Recently, I saw The Ideas Economy's website and posted 2 ideas that I thought it would be useful. One was to design modular mobile smart housing that acts as a self sustainable unit; and the other a kind of 'lead net' that covers the entire nuclear plant in several layers before it actually explodes.

It just came to me after reading and following up the number of natural and man-made disasters that seems to erupt in a short span of 3 years. Regardless if the Mayans had been right about 2012,  we have to prepare for a definite real climate that is today and the near future.Highly populated areas, usually in cities, do not have much open space for escape. As such, I am thinking of the many possibilities of designing the units and the 'safety net'.

Climate change does not confine to the natural environment, about melting ice caps and the rise of sea levels. We are now facing another impending problem that is more instaneous and dire: terrorism. While we can add in rows of CCTVs, sending police and guard dogs to patrol at stations, airports, and sub stations; we must first eliminate any possible attack inland. For that reason alone, nuclear plants, oil rigs in danger points should be seriously considered for a permanent removal.The energy that we should use must be some form that we can contain in a much higher possibility. With the recent Fukushima Nuclear accident, signs are begining to show that the spread of radioactive pollution is going world wide. I think that is itself an expensive lesson to take and we have yet to see the full impact of the disaster.

I particularly liked the idea of solar energy. Many may not for the actual costs of producing them as compared to nuclear energy. But recently I have accidentally stumbled upon a paper by the late John O Blackburn, who wrote 'The Historic Crossover:Solar Energy is Now the Better Buy'.(see reference below)

I really wouldn't want to try nuclear in the long term given the change of climates now where there appears to be a rise in the number of earthquakes.Naturally people may doubt about statistics. Despite the nature of hard core research stats, we live under the sky to know what is really happening. Sometimes, a better trust is within us. Within me, myself, I do not believe that nuclear is the solution. It has never been. With the Fukushima Nuclear incident, I am more than adament to vote against nuclear energy. You know how the Japanese work. They are very merticulous and responsible people. If this could happen, I think its serious enough to make a resolution. -- Karen Fu, adapted from my own post to PhD forum.

Just posted my reply to Fil Salustri on PhD-Design forum list with regards to Nuclear energy.This is related to my ealier blog posts here. Sharing this on my blog and open for comments:

I just knew before I shut my eyes to sleep that someone would say this because
I didn't specify 'Fire'. My apolgies for missing the explaination.

Forest fires are natural occurance. But what I was trying to say was that
fire is something we cannot control effectively despite our advancement
in technologies. Fires can be started by humans as they could be started by
nature. With climate change and weather conditions getting drier in places
in California and Australia, prepare for more fires.

And many fires are initiated by humans.
And often it is very hard to recover. Often at the risks of firefighters.
One typical example is the forest fire in California in the US about 2
years back.
It was outrageous. (see reference links below my sig.)
And notably the fire caused in LA was human induced too.

Naturally occurring uranium is harmless, but after human intervention, this can
become harmful. The same could be said about gun powder. Some cultures use
it for fire crackers, celebration; while some used it to blast their
enemies' heads off.

The hard truth is there are people who have uncanny ways of doing things.
They are all innovative. But the cause for concern is the potential and the
extent of danger that each element poses. It I hold uranium. or even harmless
amount of untouched hydrogen, I am fine. But if I hold just hydrogen
alone and played
with it in huge amounts under pressure, I get a hydrogen bomb. Human ingenuity
can come up with ideas. Just that it has to be on the right track.
Hydrogen is abundant.
Wrong use, and its a terrifying abundant gas used for massive destruction.

True we are imperfect beings. And also due to our imperfection, we cannot also
be confident and sure that humans can design the best containment to fuels
that are potentially highly combustible. Both nature and humans cannot
ensure 100 percent
containment on any materials that we have to be totally safe. We need
precautions.
If we can prevent a disaster like Fukushima, and we are able to do now; I feel
we should take the precaution now like some of the EU countires are doing now.

Should have added to say that I don't even want coal / fossil fuels and anything
that exhaust fumes.  Anyway I've just stated my stand on coal now at
late bedtime.

I am trying to hunt for the stats. It comes with a large world map
showing where the
nuclear plants are. US has lots concentrated in the eastern part of
their country.
Then they show the costs of setting up a plant that is initially high
and covers itself
over a period of time. If memory doesn't fail me, in aroun 5-8 years
time, and its covered.
I should have recorded the link when I read it last week.
I will try to find it.

if thats the only game in town, then we are being utterly uncreative.
How can we be confined by that one source of energy alone when there
are clearly others at hand?

Its like talking about using only force to answer problems in the world.
There are many ways of doing it. Gandhi used peace for India to obtain
freedom for
his people. Singapore used to believe that merging with Malaysia as
the only way to
survive. People used to think that a country that has lots of natural
resources are the ones
which will prosper. It is via human creativity that makes our
prosperity and it is
humanity that keeps our society sustainable.
All these policies/inventions.ideas are man-made. We can change. For
that to change,
we must have guts to go into the unknown and venture. And fortunately for us,
we have other sources of energy that we can source. It may not be quick and cost
effective like nuclear, but we can design it with our expertise of new
forms of energy tio
answer problems. Policies to encourage smart use of energies. My blog
is about that.
If anyone's interested, its below my sig too.

The reality is do we need to really use
that much energy? Of course we don't. Thats another topic.

Its already 3:20 am here. I need to get some sleep. I only login an
hour ago. Shouldn't have.
But I did. So I might as well complete at least this email. I have
books to cover and notes to take
tomorrow.

Thanks for the advise. But I don't drink.
I only use wines for culinary purposes.
And I don't take caffeine to wake me up.
I use excercise. It works.  : )

I'll look for the infographic and the stats and post later.
