A salty battery bath to combat EV range anxiety

The degradation of electrodes in lithium-based batteries has been a major inhibitor to their operating life, particularly when dendrites "growing" from these corroding electrodes short-circuit in the electrolyte. Australian researchers have found that pre-treating lithium electrodes in a special salt bath decreases the breakdown of the electrodes and boosts performance and battery life so markedly it could bring an end to range anxiety for drivers of electric vehicles.Read More

New record energy efficiency for artificial photosynthesis

As the world moves towards developing new avenues of renewable energy, the efficiencies of producing fuels such as hydrogen must increase to the point that they rival or exceed those of conventional energy sources to make them a viable alternative. Now researchers at Monash University in Melbourne claim to have created a solar-powered device that produces hydrogen at a world-record 22 percent efficiency, which is a significant step towards making cheap, efficient hydrogen production a reality.Read More

Audi just created diesel fuel from air and water

Audi is looking to fuel the future without fossil fuels. One of the company's pilot plants in Germany has just produced the first batches of a synthetic diesel made using only water and air. The company's pilot plant, which is operated by German startup Sunfire, produced its first batches of the "e-diesel" this month. German Federal Minister of Education and Research Johanna Wanka put a few liters of the fuel in her work car, an Audi A8, to commemorate the accomplishment.Read More

New space race aims at creating breathable air on Mars

The race to reach Mars is more like a decades-long marathon, but in the short term the latest space race involves inventing ways that might make setting up shop on the Red Planet possible. In the past few months alone, three teams have unveiled their visions of how humans might breathe on the fourth planet from the sun. Read More

Record efficiency for converting solar energy to hydrogen without rare metals

Using solar energy to split water into its component parts, thereby allowing the solar energy to be stored as hydrogen fuel, generally involves one of two methods: using photoelectrochemical cells to directly split the water, or using solar cells to produce electricity to power an electrolyzer that separates the water molecules. One problem associated with the latter method is that it currently relies on rare metals. But now scientists from Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have managed to do so using common materials, and have achieved a record solar energy to hydrogen conversion efficiency in the process.Read More

SafeFlame torch turns water into fire

The pressurized acetylene and propane gas used in brazing and related tasks is highly flammable, and thus very dangerous. You know what isn't flammable, though? Water. Bearing that in mind, the European Union-funded SafeFlame consortium has developed a torch system that generates a flame using nothing but H2O and electricity. Read More

Immerse-A-Clean wand creates a cleanser from tap water

Janitors and other people who do large-scale cleaning certainly don't have an easy job. Among other things, they have to lug around heavy bottles of bleach or other cleansers, then risk the harmful effects of those products when using them. Texas-based GenEon Technologies, however, is now offering an alternative. The company's Immerse-A-Clean wand can reportedly turn regular tap water into an effective sanitizer, glass- and general-purpose cleaner, using nothing other than electricity and a non-toxic catalyst.Read More

New refining process could lower cost of titanium by 60%

Researchers at Case Western Reserve University (CWRU) have been selected by ARPA-E, the US government's Advanced Research Projects Agency - Energy, to carry out a one year project aimed at developing a low cost method to obtain titanium metal from its ore. It is thought that the process could lower the cost of the metal by up to 60 percent.Read More
