Novel Solar Absorber to Improve Efficiency of Concentrating Solar Power Technology
by Erica Solomon
Published 6/8/2016 on Masdar Institute News at

  • Researchers at the Masdar Institute and MIT have developed a new technique that can raise the efficiency of a solar absorber to almost ninety percent.
  • The technique involves piercing a solar-absorbing film with a pattern of very fine holes (less than 400 nm diamater).
  • The nano-porous absorber can absorb a broader range of wavelengths than traditional absorbers, and also uses less material – it has only two layers (a metallic layer over a semiconductor) with a total thickness of 170 nm.
  • The ultrathin film also exhibits low radiative losses.

3. Organizational Stakeholders

This technology is still in the research phase, but has potential to affect the following stakeholders:

  • Manufacturers of solar absorbers/collectors
  • Utilities using solar collectors to generate electricity
  • Building owners who could use thermal energy collected by solar absorbers for space and water heating

4. Deployment

The next three stages in deploying this technology could be:

  • Researchers: optimize metallic coating to reduce costs of manufacture
  • Manufacturers: manufacture modular units using the ultrathin film technology
  • Building owners and developers: phase in solar thermal panels to replace heating-oil technologies


Smart Sets the Bar High with Sustainable Vehicles


– GHG emissions, waste from car parts, energy use, water use, safety and health.

These are sustainability issues that all car manufacturers have to deal with.  Smart aims to solve these.


– Environmental protection is one of smart’s top goals.  The outer layer is 100% recyclable plastic.  Also, each car is constructed in modules for easy dismantling .

– As for safety, each car contains a steel housing that combines longitudinal and crosswise framing that displaces impact forces over a large area of the car.

– The car also features excellent fuel economy that will consume less fuel, resulting in less greenhouse gas emissions.

– Smart uses powder coating, which is a dry powder that does not require a solvent.  This uses 40% less energy and conventional painting methods and no water is consumed or wasted.


– Car companies, consumers, engineers, suppliers, designers


– Smart should increase marketing outside of France and Germany to increase global awareness.

– Add in child friendly features, such as a section for a car seat.  Making a new model of this car that is family friendly will make this car feasible for almost any consumer.

– The cost is a huge plus for smart.  They should easily be able to market this car in developing countries, as it is affordable, uses minimal fuel, and is recyclable.

Piñatex, Something you didn´t Know about Pineapples

Screen Shot 2016-06-22 at 8.07.33 PM


Conventional leather production involves a process called tanning in which different chemicals are used to make the leather soft an attractive to the consumers. Evidence has been found that many of these substances are very harmful to the environment and the health of the workers and the communities where tanning operations are held. Chromium VI is one of the most widely used chemicals and it is believed to cause skin rash, kidney and liver damage, respiratory problems, and various types of cancer among others.


Piñatex is a “non-woven textile made from pineapple leaves´ fibers”. This technology is an alternative for conventional leather due to its durability and texture properties. Piñatex is a sub-product of pineapple production that uses the leaves that are left on the field to rotten. This makes the process very sustainable in the sense that no extra land is needed for it.


  • Textile industry.
  • Tannery workers.
  • Health authorities of leather intensive communities.


The product is fully developed, but it is in constant development to achieve a greater potential. So far brands like Puma or Camper have backed it up by using Piñatex in their products. The project is ready to go to the next level for which funding from either the private or the public sector could be useful.

Public lighting is everywhere but connected lighting is not?

IoT: Public lighting is everywhere but connected lighting is not.

  1. Sustainability Problem

Energy Efficiency

Lighting, beyond illumination, is an energy related asset. There are about 300 million street lights worldwide. On average, public lighting is more than 20 years old. Lighting can account for up to 40% of city’s total energy consumption. -1% of installed systems, are connected, expected to grow at 16% per year. Over the past year, we’ve seen IoT-enabled innovations enter our homes, cars, phones, and air space – and even appear on our bodies. Will they make our lives safer, simpler, healthier, and more environmentally responsible?

The Internet of Things: Turning $3 Lightbulbs Into A $60 Billion Opportunity1

By Shelly Dutton

From this article, we learn how connected public lighting can be a driver for the digital transformation of cities and join the Internet of Things (IoT) revolution. See how Dutch company Koninklijke Philips N.V. partners with SAP to empower the digital transformation of cities as they become safer and more livable and energy efficient.

The idea was a reimagined commodity that we all rely on, opening the door to a $60 billion market opportunity. Philips is refurbishing streetlights, parks, bus stops, buildings, and bridges around the world with LED lightbulbs. But these are not just standard $3 lightbulbs – they’re connected and controlled through a remote management system.

Cities can now keep their residents safer by monitoring storm drains during heavy rains. They can even adjust lighting levels to strike a balance between public safety and costs related to energy consumption and maintenance. More important, they’re making the world safer, brighter, and a little more beautiful.

  1. Deployment

To set the stage for the connected lightbulb market while helping cities and towns benefit from digital transformation, the public segment leader at Philips Lighting discussed:

  1. Assets will need to communicate so their behavior can be flexibly adapted; therefore, verify on: How many assets are there? What state are they in? Are they working when they are supposed to or not working when they are not supposed to? How much energy do they use?
  2. Measure the energy used while monitoring lighting as they change the behavior of the environment over time to ensure energy efficiency and right amount of light at the right place at the right time. Connect assets to be able to manage them remotely. Two trends: (1) Switch from analog to digital (LED) light points with microchip for communication, tracking and connectivity; (2) Employ business model involving third party service provider. This needs:
    1. Connected lighting for transparency
      • Create proprietary networks (i.e. RF or powerline networks)
      • Deploy light points by embedding cellular network into the device now available publicly
    2. Measurement and verification systems in place such as EPC (Energy Performance Contracting)
  3. Unlock potential of IoT and think about the market opportunities in cities. More and more people will be living in cities which are close to innovation age.
  4. Need partnership: Philips partnered with SAP to use IoT technology for better outcome. Philips focused on the potential of IoT market while SAP focused on the future of city program for innovative, smart and digital city. Both focused holistically on how city can become digital, smart, green and resilient cities because 80% of the energy consumption, as well as GDP, are generated through cities.

To be successful, keep in mind cities core functions are: 3 Ps – Protection, Proviision of Services, Prosperity. Cities must deliver value and protection is a key aspect. Cities are the heart of the challenge we face in the future.


Looking in tech enabled value to enable value allows the understanding of how to monetize and unlock the potential of IoT in the cities market for urban resilience, and protection against climate change, terrorism, crime, shocks, etc.

Provide Services:

Look into how IoT can improve the lives of the people in those cities such as by providing waste services, safety, water, lighting, etc.


For business outcome, how can IoT technology reduce risk of fire, flooding, and improving management of the infrastructure?

Some examples of implemented Philips CityTouch infrastructure:

  1. Kristiansund in Norway has 5,500 light points and outages are fixed in no time.
  2. Buenos Aires, has 91,000 light points, was a partnerships with Philips CityTouch and SAP Hana. Implemented by combining real time data from connected street lights with data from other assets and sensors in a single integrated city dashboard.
  3. Empire State Building of NY changes peoples’ state of mind through color transformation lighting. On the Commencement Day of Columbia University, lighting is turned to blue and white.
  4. Miami Tower in Florida is a business case that proves savings of $ 0.25 M per year.
  5. Bay Bridge in San Francisco implemented responsive lighting in which pattern is connected to city rhythm, i.e. traffic, wind, and they come together in algorithm to reflect the pattern of lighting in the bridge.

Carbon Emissions Turned into Stone

Sustainability problem: 

CO2 released when burning fossil fuels leads to global warming


Turn carbon capture into stone and store underground!

    • In Iceland, scientists turned carbon into stone by  pumping a power plant’s carbon dioxide into underground basalt and mixed them with water.  The process chemically solidified the carbon dioxide and changed the basalt and CO2 into a chalk like substance.
    • The solidifying process takes 2 years, whereas it was originally assumed to take decades.
    • The solidification resolves the risk that carbon stored underground as gas or slurry could accidentally be released into the atmosphere.
    • Its currently unclear whether the process could work with many types of basalt or saltwater as opposed to freshwater


    • Governments trying to meet CO2 cap commitments
    • Power plants trying to limit CO2 due to regulations or cap and trade limits/incentives
    • Citizens who benefit from avoiding the impacts of global warming
    • Coastal cities/regions and other high risk localities that have to plan and pay for warming mitigation and adaption

First 3 steps for deployment:

    1. Additional studies of types of basalt and water required for the reaction (including testing factors that affect the duration of the reaction)
    2. Analysis of potential geographic locations and power plants that have the proper basalt formations and could make use of the technology
    3. Cost analysis and funding models to determine how much the technology will cost to use and which stakeholders should contribute to the costs
