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.

pLEASE

YES

This sounds awesome.

this is all cool for the energy but wouldn’t it be nice to see beyond the road on the sides still? to see if any people/animals cross the street last minute?

This chart has one misleading bit. You don’t really overdose from cocaine. The vast majority of deaths from cocaine occur from an impossible-to-predict fatal heart rhythm. You snort some coke and your heart stops beating normally and you die. Cocaine is an interesting drug in that this rhythm can occur in anyone at any time and it’s not associated with the dose. It can happen the first time you do coke or the 1,000th. It can happen with just a small amount or it can happen after your 4th hit that night. It’s just sheer bad luck. Note that cocaine kills more people than heroin every year.
