Melbourne’s Bay Bridge - Weather in Melbourne very favourable.

The worlds most livable city Melbourne has ideal weather everyday all year for construction of a Bay Bridge and collecting toll revenues; or generating tide current hydro. It’s true that New York, USA has tide current hydro by Verdant Hydro and that they say “There’s no city like it.” But, really Melbournes’ weather allows us to lead the world.

So; these tide hydro units are very low RPM as low as 7 RPM and quite unlike the propulsion systems under large container ships, submarines or cruise liners. Douglas Adams (above post) talks about sonic base sound as inaudible and audible to the human ear. I would think boats, ships and wind propellers were more significant and aggressive propulsion systems for noise. It’s easily tested and proven.

Melbourne’s Bay Bridge - Hydropower.

https://en.m.wikipedia.org/wiki/Hydropower

In 1895 Launceston was Australia’s first city to use hydroelectricity from the South Esk river. Today’s population is now approaching 85,000. A MBBridge would service directly a five times greater group of registered road vehicles. MBBridge Hydro has an equally larger electricity market.

Quote:
The power station was built on the South Esk River six kilometres west of Launceston city.
Completed in 1895, it was the first commercial hydro electric station to be commissioned in Australia, built to light the city streets.
It initially supplied direct current for arc lamps and alternating current for incandescent lighting and electric motors.
By 1921 it had been converted to three phase alternating current, and its capacity was expanded to 2000 kilowatts.
In 1929, Launceston's biggest flood on record partially destroyed the building, as water entered the site and removed part of the river side wall.
The council continued to operate the station until 1956, and maintains ownership of the site.

Now Launceston is planning an East West Bridge reports Carley Dolan on 14 Jan.2018 in The Examiner.
Quote:
The jewel in the crown of a $92.5 million traffic vision for Launceston will be a new bridge connecting the East and West Tamar highways, from Riverside to Newnham – something that has been talked about for decades.

http://www.examiner.com.au/story/5165095/liberals-promise-new-bridge-connecting-east-and-west-tamar-highways-if-re-elected/

Quote:
Mr Gutwein said the exact location of the bridge and the road exiting the West Tamar Highway would be decided during the planning and design stage.

“The funding for the feasibility, design and geo-tech studies is in the budget and available immediately as well for the bridge at University Way,” he said.

“And we’ve included within the five-year window $25 million as the first state contribution to that project, subject to planning determining that it should go ahead and whilst we’re working to that process, we’ll put together a submission to Infrastructure Australia - we’ll need to seek some Commonwealth government support for this.”

Melbourne’s Bay Bridge - $160m. in a day. Tide Hydro units @530 MW’s.

Is it worth installing Tide Hydro Units in; or alongside MBBridge piers? Scotland’s Meygen project is building 400 MW’s; so if we did we could be the worlds biggest and best. Why? Because Victoria owns a unique ‘hour glass’ shaped Bay with a narrow neck that focuses the Riptide Current. For that reason it’s proposed shortest construction is 3kms inside the Heads on the Portsea side and 5kms inside at Bellarine Hwy., Queenscliff. So; there the current against the piers would be manageable. Hydro units being maintained with built in gantry cranes.

http://reneweconomy.com.au/australia-led-tidal-energy-project-sets-new-production-records-29054/
(Not that you’d earn $160 million everyday: but if you did? ANS: $58,400,000,000. income p.a.)
Not to be sneezed at! Worth a Case Study? A Feasibility Study?

Then there’s vehicle tolls at only $10 per trip. That’s also, $1,400,000 a week in tolls; or $72,800,000 income p.a. on 10hrs a day traffic flow. ( see p.107 National economic benefit ).

Today’s quote is from:
http://reneweconomy.com.au/coal-unit-trips-in-heatwave-as-tesla-big-battery-cashes-in-85623/
Quote:
But Thursday’s unexplained outage of Loy Yang B caused the near instant loss of 530MW of capacity, and sent prices soaring in Victoria (to more than $12,900MWh) and South Australia, to a peak of $14,600/MWh.

Analysts at the Energy Transition Hub in Melbourne estimate this added $160 million to the cost of wholesale electricity. Prices jumped to a lesser extent in NSW, Queensland, and Tasmania.

The failure will be if particular concern to AEMO, which has already warned on repeated occasions that the biggest danger to grid supplies is the unexpected failure of a large fossil fuel generator, now a regular occurrence in extreme heat.

It comes as a heatwave is expected to grip South Australia, Victoria, Tasmania and parts of NSW over the coming four days, and amid forecasts for increasing temperatures in future years.

Wind and solar may vary their output according to weather conditions and the time of day, but these shifts are largely predictable.

It is the intermittency of the big coal generators, and their sudden and unexpected outages, that causes the biggest headaches for market operators, along with events such as storm damage and bushfires.

Water energy density 832 times that of wind. Tide current hydro 24/7 except ebb tide.
Silent and out of sight. Practically invisible. :mrgreen:

How much is Australia’s National Energy Market worth?

Name another bridge anywhere with a better annual income that’s cash flow positive!

Melbourne’s Bay Bridge - Mud Island.

Image

If. I say if, the currents are too strong to build MBBridge piers; then how is mud island continue to exist inside Port Phillip Bay back from The Heads?

Melbourne’s Bay Bridge - What’s it cost?

• Revenue from Hydro generation.

• Security of reliable regular power.

• Synergies from efficiency of Transport.

• Revenue from tolls for higher volumes of traffic than the ferries can handle.

• Time saved in a 10 minutes link verses by ferries.

Just as Westgate Bridge did for Melbourne’s CBD in 1978, by opening up efficiency and opportunity: so too; will Melbourne’s Bay Bridge expand and improve our lives.

• What’s it cost? We all loose by not doing it. MBBridge is an immediate win for jobs, employment and skills development. How much it costs to put in place is the wrong question.

• What does it cost us to delay this Planning Approval and open it up to tender? That’s the big question!
