He dispatched it with the Booligal Flick [During the Booligal Rabbit plague of 1896, boundary riders would ride up on the rabbits swing down, grab the hind legs and flick them like a stockwhip despatching them instantly.] Seeing Cappy in his uniform He yelled "You XXXX!, get them back in order!" Campy whimpered "I'm trying, I'm trying, don't pick on me", but the cabin was full of fur (most unusual for Cappy), and Turbo had to go back to the control seat and radio: "Houston we have a problem" At the control centre in Houston a siren started blaring and people came running from the coffee shops and relaxation gyms to the Control Centre. Almost at the speed of light, engineers appeared with plastic bottles, Kentucky Fried barrels and lengths of plastic pipe ready to solve any problems. "Go Ahead" said the controller and there was the swishing radio sh!t you hear from space and Turbo yelled "there are 2,000 rabbit choking us.........and before he could go on the Controller said to the engineers "Quick, get some rabbits!" and ..........

Finally the day approached when Turbo himself was to make the trip himself into space in the Rabbit-Turbine Special.

As the world knows Dick Branson faked his bike ride to his space ship, and the PR fell flat,something Cappy knows only too well, so Turbo didn't have to do that pathetic stunt ad arrived at the launch pad in much better condition. 

The Bunny-Master was Cappy, who was wearing a brown band-masters uniform with gold braid and twirling a blunderbuss. Every rabbit eye was fixed firmly on him and when he gave the signal to enter the space ship, after Turbo of course, every rabbit marched neatly in step up the steps.

The take off was routine, but when they arrived at the outer ring, the aur was filled with ....................bunnies. No one had made an allowance for 2,000 floating bunnies, and Turbo started to choke and yell for Cappy who was doubling as a Hostess for the flight, and ..................

Older NES readers will note from the above workshop, the Fast Moving Part which was the biggest volume seller Repco every Retailed.

Not many people know that Joseph Lucas was a comedian with a quirky sense of humour that saw men achieve greatness in business to the point at which they were earning enough to buy a Jaguar at which point they came in contact with Sir William Lyons who started Jaguar, but who was also a comedian, and his longest running joke was not only putting one of Joe Lucases fuel pumps, the forerunner of the fart cushion, into the new Jaguar but locating it in the front of the boot, so that when, late at night on a long holiday trip, the inevitable happened and the contacts burnt out, the driver had to unload the wife's suitcases in the rain. Pity help him if had also forgotten to bring his Part No 530433 (they all knew the P/N by heart.)

That's misleading; I'm surprised you would say that.

In any cost model, the Prime Cost must be included, which is the thousands of dollars paid for the equipment, and the installation, less any government subsidy. For many people, who have to pay contractors or get sucked into the "No Cost Solar "deals" they will be into the maintenance and replacement phase before there is any return, then the costs start again.

My own anecdotal enquiries of the occasional Qantas pilot is that CASA hasn’t had the technical ability to supervise a major airline for at least the last thirty or more years. One of them told me: “they asked questions and we fed them bullshyte answers till they went away”.

 

‘’However the more important question is whether CASA has more political clout than Qantas? I think not.

 

As for the AG Department, they know nothing about aviation. They can check the paper clip stock records and that’s as far as it will go.

The Auditor-General as his name implies is an auditor rather than a forensic Manager. 

I involved the Victorian Auditor-General in a road project which was suspect. He handled it by employing a specialist Consultant, the consultant drived most of his income from the State Government and apparently suffered an eyesight episode on the job (a bit like your paper clip stock records)

You also have to be careful of the stories like the Qantas one which comes from  prescriptive administration where obfuscation is an art form, and unless the obfuscators are caught, any disaster is the responsibility of whoever prescribes the rule or regulation. CASA does both prescriptive (as in CARS/Strict  Liability) the same as the road authorities and non prescriptive (which includes Self Administering Organisations) where they may set a recommended benchmark or outcome and it's the responsibility of the person or organisation to achieve the result, in which case feeding them bullshyte just results in them ensuring you understood the benchmark, then letting you hang yourself (in broad terms).

Another aspect of your EV concept Aro is that, with EV Sales at the 500,000 per year mark there would soon be enough sitting on chargers each night for software to do what you suggest, and pump back into the grid when energy was needed, but that leads to the personal scenario similar to driving home and parking your car with a trip planned/business/appointments the next day, and overnight your petrol tank is emptied or left half full.

Renewable energy is becoming cheaper very quickly. It has been reported that it is cheaper now to build new solar or wind than to operate coal power stations.

 

EVs can potentially help solve the problem of variability, because they have big batteries and can actually return power to the grid if there is a shortfall. With the right software, you could charge your EV when solar and wind are producing a lot of power, and sell the power back for a profit when the renewable energy supplies drop. Power companies obviously don't want that to happen - they want to make the profits themselves - but it just means that some planning and regulation might be required.

There's no doubt that renewables are way cheaper than power generated by coal-fired power stations, or that renewables can operate at full capacity all the time.

There's also no doubt that a steam turbine driven generator requires a boiler which must run continually to avoid structural damage, and can only be brought up to temperature slowly. Its this need to run at a base temperature to avoid boiler damage that is termed base power. In the past electricity companies would sell power "off-peak" at a greatly reduced price for things like hot water systems, but that never covered costs and in recent years, even if you buy a HWS with off-peak switching and wiring to the meter, you may not get a deal.

Because of this, In Base Power conditions, and up to a certain output, renewables can supply cheaper energy to the Eastern States Grid, which is based on short term buying and selling through AEMO, pretty much like a stock exchange. There are no favours given, electricity distributors will buy at the cheapest price they can get. So in recent years renewables have had higher market share in the winter months because the coal-fired plants, overfuelling because of the Base Load requirement can't compete, and this has led to power station owners withdrawing from the market and closing down. The downside to this result from free marketing is that renewables can't offer Peak Power volume to replace the former coal-fired capacity. That in turn is offset to a degree by the power companies buying energy interstate and from independent energy producers like the Sugar Mills in Queensland. On one hot night I was watching the AEMO dashboard and Victoria was pumping energy into South Australia to make up their shortfall, pulling energy from the Tasmanian Hydro, pulling energy from NSW, and NSW was keeping up by pulling energy from Queensland. On that night the total capacity of the renewables (solar and wind) was 1% of the grid.

That is the scale of the variability required.

The SA Big Battery has 40 minutes supply of the South Australian total demand, so sounds like a waste of time, but has proven invaluable when big energy demand comes on quickly, like a stinking hot day in SA, because the battery prevents some blackouts while the Coal-fired power stations are coming up to temperature, so they deifnitely have a future and are being expanded around Australia.

The problem with selling your power to the grid, EV or not, is the spot price system the Power distributors use to buy. You can watch it evolving on the AEMO dashboards, so if for some reason a power station in Queensland offers a cheap rate, you can see the price change and the energy flow change as distributors take up the offer. They are businesses and are unlikely to pay retail prices to homeowners with solar on the roof or energy stored in their EV which is pumped into the grid in minute quantities. You've alluded to this, but the States and Territories would have to be legally able, and then politically willing to set a minimim price paid to the household while there's also a free market.

Once built it is obviously untrue if renewable energy is used to charge the Teslas batteries.

We live in Australia, so the only State capable of achieving that is Tasmania with its hydro scheme.

While renewables hit a record 50% of the AEMO Eastern States grid this year in cool autumn weeks, and usually sit around 15 - 20%, on very hot days in 2020 and 2021, renewables could not achieve more that 1% of the grid capacity once the coal-fired stations started running at full boiler capacity. Renewables ahve already had nearly 40 years in Australia to show they can handle the spectrum from Base Load to Full Peak load but they haven't been able to deliver the goods WITHOUT EVs.

It was established during the last federal election when a lot of minds turned to Labor's policy of building half Australia's car needs as EV by 2030 that aside from things like not having a design or low volume manufacturing industry, the killer was not being able to supply the recharging power without building a second power station grid with a capacity equal to the present one. The Lead time for Nuclear, a viable Zero CO2 sourcem was so far out in the future, even if the public accepted it, that it had to be ruled out, so we were left with either gas-fired plants, which still emit some CO2, but have supply problems or coal-fired plants where as Geoff_H points out the new developments in ICE technology are going to eliminate EV as a viable alternative in terms of total CO2 emission.

General Motors recognised this achilles heel when they changed their Zero emission EV description to Zero Tailpipe Emission.

We live in Australia where there are no CO2 emission regulations for cars, so a lot of people are doing a lot of astroturfing while hoping for new inventions which will change the basics of physics.

But Turbo urea injection whilst reducing nox and co does nothing for pm10 or pm5 or co2 and can’t address the fundamental issue of using/releasing carbon from crude oil.

Turbs what are your thoughts on storing hydrogen as hydrogen  as a metal hydride or in ammonia or in many of the other ways it can be stored  Hydrogen storage?

 

 

Fortunately I don't have to waste my time speculating on alternative fuels. These things will be put forward by speculators, reviewed by engineers, and where promising become projects in the research departments, if still promising go into product analysis where costs and benefits are analysed in very fine detail, infrastructure analysis then takes place to see whether a viable support infrastructure can be adapted or built, and if still promising, product design engineers do the analysis to see how it can be incorporated into a car, aircraft, ship etc.

Around 2007 I was involved in checking out the viability of using urea injections downstream of the engine to neutralise exhaust emissions in long distance over the road trucks in Australia. I was able to show that with the on board tank storage available, I was able to show that there was infrastructure around Australia to refill the tanks with urea in all but two areas (from memory one of them was a let to Mt Isa), and for those legs, two containers would fit into the tool box. Even with competitive pricing and a readily available network, Urea Injecting dodn't make it to the top of the market, and is a minor player.

Yes an internal combustion engine with a very light tank.  Technology change less than fuel cells.  I think that passenger airline aircraft turbine engine would be simply modified to burn hydrogen.  Cryogenic tanks would be quite light, evaporation of fuel would be limited. The aircraft industry is so conservative I think that batteries or fuel cells and electrical motors are a change too far.

An A380 has 4 70MW engines, a significant amount of energy dissipation will require a significant technology change for electrical power.

True about the doable technology change.

Here's the thing, it's possible to build a lightweight cryogenic fuel tank, but that would be a hand grenade.

To make CNG vehicles safe required a tank with similar strength to an acetylene tank; in the words I was given when I asked what would happen in a collision "We've made the tank strong enough that in a T Bone it deforms the other vehicle."

If you could guarantee no forced landings or survivable crashes, you'd have to address that issue.

The people who are spruiking "Hydrogen" cars also have to deal with the same issue.

My personal opinion is that electric will never make it to aircraft.  I see hydrogen stored cryogenically as a smaller working solution.  Much lighter.  All hydrogen left in the tank after flight can be expected to be lost through evaporation.  I see hydrogen systems to fill tanks before and emptied after flight. Engines will require a limited amount of development.  The natural gas pipelines will be able to get the hydrogen to the airports.

I am worried about the flammability of hydrogen. When vented two dust particles colliding can ignites colourless gan with a flame front 10 times the velocity of natural gas. When you work on a hydrogen system you have to use brass tools to restrict spark generated.

When you say hydrogen, are you talking about a tank full of hydrogen being used as fuel in an Internal Combustion Engine as a lot of people are speculating about?

In that case the storage mass, combustion rate, power output are issues for discussion. What might just work in a vehicle might be too heavy for an aircraft.

If you are talking about a hydrogen fuel cell with an electric motor powering the prop, then cost and range could prove an issue.

Now Turbo, who had noted in his regular meetings with Xi that Xi didn't wash his hair and had dandruff, had asked Professor Lock from Turbine Surveillance LLC to make a camera the size of a piece of dandruff, and had pretended to scratch his head while flicking the camera into the hair of the President, heard all this at his condo on Cinq Terre where he was entertaining, and sent a text to OT suggesting he put in a Tender for Training and Operations of the Wing in the Chinese Navy.
