Theoretical limit of solar cell effeciency probably broken



"A simple, single nanowire crystal is capable of super-concentrating the intensity of the sunlight that it is exposed to up to a factor of 15, researchers from the Niels Bohr Institute have discovered. The surprising discovery means that the assumed limit to solar cell efficiency, the “Shockley-Queisser Limit,” can likely be increased. The discovery should…

H-Cell 2.0 Hydrogyn fuel cell hybrid power-train for RC models

This might interest some of you.







A hydrogen fuel cell hybrid power-train for 1/10 scale model hobby RC. The H-Cell 2.0 can be connected to almost any RC platform and will provide continuous power to recharge the on-board batteries. Using this hybrid system it is possible to increase the run time of RC vehicles by more than four times!



When the solar panel option is…
