Mobile Suit Gundam 00 Episode 3 [Changing World] & Episode 4 [Foreign Negotiations]

Here are the excerpts from Wikipedia about the plots in Eps. 3 & 4:

03 "Changing World"
Tieria returns to space with Gundam Virtue. The Union Army creates the Anti-Gundam Investigative Squad with Graham and Billy transferred from the MSWAD as official members. Meanwhile, Celestial Being launches surprise attacks in
South Africa, the South American continent over Taribian airspace, formerly in Venezuela and in Ceylon. Setsuna later faces off against Colonel Smirnov while conducting an attack against Human Reform League mobile suits. Later on, a JNN broadcast revealed that various militant factions in North Ireland signed a peace treaty, ending years of fighting between themselves, the British Army and the PSNI.

04 "Foreign Negotiation"
Colonel Sergei returns to the Reform League to head a new squad designated for capturing one of the Gundams, with Soma Peiris as his designated subordinate. Encouraged by Celestial Being's anti-conflict actions, the South American nation of Taribia declares its withdrawal from the
Union and declares it independence over the control of energy resources, prompting a Union military response, forcing Celestial Being to intervene. In Azadistan, Shirin Bakhtiar explains to First Princess Marina Ismail that the conflict is not as simple as it may first seem. Meanwhile, the Anti-Gundam Investigative Squad, in Flag Customs, engage Exia in Taribian airspace. Later on, pro-Taribian separatist politicians led by its prime minister are forced to drop their bid for independence after their forces were defeated by the Gundam Meisters.

==================================================================

Well, I’ve seen various opinions on the episodes.

But I just have another thought as I reflect on someone else' opinion.

Maybe we don’t necessarily need to treat this series as a Gundam series.

This series is seemingly more and more divert from some paradigms of other Gundam universe.

The two episodes are quite political compared to other Gundam series. It seems like the series is targeting a wider age group, esp. when comparing to Gundam Seed Destiny (which is “chaotic” in its political treatment.)

The episodes are really progressing on a story line, rather than selling actions and music videos (you know what I mean, don’t you?).

In episodes 1 & 2, it appears Gundams are invincible. But eps. 3 & 4 show that the Gundams are actually vulnerable.

Now, I am interested in how they develop the story of the first season, pause it and then start the second season.

This treatment of splitting the series in separate seasons is also a first in Gundam series.

Now, will someone tell me or give their speculation on how Union, AEU & HRL make up the technological gap between their MS'es and the "invincible" Gundams?

Pentagon offers a ray of hope in energy debate

Pentagon offers a ray of hope in energy debate

Out of this world … how the solar power station might look.

Out of this world … how the solar power station might look.


Richard Macey
October 17, 2007

THE debate over whether nuclear, solar, wind or clean coal is the energy of the future now has a new player. A report commissioned by an arm of the US Department of Defence has instead proposed lofting power generation into space.

Giant arrays of orbiting solar panels would collect sunlight, which would be beamed via low-power microwaves to massive receivers on the ground, or even directly to customers.

Published by the Pentagon's National Security Space Office, the report says the US should demonstrate the technology by building a pilot "space-based solar power" station, big enough to continuously beam up to 10 megawatts of power to the ground, in the next decade.

A more advanced station, "several kilometres across" and weighing more than 3000 tonnes, could deliver up to 10 gigawatts of electricity. While the report says the project would be a technological challenge, it "requires no fundamental scientific breakthroughs or new physics".

Sunlight's energy in space, where it is not diluted by the atmosphere, is enormous. A kilometre-wide band around Earth receives enough solar energy each year "to nearly equal the amount of energy contained within all known recoverable conventional oil reserves on Earth".

A basic technology demonstrator could be in orbit within six years, while a much bigger one could be operating by 2020, at a total cost of up to $US10 billion ($11.11 billion).

The report claimed the highly efficient microwaves would be significantly less dangerous than the noon-day sun. Microwave leakage at the edge of the rectangular ground antenna would be no more than that of a microwave oven.

In a malfunction "the likelihood of the beam wandering over a city is extremely low, and even if occurring would be extremely anti-climactic. If solar is considered 'green' energy, then [this] could be considered the ultimate green energy."

Following my comments on Gundam 00 - Episode 2, could this be the prototype of the space orbit solar power generator?

Now, the proposed power transmission uses microwave?!

And using the extra-terrestrial solar irradiance data from ASHRAE, which is about 1400 W/m2, the article says the station will produce 10 GW of power. That means 10E9(W)/1400(W/m2) = 7.1 million m2/ (or 7.1 km2) of solar panels at 100% efficiency. That is a square of 2.7km x 2.7km!!! 1400 football pitch!!!

Now just what will be the cost, pay back period and the embodied energy of the power plant?

How much will you pay for this kind of electricity?

Mobile Suit Gundam 00 - Episode 2 [Gundam Meister]

I am not too sure if I can give a good commentary to Gundam 00 Episode 2 - "Gundam Meister".

Episode 1, I believe, is well received. This may be because the last Gundam series, "Gundam Seed Destiny" was infamous for its plot and story pace, etc.

Now for episode 2, seems like some bad elements from GSD resurrect in Gundam 00!

In this, I refer to the superiority of the Gundams. Exia "dances" around the HRL's MS'es and chops them like vegetables. It is also hit by a direct shell without the slightest dent!

Also, the GN particles has so many superior features, like cooling agent when the MS'es enter the atmosphere.

I also discuss this with a friend. How can you propulse the Gundam with the GN particles? Classical physics or even quantum physics all seem useless in the Gundam universe. (I think we need a "Gundam physicist" to explain the science in GN particles uses!!)

And as an engineer, esp. in energy efficiencies and ESD, I really like to know how the energy generated by the "PV arrays" (I am assuming here.) transmit the energy to the earth's surface and distribute to every power demand locations. What will be the cross-sectional area(s) of the conductors / power lines? We are talking about roughly one-third of the Earth's energy need through one "Tin-Chu / Sky Column"! (Three Sky Columns only to provide the whole earth's energy use!)

And what is the area required to generate that much of energy? (On the earth surface, solar intensity is roughly 500W/m2. Possibly higher when the atmospheric scattering effect is eliminated, but the solar intensity in stationary orbit is still a finite number!) (PS. ASHRAE 1997 Fundamental page 29.14 Table 8 states that Extraterrestrial Solar Irradiance ranges between 1336-1417 W/m2.)

Well, maybe we better focus on the plot, not the science. But this episode seems muddying the plot. I may need to look at it again to see what it intends to do to the series, if not time filling.

Mobile Suit Gundam 00 - Episode 1 [Celestial Being]

Well, I haven't looked at other people's review about this new Gundam Series. So here are some of my comments about Episode 1:

  • The overall - The overall feel is not bad. But the background of this alternate world is not revealed too much now. It is still early days. Past experience from Seed and Seed Destiny show that the pacing at the start can be slow; but then the pace goes berserk and hard to catch up! (Destiny pace near the end is really crazy! Recap, rush, recap, rush.....) Let's hope this one will have a good pace but not too fast that we can't follow.
  • Characters - The characters design appears fine for me. But one funny thing is that I see"Lynn Minmay's" look alike. Is that a joke on Macross?
  • Mecha - There are many criticisms to the mecha design saying that they divert from the "classical" Gundam design. Well, the Gundam's seem some little facelifts of previous Gundams. But I am not too sure about the "Enact"!!! It looks like the mech from Rahxephon to me. And about the heavy MS of HRL (Human Reform League 人類革新連盟) ....... can't see them before they becaome canon fodder. But from the designs, I think they are ... "soul-less".
  • Philosophy - "Stop war by war"...... Yes, as one of the characters say, this is ironic! Isn't this familar from Seed and Seed Destiny! But then I think, well, what is it behind the war? You stop the acts of war. But you can't stop the warring minds! And the issue before war whcih is energy and resource depletion cannot be resolved by suppressing the "acts of war". So what is Yōsuke Kuroda's idea behind the series? Anyway, this could be only a commercial vehicle for Bandai to sell their products! I may not help myself to get some Gunpla anyway!

So my score for this episode is 7.5!

Sustainability consultant discusses greenhouse issues

Sustainability consultant discusses greenhouse issues


I was at home watching this while surfing. This clears up some misconceptions about "Sustainability" and "carbon neutral".

Australian Broadcasting Corporation

Broadcast: 03/10/2007

Reporter: Andrew Robertson

Jonathan Justen from sustainability consultancy firm Energetics discusses carbon neutral businesses.

Transcript

ANDREW ROBERTSON: 'Carbon neutral' has become a catch phrase if the business world as companies scramble to adjust to the demands of global warming. But what does 'carbon neutral' really mean, and how can business meaningfully contribute to lowering the output of greenhouse gases? Jonathan Jutsen is a founder of Energetics, which for 23 years has been one of Australia's leading consultants on sustainability and greenhouse issues, and he joined me in the studio earlier this evening.

Jonathan Jutsen, welcome to Lateline Business.

JONATHAN JUTSEN: Thank you.

ANDREW ROBERTSON: Does being carbon neutral actually lead to less carbon being pumped into the air or just to offsets like planting trees?

JONATHAN JUTSEN: Well, ideally it does lead to reduction in production emissions. and what we are recommending very firmly to companies and I think this is starting to become accepted, is that the right way to go carbon neutral is to in fact reduce your own carbon footprint first, which means improving energy efficiency and doing other measures internally within your organisation which will reduce carbon emissions before you start looking outside the organisation. And even when you look outside the organisation - to start with green power, which comes from new renewable sources, before you go to buying other types of offsets.

ANDREW ROBERTSON: What are some of the simple things that companies can do to reduce their carbon output?

JONATHAN JUTSEN: Well, most of the carbon output from most companies is related to their own energy consumption. And so improving energy efficiency in their operations is the primary thing that most companies can do in the short-term. And it has another benefit of course, they actually save money as well. So we're recommending and most reputable people in this field do recommend that companies focus on improving energy efficiency as the first step.

ANDREW ROBERTSON: Every company in the world at the moment seems to be saying that they're green. Just how green is business?

JONATHAN JUTSEN: You know, they say green is the new black, but I think people are fair to be slightly cynical because I think there is a variability. I mean, some companies are taking this very seriously. They see it as a core part of their business and want to do the right thing by the community and by their own organisation. Other companies I think see it as a good opportunity to raise their profile, or maybe change their public positioning, and really don't understand the full nature of the obligations and the cost involved to become carbon neutral in a responsible way.

ANDREW ROBERTSON: But how do you get business to do even basic things like turn the lights off at night? I mean, anyone that drives past an office block or a big company headquarters at night sees all the lights on.

ANDREW ROBERTSON: Look, I think that is the way that most companies have been up until now. I don't think many companies in Australia have, until the last few years, taken improving energy efficiency and reducing carbon emissions as a serious part of their business. It's been a relatively low cost for a lot of companies. Energy costs are relatively low in Australia. And there are very few companies that have seen that sort of resource efficiency and carbon management as a core part of their businesses, but it is starting to change quite rapidly.

ANDREW ROBERTSON: You say on your website that the challenge for all Australian companies, analysts and shareholders is to ensure that there's a common understanding of what it means to be carbon neutral as well as agreed standards for each of the settlements in achieving that. How do we get to that point?

JONATHAN JUTSEN: There are some real issues with carbon neutrality. And those are not just around what sort of offsets and how reliable they are and do they come from the right sorts of sources. It's also how you calculate your carbon footprint - the amount of carbon that you emit not only for your own organisation but through third party activities. So there is a need for common standards and they are starting to develop in Europe, and global standards are starting to come about.

But we have still got a problem that in Australia we have standards through the Australian Greenhouse Office, the greenhouse friendly program sets a local standard, but unfortunately not all carbon neutrality is done to any of those standards and there is no obligation in the way that companies report to ensure that they are reporting to those standards. So there is a need for a lot more rigour and I think probably some regulation around how companies can report this sort of information. I understand that the ACCC is starting to move in this direction at the moment.

ANDREW ROBERTSON: Just on the issue of regulation and the role of government - we don't have a carbon trading system in Australia and at the moment it's been foreshadowed that it won't start until 2012. How big an issue is that?

JONATHAN JUTSEN: I think it's a very big issue. For two reasons. Firstly, I don't believe carbon trading in itself is going to be enough to make the sort of carbon reductions that most scientists believe are necessary to stabilise the world's climate at some sort of reasonable level. And not only that, it will require, even when the carbon trading program is in place, will require other measure, including regulation, including regulation of energy efficiency performance metrics. There will be a whole range - education, public education, there will be a whole range of policy implements that are required other than just the carbon pricing. But as well as that, we can't wait three or four years with inefficient buildings going in, with inefficient factories going in, with people buying inefficient cars and houses, we can't wait three or four more years before we start to take action. We have to take action now, so there is a need for interim steps regardless how effective the carbon trading mechanism is.

ANDREW ROBERTSON: And what should those interim steps be?

JONATHAN JUTSEN: I think they should be very targeted regulations in terms of performance of appliances, efficiency of buildings, both commercial and residential buildings. I think there is a need for a regulatory approach. I think there should be financial incentives, substantial incentives for both businesses and householders to accelerate the implementation of energy efficiency measures in their facilities. I think these measures are absolutely essential.

ANDREW ROBERTSON: Carbon trading will lead to alternative, hopefully investment in alternative energy. But alternative energy will be much more expensive.

JONATHAN JUTSEN: Yes, and I think one of the things that I find rather frustrating being in the energy efficiency area - at least half the solution's going to come from energy efficiency to global warming, and yet our government, certainly at a federal level, hasn't put very much effort or investment into the energy efficiency area. There is a lot of focus on green supply, but energy efficiency actually reduces costs and will improve the economy and reduce costs not only for businesses but for householders. So there should be incentives and research and development and regulation going into that area and not just the into green energy.

We've seen new regulation just come out about green power requirements, but there's no increased regulation coming through on the energy efficiency side. And because it's the most cost effective way of getting to where we want to get to, it's amazing to me that there hasn't been a lot more focus in this area.

ANDREW ROBERTSON: What are the opportunities for being at the forefront in managing carbon output, and what are the costs for business in being left behind?

JONATHAN JUTSEN: Well, it's like any major change that impacts on business. There are the people who are going to be at the forefront of the activity and are going to be influencing and developing and creating markets and are going to be managing the risks very effectively in their business. And these people are going to be at the forefront of a business opportunity which is going to be huge globally.

To improve energy efficiency and to invest in green alternatives to reduce carbon emissions, the expectation is there's going to be $5 to $10 trillion invested globally in the next 40 years. So, I mean, this is a major opportunity, it's not just - we're not just talking about risks, and those companies who are at the forefront of that area will have the opportunity to take advantage of those new business changes. Whereas other companies are going to be just buffeted by changes. And we talk to executives quite often at senior levels of many companies, and I think many of them believe that the future is just going to be an extension of the past with a little carbon price tacked on the top. They don't recognise that this is potentially going to change not only pricing of products quite substantially, particularly energy intensive products, it's going to change the way we have to handle materials, it's going to change the way consumers look at their purchases, they're going to be much more sensitive about the perception of carbon-friendliness about products. It could have very substantial changes in the business environment and companies that don't take this into account now and just think the future is going to be pretty much the same as it was for the last 40 years are going to get caught out.

ANDREW ROBERTSON: So there's a revolution on the way?

JONATHAN JUTSEN: Absolutely.

ANDREW ROBERTSON: Jonathan Jutsen, thank you very much for your time.

JONATHAN JUTSEN: Thanks for having me.

Ubuntu 7.10 Countdown




Waiting for the Ubuntu Gutsy Gibbon!




New features since Ubuntu 7.04

GNOME 2.20

Gutsy Gibbon Beta brings you the latest and greatest GNOME 2.20 with lots of new features and improvements.

Desktop 3D effects

Compiz Fusion is enabled by default and will bring 3D desktop visual effects that improve the usability and visual appeal of the system. Ubuntu 7.10 automatically detects whether the hardware is capable of running compiz; if not, it falls back to normal desktop. Additional effects can be enabled in "System/Preferences/Appearance" under the "Visual Effects" tab. There you can also disable the effects entirely.

Desktop search

The deskbar applet is now included in the default configuration. It allows quick access to your common actions, including opening web bookmarks and searches, sending messages to your contacts, and more.

  • deskbar-search.png

The Tracker indexer has been added to the desktop, making it easier and faster to search for your documents, photos, music, videos, chat logs, and all other files. You can use Tracker in the search dialog, the file selector, nautilus, or the deskbar applet.

Fast user switching

It is now possible to easily switch between user sessions without the inconvenience of entering your username or password numerous times, a time-saver on computers shared by multiple users.

  • fast-user-switch-applet.png

Firefox plugins in Ubuntu

Firefox now comes with an improved plugin finder wizard that allows users to search and install packaged plugins easily, bringing users a richer web-browsing experience with the integrated security support of the rest of the Ubuntu system:

  • pfs3.png

In addition, users can now open the Ubuntu application installer with a list of packaged Firefox extensions available by clicking on a link in the Firefox Addons dialog:

  • gai-xul-extensions.png

Dynamic screen configuration

Several drivers, including ones for ATI, nVidia, and Intel graphics chips now support the X Resize and Rotate Extension (xrandr). This enables dynamic monitor detection, and resizing and rotating of video output, for no-fuss support for projectors and external monitors.

If you have this hardware and used MergedFB / Xinerama previously, you may need to update your X configuration to use this new feature.

Graphical configuration tool for X

You can now configure what driver you want to use for your graphic card, change the default resolution for all users or change your monitor's refresh rate without having to turn to the terminal. A new GUI has been added making it easy to adjust your video and monitor settings. This tool can also set up dual screen capabilities for cards that use the Xinerama mode.

  • displayconfig1.jpg

Fully automatic printer installation

Printers are now automatically configured by merely plugging them in and turning them on. Printer setup cannot get any easier!

  • printer-auto-detection.png

Handling of non-free device drivers

Restricted-manager can now handle drivers which are free in themselves, but which require non-free firmware or other packages to operate. Only three clicks are needed to fetch and install firmware for wireless cards with Broadcom chipsets, and for a number of Winmodems commonly found in laptops, provided that you have an alternative Internet connection.

When restricted-manager detects hardware for which a restricted driver is available, a notification window pops up:

  • r-m-newdrivers.png

NTFS writing

While previous Ubuntu releases only supported read access to Windows (NTFS) partitions, Gutsy Gibbon now fully supports reading and writing to them, by integrating the NTFS-3g project. This significantly eases file and document sharing with Windows.

Power consumption

Ubuntu includes the latest Linux kernel, featuring dynticks. It allows the processor to use less power and produce less heat. For laptops this means more battery life and burn-free laps and for desktops and media center PCs, a quieter, cooler environment.

AppArmor security framework

This easy-to-deploy kernel technology limits the resources an application is allowed to access and can be used to provide an added layer of protection against undiscovered security vulnerabilities in applications. Head to the AppArmor user guide to learn about this new security feature.

Additional installation profiles for Ubuntu Server

New pre-configured installation options have been added to the Ubuntu Server CD. Mail Server, File Server, Print Server, and Database Server options join existing LAMP and DNS options for pre-configured installations, easing the deployment of common server configurations.

Profile-based Authentication Configuration

Deploying authentication configuration has become a lot easier with the addition of auth-client-config. Files may be added to the profiles database, allowing for an administrator to set up a single profile for site-wide network authentication roll-outs. Find out more about AuthClientConfig.

Improved thin-client support

The speed of LTSP thin clients has been greatly improved through the use of compressed images, and LDM, the thin-client login manager included in Edubuntu, also now has support for autologin, multiple servers, and unencrypted graphics transport as an additional speed boost.
