it’s an awful truth that suffering can deepen us, give a greater luster to our colors, a richer resonance to our words. That is, if it doesn’t destroy us, if it doesn’t burn away the optimism and the spirit, the capacity for visions, and the respect for simple yet indispensable things.

New streetlamps could improve your view of the stars.
A new paper published in the journal Optics Express describes a system for focusing light from streetlamps directly on the area required, with almost no light leakage horizontally or vertically. Conventional street lamps scatter up to 20% of their energy away from where it is required, not only wasting power but also leading to light pollution which obscures your view of the night sky.
The proposed LED lamp uses a lens to limit where the light is projected, with a reflecting cavity to recyle light that would otherwise be wasted. The team thinks the system would use between 10 to 50% less power to illuminate a section of road than current LED streetlamps, which are already more efficient than regular lamps.
A prototype is being developed and is hoped to be completed this October.
This sounds awesome.
