Question. As a kid, taking a focussed light beam - we used to burn things. Used a magnifying glass.
Would not an intense focussed beam be used as a weapon by the dear USA? I really cannot see energy harvesting in space being financially viable for them - but a weapon, in space, not requiring an additional power source - now that I can see. Perhaps I am a pessimist - but that is the type of thing super powers do when they feel under threat.

They aren't allowed to put weapons of mass destruction in outer space. There is a treaty called the Outer Space Treaty that forbids it. Don't know how long it will last, but there will be a huge outcry if the US breaks it. This power station might be a disguise but I doubt it. It transfers the power to the ground using radio waves (microwave). The receiving Antenna is 6.5 x 8.5 kms. Not focussed enough to cause any serious damage.

The fact of the matter is that America has been having a power crisis for almost a decade now.
I remember a few years back, large parts of California were without power for days.
They almost make Eskom look competent.
The US has finally realised their predicament and are looking for possible solutions.
I doubt this is a weapon in disguise.

I hope USA blow sum shiat up, news has been so boring recently.

not a chance...They almost make Eskom look competent
eskom is one of the few companies in the world who try discourage ppl using their product...
and heres a killer. was doing work at megawatt park on friday, and they were running on a gen....mildly amusing
I can picture in my mind a world without war, a world without hate. And I can picture us attacking that world, because they'd never expect it.

For what it's worth, we in SA pay less for electricity than most 1st world countries.thealluseless wrote:not a chance...They almost make Eskom look competent
I know power is cheaper here than in Australia and New Zealand.
Also, we could easily meet our countries power requirements if Eskom stopped supplying power to other parts of Africa.
But then most of Southern Africa would be without power.
I'm not defending them, I'm just pointing out that we are probably better off power-wise than our friends in America. Now and probably in the long run.
The 2 new plants in WC, which give the region 1050 megawatts of electricity at peak time.
Plus they have plans bring a mothballed plant back online and have 3 new plants fully operationa by 2012

So basically another 5 years of power shortages which will most likely get worse as demand rises each year.Plus they have plans bring a mothballed plant back online and have 3 new plants fully operationa by 2012
I'm really not looking forward to winter when demand is much higher than it is at the moment (bad weather or not)

Winter/summer consumption rates do not difer that much here in Durbs.
The rest of you will just have to tough it out
A gross oversimplification would be that we live in 3D space and time would be the 4th dimension. Therefore, if you wanted to describe the coordinates of an object in space, you would need it's x,y,z co-ordinates (relative to a reference frame) and the time it was there. This is a very simple model of spacetime. In reality it is far more complicated (general and special relativity and quantum physics).

Stationary is a relative term. There are few absolutes in physics.
Time dilation means that one objects experience of time varies by how fast it is travelling relative to another object. An object travelling close to the speed of light ages and experiences time very slowly, while other objects experience time normally. They've managed to measure this phenomenon in satelites and AFAIK even GPS's take this into account.
Nothing is truly absolutely stationary. My computer may be stationary relative to me, but the earth is rotating, so relative to the centre of the earth it is moving (with me). And the earth is moving around the sun; and the sun around the galaxy; and the galaxy is moving relative to other galaxies and space is expanding.

ok ok i get it now_thanks Hex_ hope you don't mind me asking all this... when some1 knows a bit or a lot more than i in a certain matter i tend to ask a lot and you seem like you know about this.
back on point: that would mean if something were to truly be stationary relatively to all, it would be out of time so to speak,right?
