Detection of Atmospheric Cherenkov Radiation Using Solar Heliostat Mirrors

, 1996
The gamma-ray energy region between 20 and 250 GeV is largely unexplored. Ground-based atmospheric Cherenkov detectors offer a possible way to explore this region, but large Cherenkov photon collection areas are needed to achieve low energy thresholds ...

A Comprehensive Study on Hydrogen Production via Waste Heat Recovery of Gas Turbine Cycles in Cogeneration Power‐Hydrogen Layouts: 4E Study and Optimization

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The efficient utilization of waste energy in gas turbine (GT) cycles (GTCs) is a crucial aspect of sustainable energy production. While previous studies have explored various aspects of waste energy recovery, a comparative analysis of different bottoming configurations has been lacking.

Heliostat cost reduction study. [PDF]

, 2007
Power towers are capable of producing solar-generated electricity and hydrogen on a large scale. Heliostats are the most important cost element of a solar power tower plant. Since they constitute {approx} 50% of the capital cost of the plant it is important to reduce heliostat cost as much as possible to improve the economic performance of power towers.
