The White Hat Environmental Sustainability NewsletterArchived Newsletter - 30th April 2009Contents
Why this newsletter?There is already a ton of stuff out there about environmental sustainability, so why should White Hat add more to this growing pile? Well I suppose our reasons were tied up with the thoughts of a great philosopher of recent years who told us there were:
I’m sure that you will help us fill it in. But we might be so bold as to add one further category to the previous four suggested by the great philosopher.
Well no we won’t actually but we will ask numbers of questions and you can give us some of the answers and in the end we might all know a little more. ElectricityElectricity. Great stuff! You flick a switch and something happens. It replaced all sorts of dirty, smelly, inconvenient, inefficient, clumsy, polluting contraptions that were part of the home and the workplace in the 19th century. But it has its problems – and opportunities. We thought we might us this newsletter to discuss some aspects of electricity. In future newsletters we will discuss:
Known Unknowns - long life light bulbsThis section of the newsletter has been moved to The White Hat Guide to Recycling & Downcycling. Storage of ElectricityThis section of the newsletter has been moved to The White Hat Guide to Electricity & Environmental Sustainability. Solar EnergyThis section of the newsletter has been moved to The White Hat Guide to Electricity & Environmental Sustainability. Bicycles & energy storageWhen it comes to converting human energy into propulsion, the bicycle is possible the most efficient machine invented by man – part of the time. Then when it comes to storing the unused energy its efficiency is 0%. Electric and hybrid-electric vehicles generally use ‘regenerative braking’ to store energy for later use. An electric tram or train will usually pump the energy back into the overhead wires while smaller electric transport right down to the personal transporter of a Segway which is smaller than a bicycle will store the energy in a battery. Now the storage process is highly inefficient but seems better than the option of not storing it at all. The standard bicycle throws away its braking energy as heat. If you live at the top of a hill and ride to work, none of that additional energy that was thrown away can be used to help you back up the hill at the end of the day and it is this inefficiency that rules the bicycle out for many people for numbers of everyday work and domestic tasks. The bicycles of a generation ago powered their lights with a ‘dynamo’ but even this has gone and cyclists use battery powered lights. Maybe if the wasted energy of the bicycle can’t be re-used for propulsion it could be used to recharge batteries for the mobile phone. The technology is there. Recently at Federation Square there was a worthwhile awareness-raising exercise whereby a set of 20-odd bicycles were connected to generators. Over the week, workplace teams were invited to come and compete against each other and in the end the energy would be used to power a one hour popular music concert with its amplification and lighting. What I found interesting was that after a week of sweat and exertion I believe the one hour concert still had an energy deficit. Maybe when our parents and grandparents sat in their turtle neck sweaters in coffee shops listening to acoustic music by candlelight they were doing more for environmental sustainability than those of us who enjoy going to high energy rock concerts. You can find more information on alternative energy vehicles and bicycle power in a previous White Hat Inventions Newsletter. BatteriesThis section of the newsletter has been moved to The White Hat Guide to Recycling & Downcycling. What if everyone did it?I had an elderly relative in Sydney who had various sources of ‘free’ energy. Some of them were even legal. For instance, clamped between the troughs she had a small mechanical spin-dryer which operated by water power. You attached the hose to the tap and the mechanism focused a strong flow of water onto the blades underneath causing the dryer to run a speed with sufficient speed to impress a seven year old child. Water cost next to nothing because there was a single water rate charge related to the value of your property rather than the amount used. And she was getting the power to run the spin-dryer for free.”If that power is there for free, how come everyone doesn’t use it?” I asked. (I knew not to ask such things when her gasfitter nephew came around to do strange things with the gas meter, but in this case it seemed a reasonable question.) “Because they’re not as smart as your old aunty!” Through my childhood I was vaguely troubled by this. There were plenty of people out there as smart as my old aunty – not as cunning maybe, but certainly as smart. It wasn’t until I was older that I realised the problem was the ‘what if everyone did it factor’ or what scientists, mathematicians and engineers call ‘scalability’. The water pressure was being provided by a number of pumping stations and if everyone started drawing energy out of the system the flow would stop to a dribble and you have to put in larger pumping stations and heavier pipes which all have to be paid for somehow so that people can get ‘free’ energy. In fact, before long you’ve produced the ‘Hydraulic Service Power Company’. More about that in a coming newsletter. When I attend sustainability and lifestyle fairs I see a number of products and services that don’t pass the ‘what if everyone did it’ test. When I ask about scalability a puzzled look usually comes over the face of the sales person but the response usually roughly translates as “that’s not going to happen because they’re not as smart as your old aunty.” Meanwhile I sometimes wonder about ‘renewable’ energies such as solar, wind, tidal, wave and hot rocks. We are told they are renewable and have no side effects. I still want to ask the ‘what if everyone did it?’ question. It seems likely they would have far less side effects than current methods but it seems worth investigating and planning for the side effects rather than simply chanting the mantra that they are endlessly renewable and cause no environmental damage. Recycling & DowncyclingThis section of the newsletter has been moved to The White Hat Guide to Recycling & Downcycling. Use Energy, Get Rich and Save the PlanetYou might find the article in The New York Times with the above title a useful conversation starter next time a group of you talking about the environment. Electricity - action at a distanceThis section of the newsletter has been moved to The White Hat Guide to Electricity & Environmental Sustainability. Is this newsletter green?As we stated in a newsletter six years ago: “We live in a wide brown land on the driest continent on earth. We have always regarded the adopting of the term "green" to indicate environmentally responsible as particularly mindless. In many parts of Australia where you see large areas of green, you know that it is probably the result of unsustainable practices.” So, no, you won’t find us using the word ‘green’ to indicate environmentally responsible. Nor are we likely to discard our plain shopping bags for ones that have had their carbon footprint increased by using a (often toxic) green dye. It does mean that we are often rejected for not using the prescribed tribal language or tribal markings but that is part of the price you pay for being Independent and (occasionally) Irreverent. Great Moments in Marketing
Drying clothesOn winter days when the clothes line is not an option we hang bulky items like towels to drip and dry over the bath before we leave home in the morning. In the evening they are still damp to the touch but only take a fraction of the time to freshen up in the dryer. ComputersComputers are one of the inventions of recent times which have enormous potential to save lots of energy. Let’s take an example. Each week we send out a newsletter to 10,000 people. It’s ostensibly about what’s on in Melbourne but it ranges far and wide and about 10% of our subscribers are from overseas. A generation ago that would have involved chopping down numbers of trees, turning them into paper (very greedy on water) printing (with possibly a lead-based ink), placing in envelopes and creating lots of greenhouse gases by having to transport those physical newsletters to all parts of the globe. We could possibly improve things slightly by using downcycled paper. Now, we just press a button and they are sent electronically. That doesn’t mean there are no carbon overheads, but they are dramatically fewer. However computers use electricity and some are more efficient than others. Currently at White Hat we use a laptop computer because its energy use is much lower than the equivalent desktop PC. However a laptop requires a different style of construction and may well involve more polluting materials. Quite frankly, we don’t know. Reliable sources of this sort of information (as distinct from marketing claims) are very hard to track down. If any of you can help, please let us know. Are we simply saving some energy now at the expense of the whole-of-life environmental impact of using a laptop rather then a desktop PC? Wasted EnergyThis section of the newsletter has been moved to The White Hat Guide to Electricity & Environmental Sustainability. From the White Hat InboxWe had the following interchange of text messages:
Death of an EnvironmentalistRichard Pratt died this week. When his reputation was at its peak we referred to him as the ‘Recycling King’. Then he ran into some problems regarding his business practices so we called him the ‘Packaging Magnate’. However that should not blind us to the fact that he was prepared to stump up many millions of his own dollars in an attempt to save the Murray-Darling but in the end had to give up because most politicians couldn’t see what was in it for them at the time. However, he is also worth remembering as a pioneer of highly efficient energy use in factories. In the Visy recycling plants great attention was given to how any ‘waste’ energy produced by one process could be used to assist some other process. The result was that some of the best plants were virtually self-sufficient in energy. We don’t pretend to know the details and rights and wrongs of your business practices but for your pioneering work in environmental issues we say – Thank You Dick.

Making a ChangeHere at White Hat we try to do our bit to make changes that will benefit the environment. We do this by however imperfectly, attempting make changes at the personal level, attempting to generate change at the community level and at the political level. It’s not something we would describe ourselves as being ‘passionate’ about – there are other things we are passionate about. It’s just that we live in the 21st century and its one of the things you have to do. We realise we have numbers of loyal readers who are in significant decision making positions and for that reason we will keep asking the questions and attempting to give some useful answers from time to time. We don’t know how successful we’ll be, but we will attempt to encourage readers to be:
If you don’t find our approach useful, that’s fine – unsubscribe – there are tons of alternatives out there and you are sure to find one better suited to yourself. If you do find it useful, tell a friend. The White Hat Environment QuizElectricity & heat
