We have developed the Shadows and Light solution to help stop the waste of streetlight energy every night caused by these passive installations. By using an LED light source and by powering it with accumulated solar energy, we eliminate this pointless waste of energy.
Further, by supplying the unit with a wireless network and a smart traffic surveillance system, we make the traditional passive installation active. Now, a streetlight is no longer just a low-tech mast with a light bulb, that drains our energy sources, it becomes an intelligent peer in your local environment.
The smart and green streetlight solution
The Shadows and Light system is truly a green product,with zero CO2 emission and without any need for an external power sources. In contrast, a single conventional streetlight stand consumes between 500W to 1KW, making the consumption up to an average of 6KWh per day. The CO2 emission for producing 1KWh is 478Gram (average in Denmark 2012), or approx. 1/2kg/KWh. That results in an approximate CO2 emission of more than 1000kg per year per lamp. Even small cities can easily have more than 5000 streetlights, making the CO2 emission just outrageous.
But its more than a green project. It is also a smart project! A streetlight stand is a heavy installation, and we think its a pity to see that this construction is used only to light up the street. We have therefore extended our streetlight head with a scaled-down version of a wireless network solution developed for rural areas (see http://www.shadowsandlight.org). Again, this network is purely powered by accumulated solar energy.
Having access to an IP backbone we can deploy wireless Internet service to the entire street and the surroundings at low incremental cost to the benefit of local citizens. And it gets better: By installing a high-resolution digital camera module in the streetlight head, we can monitor the activity of the streets further adding a smart traffic solution. This may, for example, guide cars and trucks to avoid rush hour traffic problems, again saving the environment from pollution and noise.
Depending on local political and cultural preferences, an optional video camera may also be used to provide regular video surveillance, thereby minimizing the risk of crime for local citizens.
What results can you expect from this project?
We have developed a working prototype of the complete Shadows and Lights solution and your contribution will be spent on creating a trial system with one or more vocational schools, who today have no streetlights and no cost-effective Internet connectivity. More specifically, we will design the first manufacturing series of the product, and work with our manufacturing partners to develop the first 3-20 smart streetlights, depending on the funding raised with your help :-)
We will constantly update all contributors with a weekly status on Twitter of our roll-out and using our dedicated Android and iPhone app, you may monitor the approximate amount of energy and CO2 emission saved in real-time.
Obviously, you do also help save the environment by cutting down emissions, but we know that the Shadows and Light Project can’t cure all evil in the world, and more effort has to be engaged in new and innovative environment friendly technologies. But we have to start somewhere, and the streetlights may not be a bad choice. With the huge power consumption of every streetlight, and with the incredible number of streetlights across the globe, it WILL make a difference. Just think about a normal city with 10.000 streetlights. Deploying Shadows and Light Smart streetlights will in this case save more than 1M kg CO2 a year…
Solar powered streetlights are expensive and probably not a reward that most people would want anyway, so instead we are offering a Shadows and Light branded solar pocket/desk/emergency lamp, that will even charge your phone. We hope you will use this handy little solar lamp and think of the good cause that you are supporting!
In addition, we have teamed up with the Icelandic designer Snaedis Björk to create a t-shirt that will hopefully make you feel part of the "team". Please note that the photos below are just simple sketches, the final design will be much nicer!
Who are we?
Knud Erik Skouby
Professor and Director, Aalborg University, Center for Communication, Media and Information Technologies.
The Shadows and light team is a group of dedicated and concerned engineers. Some of us have a background from various international companies like Nokia, Ericsson, Openwave Systems, and Litepoint. Some of us are running start-ups in SW and HW business. Some of us have academic careers, as researchers and professors at internationally recognised universities. Altogether, we share a common vision: The world should be better connected, and last longer!
We make various network solutions for areas of the world, where power outlets don’t exist, where telecommunication is something you can only dream of, and where an Internet connection to the world means development, prosperity and the future. All our network solutions are solar powered, and easy to deploy under extreme conditions.
Based on this technology base, we have developed a complete new and green streetlight concept. Our solution is utilizing the latest LED technology to reduce power consumption, All power used is generated from sustainable energy based on integrated solar energy panels. And, on top of this, we have integrated a wireless Internet hub and a smart traffic surveillance system into the streetlight head, making it smart and an active peer in the local environment
How will YOUR money help the project?
We are idealists, but we are also business people. We believe, that CO2 neutral solutions of the future needs a little help to get out there, and only when we have made good test deployments, the world will “see the light”. We will use your contribution to make the final pilot tests – on location - in 3 cities where there is a need for an innovative solutions to light up streets and a connect communities to the world.
By investing in this green energy project, you do not only help our environment, but do also help people living under tough conditions to connect to the world. You will get access to our Smartphone App, showing you where the Shadows and Light solution is installed, where we have planned installations, and how much CO2 we have saved together, calculated in kg’s, m2, and years we saved the planet (based on the COP15 calculations).
Risks and challenges
An important risk in rolling out streetlights in the developing areas of the world is the need for commitment from local governments, e.g. city municipalities. Some of these governments may have business relationships with suppliers of conventional passive and power consuming products who represents a strong and well established industry.
However, we have years of experience making and selling environmentally friendly network solutions to areas of the world that, without these solutions, would be completely disconnected. Using this experience we will find a way to move these communities into the new connected world with telephony and Internet.
We will do our best to promote, negotiate, and work with local companies and global NGOs to establish the business foundation for our green technology
