Water and Energy

So you thought that water was just good for drinking and for fish to frolic in? Not so! For a number of years there has been an incredible amount of research and development into wave power / energy as a renewable energy resource for the globe.  Here I pause [         ] and metaphorically take a sip of water *sip* before presenting the following:

Wave Energy as a Global Energy Resource

Wave energy is a renewable energy resource created by large storms hundreds of miles offshore that generate and transmit huge amounts of energy which travels great distances (via swell) and mixes with local influences (seas) to arrive at our shores.

It is a genuinely renewable energy source and distinct from tidal energy.

Wave energy is generally considered to be the most concentrated and least variable form of renewable energy. It is the high power density of wave energy that suggests it has the capacity to become the lowest cost renewable energy source.

Wave power is a relatively unknown solution as a clean energy source, yet its uninterrupted and continuous source of energy has the potential to be among the most enduring suppliers of the world’s future needs if some obstacles can be overcome.  One major problem with most wave technology is that waves have too much energy.  Britain has 35 out of the world’s nearly 130 wave energy and tidal stream device developers, which include Pelamis, Aquamarine Power and Marine Current Turbines.

The World Energy Council has estimated that approximately 2 terawatts (2 million megawatts), about double current world electricity production, could be produced from the oceans via wave power.  It is estimated that 1 million gigawatt hours of wave energy hits Australian shores annually and that 25% of the UK’s current power usage could be supplied by harvesting its wave resource.

In 2011, consistent with other industry forecasts, the UK Carbon Trust estimated that the Global Marine Energy sector could be worth US$760 billion by 2050 and could support 68,000 jobs in the British Marine energy sector alone. Industry estimates put annual marine energy revenues at nearly US$100 billion by 2025. CETO is a portable technology and through Carnegie’s 100% ownership of the technology Carnegie has full access to this untapped global market.

Wave energy has significant global potential with the USA, North & South America, Western Europe, Japan, South Africa, Australia and New Zealand among some of the best wave energy sites around the world.

Wave energy flows in the direction of wave propagation and is measured as the amount of power (in kW) contained in each linear metre of wave front. Typically energy above 20kW/m may be suitable for CETO wave farm projects.

Incroyable, no? I think so. So incredible actually that I’ve been conducting experiments with our water cooler this morning. I’ve been simulating wave power by inserting the wires from my voltmeter into the bottle, then rocking the water bottle back and forth to create waves and to see whether they generate power. All was going swimmingly well (I thought) until the bottle came adrift, water sloshed about (only a bit) and someone ratted me out to the HOD, Mrs Furthingstoke. Seems as if I’ve been banished from the water cooler area until further notice. Apparently, somebody will bring my drinking water to me.

Never mind, as soon as I get home, it’s straight into the tub, where I’ll be building up a serious rate of knots (energy) by squooshing back and forth creating ginormous waves.

It’ll take more than Mrs Furthingstoke to deter me from reaching life changing scientific breakthroughs!

The Elephant Pump

The Elephant Pump

The Elephant Pump is based on a 2000 year-old Chinese design that the CEO of The Africa Trust, Ian Thorpe, adapted to make it stronger, more durable and made and maintained using materials that are locally available in remote rural sub-Saharan African communities.

The core program of pump building in Zimbabwe has grown with 432 Elephant Pumps installed in 2012 compared to 367 in 2011.  This is now a massive program with the Elephant Pumps, managed by The Africa Trust, providing clean water for over 10% of the entire population of Zimbabwe. In addition to the core staff, it has been possible to provide contract work to over 40 other individuals during the course of the year.

The Elephant Pump was awarded the St Andrews Medal for the Environment in 2005, competing against 250 other applicants. Prince Charles, a patron for the St Andrews Medal, gave a personal recommendation towards this option of water extraction:

“Each project has had a direct and positive impact on people’s lives. While it is perhaps invidious to highlight just one of them, I believe a good example is the success of The Elephant Pump project. Based on a 2000-year-old Chinese technique for lifting water, The Elephant Pump is inexpensive, simple to make and repair and made from locally available materials which give users a greater sense of ownership. When more than a billion people live without access to clean drinking water in the world today, it is hard to imagine a better cause than this”.

Ian Thorpe then became the first person to win The St Andrews Medal for the Environment on two separate occasions when his design for the Elephant Toilet was awarded in 2008. Since winning the medal, this toilet has been introduced throughout northern and central Malawi.

Pump Minders – Key to Sustainability

It has been seen that the pumps which have been well maintained over the years are at sites where at least one key person has been trained on how to maintain the pump. Instead of simply providing general training for the whole community, The Africa Trust has recognised that it is vital to train at least two people who are likely to remain in the community. Many young men leave the rural areas in search of work. Older women are often the best people to train, as they are less likely to move away.

Once identified, 2-3 pump minders per pump receive initial training when the pump is installed with further training after 3 months, 6 months and one year. By this time, it is expected that the pump minders will be able to do all minor repairs with informal payment in kind (often in the form or food) from the others who use the pump. Spare parts for the pumps (such as washers and rope) are made from waste products and the pumps contribute to increased agricultural production, so this approach to maintenance is sustainable.

Pump minders collect a low level of community contributions once the pump is productive to pay their wages and a small part returns to The Africa Trust. This helps pay back the capital cost over five years. Millions of people in over seven thousand communities use Elephant Pumps.

BTWC – Before the Water Cooler – 19th Century

In order for us to reach the very convenient, refreshing and rather necessary plateau of the age of the Water Cooler, this is how water wended its way throughout the UK throughout the decades.

This week, we look at potable water solutions and discoveries through the 1800’s.

1808
Richard Gillespie devised a filter system for Glasgow’s Cranston Hill waterworks using a layer of sand and gravel.

1820s
Robert Thom in Scotland and James Simpson in England perfected mechanical and sand filtration at the same time.

1826
Aberdeen collected water from near the Bridge of Dee by building a tunnel alongside the river which drained off filtered water from the river bed.

1840
John Roe helped solve the problem of blocked drains by building an egg-shaped sewer.

1847
Polluting drinking water was made a criminal offence.

1847
An aqueduct and pipeline was built to bring water to Bristol from sources 25km away.

1848
Manchester built five reservoirs in the Langdendale Valley 15km from town.

1852
The General Board of Health recommended building new sewers in every town.

1853
Leicester was the first town to set up sewage works to treat waste water.

1859
Glasgow’s Loch Katrine works were opened providing the city with a supply of 230 million litres per day. At the time, the Corporation was warned about the dangers of lead pipe corrosion by soft acid waters.

1861
Aberdeen extended its River Dee tunnel system to supply 28 million litres per day.

1865
Joseph Balgazette designed the first interceptor sewers to carry London’s sewage down the banks of the Thames to be dumped into the estuary.

1867-78
New laws allowed town councils and local authorities to take water companies into public ownership.

1869
The “Native Guano Co.” at Hastings and Leamington dried and pressed sewage to sell as manure.

1880
Liverpool built Britain’s first all-stone dam on the River Vyrnwy in Powys.

1885
Water was checked for bacteria for the first time.

1890s
Bacterial sludge beds were first designed for treating sewage.

1892
Birmingham was given 18,000 hectares (45,000 acres) of Wales to build three reservoirs in the Elan Valley. These were opened in 1904.

At AquAid, we’re pleased to say that we offer the aforementioned potable water in a variety of forms, from bottle fed through to mains fed water coolers.

Water comes from 3 different sources throughout the U.K. and our water coolers are available nationwide, a few that are highlighted above. But do have a look at our nationwide coverage to establish which AquAid will best suit your requirements.

Plus, revenue from sales is donated by AquAid to sustainable charities like Christian Aid and The Africa Trust.

Water Coolers in the Workplace – It’s the Law!

Here is the ‘Law-uh’! (to be said with an old-school-spaghetti-Western-type-small-town-sheriff pronunciation).

In the U.K. the Workplace Health, Safety and Welfare Regulations of 1992, Regulation 22 places requirements on the employer with respect to the provision of drinking water.

It states:

1. An adequate supply of wholesome drinking water shall be provided for all persons at work in the workplace.

2. Every supply of drinking water required by paragraph (1) shall –
  (a) be readily accessible at suitable places; and
  (b) be conspicuously marked by an appropriate sign where necessary for reasons of health or safety.

3. Where a supply of drinking water is required by paragraph (1), there shall also be provided a sufficient number of suitable cups or other drinking vessels unless the supply of drinking water is in a jet from which persons can drink easily.

With this rather stern fact out of the way, I then proceeded to cross fjords, wade through rivers, scuba in ponds and was sadly, unable to find any unusual water laws per country.

What I did come across, however, were a plethora of unusual water tidbits and factoids.

  • If the entire world’s water were fit into a 4 litre jug, the fresh water available for us would equal only about one tablespoon.
  • Each Briton uses about 150 litres of tap water a day, but if you include the amount of water embedded within products, our water consumption increases to about 3400 litres a day.
  • One cotton t-shirt has about 25 baths full of water embedded in it. (Frightening that, but the thought of seeing Colleague X nekkid at the water cooler, the t-shirt needs to stay)
  • To produce just one pint of beer for example, takes 170 litres of water.
  • It takes 200,000,000 litres per second to grow food for the planet.

Overall, that’s a lot of water used and some of that isn’t even for drinking!

So, employer, be kind to your employees and install a water cooler that will allow them to keep hydrated and therefore, be happier, healthier and more productive during working hours.

And remember, it’s the law-uh! *cue sunset and whistle Ennio Morricone theme to The Good, The Bad and The Ugly and exit stage left*

BTWC – Before the Water Cooler

Ever wonder what came BTWC (Before the Water Cooler)? Here’s our first instalment about the history of water supply in the UK – hold onto your cups, because this timeline gets a little hairy at times!

1325

Franciscan Friars lay a pipeline into Cambridge from a spring one kilometre outside the town. Religious communities acquired a good reputation for water supply management in the twelfth, thirteenth and fourteenth centuries.

1439

The mayor of London asked the Abbot of Westminster to help provide fresh water for the 55,000 people of the city.

1460

A system of lead pipes was laid under the streets of Hull. Householders paid for pumps to extract the water.

1574-82

Peter Morris (a Dutchman) installed an ingenious pump below London Bridge. It was driven by a waterwheel and forced water up a tower over 100 feet high into a big tank, or cistern. The water was then strained through a mesh and fed through large wooden pipes and small lead pipes to houses in London. Five wheels had been built by 1582.

1584

Sir Francis Drake helped Plymouth Corporation persuade Parliament to build a water system to bring water 25km across the moors to the town. Water was stored in cisterns to be used without charge. The supply served for 300 years.

1596

Britain’s first flushing toilet called a water closet was designed by Queen Elizabeth’s godson.

1605

Oxford used covered gullies to collect spring water from Hinksey Hill. The gullies lead to a 90,000 litre tank protected by a stone house.

1677

In York, water from the River Ouse was pumped by wind power into a tank on the top of Lendal Tower. This provided water inside the walls of the city.

1775

Alexander Cumming re-invented the Water Closet.

1777

James Prosser improved it.

1778

Joseph Bramah perfected the modern flushing toilet.

Each week, we’ll wend our watery way through the historical dates to the big ol’ 21st century and see how far we’ve progressed in terms of having access to fresh, clean, potable water.

At AquAid, we’re pleased to say that we offer the aforementioned potable water in a variety of forms, from bottle fed through to mains fed water coolers. Water comes from 3 different sources throughout the U.K.

Plus, revenue from sales is donated by AquAid to sustainable charities like Christian Aid and The Africa Trust. The Africa Trust being all about people in far flung rural communities in Africa being able to have access to potable water. Rather fabulous, to think that you drinking water from a water cooler in Gretna Green means many people in Africa will have access to safe drinking water too.

Water and the Wobble …

(… that’s ‘Wobble’ not ‘Womble’)

We harp on about drinking water, water, water – with good reason!

I bet I’ll get your attention when I say that not drinking enough water can make you fat (wobbly). That’s because even when you’re mildly dehydrated, you can raise your stress hormone cortisol one to two percent.  Among the many things cortisol does is store fat and break down muscle.

Now, you’re going to hear naysayers claim the dehydration issue is overhyped. They argue there’s no double-blind, placebo based study to show you need eight glasses of water every day and that by drinking tea, coffee or fizzy drinks, you will actually reach your water quotient for the day.

This is not true. Whereas there certainly is some truth that most beverages are made up of water – the fact of the matter is – pure water is better. The ideal is to drink half your weight in water ounces. So if you weigh 200 pounds, you need to drink 100 ounces of water a day.

If you’re shaking your head that doing so is impossible, here are some tips that’ll easily help you achieve this:

  • Buy a funky monkey water bottle – if you have children – perhaps they can help personalise it for you (nothing like a few glitter star stickers to vamp up your bottle). Or, personalise it yourself.
  • Rally round the water cooler with your colleagues, or make a breakfast / tea / lunch time appointment with said colleagues to meet at the water cooler and fill up your water bottle. Take the bottle with you back to your desk.
  • Teach yourself to sip from your water bottle. Repeatedly. Throughout the day.
  • Replenish your water bottleHead back to the water cooler (the in-place to clear the cobwebs, catch up on the jibber jabber and do a 5 minute de-stress).
  • If you’re not able to buy a water bottle, then carry out the above 3 steps anyhow. Fill up your cup at the water cooler and finish the cup before you head back to your work station.

Now how easy was that?

You will save money, the environment and you won’t have to worry about that cortisol sneakily storing fat. You’ll also stay hydrated and enjoy the countless benefits water provides for your body.
