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

REGN – Rainfall Energy Harvester

Screen Shot 2017-11-02 at 11.13.22 AMREGN is a rainfall energy harvester taking the guise of a simple connector insert between rain gutter pipelines. Rainfall is an often overlooked source of renewable energy due to its unpredictable nature.

The  REGN is designed to involve:
i. The efficient capture of rainfall
ii. Utilisation of rainfall (a source of natural renewable energy)
iii. Regions prone to rainy seasons?
Screen Shot 2017-11-02 at 11.13.27 AM
Sustainability problem: Energy, Rainwater, efficiency


  1. The insert utilizes the motion of rainwater diverted from roofing structures along gutter pipelines to generate electricity by electromagnetic induction as magnets located on a spindle within a funnel column is spun on a plane coincident to copper coils leading to an external output connector.
  2. Fluid flow was designed around a planar cross-section, the design is easily adapted to American (rectangular) and Commonwealth (circular) pipeline standards.
  3. The exterior of the device is specified to be made from materials able to provide ample shielding from tropical heat and UV radiation.
  4. Surfaces in contact with acidified fluid/moisture (due to contamination from airborne or surface pollutants) would be specified with materials inherently able or treated to resist corrosion).
  5. REGN’s compact frame allows for practical use of magnetic levitation
  6. REGN modules are ideally installed among gutter pipelines in dense urban settings.

Hybrid Wind Power Generating & Fish Farming System


Screen Shot 2017-10-19 at 1.42.17 PM

Sustainability: Energy, Wind power, small-scale fishers

Small-scale fishers are concerned about offshore wind farms but the scale and speed of wind farm development offshore might mean that the situation is likely to change in the near future. The primary concern for small-scale fishers is the potential loss of access to fishing grounds within turbine zones. Infrastructure cost for the conventional floating wind turbine is a tremendous cost. Hybrid Wind Power Generating and Fish Farming System resolve conflicts between wind energy companies and small-scale fishers, leading both parties to collaboration.

Screen Shot 2017-10-19 at 1.42.31 PM


  • Base: Vertical axis wind turbine (VAWT)
    • VAWT doesn’t have complex steering systems
    • Lower center gravity
  • Fish cage structure with a small waterplane area twin-hull feature
    • More stable system against ocean wave impact


  • Fishman
  • Small-scale fishing companies
  • Local government
  • Wind energy company
  • Turbine Manufacturer
  • Turbine  Installer

Steps to deploy this technology:

  • Engage small-scale fish companies, governments, and energy companies
  • Wind energy companies can rent fish farming zones from small-scale fishers to set up these hybrid systems
  • Hire and train local coastal fishers to work as wind turbine maintenance engineers
  • Local government or NGOs can fund small-scale fishing companies
  • Encourage Fishman to grow into an energy company and run both a wind energy and a fish farming business

Nanotechnology Brings Clean Water to Rural Pool

The sustainability problem: Water Sustainability.

One of the modern technologies that can help in the addressing of water sustainability problem is nanotechnology. According to a report by the World Health Organizations over 1.6 million people die each year due to lack of clean and safe drinking water. The nanotechnology removes microbes, bacteria, and other matter from water meant for human use particularly drinking by use of composite nanoparticles that emit silver ions which destroy the water contaminants. An interesting thing is that this technology is highly scalable in terms of cost, with the cost of getting purified water by this technology going for as low as only $2.5.

Solar-powered Pipe desalinizes drinking water

#watersustainability #Water

Screen Shot 2017-09-21 at 11.25.30 AM

Clean drinking water is a big challenge for many people across the globe. Despite there being many efforts to invent technologies that can help achieve clean drinking water, another challenge of energy needed to run some of these purification equipment sets in. A new technology currently being used in the California is a solar-powered pipe that can generate its own power and use this power to process water for drinking. It is a technology that if properly developed can go a long way toward contributing water sustainability on a global scale.

Screen Shot 2017-09-21 at 11.25.38 AM

  • The solar-powered plant deploys electromagnetic desalination to provide clean drinking water.
  • The system also contains a system with a mechanism that allows for filtration of the desalinated brine through onboard thermal baths before the brine can be reintroduced into the ocean.
  • The system has solar panels that provide power to pump seawater through an electromagnetic filtration process.
  • The technology leads to the design of equipment that can generate 10,000 MWh per year, the power that will then be used to produce 4.5 billion liters or 1.5 billion gallons of pure and safe drinking water. For most drought-prone regions, the Pipe represents a change in the future of drinking water as it saves energy by generating its own solar power than requiring external sources of power.
