A scalable parabolic or disc shaped mirror, that is formed and maintained by inflating, with air or inert gas, a rigid polymer membrane envelope, that is pre-formed, and such that when inflated, forms this parabolic or disc shape, governed by a center supporting pole, and ring around circumference of the mirror. The top half of the ballooned envelope is made of a clear transparent membrane through which the sun's rays pass through and on to the lower inner lower surface, which is coated with reflective surface. The balloon is skewered through the middle of each membrane, and clamped with flanges to hermetically seal the envelope. The pole or center structure is anchored and hinged at the base so the Pneumatic Mirror can be articulated to face towards the sun, thus focussing the energy to whatever device is at the focal point.

An adjustable support for a panel is provided to allow control of the height and the tilt angle of the panel. The support includes a hollow cylindrical base having an outer diameter D.sub.1; a first hollow piston having an outer diameter D.sub.2 threadably engaged with the base; a second hollow piston having an outer diameter D.sub.3 threadably engaged with the first piston; a third piston having an outer diameter D.sub.4 threadably engaged with the second piston, such that D.sub.1>D.sub.2>D.sub.3>D.sub.4. A ball pod extends from the third piston and accommodates a ball attached to the panel. One or more stepper motors are provided, where each stepper motor is coupled to a bottom portion of a respective piston, and a rotor of each stepper motor is configured to rotate the corresponding piston, thereby causing the piston to move along a longitudinal axis of the support.

The invention relates to a passive tracking device for tracking the position of the sun, which comprises a hollow parallelepiped casing through which the solar radiation entering through a first lens located at the upper end of the parallelepiped casing passes towards a discriminating reflector arranged at the lower end of the same casing; the tracking device redirects as much incoming radiation as possible towards side chambers for absorbing radiation, heating a working fluid contained in the side chamber; producing a volumetric expansion in the working fluid that, communicating with shafts for the rotation of the tracking device, allows the orientation with the normal/perpendicular position with respect to the position of the sun, and to guide the alignment direction of other tracking devices for collecting energy in devices for collecting photovoltaic and/or thermal energy that are mechanically connected to the tracking device.

A process for enhancing boiling to generate steam and superheated-steam by using renewable energy from Concentrated Solar Power. Steam can generate electricity, heating and cooling, sterilization, and other processes and products. The embodiment is made of a light weight small assembly and rotates on the X and Y axis to align with the solar radiation. The assembly has a steam generation unit (28) with Fresnel lenses affixed to concentrate the solar radiation and generate heat. The focal point of the radiation being concentrated is directed to the inner side of a glass tube (30) covered with nanoparticles. The surface area being heated by the solar radiation is increased by the use of nano articles. Water atomization/aerosol unit (60) creates reduced size water droplets that are channeled to glass tube (30) and put into contact with the heated nanoparticles. The atomized/aerosol water droplets help reduce heat dissipation.
