The Solar Bottle Light: Using Water and Bottles To Create Light Bulbs

Solar Bottle Light Bulb

Solar Bottle Light Bulb

I have highlighted before the innovative solar tubes (closet lighting ideas) which brings in natural lighting through the roof during the day. A cheaper and simpler option, a 1.5 liter solar bottle light, is being used in rural and poor areas around the world.

For a lot of people around the world, just turning on one light bulb can be a major expense. Their homes are not well designed, so it can be a dark place even during the day. Now they can have an inexpensive lighting solution during the day (costing $1 to install in the Philippines). A 1.5 liter soda bottle is filled with water and a little bit of chlorine or bleach. A hole is then cut into the roof where these bottles can sit.

The water reflects the sun light in all directions (it is equivalent to a 50-60 watt light bulb), whereas just a hole in the roof works as a spotlight and doesn’t light up the whole area. The Chlorine or bleach prevents algae or bacteria growing in the water.

Washing a City with Red Lights for World Aids Day

The city of Rio De Janeiro was awash in red light to mark World AIDs Day, which was on December 1st. Monuments across the city, including the iconic Christ the Redeemer, were lit up in red for 3 days. Seeing such a major change around the city was a great way to raise awareness about AIDS. Like many cities and countries, the topic of AIDs is filled with myths and prejudices. This $1.1 million campaign by the city of Rio, which also included offering testing, looked to change that and provide people with the correct information.

Other countries – Argentina, Australia, Great Britain, South Africa, Canada, and the US also took part in the campaign. World AIDS day pictures from around the world:

Operation Christmas: Fighting War With Christmas Lights

Operation Christmas

What is the best way to speak to guerrilla soldiers? How about through 2000 LED Christmas lights? Columbia has spent 60 years in turmoil with a guerrilla group. Knowing that Christmas, even for guerrillas, is an emotional time an advertising agency came up with an idea to send a Christmas message in the deep jungles of Columbia. The short video below shows how they achieved to demobilize 331 guerrilla soldiers during Christmas of 2010.

The Importance of a Light Bulb: Home Security Lighting

Light Bulb

Can a single light bulb fight crime?  Diana Lowery, a councilwoman of Stockton California, is campaigning that residents have a light bulb near their front door that is left on during the whole night. The campaign goes the extra mile by enlisting corporate donors (Siemens and Pacific Gas and Electric), which allows for the residents to pick up a free energy efficient light bulb to use as outside security lights for a house.

Stockton California

The campaign was started due to record levels of crime due to a poor economy. 55 people have been killed in Stockton this year. This idea allows residents to play an active part in fighting crime. Though it won’t solve the problem, Diana believes it will only help the cause. Running one of these bulbs by the front door will cost residents a mere $12.46 per year, a small price to pay for an increase in safety. The Interim Police Chief backs this idea, as streets that have exterior security lighting will deter crooks – hence the slogan “Light up the night, Crime hates the night”.

The Importance of a Light Bulb: Energizer Partners with One Million Lights

A great example of a corporate social responsibility case study is seeing Energizer partnering with One Million Lights, a charity that seeks to “improve the daily lives of children and adults by providing clean and healthy lighting.” In a global population of around 7 billion people, 1.6 billion live without electricity. Instead, kerosene lamps which produce toxic fumes are used to light up their nights. Light is essential for kids to study, for a mother to give birth at night, or for families to do chores and jobs. One light bulb could change a family’s livelihood.

social responsibility case study

So Energizer is donating 11 million hours of solar lighting to communities living without electricity in Latin America, Philippines, Kenya and Ethiopia. These solar lights will provide free and healthy lighting. To raise awareness for this cause they are hosting Energizer Night Race for a Brighter World – a number of night races across the world.

The Power of Sunlight: Inflating a Temporary Sun for the Winter

Tropicana Sun

A lack of sunlight can cause a number of issues, such as seasonal affective disorder (a form of depression) or a Vitamin D deficiency. With this in mind Tropicana Juice created a campaign that ended up bringing artificial sunlight to a cold and isolated part of Canada.

Bringing Sunshine To Dark Winter Days

Tropicana artificial sunlight

Inuvik, a small town in Canada of only 3,500 residents, goes without sunlight for weeks during the winter months. So in the winter of 2009/2010, Tropicana went to Inuvik and in the morning brought an artificial sun to life. A 36 foot wide helium balloon was inflated, giving off 100,000 lumens – seen all across the town. The tv commercial shows real people and real emotions. Tropicana also spent time in the community – giving out their orange juice to residents and talking about the effects that a lack of sunlight can have on a person.

Their message is “Brighter mornings make for brighter days
