The brightest "Stars" are pretty much always planets, there are a few bright stars but the first to start appearing at sun down are normally planets. you should be able to see mars and Saturn above the moon tonight.

I love it when you can catch a satellite, normally you don't have to wait more than 15mins or so within 2 hours of the sun set and you will see what looks like a faint star gliding across the sky, if you catch the space station it is very bright.

-------

Actually the space station in visible from Sydney at 5.36 this afternoon. here is its schedule.

and here is its current position.

That's awesome. Thanks VC.

Never knew you could actually see satellites or the ISS.

What telescope do you have there to see them? Just your normal one? Depends on the zoom/lens ey?

You don't need a telescope to see the space station or other satilites, you can easily see them with the naked eye.

The space station will be brighter than all the stars, it will just look like a big star gliding across the sky, you can generally only see them within 2 hours of sun set though, because they have no lights on them, so you need to be close enough to sunset that it's getting dark, but the satilites a few hundred kilometres above are still lit up by the sun.

There is so many satellites up there, you should be able to spot one within 15mins once you know what to look for.
 
Anyone else heard of Tony Seba? Short story is he is an energy disruption guru who believes that within just 15 years conventional energy production and transport will have been rendered obsolete by the revolution taking place in batteries, solar power and electric cars.

Certainly worth considering in the context of how significant scientific progress can be in our future. Also has huge implications for many current industries and investments.

AGL Energy chief executive Andy Vesey has singled out the advance in battery storage as the factor that will "change the world" of energy investment over the next few years, with a significant impact on both businesses and individual consumers.

Speaking at The Australian Financial Review and J.P Morgan Chanticleer lunch in Sydney, Mr Vesey said AGL was expecting a 60 per cent reduction in the cost of batteries over the next five years, while performance would improve as investment poured into the chemistry and material science underpinning the technology.

For anyone interested in a more detailed analysis of why and how energy disruption will occur in a very short time check out this presentation.

Very compelling. One wouldn't want to be in a dead end industry..

I've been hearing about the inventive genius of this guy for decades now, and would dearly love to see some of his discoveries explored more deeply.

Whilst I cannot vouch for the authenticity of the information contained in the following site, it's coverage of certain examples of Nikola's discoveries does appear to tie in with information I'd already encountered elsewhere.

Anyone in the electrical engineering sphere knows all too well about Nicky. Myths seem to have attached themselves to him e.g. Over unity generators, Zero point energy, Orgone energy.
 
They reckon the part of the brain that rates the pain response has been identified. All these years I have teased my sisters that men have a lower threshold of pain because they are hunters and don't fall pregnant. At last recognition: :D

The typical "mad professor", but a very influential one in the electricity business.

Wireless transfer of power was a great idea, but it would have been 'free energy' so no one would finance it.

Interesting.

The problem I have with his assumptions and conlcusions, and this is just top of my head out of thin air stuff... are:

1. He's ignoring the real life political, influence peddling, lobbying and other form of capitalist inventiveness to affect policies and adoption rate; and only look at the real economic benefits as though all consumers are given facts, as though all the oil barons and masters of the universe will stop aside and let the most innovative and most efficient entreprenuer win.

If we assume market efficiency, capital and law are given to those with best solution... world will be at peace and most politicians will be out of a job; and greenies communists won't have such a hard time convincing people of the dangers of CC.

2. Not sure if his cost curve was assumed independently of the reduction in new cars needed.

If EV and self-driving cars meant 80% of new cars no longer needed - i.e. sell less cars - will the scale economics still be there to bring that costs down?

3. If self-driving capabilities are there and so widespread as to make 80% of road/freeways obsolete because humans are generally inefficient driver etc., why not adopt it to public transport system - say smaller buses, put it on a shuttle van/minibus;

The car as a service, yea that was good... maybe he meant for it to apply to all areas and not just the city/metro yuppies.

Solar is interesting. From experience I noticed that for around $3k and 16 panels, our entire house could live off the solar system and only need to pay something like $3 a quarter - that was over summer, so will cost a bit more in winter. So solar is really something.

But then with the utilities and their buybacks, such efficient and clean ways to power our homes are made to appear "uneconomical".

I heard that China is making a lot of headways into solar and other alternative sources. Mainly because pretty much all the current sources of fossil fuel are occupied (liberated?) and their energy security requires alternatives so the comrades are really backing it.

Compare that to the US and most Western countries - Canada and Australia being closely linked to the fossil economies... we're lagging in these clean innovation. Not from the lack of skills, just the lack of political will.

Induction charging is a form of wireless transfer... it's being used on the new trams for Sydney. So no overhead cables... and predestrian won't get electrocuted if they step on it either :xyxthumbs

What percentage of the power is lost into the environment, is it more efficient than an over head wire? or just more "sexy"

A lot of the examples I have seen lose a lot of energy, a bit like shining a spot light onto a solar powered device to run it, eg a lot of the energy misses the receiver and only a certain percentage of the energy that does hit the receiver is converted into electrical current.

Don't know the % lost. I'd imagine it couldn't be much since the charging/receiving are right next to each other and only activates along with the tram. But I'm no electrical engineer - just your typical connect red to red kinda guy.

A very good text on this "The Intuitive Edge" shows clearly that we communicated via brain waves prior to language.

Ever noticed a flock of a hundred small birds in flight change direction together instantly. Yep all tuned into the lead bird. Many clear scientific tests in this text.
