Technology Advances With the Scramjet

Technology: Scramjet is tested at Woomera.
Technology never stands still. Mankind progressed very slowly for centuries, but now things move forward at a rapid pace. Air transport could change dramatically in coming decades. The US and Australia are testing a hypersonic rocket that can travel at five times the speed of sound. Because of the angle of liftoff, together with takeoff and landing speeds, you couldn't really enjoy a lunch and drink while sitting in your seat.
Scramjet test at Woomera
Woomera in South Australia is the busy testing site. The project is not aimed at space flight. Passenger travel is the main goal. A journey from London to Sydney is estimated to take two hours. The arduous passage though would mean taking your meal preferably after the flight.

Australia helped develop the scramjet which uses oxygen from the atmosphere for power as the jet rockets upward. Consequently, it does not have to carry heavy and expensive fuel. Tests began in 2009. Norway and Germany are also involved in the project. The target completion date is in 2018.

Big Raves About the Pegasus Helicopter Flotation Device

Technology:
It is surprising how people and government bodies live with a problem for decades when the answer is in front of their noses. Quite frequently rescue helicopter crash into the sea. There is usually a "ho-hum" - another helicopter has fallen from the sky.

Helicopters that can take off and land in the sea have been around for years. It is old technology. Obviously rescue organizations could have used them. However, they seem to feel that it best to reinvent the wheel. They plan to modify existing helicopters.

A self-inflating buoyancy balloon will be attached to standard helicopters. When a sensor detects water, automatic inflation will occur. Australian defence is throwing $4 million at the project. Marise Payne the Defence Minister is lauding it, saying "this is a fabulous innovation, by Australian minds, Australian brains, Australian workers...."  Let us hope it is not just a silly idea!rafdevice

Private Health Insurance Fiasco in Australia

The government intends to ruin Australia's private medical insurance system. With privatization Medibank Private Health Insurance will become like all the other funds. The Commonwealth bank was once owned by the government  It is now just another bank.

At the moment Medibank has two "branches". One (Medicare) refunds part of the fee charged by specialists, blood tests and various bills from hospitals. The other is a private health insurance fund. There is a problem here, however. Medibank and Medibank Private are both registered names held by the federal government. How can a public company and a private company use the same business name?

One of these will have to change its name. People are being offered shares in Medibank Private. How long can this be allowed to continue? Isn't it illegal? Future shareholders must be told what will be done about this. A change in name will have a disastrous affect on the value of shares.

There is no doubt that Medibank Private is subsidized by government. Share values will fall as it becomes just another private fund. Surely investors can see this - maybe they are too thick to understand.  Medicare, Medibank:  what's the difference?
