The first phase of a working unit that can remove greenhouse gases from ordinary air is to be completed by the end of this year, according to a report in Chemistry & Industry magazine. Marina Murphy describes the groundbreaking work being done by brothers Allen and Burton Wright (and Burton’s engineering firm, Kelly Wright & Assoc, Tucson, AZ) to create a wind scrubber – a 10 square metre structure that will capture excess carbon dioxide (CO2) from the atmosphere around it.
Scientists have so far only discussed the theory of ‘wind scrubbing’ - this will be the first attempt to build a practical model. Unlike stack scrubbers, which address highly concentrated carbon dioxide streams, the Wrights will be looking at ways to process large volumes of air at low CO2 concentrations. Allen Wright describes the project as “feasible, and with some development, economically practical,” says Allen Wright. The design will be finished by the end of summer 2004, and the first phase of the prototype will be up and running by the end of the year.
Although some scientists agree that the project is a big step forward, others are less enthusiastic.

Waste in the water – New purification techniques for healthier aquatic ecosystems

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
