Don’t just recycle that old plastic bottle — turn it into a lantern. At least, that’s what the folks over at Liter of Light are doing. The organization is helping developing communities the world over create their own light sources using nothing more than old plastic bottles, demonstrating just how far you can go when you reduce, reuse, and recycle.

Described as a global, grassroots movement whose aim is to provide affordable, sustainable solar light to those with limited or no access to electricity, Liter of Light depends upon a vast network of partnerships the world over to teach communities how to use their waste to light up their lives. The organization says that it’s been teaching “green skills to empower grassroots entrepreneurs” since its founding back in 2012, and its open-source technology has been lauded by the UN and applied in some UNHCR (United Nations High Commissioner for Refugees) camps.

By filling plastic bottles with water and bleach, the organization is able to create day lights — the bottles are attached to roofs and refract sunlight during the day. And when nightfall arrives, a micro solar panel added to the plastic bottle enables a night light powered by the sun.

Best of all, all the parts Liter of Light uses are available to the local community, which means that residents are empowered to create light of their own.

The initiative began just five years ago in the Philippines, and already, has a presence in more than 15 countries. But the goal is far more ambitious — Liter of Light hopes to reach 1 million homes in 2018 (thus far, it has already reached 850,000 homes).

If you’re interested in taking part in Liter of Light, you can either donate directly to the cause, or learn how to create one of these lights yourself.

Weather alerts may be the smartest use of smart lights. They can save your life
LIFX Mini Color bulb installed in ceiling

Springtime brings with it fresh life, blooming flowers, and in some parts of the country, incredible storms. The old expression that March comes in like a lion and goes out like a lamb holds particularly true in the Southeast and Midwest, where spring storms are accompanied by damaging, dangerous tornadoes.

Meteorological science has advanced in amazing ways. People now have a much better idea when dangerous weather is on the way, but only if they pay attention -- and even then, it can sometimes be hard to hear the alert if there's a lot going on in the home.

Philips Hue makes it easier to manage smart lights with new module and switch

Anyone with a smart light has experienced this one particular problem: If you turn the wall switch off, your light is useless. Smart lights can turn on and off on their own, but if they rely on a power source from a wall switch, then a well-meaning friend or family member can flip the switch and throw all of your routines out of whack.

Philips Hue offers a solution through the Philips Hue Wall Switch Module. This module fits behind an existing wall plate and lasts for up to five years. It allows you to use your smart lights even if the switch has been flipped, and you can also activate your favorite scenes directly from the module. The Wall Switch Module will be available in summer  2021 for $40 for a single module or $70 for a two-pack.
