Parabolic reflectors for solar applications are nice stuff ... After you´re done with this, you end up with a nice flat mirror. Here´s where the vacuum is needed to force the film into parabolic ...

Parabolic reflectors are pretty handy devices ... suitable commercial dishes aren’t that hard to come by. But a big, shiny mirror for your solar death-ray needs is another matter, which is ...

Why do we need solar panels? We can have photovoltaic ceramic instead, as this invention could replace photovoltaics as we ...

Parabolic mirrors offer excellent correction of spherical aberration. Parabolic mirrors can either be on-axis or off-axis. On-axis parabolic mirrors produces collimated reflected light. Off-axis ...

parabolic mirrors - used in China 3,000 years ago - could focus the Sun's rays to grill meat. Solar thermal systems used winter sun to warm air or water that could reduce heating bills.

Also called a "dish" or "mirror," parabolic antennas are used for satellite signals and planetary telescopes. The reflective mirror design can also emit energy such as in a flashlight or ...

The focal point of Nevada Solar One can be found in parabolic trough solar collectors. These 760 collectors each have more than 182,000 mirrors and operate by focusing solar rays on a collector pipe.
