That was a pretty tired old line about these things not being useful unless the sun shines or the wind blows. 

Even the ANGRY and CONFLICTED president of the...failing...USA said it. 

Sad.

Nobody in Trump's government at least, and I don't think the prior government, could envisage pumping water uphill.

Hey LogicaL Chaos yes I agree and think it's very cool too. I'd be hopeful the powerline is connected along the existing corridor.

Hey JohnRainy, for sure, point taken. It's just my opinion but I feel the aim of the 'infomercial' using term's like that, the guy in the lounge chair, the line about jobs etc, was to keep it short and sweet and dumbed down.

This from the Queensland government
"In the absence of a Federal energy policy, Queensland is once again doing the heavy lifting by backing projects like Genex at Kidston.”

The message needs to be kept simple and the dollars need to add up, because as you can imagine, it's a political hot potato.

"atmospheric electricity" is interesting..




in 1996 an experiment hanging a wire from a satellite,
which collected atmosphere ions as it moves in orbit,
immediately collected 3500 volts, burned threw tether,
snapped, and floated away in space, experiment over.

I build wind turbines for a living. I like wind. It's the cheapest way to make power. It works, it's economical in today's market without tax credits.

Very cool! Ive heard of static electricity harvesters! Ive also seen an article about a device that harvests radio signals for power such as this article: http://www.sci-news.com/physics/battery-free-cellphone-05042.html practically free energy!

Ahab, yes wind power is legit and has proven effective for years. :yesnod: Ive been to North Oregon and there are HUGE wind farms. Not only spanning large distances but the turbines themselves are gigantic! Its incredible how big they are. I once saw a semi transport just one side of the propeller and it took up the whole bed. Blew my mind.

:smile: That's interesting that you build wind turbines Ahab, I install solar, off grid and grid connected.
Last time I did the sums on small scale wind, say for a single residential load, the cost for wind v solar was 3 times as much.
The extra costs were in the ground work.
From memory the base of the mast for the turbine needed 8 cubic mtrs of concrete and the winch anchor point(to raise the mast) needed another cube.
To do the same work as a 4kw solar system I worked out we needed a 5mtr diameter turbine, 10 mtrs in the air.
I'd be interested in the $$ comparison of those big ones though as large scale solar gets expensive.

Over 20% of Aus households now have  a solar system on the roof. Solar is fine, batteries are the problem.
We have been doing grid connected batteries but they are a shit load of work.. in my opinion we need say a 1 megawatt battery where the largest low voltage/high voltage transformers are in the suburbs, it would save a lot of fucking around.

Wind works poorly for small scale. It works best on industrial scales because wind is better the higher you go and the bigger the rotor is. Most of the models I work on are at hub heights above 100meters, 3.0+MW nameplate value and have service lifts in them. I think the ones here have 350m3 of concrete for the bases, and that is really small due to a new engineering design. Older ones have just tons and tons of concrete in the bases.

I'm not sure you want a couple of tons of lithium next to houses. Batteries get really hot and fail on occasion. If that sucker lights up, it's going to burn for a week, you can't put water on it and it will burn down the whole neighbourhood. Suburb property is usually more valuable than an industrial lot covered in crushed rock you could dump a couple of shipping containers filled with battery banks.

That's a bloody good point :thumbup: and sort of similar to my view that we don't really need 2 million potential battery bombs, in various states of neglect, across the 'burbs here.

3 megawatt that's decent. I'd like to watch the concrete pour on one of those bases, it'd be a procession of concrete trucks.

I think it's like 20 concrete trucks per foundation. I'm not sure though. We don't have much to do with earth works.

Awesome.

How long did it take? How many workers does it take? 3.6 megawatts is freaking huge! Didn't know they were that efficient :omgz:

I'm sure that a good many of the magnet motors on YouTube are bunk, but there are real scientists working in this area.

Vladimir Roshchin and Serge Godin invented a Magentic Energy Converter that is similar to the Searl generator. These machines show overunity when operated at a high rpm. In both cases the machines lower the ambient air temperature which indicates that they are collecting energy from the heat in the air. So the machines should run until the environment is at absolute zero.

I think the best source of energy is not an alternative, but nuclear. Nuclear power generation produces no carbon emissions, is very feasible, produces as waste only low-level products that can easily and safely be dealt with, and is hugely efficient. Despite Fukushima, which was mismanaged and an generated an avoidable meltdown, it can be done safely and properly if done right. I think the biggest aversion to it for the masses is fear of the word "nuclear," which frightens people. This is by far the best way to make the power grid "green."



Only issue with nuclear is waste. They can recharge the uranium core these days. Just in thousand years their will be no waste.

Yeah nuclear waste is definitely one of the biggest downsides of nuclear power.

Yes, nuclear produces waste, but it's still much, much cleaner and safer than coal or oil burning. It's the only viable way to become carbon neutral, if we have any interest in actually doing that.

There is not that much of it. All of the used fuel ever produced by the commercial nuclear industry since the late 1950s would cover a football field to a depth of less than 10 yards. That might seem like a lot, but coal plants generate that same amount of waste every hour.

The U.S. nuclear energy industry has safely transported used fuel without any harmful release of radioactivity, injuries or environmental damage. In fact, after 7,000 shipments total of used fuel by the worldwide nuclear industry since 1970, there have been no leaks of radioactive material or personal injuries.

Thankfully coal is coming closer to being a dead industry every year. The availability and low price of natural gas is the biggest reason.

The biggest barriers to alternative energy sources is oil money lobbying against it.

Thats a wild fact!

When i think about it, theres never been a radioactive leak from transporting the fuel that i can remember. Very interesting.

Brain, theres definitely a political aspect to it. Its also spendy to get these types of alternative energy sources going, so there has to be a "proven" cost-efficiency relationship. As with all experimental technologies, it can take awhile to gain mass support from all industries. But oil is big business. Its a huge industry, not just fuels either.

Naturally. You know what they say: "Shell powers the Sun." If it weren't for big oil, we'd probably have gotten into all sorts of higher tech stuff as far back as the 80s or 90s. But of course, money was withheld from such endeavors -- by the oil companies. As soon as new patents for things come up, Exxon buys them. Otherwise there would have been all sorts of money pouring into alternatives. Alas, we live in an extremely corrupt world.
