As we get ready to put out our pinhole cameras, colandars or don thick, dark perspex glasses, the moon is racing towards an intersection with the sun, creating a partial eclipse in parts of the UK.
The Sun’s distance from Earth is about 400 times the Moon’s distance, and the Sun’s diameter is about 400 times the Moon’s diameter. This means the disk of the moon can completely eclipse that of the sun, leaving just the Sun’s atmosphere, the corona, visible. Between two and five total eclipses occur every year with 240 eclipses on average every century.
Tomorrow we’ll be under a partial eclipse with totality being just North West of the British Isles. The South East will enjoy an 85% eclipse whereas the North West of Scotland will enjoy a 95% eclipse. It touches Penzance at 9:23 and leaves Lerwick at 9:43 so we have twenty minute window to view this awesome alignment of a star, a planet and a moon. But don’t look at the sun.
Here’s ten amazing facts about our sun – a G-type main sequence star:
1. Containing more than 99.8% of the total mass of the Solar System, the Sun is by far the largest object in the Solar System.
2. 109 Earths would be required to even fit across the Sun’s disk, and the Sun’s interior could hold over 1.3 million Earths.
3. Within the core of the Sun, the temperature (15,000,000 K) and pressure (340 billion times Earth’s air pressure at sea level) of it is so intense that nuclear reactions actually take place.
4. The Sun’s energy output, produced by these nuclear fusion reactions, is approximately 3.86e33 ergs/second or 386 billion billion megawatts.
5. The earth receives more energy (3.85 million exajoules per annum) from the sun in one hour than it uses in one year. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth’s non-renewable resources of coal, oil, natural gas, and mined uranium combined.
6. The process that takes this energy to the surface of the sun following complex stages is called convection.
7. This energy, released as heat as well as light, takes a million years to reach the surface.
8. The Sun also emits low density streams of particles, also known as the solar wind. These winds blow through the solar system at 450 km/sec and consist mostly of electrons and protons.
9. The Sun consists of the core, photosphere, chromosphere and corona, each with differing temperatures and components.
10. Existing just over 4 and a half billion years, it has burnt up about half of the hydrogen in its core. This leaves the Sun’s life expectancy to 5 billion more years, at which time, the Sun’s elements will “swell” up, swallow Earth, and eventually die off into a small white dwarf.
“We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature’s inexhaustible sources of energy — sun, wind and tide. … I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.” Thomas Edison (1847–1931) in conversation with Henry Ford (of Ford Motor Company) and Harvey Firestone (of the Tire Company) in 1931.

7 New Technologies That Could Radically Change Our Energy Consumption
Most of our focus on technological development to lessen our environmental impact has been focused on cleaner, more efficient methods of generating electricity. The cost of solar energy production, for example, is slated to fall more than 75 percent between 2010 and 2020.
This is a massive step forward, and it’s good that engineers and researchers are working for even more advancements in this area. But what about technologies that reduce the amount of energy we demand in the first place?
Though it doesn’t get as much attention in the press, we’re making tremendous progress in this area, too.
New Technologies to Watch
These are some of the top emerging technologies that have the power to reduce our energy demands:
- Self-driving cars. Self-driving cars are still in development, but they’re already being hailed as potential ways to eliminate a number of problems on the road, including the epidemic of distracted driving ironically driven by other new technologies. However, even autonomous vehicle proponents often miss the tremendous energy savings that self-driving cars could have on the world. With a fleet of autonomous vehicles at our beck and call, consumers will spend less time driving themselves and more time carpooling, dramatically reducing overall fuel consumption once it’s fully adopted.
- Magnetocaloric tech. The magnetocaloric effect isn’t exactly new—it was actually discovered in 1881—but it’s only recently being studied and applied to commercial appliances. Essentially, this technology relies on changing magnetic fields to produce a cooling effect, which could be used in refrigerators and air conditioners to significantly reduce the amount of electricity required.
- New types of insulation. Insulation is the best asset we have to keep our homes thermoregulated; they keep cold or warm air in (depending on the season) and keep warm or cold air out (again, depending on the season). New insulation technology has the power to improve this efficiency many times over, decreasing our need for heating and cooling entirely. For example, some new automated sealing technologies can seal gaps between 0.5 inches wide and the width of a human hair.
- Better lights. Fluorescent bulbs were a dramatic improvement over incandescent bulbs, and LEDs were a dramatic improvement over fluorescent bulbs—but the improvements may not end there. Scientists are currently researching even better types of light bulbs, and more efficient applications of LEDs while they’re at it.
- Better heat pumps. Heat pumps are built to transfer heat from one location to another, and can be used to efficiently manage temperatures—keeping homes warm while requiring less energy expenditure. For example, some heat pumps are built for residential heating and cooling, while others are being used to make more efficient appliances, like dryers.
- The internet of things. The internet of things and “smart” devices is another development that can significantly reduce our energy demands. For example, “smart” windows may be able to respond dynamically to changing light conditions to heat or cool the house more efficiently, and “smart” refrigerators may be able to respond dynamically to new conditions. There are several reasons for this improvement. First, smart devices automate things, so it’s easier to control your energy consumption. Second, they track your consumption patterns, so it’s easier to conceptualize your impact. Third, they’re often designed with efficiency in mind from the beginning, reducing energy demands, even without the high-tech interfaces.
- Machine learning. Machine learning and artificial intelligence (AI) technologies have the power to improve almost every other item on this list. By studying consumer patterns and recommending new strategies, or automatically controlling certain features, machine learning algorithms have the power to fundamentally change how we use energy in our homes and businesses.
Making the Investment
All technologies need time, money, and consumer acceptance to be developed. Fortunately, a growing number of consumers are becoming enthusiastic about finding new ways to reduce their energy consumption and overall environmental impact. As long as we keep making the investment, our tools to create cleaner energy and demand less energy in the first place should have a massive positive effect on our environment—and even our daily lives.
Two Ancient Japanese Philosophies Are the Future of Eco-Living
Our obsession with all things new has blighted the planet. We have a waste crisis, particularly when it comes to plastic. US scientists have calculated the total amount of plastic ever made – 8.3 billion tons! Unfortunately, only 9% of this is estimated to have been recycled. And current global trends point to there being 12 billion tons of plastic waste by 2050.
However, two ancient Japanese philosophies are providing an antidote to the excesses of modern life. By emphasizing the elimination of waste and the acceptance of the old and imperfect, the concepts of Mottainai and Wabi-Sabi have positively influenced Japanese life for centuries.
They are now making their way into the consciousness of the Western mainstream, with an increasing influence in the UK and US. By encouraging us to be frugal with our possessions, (i.e. using natural materials for interior design) these concepts can be the future of eco-living.
What is Wabi-Sabi and Mottainai??
Wabi-Sabi emphasizes an acceptance of transience and imperfection. Although Wabi had the original meaning of sad and lonely, it has come to describe those that are simple, unmaterialistic and at one with nature. The term Sabi is defined as the “the bloom of time”, and has evolved into a new meaning: taking pleasure and seeing beauty in things that are old and faded.
Any flaws in objects, like cracks or marks, are cherished because they illustrate the passage of time. Wear and tear is seen as a representation of their loving use. This makes it intrinsically linked to Wabi, due to its emphasis on simplicity and rejection of materialism.
In the West, Wabi-Sabi has infiltrated many elements of daily life, from cuisine to interior design. Specialist Japanese homeware companies, like Sansho, source handmade products that embody the Wabi-Sabi philosophy. Their products, largely made from natural materials, are handcrafted by traditional Japanese artisans – meaning no two pieces are the same and no two pieces are “perfect” in size or shape.
Mottainai is a term expressing a feeling of regret concerning waste, translating roughly in English to either “what a waste!” or “Don’t waste!”. The philosophy emphasizes the intrinsic value of a resource or object, and is linked to hinto animism, the notion that all objects have a spirit, or ‘kami’. The idea that we are part of nature is a key part of Japanese psychology.
Mottainai also has origins in Buddhist philosophy. The Buddhist monastic tradition emphasizes a life of frugality, to allow us to concentrate on attaining enlightenment. It is from this move towards frugality that a link to Mottainai as a concept of waste can be made.
How have Wabi-Sabi and Mottainai promoted eco living?
Wabi-Sabi is still a prominent feature of Japanese life today, and has remained instrumental in the way people design their homes. The ideas of imperfection and frugality are hugely influential.
For example, instead of buying a brand-new kitchen table, many Japanese people instead retain a table that has been passed through the generations. Although its long use can be seen by various marks and scratches, Wabi-Sabi has taught people that they should value it because of its imperfect nature. Those scratches and marks are a story and signify the passage of time. This is a far cry from what we typically associate with the Western World.
Like Wabi Sabi, Mottainai is manifested throughout Japanese life, creating a great respect for Japanese resources. This has had a major impact on home design. For example, the Japanese prefer natural materials in their homes, such as using soil and dried grass as thermal insulation.
Their influence in the UK
The UK appears to be increasingly influenced by thes two concepts. Some new reports indicate that Wabi Sabi has been labelled as ‘the trend of 2018’. For example, Japanese ofuro baths inspired the project that won the New London Architecture’s 2017 Don’t Move, Improve award. Ofuro baths are smaller than typical baths, use less water, and are usually made out of natural materials, like hinoki wood.
Many other UK properties have also been influenced by these philosophies, such as natural Kebony wood being applied to the external cladding of a Victorian property in Hampstead; or a house in Lancaster Gate using rice paper partitions as sub-dividers. These examples embody the spirit of both philosophies. They are representative of Mottainai because of their use of natural resources to discourage waste. And they’re reflective of Wabi-Sabi because they accept imperfect materials that have not been engineered or modified.
In a world that is plagued by mass over-consumption and an incessant need for novelty, the ancient concepts of Mottainai and Wabi-Sabi provide a blueprint for living a more sustainable life. They help us to reduce consumption and put less of a strain on the planet. This refreshing mindset can help us transform the way we go about our day to day lives.
