1) Sustainability Problem: In today’s fast moving and resource-constrained world cities are facing challenges becoming smarter and be more efficient. Singapore Government is aiming for to become a first Smart Nation by 2020 which means people are empowered by technology to lead meaningful and fulfilled lives.
2)Technology Summary: The new Government Technology Agency (GovTech) was created to advance engineering support to smart nation developments and restore old e-government services. GovTech has lined up several new projects – including a digital vault of citizens data for the auto-filling of banking forms and an autonomous wheelchair prototype – to drive digital transformation in the public sector.
-Lined up several new projects – a digital vault of citizens’ personal data for the auto-filling of banking forms and an autonomous wheelchair prototype – to drive digital transformation in the public sector. Identified following five key domains that will have a significant impact on the citizen and society, and in which digital technology can have a needle moving impact:
Public-Private People’s Partnership is the key to successful deployment of the
– Educate citizens and visitors to use data (Technological literacy)
– Build a community and infrastructure
– Constant update and improvement
Water contamination is a great issue in many industrialized cities. This is especially clear in many Asian countries where the rivers are polluted from their numerous electronic recycling factories.
Perry Alagappan from Texas has designed a filter that will be able to filter 99% of heavy metals from water using graphene nanotubes. After use, the filter can be rinsed with a vinegar mix and the residue will be pure metal that can be used to produce products like cell phones etc.
Utilizing this technology in contaminated rivers and lakes in less developed countries could be very beneficial. It would help make the water cleaner, improving the overall health of the population.
Furthermore, this will provide a more sustainable way to produce new metal products. This could in turn make products like cell phones more affordable for the population.
Cell phone manufacturers
Provide proper education and detailed information about the product
Convince the government to invest in the product
Create efficient residue subtracting procedures

“This is an interesting idea in theory. It does raise a couple of questions about the implementation and practicalities, though. How will it harvest and store the energy, and how long will the charge last? Will they be able to make the paint 100% explosion safe? Because whenever hydrogen and oxygen directly interact there will be an explosion unless proper precautions are taken. I could not see anything about these issues in the article.
However, if these things are sorted and made fool-proof, this could be an amazing opportunity for houses to start creating their own fuel source. In turn, this paint could even be used on ships sailing long distances to make the journey more energy efficient, as ships are known to be a massively polluting.”
By 2050 it is expected that worlds population will exceed 9 billion. Thus the demand for food, water and energy will increase rapidly. We need to find more sustainable and environmentally friendly ways to meet this demand without increasing the strain on natural resources. The problem this technology promising future is on food step of FEW (food-energy-water) nexus.
Nanotechnology, which is basically ultra-small partials promises evaluation of precision agriculture in which farmers can control their usage of water, fertilizer and other inputs, thus reduce their waste which leads more sustainable agriculture.
For example, scientists right now researching on nanofertilizer which can be applied to plants by spraying onto their leaves. Studies suggests that such fertilizing method is especially beneficial for environment as fertilizer doesn’t come in contact with soil. On the other hand using typical fertilizer by spreading on field or mixing with irrigation water results excess nitrogen and phosphorus in soil which later can form chemical bonds with other elements and become unavailable for plants to be emitted by their roots. Eventually rain washes the nitrogen and phosphorus into rivers where it can cause pollution problems.
Use nanofertilizer instead of traditional one. You will be using much more less while getting the same or even more benefit without causing waste.
