When Sea Level RisesWhen Sea Level RisesWhen Sea Level Rises by coshipi
Or possibly falls.
You push a boulder up a small rise
Out of a little dip
It may roll away
Far down the other side of the hill
Into a valley you couldn’t see.
The climate could be like that.
Quite likely it’s up hill all the way.
There are nuclear power stations
All around the coast.
If sea level rises
They’ll get swamped.
A half metre rise doesn’t sound much
Has made wide flat areas
That absorb storm energy
Half a metre of extra depth
Will mean they absorb
Very much less
And every storm will batter
Anything on the coast.
Are better than Soviet ones
So they said
And Japanese reactors
Are just as good as British ones
So they said
If sea level doesn’t rise
Because the changing climate
Goes the other way...
Then the Ice Is Coming
What advancing ice
Will do to nuclear reactors
Doesn’t bear thinking about.
Even just a lower sea leve
Wind and Sun: IntermittencyWind and solar power, the two main renewable energy sources, are intermittent and variable. This has two implications: firstly, that the total amount of energy they can produce is less than it would be if they produced continuously at their maximum output; and secondly, that some other source of energy is needed in addition if a continuous supply of energy is required. This doesn't mean that they're useless, but it does affect the economics of using them.Wind and Sun: Intermittency by coshipi
The characteristics of the various electricity generating technologies are all different.
Nuclear power has very high capital costs, and low fuel costs. It can run almost all the time, at its maximum output. Because it has high capital costs, it wants to run at maximum output as much as it can, because it costs almost as much when it's idle as it does when it's working hard. It likes to supply base load the power that's still in demand at the times of minimum demand, usually the middle of the night. At a time when the au
Capacity factorCapacity factor is a so-called figure of merit for power stations (and various other capital assets). For a power station, it is the ratio of the total amount of energy generated over a period to the amount that would have been generated if the output had been maximum for the whole period.Capacity factor by coshipi
So if the output was actually maximum for the whole period, the capacity factor would be 1, normally written as 100%. If the output was 50% of maximum for the whole period, the capacity factor would be 50%; if output was 80% for half the time and zero for the other half, the capacity factor would 40%. Typically the output varies up and down between 0% and 100%, and you have to average the percentage output.
The reason why output is less than 100% of maximum could be either because the demand for power is not there, or because the power station is for some reason unable to deliver 100% of its maximum power some of the time.
Other things being equal, the higher the capacity factor, the be
Bedknobs and Broomsticks - and a lovely cup of tea“The crows wait for me. They’re there every morning, when I go to the bus stop. And if I don’t bring food for them, I hang my head in shame.”Bedknobs and Broomsticks - and a lovely cup of tea by Lethus1
Amethyst looks at me seriously over the top of thick black glasses. She is a plump lady, shrouded in a long, hooded shawl. The colours are muted, but still bright enough to stand out against the gloom. She raises her hand to make a point, and the shawl flaps around her elbow. Overall, she bears a striking resemblance to a stern, tawny owl.
Her brow is furrowed, but there is kindness in her blue eyes. When she stands, her red hair swings gently in a waist-long ponytail. Had she been born a few centuries earlier, both those physical traits would most likely have meant the death of her.
Amethyst Selmaseline is a witch. A practitioner of mystical arts. Lover of animals. A being of light, temporarily inhabiting a mortal body. She is also the owner of a small shop in Reddish, just outside Stockport. And the owner of many, many s
Shanty TownsShanty Towns by aldwarke
Ghost-like waifs in ragged shrouds haunt refuse tips
Haggard mothers dry suckle big bellied babes
Beggars, beseeching, stare from sightless sockets
Our brothers and sisters in another land.
Who live in shacks of tin in shanty towns.
Don't tell me about your bloody headache!
Free...The world was a giant surface of white and I stood in the middle of it, surrounded by nothing but wind and snow. Suddenly the imaginary path I was following turned red. I stopped and looked back for a second. The setting sun broke free near the horizon and painted everything red.Free... by Ikabe
Snow and fire.
On the ground behind me, the footsteps I made just a minute ago started disappearing under the freshly fallen snow. It felt right, somehow.
The snow glittered, energized by strong winds and the last rays of sunlight of the day. It was a strange, calming sight; accompanied by thoughts of absolution and achievement. I have been waiting for this all my life, I realize that now.
Life entwined me with its own realities, plans and schemes, but this is what I was always meant to do. I guess I needed to grow older, collect all those little victories and defeats Life brings; experiences and memories; failures and lessons, before I was ready to make such a radical step.
Of course now, standing
