A multilayer semiconductor scintillator is disclosed for detection, energy quantification, and determination to source of high-energy radiation, such as gamma or X-ray photons or other particles that produce ionizing interaction in semiconductors. The basic embodiment of the inventive detector comprises a multiplicity of stacked direct-gap compound semiconductor wafers, such as InP and GaAs, each wafer heavily doped n-type so as to maximize its transparency to scintillating radiation. Each wafer is further endowed with surface means for detection of said scintillating radiation, such a hetero-epitaxial p-i-n photodiode.

A vertical axis wind turbine that utilizes a unique semi-circular, angled, scoop design and frame to fully harness wind energy. The shape of the scoops maximizes wind collection while minimizing wind resistance. The angle of the scoops allows the wind turbine to catch wind, including updrafts, to produce a rotational and balanced lifting force on the scoop system. This balanced lift is possible due to a stable frame which maintains a fixed position of the vertical axis.
