Solar Paint

Sustainability Problem: Mass adoption of Clean Energy Alternative

It took 60 years (1840-1900) for coal to rise from supplying 5% of global energy to 50%, dethroning wood. Oil took another 50 years (1915-1965) to beat coal, rising from 5% to 40% and more recently from 1930 to 1985, Natural Gas rose from 5% to 25% of global energy supply. Given how long these transitions take, it is important to invent, develop and market technologies in clean energy for mass adoption – considering the pace at which the world is grappling to avert catastrophic climate change.

Solution: A team of researchers from Royal Melbourne Institute of Technology (RMIT) has developed a paint that can be used to generate clean energy.

  • They developed a new compound that sucks water vapor from the air – much like those humidity-absorbing packets of silica gel one can find in many consumer products. But unlike silica, the new material (synthetic molybdenum-sulphide) also acts as a semiconductor and water-splitting catalyst, meaning that it takes water molecules and separates them into oxygen and hydrogen, a clean fuel source.
  • The compound is made more effective when mixed with titanium oxide, a white pigment often found in house paint, which makes it easily applicable to a wide range of buildings – converting a brick wall into energy harvesting and fuel producing real estate.
  • This paint is likely to be effective in a variety of climates, from damp environments to hot and dry ones near large bodies of water.
  • It can be used to cover areas that wouldn’t get enough sunlight to justify the placement of solar panels, maximizing the solar output. With this paint any surface can be painted — a fence, a garage, or a doghouse and transformed into an energy-producing structure.

Stakeholders: Policy makers (Green Building Codes), Real Estate Contractors, Paint Manufacturers and typically any home/office owner.

Deployment: Before the paint gets commercially viable in next five years:

  • Paint manufacturers will have to collaborate with researchers to understand the technology and start aligning their manufacturing lines
  • Policy plays a significant role in any city dynamics – effort should begin to include such paint in any new building codes including retrofit codes
  • Awareness – researchers, paint industry (upstream and downstream) and government agencies should create awareness among residential and commercial building owners – not an expensive paint to use as an alternative, generates clean and cheap energy, an easy to use – mass adoption solution!


Connecting the World Through LoRa


  1. Sustainability Problem: Energy, Water, Waste, Civic Engagement, Safety and Health
  2. Technology: Semtech LoRa technology is a wireless, silicon microchip with long-range and low-power features for Internet of Things (IoT) operating under the LoRaWAN protocol developed by the LoRa Alliance – an open, non-profit organization. Through the LoRaWAN standards-based approach to building a LPWAN (low-power wide area network), quick public or private IoT networks can be accessed through the creation of gateways with end-devices such as LoRa, that are bi-directionally secure, mobile, and localized. These chips work through a spread-spectrum strategy to transmit at a variety of frequencies and data rates, connecting to other chips to create nodes which are then connected to gateways. These chips can be added to any device for connectivity to address issues such as water, energy and agricultural monitoring, as well as home security and hazard detection.
  3. Stakeholders:
    • Government for smart city development and community needs.
    • Industrial companies and their investors and employees that can benefit from monitoring carbon emissions, water/energy usage and waste management in order to cut spending, increase productivity and contribute to sustainability efforts.
    • Anything from schools, fleet and asset management, healthcare, to retail.
    • Households with children or elderly that are worried about safety.
  4. First 3 steps in deployment: 
    1. LoRa microchips are already on the market but marketing efforts should be increased for companies and cities to adopt this platform, in order to increase engagement of data collection for sustainability.
    2. Be strategic in deployment, ensure modernized network and management tools for non-stop information flow.
    3. With the microchips already in place, networks assessments to guarantee accuracy and security in case of cyber-attacks.

Geothermal Earth Tubes

Geothermal Earth Tubes Shown on the Right

The Problem
A lot of energy is wasted in office buildings after hours to try to keep the temperature in the building at an optimum temperature especially just before workers enter in the morning. Using energy during the night is wasteful and cooling and heating units produce GHGs that are harmful to the climate.

Technology: Geothermal Earth Tubes
The technology takes advantage of the difference in temperature between the ground and air. In winter, the ground is typically warmer than the air and the opposite is true for the summer. Since these tubes are in contact with the ground, they acquire the same temperature. During a cold night, cold air is sucked into these tubes and it travels through the ground, it slowly absorbs heat from the tube and ground and finally, the tube delivers the air to the building and provides heat, as well as fresh air and circulation. This technology does require maintenance to remove dust accumulated from outside. Also, monitoring technology is needed to control temperature levels and flow.

Cooling Air in the Summer

Residents and companies in areas where a constant need for heating or cooling is present. Manufacturers of sensors used, construction companies as well as concrete suppliers. Electricity provider who might see their revenues fall.

Next Steps
Market this new technology as futuristic and taking advantage of natural phenomenas that promote reduction of GHG emissions by humans. Promote use of earth tubes with construction companies to utilize time efficiency with installation process (These can easily be installed while construction in place).

Community-based parking

1) Sustainability Problem:

Persistent inefficiency as drivers seeking parking can not be matched with available supply.
However, ICT-based systems connecting users, vehicles (V2X) and infrastructure can increase transportation system efficiency. In this particular case, employing the automated parking sensors on vehicles traversing the city is an innovative way to use the fleet to collect real-time data about available spaces. This obviates the need for parking detection hardware on street lamps or embedded in the pavement.

Blockchain Technology for Food Security

Sustainability problem:

Every year, hundreds of thousands of deaths are attributed to food contamination. Because a supply chain is extremely complex, it is lengthy and costly to identify the source of contamination, which leads to illness, food waste and costly financial losses.

Food traceability is, therefore, a crucial challenge to be tackled in working towards sustainable development and specifically SGD goal #2 – end hunger, achieve food security and improved nutrition, and promote sustainable agriculture.


IBM has partnered with global companies Nestle, Unilever and Tyson Foods to integrate its block chain technology platform into their supply chains.

Blockchain technology allows transactions to be permanently recorded and easily traced within a business network. Groups of transactions are blocked together and, what IBM calls a ‘fingerprint’ of that block is then added to the next block. In addition, since no transaction can be altered without being recorded by the entire network, the data is secure and accurate.

In the context of food supply chain, Blockchain would allow to quickly and accurately follow the origin of goods. When cases of contamination arise, it would also allow to identify with certainty the origin of contaminated foods and track them while reducing other food wastes.
