I rarely stay up late to watch serious TV. However, this announcement, three years in the making, was something that I just couldn’t miss.
At Close Comfort, we sincerely congratulate the Global Cooling Prize 2021 winners along with all the judges and participating teams! Everyone involved in the Prize helped develop new green technologies that can cool people around the world without warming or harming our planet.
I am so thankful I don’t have to work all the time in an air-conditioned office building. Especially since Covid-19, our entire Close Comfort team works part of the time at home. We’re happier and feel healthier too.
Of course, I have a Close Comfort personal air conditioner with me. Our team members each have at least one at home as well.
Lee Kuan Yew, honoured as Singapore’s founding father, loved to tell everyone how air conditioning enabled today’s Singapore by providing a comfortable working and sleeping environment. However, there’s a dark side that comes with 20th-century air conditioning systems.
It is well established that people who live most of the time in constant temperature air-conditioned buildings lose their natural thermal acclimatization. As a result, they only feel comfortable at about 23 °C.
Recently I hailed a Singapore cab and climbed into the shiny black refrigerator on wheels, feeling so glad I remembered to bring a cardigan tied around my shoulders. The driver exclaimed, “Ah, it’s so hot today, la!”
“What’s the temperature?” I asked.
“33, it’s really hot, la”.
“But, yesterday it was 32”.
“Yeah, 33, it’s so hot today, la!”
It’s summer (but it’s not me in the photo): the magnetic needle inside my old-fashioned max-min mercury thermometer shows the temperature on my veranda reached 47°C recently. Close Comfort, an old PC8 model made in 2015 improved with the latest compact focus enhancer. It sits at the end of my bed each night and my Igloo tent is in the wardrobe should I need it. I move it to my study if I’m working from home.
As the inventor, it’s nice to be able to tell you that I use it practically all the time I need cooling.
It’s not just that I invented it. Or the knowledge that even one small tree absorbs more CO2 than is created at the power station by the electricity that it uses. Even less CO2 with solar electricity.
I have even noticed that I adapt to the heat more easily when using Close Comfort, so I don’t have use it all the time. There is evidence emerging from physiological studies that might support this perception. It’s good because my wife uses it too in her study: the kitchen where she just has to reach across to make herself cups of tea.
Recent reports have highlighted Australia’s declining results in PISA testing of maths, science and reading capabilities of children. Some in particular have drawn attention to Australia’s relatively weak performance compared with China and Singapore. I am unsure what this means. Should we invest more in maths and science education?
The Singaporean government is making it harder for foreigners to work there. International company people I meet in Singapore complain that young Singaporeans cannot perform as well as foreigners and demand too much pay, and the government is trying to force companies to employ more locals.

“The Making of an Expert Engineer” was officially launched in Islamabad at the Serena Hotel on January 7th before a gathering of 120 engineers, engineering faculty, aspiring engineers, and friends. The Hon. Ms. Marvi Memon, Minister Chair of Benezir Bhutto Income Support Fund spoke about the potential impact of the research on the poorest 5.8 million people in Pakistan served by the fund. Lieutenant General (R) Syed Shujaat Hussein, former rector of National University of Science and Technology presided at the launch.
The event was sponsored by Close Comfort Air Conditioning
James Trevelyan speaking about the book – transcript of speech appears below.
In my last piece I pointed out some of the challenges for engineers in Pakistan. Yet each of those challenges is an opportunity for any engineer who is prepared to take advantage of them. Yes, water and power are far too expensive. However, reliably supplying water and power at a lower cost represents a huge commercial opportunity because ordinary people will happily pay for a high quality service that provides real economic value over the alternatives. Given that water is the equivalent of US$50-$150 per tonne today, supplying safe drinking water at $10 per tonne is a huge improvement.
Here’s an example, my own personal invention, mentioned in the book (Ch13). Air conditioning is unaffordable for the vast majority of Pakistan people because most Pakistan buildings are not insulated. Conventional air conditioning consumes large amounts of electricity. Too many people are using conventional air conditioners, leading to electricity load shedding. Continuous air conditioning requires a generator and the electricity cost (with fuel) for a typical room air conditioner is about 20,000 Rs or US$190 for one month.
Take a look at www.closecomfort.com.
This technology can provide similar comfort, running continuously through load shedding on a UPS, for about 1,200 Rs or US$12 monthly electricity cost which is much more affordable. The first production units will be on sale in Islamabad and Lahore in a couple of months time.
Challenges like climate change also represent a huge opportunity for engineers. Engineers can do more than almost any other occupational group, and can earn high rewards from grateful people at the same time.
Some of you may have wondered why there has been a little gap in my blog posts. I have been pre-occupied with visits to several countries.
My other major project, Close Comfort has developed very quickly with keen anticipation particularly in Pakistan where electricity supplies are subject to frequent interruptions due to load shedding. Pakistan’s electricity grid is struggling to keep up with demand for air conditioning, and I hope to be able to offer a sustainable solution, as explained in Chapter 13 of the book. Continue reading
