Summary Reader Response - Draft #2

The article “Go-Ahead Singapore carries out 6-month trial of public buses with solar panels,” (Kok, 2021) is about the bus operator, Go-Ahead Singapore, experimenting with solar panels on the backs of 2 A22 buses to use solar energy to power the battery as opposed to fuel to combat carbon emissions. 

The trial was reported to last 6 months, from March to September, in Pasir Ris with solar panels of 1.6mm thickness which were also malleable and toughened to be shatter-resistant. 

The panels are stated to be capable of supplying 1000 watts of energy to the battery while being as light as 20kg. The battery is used for ignition and to supply power when the engine is turned off and was previously dependent on the bus' alternator. The presence of panels was cited to reduce the load on the bus engines, and based on data from Southampton in the UK, save 4000 litres of diesel and reduce 3.7 tonnes of carbon emissions annually. 

GAS managing director Thompson was stated being hopeful that the panels could potentially be fitted on more gas and electric buses based on the calculated savings. He was quoted thanking LTA for their collaborative efforts and their support in loaning the buses for this experiment.

In summary, this trial is expected to be successful and expand, given how the cost of the trial itself could be recuperated within just four years.

The trial with solar panels should prove to be successful, as it is a cheaper, consistent and environment-friendly alternative to fuel with little to no fallbacks.

Critical Reflection

My personal goals set for this module was to improve my vocabulary and feel comfortable presenting so that I could be more interactive with the audience. Looking back I am gratified in seeing some obvious improvements with what I set out to achieve. Through this module, I’ve learnt to embrace critical thinking and apply it to other modules, the essence of communication through the 7C’s of communication, summarising and paraphrasing with accurate citations and developed my oral and writing skills. I this reflection, I’ll be focusing specifically on oral development skills and my project work as it was my key focus for this module.   In the past, I’ve heavily relied on scripts, in the belief that a good script done with proper homework could make or break a presentation. The scripts were also prepared with the assumptions that the audience have no prior knowledge of the topic. This made my presentation sound more of a lecture with focus being on the background information. I would l...

Self-Introduction Letter [EDITED]

Dear Professor Blackstone, My name is Lakshmanan Thiyagu, and I’m writing to introduce myself as a student attending your effective communication module. I graduated from Singapore Polytechnic with a diploma in mechanical engineering. I also have experience working as service technician in Chloride Batteries (CB) after obtaining my diploma. Over the year I spent in CB, I had the opportunity to assemble industrial battery chargers from scratch. It was fascinating to interact with individual parts by hand, after only reading about them in textbooks. It was also gratifying to see my efforts take shape in real time. This experience persuaded me to continue pursuing a degree in mechanical engineering.  My personal strength in communication is making others feel heard in a conversation. This stems from struggling to communicate or speak out my thoughts, fear of being shot down before I finally found my voice. Hence, I’m understanding in how others feel and help them to speak up more. ...
