Some innovations need system integrators and coordination

Much innovation occurs by incremental improvements in technology. Jet engines gradually replaced piston engines in the aircraft industry. Cathode ray tube television sets have been replaced by flat screen televisions.

Other innovations are not so easily made by incremental adoption. A vehicle manufacture developing the first model able to be fueled by unleaded petrol would have difficulty finding a customer if no petrol station sold unleaded petrol. A petrol station proprietor would be unlikely to stock unleaded petrol when no customers drove vehicles needing unleaded petrol and no oil refinery made unleaded petrol....

Innovations are often disruptive and the benefits come with adverse effects ...



Many innovations only work when they are part of a collection of co-ordinated changes that are adopted across a number of industry participants.

The components needed to make some innovations work may exist in other fields. Industry participants and product developers can benefit from the skills of  system integrators to locate components for a viable design made up from a collection of products that will work well together.

The technology capabilities of The Royal Society for the Protection of Birds, "Tracking seabirds to inform conservation of the marine environment" suggests a way to overcome the quite real concern of the Federal Government that electric cars will hit its bottom line by driving a fall in fuel excise revenue.
Advances in the miniaturisation and mass-production of low-cost, lightweight, high-precision GPS tags, enables tracking the detailed movements of large numbers of seabirds, including some of the smaller species.

"The Turnbull Government is preparing to drive a new debate over how roads are funded in Australia, with the revenue collected from fuel excise expected to shrink in coming years. Right now motorists pay almost 40 cents a litre in tax, delivering close to a $11 billion dollars a year to the Treasury." (@ABCNews, 16 August 2016)

The existing fuel excise that funds roads is raised in proportion to the amount of fuel motorists buy. Motorists who drive only during off-peak times on regional roads pay at the same rate as motorists driving on expressways in cities during peak periods. A replacement technology that can measure the time, distance and location of trips may be sold on the basis that it is more equitable than the existing fuel levy that contributes to road funding.

Mass production of batteries for electric vehicles will drive a significant reduction in their manufacturing cost.

There is an opportunity to combine this predictable reduction in the cost of lithium-ion battery energy storage with the continuing decline in the price of solar photovoltaic (solar PV) systems.

The two technologies don't immediately work well together when people typically drive to work early in the morning and return home late in the day. Any solar energy generated at their home during the day cannot be conveniently used to recharge their electric vehicle.

An option to improve the overall performance and cost-effectiveness of these technologies has been developed ....

This technology makes an electric vehicle's battery pack an interchangeable unit: "6 Reasons Tesla's Battery Swapping Could Take It To a Better Place."

Having an electric vehicle battery at home being recharged during the day allows energy in the battery to be partly discharged at times when spikes in the energy demand exceeds the output of the solar PV system, such as an air-conditioning turning on for 20 - 30 minutes late in the afternoon to cool the home before the residents begin returning from school and work.

Dairy industry hit by mysterious crisis

Dairy Australia collects production and sales information for the industry.

Dairy Australia's information shows no surprising change in production or in demand.

Among the noteworthy changes are:
  • A 21.4 % annual increase in the volume of milk exports.  There was a corresponding increase of 19.7 % in the value of these exports from last year (July 2014 -  June 2015) to this year (July 2015 - June 2016).  
  • A 63.4 % annual increase in the value of whole milk powder exports.  This increased value was obtained with just a 2.4 % increase in the volume of these exports from last year (July 2014 -  June 2015) to this year (July 2015 - June 2016). 





Milk production (millions of litres)

Production fell slightly in 2015/16. A collapse in price can't be explained by an increasing supply.

The Liberal Party "Jobs and Growth" Plan according to Treasury

Appearing on the Q & A program on ABCTV on 21 June 2016, PM Malcolm Turnbull gave the answer below to this question -

JAQUELINE: Mr Turnbull, your jobs and growth mantra is based on the trickle-down economics theory. Your former employer Goldman Sachs and many other trusted sources have raised serious concerns about this tax cuts and confirmed that a significant proportion of the windfall will benefit overseas investors, shareholders and not trickle down at all. Over 10 years the plan will cost the Australian taxpayer in the vicinity of $50 billion. Why should ordinary Australians support cuts to our services to give companies a tax cut that according to so many experts probably won't create jobs or contribute to growth significantly and elsewhere has been shown to increase inequality in society?
Malcolm Turnbull with Terry Jones on Q and A

Malcolm Turnbull: Well Jaqueline thank you. Firstly let me say that cutting company tax does not increase inequality in society. There has been a long trend towards reducing company tax right around the world. The biggest cutter of company tax in our lifetimes is in fact Paul Keating, who cut company tax twice and he cut it because he knew that if you reduced company tax, if you reduced business tax, you increase the return on investment. If you increased the return on investment, you get more investment. If you get more investment, you get more employment and you get more growth. That's why the Treasury found last year that for every dollar cut in company tax, you got $4 of benefit of growth into the economy, into GDP of which between two-thirds and three quarters went to labour, went to workers
Treasury produced a report on 3 May this year "Analysis of the long term effects of a company tax cut" that models the two options for funding the planned company tax cut.

While Malcolm Turnbull said "Firstly let me say that cutting company tax does not increase inequality in society", the Treasury modelling of his "jobs and growth" plan says the exact opposite -

4.  COMPANY INCOME TAX CUT FINANCED BY A PERSONAL INCOME TAX INCREASE

In this section a reduction in company tax rate from 30 to 25 per cent is financed by an increase in the average rate of personal income tax.

Theory and key assumptions

The personal income tax system includes the taxation of both labour and capital income. It is difficult to incorporate progressivity in a model with a single representative household, so the modelling reported here assumes a single effective tax rate (hereafter average personal income tax) that is applied to labour income and capital income after franking credits. Progressivity potentially raises the excess burden of a tax, which implies the modelled average personal income tax increase may understate the welfare cost of raising revenue via the actual personal income tax system. As noted in Section 3, the perfect capital market and fixed domestic saving rate assumptions imply the capital income component of the personal income is largely invariant to changes in personal tax rates.  Therefore, the distortionary part of the modelled personal income tax is effectively the labour income tax component.

5.  COMPANY TAX CUT FINANCED BY A GOVERNMENT SPENDING CUT

In this section a reduction in the company tax rate from 30 to 25 per cent is financed by a cut to government spending.

Theory and key assumptions

Government spending is assumed not to affect directly the welfare of households. In the previous two scenarios real government spending was held constant so adding it to the household utility function would not have made any difference to the welfare calculations reported there. In the current scenario, the implicit assumption is that all government spending that is cut is wasteful. While this is a common modelling assumption it ignores the fact that: government spending provides goods and services [Medicare bulk-billing for instance] that would otherwise not be provided by the market sector; households derive direct utility from government spending; and infrastructure spending can improve market sector productivity. This suggests the model will overstate the benefits of this funding alternative. This scenario is expected to yield significantly higher welfare gains than the previous two scenarios because an additional assumed distortion is removed from the economy.

Taxpayer dollars create state-owned bank to build coal-fired power stations

The Coalition Government has used taxpayer funds to create a state-owned bank that is to finance new coal-fired power plants in developing countries.

This will help to increase demand for coal for new mines for decades.

Media Release by Treasurer Joe Hockey, 24 June 2015

Australia to join the Asian Infrastructure Investment Bank

"Joining the AIIB presents Australia with great opportunities to work with our neighbours and largest trading partner to drive economic growth and jobs [or JOBS and GROWTH].
...
Australia will contribute around A$930 million as paid-in capital to the AIIB over five years and will be the sixth largest shareholder."

LNP 'fix' for a revenue problem it says doesn't exist

Scott Morrison delivered his first and perhaps final budget as Australian Treasurer in the last days of the Abbott/Turnbull Government.
  • The 2016-17 Budget was presented by the Treasurer, Scott Morrison in the House of Representatives on Tuesday, 3 May 2016.
  • The 44th Parliament was dissolved a few days later on Monday, 9 May 2016 at the request of PM Malcolm Turnbull.

Scott Morrison consistently says the Government doesn't have a revenue problem.
"Mr Morrison rejected suggestions there was a problem with money coming in, saying revenue as a share of the economy would be higher than the long-run average next financial year." (SBS News, 8 April 2016)
The budget summary in his budget does in fact show revenue as a share of the economy being higher than the long-run average next financial year.

The same summary however shows tax revenue as a share of the economy being higher than the long-run average not just next financial year but in every following financial year. The share actually increases in every financial year to 2019-20, remaining well above the long-run average.

Converting coal fired power stations to solar thermal chemical fuel

The Yallourn Power Station and the Hazelwood Power Station in Victoria are two of the most inefficient and CO2-intensive power stations in the world.

Hybrid solar-fossil systems for large-­scale solar energy storage

Michael Dolan & Daniel Roberts, University of Adelaide, February 7, 2013

Highly endothermic gasification and reforming processes offer a significant opportunity for the penetration of Concentrated Solar Power into the chemical and fossil energy industries. The upgraded products incorporate solar energy in chemical form which enables the ready storage, distribution and use of concentrated solar thermal energy.

Yallourn

The Yallourn Power Station produces about 22 percent of the electricity used in Victoria. Every hour 2,400 tonnes of brown coal are needed to produce super-heated steam for 4 turbines. These turbines have a combined capacity of  1,480 megawatts of electricity. In 2015 annual generated electricity output was 10,256 GWh, up from 9,806 GWh the year before.

In 2015 Yallourn Power Station installed a new High Pressure- Intermediate Pressure (HIP) turbine in Unit 2. This resulted in an efficiency improvement for Unit 2 of around 2.7%. This marked the completion of a 5 year program of new HIPs on all four Yallourn Units.

Hazelwood

The Hazelwood Power Station produces up to 25 percent of the electricity used in Victoria. Up to 15.3 million tonnes of brown coal are needed each year for an annual generated electricity output of approximately 12,000 GWh. Steam from 8 water tube boilers drives 4 turbine stages. These turbine stages have a combined capacity of  1,542 megawatts of electricity, just 62 megawatts more than the Yallourn Power Station.

Since 1996 more than $1 billion has been invested at Hazelwood to improve efficiency and reliability.

Lignite or brown coal from the Hazelwood mine is about 62 percent moisture at extraction.

Efficiency and CO2 Intensity

The brown coal used as fuel supplies about 9 gigajoules of thermal energy per tonne. The coal-fired power stations convert about 24 percent of this energy into electricity. The other 76 percent is output as waste heat.

Each tonne of brown coal contains about 250 kilograms of carbon and the balance, 750 kilograms, is mostly hydrogen and oxygen.

When burned the hydrogen and oxygen is converted to water vapour, while the 250 kilograms of carbon combines with oxyygen from the air to form 920 kilograms of carbon dioxide.

To generate 1 megawatt-hour of electricity at 24 percent efficiency, 1.667 tonnes of coal must be burned. This contains 417 kilograms of carbon that is converted to 1,528 kilograms of carbon dioxide when burned.

Solar Thermal Fuel in a Converted Coal Power Station

Brown coal can be converted into a mixture of gases using concentrated solar thermal energy.

One such process could convert each tonne of brown coal into 920 kilograms of carbon dioxide and 80 kilograms of hydrogen.
Solar thermal gasification of brown coal
Solar thermal gasification of brown coal

The 80 kilograms of hydrogen gas from each tonne of coal supplies 9.67 gigajoules of thermal energy when burned.

This hydrogen fuel could be burned in one or more gas turbines added to an existing coal fired power station.

The hot exhaust gas from these gas turbines would be used to create superheated steam in the coal fired power station's existing boilers and drive some or all of its existing steam turbines.

The addition of the gas turbines fueled by hydrogen can raise the efficiency of the power station from just 24 percent to 60 percent.

The thermal energy available from the 80 kilograms of hydrogen fuel consists of the 9 gigajoules present in each tonne of pulverised coal together with 0.67 gigajoules of solar thermal energy.

At 60 percent efficiency this 9.67 gigajoules of thermal energy is converted into 5.8 gigajoules of electricity.

To generate 1 megawatt-hour of electricity at 60 percent efficiency, only 0.62 tonnes of coal must be converted to hydrogen that is burned.

This amount of brown coal contains 155 kilograms of carbon that is converted to 570 kilograms of carbon dioxide when it is gasified using concentrated solar thermal energy.

The hydrogen, 50 kilograms, from the 0.62 tonnes of brown coal is all that is required to generate 1 megawatt-hour of electricity.

There is a saving in mining operations because much less coal needs to be processed for each megawatt-hour of electricity generated: a reduction from 1.667 tonnes to just 0.62 tonnes of coal.
