Summary Draft 2

 This article “The Future”, written by Lockett William introduces a new type of batteries called lithium-sulphur and how it will shape our future.

Currently our battery choice has always been lithium-ion batteries, however they have some downsides to using it. Scientists at Drexel have been trying to find a way to allow the production of batteries to be cheaper while having more power output where they discovered lithium-sulphur which is able to solve all lithium-ion’s problem.

Firstly, lithium-sulphur batteries are cheaper to produce as the resources needed to make this battery are abundant all over the Earth, and mining for sulphur can reduce the ecological impact whereas mining for cobalt, one of lithium-ion main components is environmentally damaging.

Secondly, lithium-sulphur batteries are three times more energy dense versus lithium-ion batteries, meaning that it has a larger storage capacity, and it is much lighter.

However, the downside to using lithium-sulphur is that it has smaller charge cycle compared to its counterpart because when the battery charges and discharge, it creates polysulfides which take away some of the sulphur out of the electrode contributing to the reason for its smaller charge cycle. To solve this issue, the scientists has been doing experiment to modify the compounds in the battery’s cathode to solve the issue of its small charge cycle.

The use of lithium-sulphur batteries could change human lives as it allows a huge range of activities to go electric, allowing the emission of carbon dioxide to be much lesser which would potentially save the Earth as well.

Submission 1a: Descriptive Reflection: Self Introduction Letter

  Subject: Self Introduction Dear Mr Brad Blackstone,   My name is Justin, and I am writing to introduce myself to you as a student in your Critical Thinking and Communication (UCS) class. Some background about me is that I graduated from Singapore Polytechnic with a diploma in mechanical engineering. In the beginning, I had no idea what I liked, so I chose engineering as mathematics and physics are my strong suit. During my final year project in Polytechnic, I met with many industry leaders in the field of engineering, where they showed on the potential of engineering can do and how they are able to impact and make changes to people's life, and it successfully managed to pique my interest of engineering, hence I decided to continue my choice of engineering in university hence enrolling in this engineering program.  My weakness in communication is public speaking, as I tend to feel nervous when speaking to large crowd and in a classroom setting as well, because I am worried

Critical Reflection

Module reflection: We are constantly using critical thinking and critical reflection in our everyday lives on a subtle level. Critical thinking is a few step process that starts by describing the problem, analysing the problem and gathering information online while cross reference the information to ensure that the information gathered is a valid and true. Next is to solve for the problem and evaluate the solution proposed. The next step is the most crucial step and is linked to critical reflection, which is to reflect on what has been done, so as to ensure that we will not repeat the same mistake in the future. As mentioned earlier in my self-introduction letter, I managed to achieve the goals I set for myself for this module, which is to be more confident when speaking in a large group and writing skills. Before the actual presentation, my team and I had done numerous rehearsals in order to prepare ourself. With the feedback provided by my teammates, it enable me to experiment the ty

Importance of Communication Skills

                      “I contend that we (engineers) are undervalued because of our widespread                     inability to explain what we do to the general public (and why it is so important). It is one of the hardest goals to accomplish, to be able to boil down difficult concepts into a short and easily understood presentation or elevator pitch.” Marybeth Miceli, President, Miceli Infrastructure Consulting, USA (2011)       My take on this quote is that for engineers that are specialised in their field, whenever they must explain a topic needing their expertise, they tend to talk too in depth about it to the point where not everyone is able to understand what they are saying unless they have some background knowledge about the topic.  Thus, engineers being undervalued is due to the fact that we are unable to simplify the terms for the common people to understand as the things might be too complicated, hence usually people would be asked to explain it in layman terms
