Traffic Light Directional Device for Blind Persons Usage for the Traffic Light Poles with Lights Facing 2 Directions
When blind persons (BP in further text), approach street crossroads with trafffic lights, they usually face the issue, how to detect WHICH beep sound is for WHICH direction? Beep sound is the same for both directions, although there are some tries to make 2 different beeps,
This turbine differs that has two additional elements - a turbo-expander in the center and jet cuts on blades. The turbo expander absorbs wind energy. Thus the non-working center of the turbine becomes effective. In some versions, the fairing itself will have grooves absorbing wind energy.
Air-conditioning systems spend most (up to 90%) effort on cooling air. Cooling people is just a byproduct of the whole process. To reduce energy demand we need to implement approaches that reverse this situation and focus on directly cooling people with minimum conditioning of surrounding air.
There is a huge energy expenses for a motor pump or submersible pump to lift water from an underground reserve tank to rooftop water tank. Not only is it expensive but air pollution is created (indirectly for power generation). Except it, the supplied water from govt.
Z-PEC Zero–Point Energy Converter
According to Quantum Electrodynamics, otherwise empty space is filled with tremendous energy; it’s called the Quantum Flux or Zero-Point Energy. Z-PEC will mechanically tap this unlimited resource for pollution-less electrical generation and pollution-less vehicular-propulsion.
