Energy Savers Cooling a Warming World

You probably know that I now spend most of my time running our little technology startup company Close Comfort.   We recently passed a significant milestone with over 1000 of our energy-saving air conditioners sold to happy customers.

It all started with my marriage to wonderful wife and partner Samina Yasmeen.  Living with her Pakistan family brought summer reality.

Two billion people South Asia dread the summer. Shimmering heat starts in March and April and stifling sweaty nights last into November.  Listless days follow nights of fitful sleep at 40C under noisy fans. A tiny privileged elite run energy guzzling split air conditioners, crippling electricity grids.

Load shedding, a novelty in Australia, is routine across south Asia and Africa: power is on and off every hour or two.  Batteries keep fans and LED lights on but the unit electricity cost soars.

Sustainable relief from heat and humidity is now in sight thanks to our energy-saving air conditioning technology.   It’s a great thrill that our air conditioners are now in 5 countries, albeit with small-scale marketing campaigns.

Guide for Value Creation in the Engineering Enterprise (Updated March 4, 2018)

  • Engineers’ remuneration and recognition is strongly related to the value they create – a well-supporting finding in economics.
  • Our research shows that engineers today know little about value creation, and what little they do know does not align well with investors’ ideas.
  • We conclude therefore that engineers will be paid less than they think they are worth (which agrees with survey findings) and second, there is plenty of potential to improve engineers’ remuneration and recognition if they take the time to learn how to create value.

The Great Artificial Intelligence Scam (Again)

{A longer version of this post appeared in the Australian Financial Review on August 18th under the title “When robots learn to lie, then we worry about AI“.}

Great claims are being made for artificial intelligence these days: AI.

Amazon’s Alexa, Google’s assistant, Apple’s Siri: these are all claimed as examples of AI.  Yet speech recognition is hardly new: we have seen steady improvements in software like Dragon for 20 years.

We have seen claims that AI with new breakthroughs like ‘deep learning’ could displace 2 million or more Australian workers from their jobs by 2030.

I was fortunate to discuss artificial intelligence with a philosopher, Julius Kovesi, in the 1970s as I led the team that eventually developed sheep shearing robots.  With great insight, he argued that robots, in essence, were built on similar principles to common toilet cisterns and were nothing more than simple automatons.  “Show me a robot that deliberately tells you a lie to manipulate your behaviour, and then I will accept you have artificial intelligence!” he exclaimed.

That’s the last thing we wanted in a sheep shearing robot, of course.

Engineering Value Creation

Before reading this, please see the post of December 7, 2017, where I have released a comprehensive guide for engineers, students and educators on value creation in engineering enterprises…..

In my last post, I wrote a brief explanation about value and value creation, noting that “value” has many different meanings.

In this post I will summarize what Bill Williams and I think is a new theory of engineering value creation, the subject of my address to the International Conference on Engineering Education Research (iCEER 2016) in Sydney on November 24.

Trump needs engineers who understand value

Americans have voted, and most of us were surprised.

I just watched a CNN interview with a former factory worker who voted for Trump. “We need lots of small factories with 200-300 people making things, employing Americans.”

Trump can’t deliver that.

Only engineers can make that happen, engineers who know how to create sufficient value to attract investors.

Bill Williams and I have recently discovered that many engineers know little if anything about creating value for investors.  Supported by students, we interviewed practicing engineers and found that, for example, most associate the word “value” with a number in a spreadsheet.

We also discovered little in the business and engineering research literature that can help.

A small number of “expert engineers” have worked it out for themselves, without necessarily being able to explain it in simple terms.  They are well rewarded by their clients and employers because they create so much value for their enterprises.

We have recently written a detailed explanation which, we think, explains how these experts create value, and we hope this makes sense for many more engineers who could just make enough difference, everywhere.  Not only to help frustrated Americans.  Engineers who know how to create value effectively could transform our world and eliminate poverty.

Since the industrial revolution, we have all come a long way, but most of us know we cannot sustain our civilization into the future without making some big changes.  We engineers have to lead these changes, but we need huge resources from everyone else to make it happen.  And that requires insights into value creation that elude the vast majority of engineers right now.

In coming posts I will do my best to explain the fundamental ideas that have emerged from our research and what we mean by value creation.

Why failing drinking water supplies are a catastrophe for us all

When I started writing about drinking water supply in low income countries (like India and Pakistan) I saw it primarily as an economic issue.  It was only when I read recent papers on stunting that I realized the catastrophic health and economic impacts of stunting caused by faecal contamination of drinking water supplies, now common in many parts of the world.

Stunting occurs when infants drink contaminated water causing repeated diarrhoea attacks which result in permanent damage to the intestines, restricting nutrient intake so affected children suffer from malnutrition even if they eat enough. Nearly half of all children in South Asia and other parts of the world are now affected.  So many piped water schemes provide contaminated water at the point of consumption.  The water pumped into the system may be safe to drink, but what goes into the mouth is not.

The only way to start fixing this problem is safe drinking water distribution. Obtaining and treating bulk supplies of safe drinking water is relatively inexpensive: even desalination costs only $0.50 per ton. While there are many water-scarce regions, in most there is still plenty to drink once treated.  The scarcity affects agriculture more than drinking.

Piped water supply utilities are failing in most low-income countries and few if any provide a 24/7 supply of safe water. For example, “good” utilities in South Asia provide intermittent water for 1-2 hours every 2nd day: sewerage seeps in through leaks during the “off” time contaminating the network. Many leaks result from crude attempts by engineers to enforce revenue collection by temporarily disconnecting adjacent water and sewerage pipes to recalcitrant customers. Air trapped in pipes destroys meters. A downward spiral in service quality and revenue collection forces people to stand in line to bribe tanker drivers to refill contaminated domestic tanks. Water has to be filtered and sterilized to make it safe, or supplied in 20 liter bottles at $100-150/ton.

Low trust between consumers, utilities and government undermines attempts to improve service quality. Conventional water supply technologies require trust and collaboration between diverse social actors which is much more difficult than in high income countries so the problem persists.

And for the majority of people who have no piped water, the situation is even worse. When women carry and purify water their labour is unpaid but comes at a cost: more than $30/ton across South Asia using standard value of time models.

The consequences of drinking water safety failures affect everyone: the real cost of getting just enough can exceed 10% of family income. It helps to explain stubbornly persistent poverty, stunting and malnutrition from environmental enteropathy caused by fecal contamination. The economic and health catastrophe in low-income countries affects us all.

In the next post, I will describe why so many previous attempts to solve this problem have failed and how I came to see some elegant solutions.
