Remote Controlled Beach Lifeguard

Issues: health, safety, mobility, public administration service

Solution: This Remote Controlled Beach Lifeguard is designed to assist beach lifeguards in their task of beach and water surveillance. It was positioned on a patrol tower and stands higher than the beach crowd to get a clear overview of the area. When employed, it flies overhead for ground patrol and serves as co-rescue equipment when swimmers, surfers, and other water sports participants are in danger. This charging patrol tower can also be installed on the back of the lifeguard’s pick-up truck. It can recharge itself at the patrol tower, as well as by solar power. When hazard happens, the lifeguard and the remote-controlled assistant will make their way to the victim’s location, and the assistant serves as a surfboard. The lifeguard can control the board to pull the victim back to the coast.

Stakeholders involved: Technology companies, Beach Police, Beach users


  1. Investors raise funds to develop the technology
  2. Manufactures make mass production
  3. Contract with beach police department to deploy this product

Monitoring Tech for Sleeping Babies

1) Safety and Health:  

  • The first few years of a baby’s life are usually the more dangerous as they need to be watched at all times to ensure that they remain healthy and safe throughout their early development. Up to this point, many parents have used devices to listen for irregular activity, however OSPICON has developed a sleep monitoring mat take baby care to the next level.

2) Technology:

  • The sleep mat is used by caregivers to monitor respiratory rates and ambient air temperature
  • Once irregular breathing is detected, such as a slowdown or sudden increase in breath count, a breath event alarm is sent directly to the baby’s parents
  • It design also emits less energy than a flashlight without external wires or cords
  • A Sleep- Mat mobile app comes free with the device and can be connected to through Bluetooth or Wi-Fi to track irregular movements as well

3) Stakeholders:

  • Hospitals
  • New Parents
  • Caregivers

4) Deployment:

  • Test out the product more thoroughly with a large sample size to fix any possible bugs in the system design
  • Work with hospitals and neonatal care centers to push for adding the devices within the institutions to develop a norm of operations
  • Develop a business care for dispersing the technology into homes after babies have left the hospital

5) Student Post: 

“The business model of Plantagon is based on retrofitting, extending existing buildings, developing new buildings and establishing a symbiotic system. The whole goal of the initiative is to reduce transportation costs and emissions.”

Block-chain for Smart Grid

1. Sustainability Problem: On an electricity grid, electrons generated from the sun, wind, or other renewable sources are indistinguishable from those generated by fossil fuels. To keep track of how much clean energy is produced, governments around the world have created systems based on tradable certificates.

Category: Energy

2. Solution:

  • When a renewable-power plant generates a unit of electricity today, a meter spits out data that gets logged in a spreadsheet. The spreadsheet is then sent to a registry provider, where the data gets entered into a new system and a certificate is created. A second set of intermediaries brokers deals between buyers and sellers of these certificates, and yet another party verifies the certificates after they are purchased.
  • Such a byzantine system racks up transaction costs, while leaving plenty of room for accounting errors that can range from honest mistakes to outright fraud. The lack of transparency also scares many people off entirely.
  • A blockchain is a shared, encrypted ledger that is maintained by a network of computers. These computers verify transactions—in the case of Bitcoin, the transfer of cryptocurrency between individual users. Each user can access the ledger, and there is no single authority.
  • Keeping track of renewable-energy certificates is one of dozens of potential applications of blockchain technology that could solve data management challenges in the electricity sector without disrupting business as usual

3. Organizational Stakeholders involved: Independent Power Producers, Utilities, Technology Companies

4. Next Steps for Deployment: 

  • Develop blockchain algorithms that can be trusted by all users
  • Train utilities and power companies in use of blockchain applications
  • Create meeting protocols for all stakeholders to confer in case of any emergencies
  • Implement on a pilot basis and test effectiveness

Stronger concrete using plastic bottles

Sustainability Problem:

Concrete is the second most widely used construction material in the world, after water. Manufacturing and transporting concrete is responsible for 4.5 percent of all man-made carbon dioxide emissions. Also, there is a huge amount of plastic that is landfilled every year.

Technology Solution:

Team of researchers at Massachusetts Institute of Technology have been working on the impact of adding bits of irradiated plastic into cement.

This technology takes plastic out of the landfill, locks it up in concrete, and also uses less cement to make the concrete, which makes fewer carbon dioxide emissions. The plastic is first blasted with gamma rays, a process which is completely harmless.

Exposing the plastic to gamma radiation alters the material’s crystalline structure to such a degree that the plastic turns stiffer, tougher, and stronger.  Presence of the gamma-ray irradiated plastic and fly ash enhanced the strength of the concrete by 15 percent. Replacing just 1.5 percent of concrete with plastic makes it stronger, and could have a significant impact. By one calculation, 1.5 percent plastic in concrete implies 0.0675 percent of the world’s carbon dioxide emissions would be slashed.

skyscrapers of the future could be built with the garbage of today

From Recycled Plastic Waste to Building Material

The buildings of the future can be built as net-zero buildings by 2050.  Buildings generate pollution in two significant ways. power use and generate waste. Residential and commercial buildings account for 70 percent of power consumed in the United States — electricity that largely comes from burning carbon-intensive coal and natural gas.  Building pollution is in the use of materials like steel and concrete, which have a sizable carbon footprint.

Conceptos Plasticos (a start up) works with local communities to  source plastics to create building blocks that are fire-resistant to construct home. The plastic building blocks will degrade around 500 years or more down the road, but for now they offer shelters for families who can’t afford other housing or are fleeing crises. During the last two years, the Conceptos Plásticos team melted and molded 300 tons of plastic into building blocks for the construction of eco-homes in rural areas impacted by the internal conflict, such as a temporary shelter in Guapí, Cauca, for 42 displaced families.

New 3D Printed Tire From Biodegradable Materials


Capture d’écran 2017-11-25 à 12.59.13.png

Area : Waste, Energy


75% of tires are made of petroleum (needed for the production of the rubber used). At the end of the products’ life most of them end up in landfills .

Michelin, thanks to a new concept, 3D printed a new kind of tire. The tires are made out of molasse (sugar paste), then turned into ethanol which is used to produce rubber replacing petroleum. Since the tire is only made of natural sources (molasse, bamboo,…), the tire is fully biodegradable.  Although, thanks to the new design of the tires, their useful life should be greatly extended. Indeed, instead of changing tires when a problem arises, the new Vision tire can be modified with a 3D printer.


Stakeholders: Car manufacturers / City officials / Car owners


  • Michelin needs to research markets to find countries/ citis which are early adopters of new technologies;
  • They need to contact the government of this country/city to run some test in the city and have approval of their technology being used
  • They need to find car manufacturers that are also early adopters to pilot their technology

Other article comment: The tiles are also gathering data that can be used for better understanding pedestrians habits and crowd flows . This type of information is useful to commerces but also for cities.



Turning Smog into Diamonds

Screen Shot 2017-11-24 at 11.52.05Sustainability issue: Energy, Emissions, Health

Beijing has a major air pollution problem due to the intense industrial activities that rely on the burning of coal. These emissions lead to a perpetual smog problem (32% of smog is carbon) and lead to thousands of premature deaths every year.


  • The Smoke Free Project was founded by Dutch designer, Daan Roosegarde. The project includes two phases.
  • The first was to build a 7-meter tower that sucks in polluted air like smog and cleans it at a nano-level. More specifically, the tower uses carbon from smog particle and cleans this air before releasing it back out clean. Already installed in various parts of Beijing, the technology has proved to make the air in those areas 70-75% cleaner.
  • The second is for the tower to capture smog and transform it into diamonds. Under 30 minutes of pressure, the air can be compressed into diamonds. The diamonds would be sold to support the development and buildin gof more Smoke Free towers.
