Solar energy generation in three dimensions

Solar Energy Generation in Three Dimensions

We formulate, solve computationally and study experimentally the problem of collecting solar energy in three dimensions. We demonstrate that absorbers and reflectors can be combined in the absence of sun tracking to build three-dimensional photovoltaic (3DPV) structures that can generate measured energy densities (energy per base area, kWh/m) higher by a factor of 2–20 than stationary flat PV p...

Mass Generation in Three Dimensions

I consider the dilute monopole gas expansion of the three dimensional Yang-Mills-Higgs system in the symmetry broken phase. The functional determinants which occur in such an expansion are computed in the heat kernel approximation for an arbitrary SU(N) gauge group. Explicit expressions for the gauge boson mass in the unbroken gauge sector and the string tension are obtained for the SU(2) gauge...

Energy-efficient motion camouflage in three dimensions

Recent observations suggest that one insect may camouflage its own motion whilst tracking another. Here we present a strategy by which one agent can efficiently track and intercept another agent, whilst camouflaging its own motion and minimizing its energy consumption.

Solar Nuclear Energy Generation and the Chlorine Solar Neutrino Experiment

The study of solar neutrinos may provide important insights into the physics of the central region of the Sun. Four solar neutrino experiments have confirmed the solar neutrino problem but do not clearly indicate whether solar physics, nuclear physics, or neutrino physics have to be improved to solve it. Nonlinear relations among the different neutrino fluxes are imposed by two coupled systems ...
