Power Outage !!! Why not try Energy sharing ?

Energy is essential to life and all living organisms. With population explosion, rapid growth of industries and urbanization, there is an immense need to develop technologies/strategy for energy usage. Every year, 7 million customers experience power outages. Outages that last more than 5 to 10 minutes cost customers more than $80 billion each year. So here is a technology where in we could share the energy that is being produced by our alternative renewable energy sources like the solar panels or the wind energy during outages.

Sharing is caring. It is nice to Share..!!

  1. Sustainable Issue: Energy Sharing/Management
  2. Technology: Scientists have developed algorithms that would allow customers to use and share power from their renewable energy sources during outages. This can be done by strategically disconnecting devices, called solar inverters, from the grid.


During an outage, because of the perpetual connections with the grid, it is impossible for the owners to draw on power generated by their own renewable energy sources. A team of engineers from University of California, San Diego have developed an algorithm that would allow consumers to use and share power from their renewable energy sources. This algorithm has the capability to prioritize distribution of power from renewable resources. It can also be programmed to include priority functions based on different parameters. The equations in algorithm consider forecasts for solar and wind power generation as well as how much energy storage is available, including electric vehicles, batteries and so on. The algorithm combines this information with the amount of energy that the consumers are projected to use as well as the amount of energy that a cluster of homes/communities/businesses can generate.

  1. Stake Holders:
  • Public/ Government body
  • Urban planners
  • Corporate and commercial building users
  • Society/communities
  • Utilities
  1. Deployment / Implementation:
  • Step one: Showcase the reliability of the technology to the public, private entities and to the customers. Attract more investors and spread awareness about the usage to this technology.
  • Step two: Initiate regulation change nationwide, which would allow consumers to sell power to other business/residential owners.
  • Step three: Find companies / corporate that could use this technology in their buildings/businesses to demonstrate the efficiency of the technology. Until new regulations are in places this technology can be equipped with renewable power sources that would use constant power and do not have backup generator.
  • Step Four: Collaborate with the Public/Private governing body, urban planners and other organizations to integrate this technology to the communities.

Cleaning Our Oceans by Docfranco

Trash accumulates in ocean creating large garbage patches. If left to circulate, the plastic will impact our ecosystems, health and economies. I believe this technology can solve the issue of ocean garbage by cleaning up what has already accumulated in the ocean and needs to be promoted more by the government, intergovernmental bodies or independent private entities.

Using photosynthesis to convert CO2 into ethanol and ethylene

UNI – js5079 (Joshua Strake)

Sustainability Problems: Energy + Waste

  • The new technology enables sunlight to convert carbon dioxide into usable forms of liquid fuels, such as ethanol and ethylene.
  • Scientists at the Department of Energy’s Berkeley Labs developed the technology, which has reached efficiencies as high as 5%, reducing CO2 to a hydrocarbon end product over a certain amount of sun-time.
  • The technology can also function in low-light settings, although the main interest in this case would be the reduction of CO2 and the ability to use Solar-powered fuels at any time of the day, so whether o not the technology works at night isn’t as relevant, since the byproduct of the technology (the fuel) can be used at night. THis helps solve the issues must-take forms of energy face.
  • The main science behinf the technology is a “copper-silver nanocoral cathode” which breaks the CO2 down, and “an iridium oxide nanotube anode, which oxidizes the water and creates oxygen”.

3. Organizational Stakeholders: Scientists at Berkeley, Developers/Manufactuers, the Government (DoE project).

4. Three potential steps to roll out:

1 – Get better at it. (Achieve higher efficiency, optimize build and design)

2 – Standardize a means of production at large scales

3 – Engage utilities and contract developers to begin working the technology into the energy industry.

The Ginza Honey Bee Project

187d1084039f74f61d7f4e8cc66e29bb6c57f5b61) Sustainability Area: Civic Engagement

Problem: The Japanese honey industry is declining due to deforestation and the increasing use of pesticides such as neonicotinoids in rice farming. While other countries are also experiencing colony collapse disorder*, Japan is particularly vulnerable to the advanced age of its farmers and a decline in beekeepers. As honey bee takes vital function of pollination in ecosystem, decline in honey bee population is a problem of whole nature in Japan.

* Colony collapse disorder (Wikipedia)

 2) Technology and Deployment

  • This is not a type of cutting edge technology, but rather, a creative idea and activity named “The Ginza Honey Bee Project” based on civic idea how to cope with ecological problem by applying existing expertise and civic engagement in the middle of city and also stimulate local economy.
  • A group of community members in Ginza, a world-famous district for its luxury shopping and dining in Tokyo, and volunteers set out to connect with nature by establishing a rooftop beehive under instruction of beekeeper experts
  • The rooftop honeybee travels as far as two kilometers to collect nectar taking advantage of the flowers in residential Gardens parks and along sidewalks
  • The produced honey is sold in retail stores in Ginza district with its own brand
  • Since its initial harvest of 150 kilograms in 2006, the project has expanded its operation and increased its honey output to over one metric ton

The Warka Water Tower: Where Accessibility and Innovation Meet

The Warka Water Tower

1. Sustainability Problem: Water and Health

In today’s world, a growing population, global climate change and inefficient water infrastructure raises concerns for equitable access to clean drinking water. Currently it is estimated that 783 million people lack access to potable drinking water. Lack of potable drinking water contributes to a range of public health concerns such as spread of disease and illnesses, deaths, and inability to grow food.

2. Technology: Warka Water Tower

The Warka Water Tower was developed by an Italian architect named Arturo Vittori with his studio Architecture and Vision. It serves as an innovative technology to address concerns for access to water in developing countries in addition to their accompanying public health problems.

Summarized below are some key takeaways from this technology:

  • Warka Water Tower was developed to collect water vapor from the air in areas that lack sufficient water infrastructure for remote or developing communities
  • the device functions at the highest capacity in areas where humidity and fogs are high
  • depending on the conditions, the tower can harvest from 10 to 20 gallons of water daily
  • the tower can be built without electrical tools
  • this design is the winner of the World Design Impact Prize in 2016 and mass production is aimed for 2019

3. Organizational Stakeholders:

Stakeholders in this effort that would be relevant are the existing team of designers, architects, and developers. Additionally, marketing and investment teams would be beneficial to help Warka Water meet their goal of mass production in the year 2019. Outreach and construction teams should be assembled to promote these structures in developing countries to educate community members on how to construct and use the tower along with its other functions such as the Warka garden, drone, toilet, and house.

4. Next Steps

Warka Water’s next steps should involve assembling an investment and marketing team to gain funding for their innovative designs. This will allow them to bring the tower to mass production and enhance funding in their design and development of other Warka products. They should additionally consider NGO partnership to install and promote acceptance of this technology in developing countries.

Smarter Street Lighting


Problem: conventional legacy street lights in cities worldwide consume a large portion of a city’s energy budget, break down frequently, and require extensive maintenance costs.

Solution: adopting network-based LED streetlights provides an energy-saving solution that can also help mitigate maintenance lags and urban light pollution.

  • Chicago is replacing more than 250,000 (approximately 85% of the city) streetlights with smart LED units that promises to reduce energy consumption of existing lights by 50 to 75%.
  • The lights are connected by an IoT network that will enable dimming and brightening control and status monitoring to facilitate proactive maintenance and quicker responses for repairs.
  • Silver Spring Networks is an IoT network provider that was chosen by the city to partner with renewable energy company Ameresco. Silver Spring is providing similar street light modernization solutions to Paris, London, and other cities worldwide.


  • city and local government transportation/maintenance departments
  • utility companies
  • IoT network service providers

First 3 steps:

  • identify cities with outdated conventional street light infrastructure
  • present to them the ROI case for adopting LED-based lighting connected by a smart network that allows for control of light output, saves annual energy consumption, and provides real-time communication of functionality for ease of maintenance
  • seek out local energy utility that shares a similar vision for smart energy-saving street lighting solutions to partner with


Chicago Takes Smart Lighting Lead

The Business Case For Smart Street Lights 

Off-grid devices create drinking water

  1. Sustainability Problem: Water & Health
  2. Technology to address water-crisis: 
    • A device that converts sunlight (or other source of heat) into water and does not require high moisture nor electricity, becomes a solution for arid areas where many poverty-stricken populations live today.
    • MIT and UC Berkeley researchers developed this technology that is able to produce 2.8 liters of water per day for every kilogram of spongelike absorber it contains.
    • Crystalline powders called metal organic frameworks (MOFs) create 3D networks of metal atoms and sticky organic compounds linking together which can bind specific gases. A kilogram of MOFs is pressed into a thin sheet of porous copper metal which is placed between a solar absorber and a condenser plate.
    • References:

3. Organizational Stakeholders: Developing countries and their governments, farmers, residents and companies living in arid and poverty-stricken areas, any private sector companies and even communities committed to achieving SDGs, NGOs, researchers working on solving similar issues.

4. The first 3 steps in deployment:

  1. Currently, this MOF is zirconium-based which costs $150 a kilogram and too expensive to be broadly distributed. But zirconium can be successfully replaced with aluminum, which is 100x cheaper. First, find funding for further research to replace device with aluminum.
  2. Once enough many prototypes are created, these can be used for a pilot project to demonstrate effectiveness.
  3. Send to areas of most need, where use can be monitored and analyzed. Provide proper training on use and maintenance of the device.
