It will however push other nations to follow the example of researching alternative energies!

I hear what your saying about not everywhere having the same sun power, but if that city is a complete success then the rest of the world could design their cities based on Masdar and instead of mostly relying on sun just use another source of energy like wind/tidal etc.

I think its just important that a city will be built completely green, and that someone takes the first step to do this, and then perhaps other cities will follow in a green path...before you know it we could have 5 green cities world wide, and 50 years later we could have 20 green cities and so on, each city using different types of green power of course based on their location and options available to them.
 
characterless dump

It has plenty of character and if you've seen the vision imagery of the city you can see heritage areas that kind of stick to the olden ways of design at least.

Anyway, it is the future and the direction things need to head if humans want to carry on living on this planet. We won't be alive to reap the benefits of it anyway so why does it bother you that much how it looks. Future generations won't care for a nice cottage house with trees and grass and **** :p

And we are pumping pollutants from fissile fuels and all other manufacturing. It's what happens. we invented, we refine, we recycle and we get cleaner.
 
it's a good 50-80 years away?

Because few people are working on it. Time and money is being wasted IMO on other things such as windmills. We're having a huge offshore windfarm which is costing millions being built right off the coast by me. What a total waste of money IMO. Millions it is costing that could have gone into the development of the most incredible energy generation yet. IMO (once again :p)

Yep, looking at 2050 for earliest comercial reactor, depending have DEMo reactor goes.
How are you not certain it could be less?

construction timelines.

ITER
2006-11-21 Seven participants formally agreed to fund the creation of a nuclear fusion reactor.[9]
2008 Site preparation start, ITER Itinerary start[12][Full citation needed]
2009 Site preparation completion[12][Full citation needed]
2010 Tokamak complex excavation start[citation needed]
2011 Predicted: Tokamak complex construction start[12]
2015 Predicted: Tokamak assembly start[12]
2018 Predicted: Tokamak assembly completion, start torus Pump down[12]
November 2019 Predicted: Achievement of first plasma[18]
2026 Predicted: Start of deuterium-tritium operation[18]
2038 Predicted: End of project

DEMO
# Conceptual design is to be complete by 2017
# Engineering design is to be complete by 2024
# The first 'Construction Phase' is to last from 2024 to 2033
# The first phase of operation is to last from 2033 to 2038
# The plant is then to be expanded/updated
# The second phase of operation is to last from 2040 onward

PROTO is a beyond DEMO experiment, part of European Commission long-term strategy for research of fusion energy. PROTO would act as a prototype power station, taking in any remaining technology refinements, and demonstrating electricity generation on a commercial basis. It is only expected after DEMO, meaning a post-2050 timeline, and may or may not be a second part of DEMO/PROTO experiment. This might possibly make PROTO the first commercial Nuclear Fusion Power Plant in the world.
 
The City of Masdar looks set to be the only green city on Earth with no water being wastd and all energy generated through solar power and other completely green methods.

Question - The materials, labour and infrastructure being used to build the city, where is it sourced from?
Not knocking the end concept as it's ideal, but cities don't make themselves unfortunately. Not followed it so curious.
 
Gahh that city looks all modern and horrible. Totally not my cup of tea. What's wrong with old fashioned country style houses?

not energy or waste efficient. The design is to minimise power consumption, water and the like as well as producing energy and water cleanly.

Good point but the city is still worth making imo for many reasons such as the long term benefits and also persuading the rest of the world and other corporations and governments to do the same.

Every little last thing is logged and offset. Everything is sticktly controlled and recycled. They have inspectors going around to check what builders are doing with every little of scrap or empty mastik tube. It even takes it to account human food and travel.

One of the first things they did was build the solar array and connect to national grid to off set power usage.
 
Where's their actual price tarifs, I hate power companies they always hide it away.

It's WebSaver 11 Dual Fuel.

billions are being spent on it it takes years to build the palces.
 
Solar is very much feasible...in other parts of the world. CSP can be done with plentiful materials, making it feasible. If you have a lot of unused ground and a lot of strong sunshine, solar power is feasible. Since we have neither in the UK, it isn't at all feasible here. It is feasible to generate it in north Africa and transmit it here, though.

Wind would be feasible higher up, at least on paper. If you didn't mind creating huge no-fly zones and you had some way of dealing with extremely long and heavy cables falling down if something went badly wrong and they snapped.

Wave and tidal are promising in the UK as we have a lot of coastline and a lot of waves.

I think we need to be using a mixed bag approach, with various different forms of generating electricity. Including nuclear fission right away and nuclear fusion if it becomes viable as a power source at some point in the future.

Just looked at the wiki article for CSP (concentrated solar power), it does indeed look far more promising than photovoltaics, however there is more to feasibility than technology (and I am dubious of the efficiency of a long distance power grid) - the prospect of buying electricity form African states is even worse for energy security than oil. We need more home grown energy production - nuclear all the way, at least the countries selling uranium are mostly friendly.
