The utility model consists of an electricity generator with drinking water, discharging oxygen and hydrogen based on the differential electronegativity phenomenon of chemical elements, which uses drinkable water to transfer the electrical loads. The novelty lies in the fact that by using electrodes having particular physical structures, made of different materials and adding a condenser, an alternative impulse generator and a doubler or a voltage multiplier useful, stronger power is achieved. In this process, water electrolysis takes place concomitantly, gas bubbles appearing in the two electrodes. As we know, oxygen is discharged to the anode, in the case in point, the aluminium electrode, and hydrogen to the cathode, in our case the copper electrode. In a larger generator, these gases may be collected and used to produce heat energy or in industry, agriculture, medicine etc. It can be used in any field of industry, agriculture, medicine, household etc.

The invention refers to a process for rapid manufacturing that uses a focused ultrasound beam according to the invention. The process is based on the local ultrasound welding of the material (2) grains that is under a powder form, welding that takes place solely in the focal spot of the focused ultrasound beam, the focal spot being scanned across the X-Y-Z directions within the powder (2) bed so as to 3D build the entire object (7) that is desired. The processes taking place in the focal spot region are local melting, local melting due to friction followed by filling of the gaps existing between grains, removal of the grain asperities, local inter-diffusion between neighboring grains as well as other phenomena that take place at the interfaces between materials when these are subjected to an ultrasound field.
