Actually, now that you mention it, I'd say a fair bit changed. Just look at the levels of Chinese emigration to Australia before 1901 vs after. Before there was plenty, particularlyl during the gold rush(es). After, well, shortly after federation the White Australia Policy came in.
You mean like deploying trams, light rail trains, heavy rail trains, buses, bicycle facilities and most importantly, walkable urban communities that can accomodate the needs of families, singles and others alike? Oh, those have all been developed. It's Europe that's actually implementing them/has already got them. Most of what the US puts down is mere lip service to what is considered a foreign notion.
You're forgetting that at current price levels (relative to those common up until two years ago or so) anyone who can produce oil -IS- producing oil.
Companies are bound by various fiduciary requirements to extract money to return to investors. Individuals aren't going to live forever and probably want to enjoy the spoils produced by their assets.
And if anyone is holding something back, it's such a small amount that it will never offset declines in the larger conventional fields.
Umm, guys, MD5 or otherwise, when most of the passwords on cisco.com are still the default password cisco123 (mine included, seeing as there's not much anyone can do with my login), just knowing usernames is often enough.
Wouldn't you need significant quantities of energy to make such a conversion? And didn't you see the episode where they were desperately short on Tylium, which is the fuel/energy source for their ships?
5mbit? I've got double that (10969/1134) on ADSL2 here in Melbourne, Australia (max speed on 1567 metres of 0.40 copper). And we're supposed to be a broadband backwater.
Cooling a unit generally means exchanging heat out of a machine and dumping it in the room. Tis not efficient when you then have to take that heat out of the room and dump it outside the building.
Picture a refrigerator in an air conditioned room. The heat radiates out the back, but then has to be cooled again by the air con.
With logic like this, can anyone say brownouts?
You know, some customers on the entry level ADSL plan at one of the ISPs I work for are on a plan that gives them 500MB of data transfer a month, with excess at 15c/MB. It's a pretty standard arrangement here in Australia.
If this sort of plan counts as a DDOS attack, I wonder if those users will start sending their excess usage bills to IBM.
I guess the rest of the world looks to America like they're your parents. You are slapped around by them, fear them, get slapped around again, then you grow up, move out, stop returning their calls, don't visit. Time passes, and later on you can and often do put them in the crooked nursing home of your choice.:-)
99%? Really? So if the IRA for example occupied the entire remaining 1%, that must leave an awful lot of muslims hiding in caves..
And let's not forget the wannabee Tim McVeigh's. He was also a christian extremist/terrorist, and there are a lot more like him, breeding like rabbits.
People from Queensland drink XXXX you dolt. In Victoria (where MelbourneIT is based) you drink VB. Only stupid Americans and a small number of very boring Aussies drink Fosters, which is why they are so desperate to flog their cow urine overseas.
And do all the employees there commute to and from work by electrified mass transport, or hydrogen vehicles with hydrogen produced by nukes or renewables?
Even the underpaid grunts who couldn't ordinarily afford a new unleaded car, let alone a new hydrogen car?
Nope, Hydrogen in fact has the lowest energy density of any chemical fuel. Even liquified you need over three times the volume to replace unleaded gasoline at the same application.
Whether it does or doesn't expand, can you think of any alloys that would last long under those extreme temperature and pressure conditions, particularly if they are being drained and refueled regularly?
You have to liquify the hydrogen or else the energy content of your shipload would barely be enough for half a day's trade at the typical gas/petrol/whatever station.
Also, if you ever wanted to use Hydrogen for freight, short of refueling your truck or train every few miles, you'd need liquified hydrogen.
Then you get to use the same energy source ten times over liquifying the hydrogen for storage and transport. It's ridiculously inefficient, and til we get fusion or zero point energy (GET BACK TO REALITY), it ain't going to work.
Absolute Zero: 0 Kelvin
Freezing point of Hydrogen: 13.97 Kelvin
Boiling point of Hydrogen: 20.41 Kelvin
Mean surface temp of Pluto: 53 Kelvin
Freezing point of Water: 273.16 Kelvin
Boiling point of Water: 373.16 Kelvin
How much energy do you think it would take to keep Hydrogen in that six and a half degree window so that it is liquified for transport but doesn't freeze and break the tanker in half? Then relate to that to the (rather low) energy value of the Hydrogen. Is it worth it?
Insanely harder than Natural Gas. And even Natural Gas is impossible to ship between continents in any serious volume (the load from an LNG tanker would barely keep the lights on in any serious size city for a few days, weeks if everyone was an energy miser).
If you have a source of carbon dioxide handy, you could just convert the hydrogen to methane (2H2 + CO2 = CH4 + O2) and just have the end users burn the methane in an internal combustion engine instead. Or use steam reformation to re-release the CO2 and split it from the Hydrogen.
Anyway, Hydrogen has a very nasty habit of leaking from just about every containment vessel ever produced. When it leaks, it goes up. Due to its extremely low weight, it reaches escape velocity and goes into space, though there's a good chance some of it will do a bit of melding with atmospheric ozone on its way up and even further wreck the ozone layer.
If we produce heaps of hydrogen and half of it ends up going into space, even if the energy source for producing the hydrogen is renewable, the fuel certainly isn't.
Not yet. Extracting oil is a net energy gain since you invest a small amount of energy into mining to get a huge amount. = Energy source
With Hydrogen, you invest a huge amount of energy into electrolysis or reformation and get back a much smaller amount of energy, then lose even more of it in storage losses and leakage (and leakage is a MAJOR problem with hydrogen, it is molecularly too small to be contained effectively and it also weakens metal storage tanks). = Energy loser

The Colony of New South Wales was founded as a penal settlement in 1788.
The Commonwealth of Australia was not, it was founded in 1901 as a Federation of six free colonies.
There is an important distinction.

Nope, Hydrogen in fact has the lowest energy density of any chemical fuel. Even liquified you need over three times the volume to replace unleaded gasoline at the same application.
How much oil would it take to build an appropriate number of dams or nukes? (and replace most or all of them every 30 years when they wear out)..

So I guess all the technical reasons why it can't (or probably shouldn't) be done should just be waved off.
What fuel source would the hypothetical tanker ships use anyway? Diesel?

How much oil does it take to build dams? And how many more dams can be built to supply the world's transport networks? One dam in Egypt? Pfft.
