I have been pondering the use of solar cells, wind generators and tidal generators for some time; each renewable energy source usually fails to produce sufficient energy when and where it’s needed. How can we store the energy produced when it’s in plentiful supply and use it later in peak demand time. The often rolled out solution is to pump water into a dam and use the stored water to generate electricity, this is known as pumped-storage electricity and accounts for 99% of bulk storage at the time of writing. This method assumes a lot of water is available which may not be true in Australia’s arid and semi-arid environment. Small renewable energy generators use batteries for base-line storage, but this is expensive and high maintenance.

The about face by the Gillard Government over the so called Pacific Solution for processing alleged refugees, AKA boat people, has seen the expectations of Manus Island and Nauru residents rise. Manus Island has demanded that their businesses, fishermen, farmers and labour be used instead of the imports that were used last time. This is not an unreasonable request and is probably a cheaper solution if done competently. Of course we have not taken into consideration the complete ineptitude of the Gillard Government who have proved over and over again that they can’t even organise a piss-up in a brewery.

“Successful investing is anticipating the anticipations of others.”The people that buy stock as a long term investment expect to receive a reasonable dividend every year and for the value of their investment to increase over the years. The investor will also realise when a company is in decline and divest themselves of the shares before the company share price drops.

One of the popular beers at the moment, especially among women, is the low-carb beer which is widely believed to be a healthier beer than normal beers. These beers often command a premium price and are widely advertised by brewers. Is low-carb beer really better for you or is it just an urban myth?

There is some contention in Australia over what is exactly a ‘free range’ chicken. The US has decided to avoid the issue by ignoring labelling standards altogether. The EU (European Union) with all of its bureaucracy has defined four labels: 0-organic, 1-free range, 2-barn and 3-caged.
