TWC Lesson 11

Presentation week.

Group 1: Futuristic buildings.

The first group’s presentation about futuristic buildings tackled quite a number of pressing issues our planet is currently facing. It has also taught me the history of buildings and the current interesting technologies used in buildings. It was really interesting as they brought a model along to show us how their design of the futuristic building would look like. In my opinion, their model would be able to tackle a number of problems.

Rising sea levels
Global warming has caused quite a number of problems for our environment. The increased global temperature has caused huge icebergs to melt in the poles, and that is raising our seawater levels. As such, a floating/waterproof home does sound like a very feasible technology for low-lying countries that will be affected. Furthermore, evidences has shown that the increased global temperature has also caused stronger and more frequent typhoons and hurricanes to be formed. Such could cause extreme flooding and devastation to areas affected. A recent example would be hurricane haiyan that devastated Philippines.  As such, a floating house could help them reduce the damage incurred as it would be able to float amidst all the flooding and increase survival rates for those affected.

Lack of land
There has been a lack of land for residential purposes in many developed nations and cities recently. Singapore has been experiencing a lack of land for many years now as seen from our high prices for property. The fact that our HDBs are being built higher can also be seen as evidence of our land shortage. As such, living in/on the sea would greatly ease the land crunch on such developing countries as they would be able to allocate housing on the sea. Such would lead to more people being able to afford housing as the increased supply of housing would drive prices of housing down.

However, the important issue here is the price of such buildings. Would they be a novelty only available to the rich? From the presentation, it seems like the technology needed to build such a structure is pricey and is very likely unavailable to the less well-off. Underwater turbines and solar panels are all expensive structures. It is important that we do not get complacent when we complete such technology and continue to strive for and innovate ideas to drive the cost down. For example, with the extensive research done on plastic recently, could we possibly build the structure out of the cheaper plastics instead?

Group 2: Clean energy

My group was the second to present and our topic was clean energy. Due to our negative approach to presenting, we exceeded the timing pretty badly. As such, this has actually taught me that when presenting an idea to an audience, we should always try to capture their attention and allow them to participate. We should have only presented on the ideas that were interesting instead of reading word to word from our website. Throughout my research of clean energy, I have come across many interesting applications and types of hydroelectricity. Through all the research, it seems like the world already possess the technology necessary to be sustainable, but many political and social issues are preventing that from taking place.

Group 3: Nanotechnology

Nanotechnology is one of the upcoming technologies that will revolutionize the way we do things. It is exciting to know the wide variety of ways nanotechnology could be applied to. Such include

Healthcare
The group talked about how nanotechnology could be used to kill cancer cells without harming the normal cells. Such is a huge improvement from our current chemotherapy methods were all the cells within the vicinity are damaged and destroyed. Such could make cancer treatments much more tolerable as the heavy side effects such as vomiting from the chemotherapy could be avoided. Furthermore, nanorobots that can specifically target cancer cells seem like a much more efficient way of curing cancer as compared to chemotherapy where some portions of the cancerous cells may not be destroyed.

Hydrophobic nano particles
I have seen many videos that shows how such hydrophobic particles work. It really seem like magic to me the first time I saw it, on how mud water or water can just slide off cotton materials as if the surface was waxed. If anyone is interested, here's the video.




The first thing that came to my mind was how it could be applied to army equipment. Imagine spraying such a coating on my boots, field camp would be so much more bearable with dry feet! Such technology could also be used for windscreens for cars during a storm to increase visibility, or sprayed on to glasses so that they do not fog up or get wet in humid environments.

However, as prof always says, technology is easy but people are hard. There are many possible consequences of such technology and I believe we should properly assess and forecast Nanotechnology so as to be prepared and prevent any negative impacts it could bring. As I stated in one of the post below, movies often showcase the possible implications of future technologies. In movies such as GI Joe: The rise of the Cobra(2009) or The Day the earth stood still(2008), it all shows how nanotechnology has been converted into weapons capable of mass destruction. Although such movies are based on fictions, I believe such concerns does stand true. If some scientist managed to convert nanotechnology into workable weapons, the consequences would be dire.   

To conclude, the presentations gave me great insights into different technologies and has helped me broaden my knowledge base. I would give this lesson a 9/10!
