The Optic-ID technology is now finalized. It is the first impossible to forge signature, the answer to the major security need felt by consumers and businesses, across new services.

Main applications are fighting counterfeiting and document fraud.

Latest improvements of the method enable on-line identification of an individual who is invited to place a Smartphone at different locations around a card. The scenario is impossible to replay.


VAGUE vortex turbines

This method enables manufacturing automatic stepped gearboxes whose transmission ratio automatically varies according to the transmitted torque.The principle is to cause a rotation of the fluid in a stator (on the left), to accelerate it by reducing the section of the duct, and to use this rotation to make a rotor turn (in red). This rotation is converted into electricity. A cone located at the outlet can create a depression which further improves efficiency.

The speed of rotation increases near the axis of rotation of the rotor in inverse proportion to the radius of the rotation, while the force created by the fluid on the rotor blades varies with the square of this speed. This is what makes it possible to be satisfied with a low speed of the fluid (water or air) to obtain significant electrical energy.

Above left is a hydraulic turbine that just needs to be placed in the flow of a river to obtain electricity. It is fixed by a cable to an anchor block which can receive the electric batteries, and wings keep it midwater. There is a "small debris door" (shown as darker part) that allows the debris which would have passed through the entrance grid to leave upstream of the stator and the rotor. The same method applies to the wind turbine shown on the right

An important advantage of this solution is that no masonry work is necessary, and that the hydraulic turbines can be mass-produced in a factory, while their maintenance is greatly facilitated.
