Governments have a key role to play in reducing uncertainty by sending strong and consistent signals about their climate ambitions and implementing specific policies to fulfil these long-term goals.
The Solar Metal Smelter features a large lens that is manually moved to follow the path of the sun and direct its heat into a crucible holding metal. Once liquid enough, the metal can be cast into a sand mould and made into a variety of products.

For the first time, steel will be industrially recycled from the heat of the sun alone. The solar furnace could melt up to 400 tons of recycled steel each year. The ingots will be reused by Panatère or sold to other companies.
O processo de modo a gerar energia fotovoltaica acontece em larga escala nas usinas solares ou para uso mais restrito em sistemas particulares On Grid e Off Grid, de que podem vir a ser instalados usando kits solares.
The growing market for wind turbines with permanent magnets – particularly for offshore projects – could dramatically increase demand for rare earths over the coming decades
In the High gallium arsenide case, demand for arsenic, gallium and indium in 2040 are around twice as high compared to the base case in the SDS.

It takes a small turn of a hand crank every five to ten minutes to move the lens along a track to its ideal position.
Alkaline electrolysers are currently the most widely used. They have low capital costs, partly because of their avoidance of precious metals, but current designs do require nickel in quantities of more than one tonne per MW. Reductions in nickel demand for alkaline electrolysers are expected, but nickel is not expected to be eliminated from future designs. However, even if alkaline electrolysers dominate the market, then nickel demand for electrolysers would remain much lower than that for batteries in the SDS. Proton exchange membrane (PEM) electrolsyers are more expensive today, but are already being deployed in large facilities as they are smaller and more flexible.
