Comments Off on Spectacular ‘Dome of Visions’ greenhouse pushes the envelope for wood construction

Finnish company Metsä Wood is known for pushing the envelope when it comes to building with wood. Their latest greenhouse dome is the largest to date – and it showcases the company’s innovative use of laminated veneer lumber as a sustainable alternative to commonly used building materials. The structure, named Dome of Visions, was designed by Atelier Kristoffer Tejlgaard  as a way to explore green building. The Dome of Visions 3.0 is the third project in a series of experiments that explore the idea of creating sustainable spaces within dome-shaped structures. It has a new system of curved wooden beams , composed of 21 mm strips of Kerto LVL (Laminated Veneer Lumber). This made it possible to minimize the amount of steel while achieving both a sleek and elegant grid construction.

The custom-made Kerto beams made it possible to avoid the use of complicated and costly welded brackets used in previous versions.

In principle, wood is a material that comes from a solar-powered factory,” said Kristoffer Tejlgaard, referring to the ability of trees to extract CO2 from the atmosphere and store it as carbon in their trunks, solely by means of solar energy . + Atelier Kristoffer Tejlgaard + Metsä Wood

Comments Off on South Australia to build world’s biggest single-tower solar thermal plant

South Australia is going big again — as in world-beating big. Last month the state government signed a deal with Tesla to build the world’s largest lithium-ion battery storage facility. Now State Premier Jay Weatherill has announced plans to construct the world’s biggest single-tower solar thermal plant outside the city of Port Augusta — the 150 megawatt  Aurora Solar Energy Project . The AUD $650 million (US $512 million) plant will start construction in 2018 and be fully operational in 2020 — supplying 100 percent of the government’s energy needs. The project will deliver more than 700 jobs with local worker requirements.

The company’s $1 billion Crescent Dunes facility in Nevada was shut down for eight months due to structural fault. The Nevada facility was the first to use molten salt technology to store energy as heat — allowing for day and night operation. The South Australia facility will also use molten salt technology. “This will make a difference in the South Australia energy market,” said South Australian senator Nick Xenophon. “It will secure the grid and mean more baseload power than intermittent power.” + Aurora Solar Energy Project Via New Atlas Image via SolarReserve
