A system for harnessing solar energy using heating applications to generate intense heat for steam boilers and all other water heating applications. Electricity is generated using a steam turbine engine that employs a bank of four biconvex octave lenses, with each having specific sizes, radii, arc convexity and distances from one another in mathematical orderliness in compliance with the Geometry of Space and the Law of Octave of Elements of Matter. The focal points of these lenses are positioned onto a boiler tank consisting of a pair of flat steel sheets in which water runs through from one side and comes out as steam on the other side of it. The steam is then fed into a steam turbine engine to generate electricity. A dual axle sun tracker is adjusted beneath the boiler plate to track the sun's movement from both east to west and north to south at all times. A system of highly conductive carbon rods is assembled on top of the Tasoptic lenses to be activated and subsequently produce an intense arc of hot white light to simulate the sun's parallel rays during the night and cloudy days for the continuity of operation at all times.

An ambitious plan to power every property on SA's Eyre Peninsula with solar has been labelled an Australian first but is it too good to be true?

Australia's largest integrated battery and solar farm in Victoria's north can power 16,000 homes. It was officially opened today.

South Australia's energy needs have been given another boost, with a new solar thermal plant to be built in Port Augusta. The SA Premier says the 150MW facility will provide all of the State Government's power needs, and will also generate hundreds of jobs. The Mayor of Port Augusta says it's a historic day for the city, still reeling after the coal-fired power station closed last year.

The Government believes the projects will create more than 600 jobs and generate enough clean energy to power more than 80,000 homes, while farmers have labelled the decision as "gutless".

A solar car competing in the World Solar Challenge has rolled over on the Stuart Highway, just north of Coober Pedy in South Australia. The driver has been released from hospital.

The leading car at the World Solar Challenge bursts into flames and is forced out of the race just south of Port Augusta. It follows three cars being blown off the road yesterday in strong winds.

(United States Ninth Circuit) - Affirming the district court's dismissal of a shareholder derivative action for failure to show demand futility in a suit where shareholders of a company who brought suit for breach of fiduciary duties for failing to disclose manufacturing and design defects in the company's solar panels without making a demand to the board.

(United States Ninth Circuit) - In an antitrust lawsuit alleging a power district had attempted to entrench its monopoly by setting prices that disfavored solar-power providers, defendant's appeal of the district court order denying its motion to dismiss the suit based on the state-action immunity doctrine, is dismissed for lack of jurisdiction where the collateral order doctrine does not allow an immediate appeal of an order denying a dismissal motion based on state-action immunity.

(United States Ninth Circuit) - Affirmed. Plaintiff filed suit against the Commissioners of the California Public Utilities commission alleging that the California Renewable Market Adjust Tariff (Re-MAT) program violated the Public Utility Regulatory Policies Act (PURPA). The district court granted summary judgment in favor of the Plaintiff, but declined to grant Plaintiff a contract with PG&E at a specified price. The Ninth Circuit held that the Re-MAT program violated the PURPA and therefore is preempted by PURPA, but the Ninth Circuit would not grant the contract because PG&E was not a party to the suit.

(United States Federal Circuit) - Affirming the US Court of International Trade's decision sustaining the International Trade Commission's finding that Chinese imports of crystalline silicon photovoltaic cells and modules were being dumped on the US market, damaging domestic industry, because these determinations were supported by substantial evidence on the record.

(United States Federal Circuit) - Appeal from US Court of International Trade (ITC). Plaintiffs sought preliminary injunction to bar enforcement of Presidentially imposed tariff. ITC denied preliminary injunction and appeals court affirmed. The President has authority under Section 201 of the Trade Act of 1974 to impose tariffs and where a statute authorizes a Presidential determination, courts have no authority to look behind that determination to see if it is support by the record.
