mentioned device must be a necessary and inalienable attribute of our civilization and personal life as it was earlier with a paper during more than thousand years, but substitute and exclude comprehensively the paper carrier by much more comfortable and reliable in usage product for writing, printing, reading, storage and as a legal documents of all sorts, including the money too. Even if as idea it goes back to very earliest stage of electronics era and now it is existed in various alternatives as necessary and inalienable attributes of our life, but last level of information technics and technology allows to open a new
