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.
The problem statement chosen was to build a model that makes sure that the rules for the speed limit are followed in every road segment and thus reducing the possibility of accidents and ensures safer automobile systems.
My prototype has two functions in one: protect yours car door from being hit by other cars doors or by a shopping cart. It is novel because it will come handling to put on and will be at low cost and safe.
There is a lot of need for green clean and cheap fuels in the world. The main source of energy for 150 years has been fossil fuels. However, the world is running out of this source rapidly and there are detrimental effects of its use e.g. pollution and economic impact.

Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications, Very Low Frequencies (VLF) band signals have large EM wavelengths that can penetrate the plasma sheath layer with minimal loss,
Umbilical Care is an L-shaped silicon cord clip used to test the bacterial infection at baby’s cord. Via the “histamine testing sticker” attached on a hollow chamber of Umbilical Care which can react with the histamine produced by bacteria, medical staff and mothers can deal with cord infection when an orange sad face is shown.
Innovative cycles in the emergence of fundamentally new types of gyroscopes last for a period of forty to fifty years, and the change from one to another occurs only after a serious breakthrough in physics and technology. Gyros can measure the course of a scientific revolution.
Today offered a fundamentally new type of power astatic gyroscope.
Experts have estimated that 8.3 billion metric tons of plastics have been made and approximately 5 billion metric tons have already been discarded, with an abysmal recycling rate of only 600 million metric tons. Page 50 of 52
