watch the nice video...

sounds a bit optimistic to me but interesting ...

can we use it for space :-) ?

for all those considering purchasing one of these SSDs

another rail-gun try

The new battery, which is described in the journal Nature, is based on an organic molecule-called a quinone-that's found in plants such as rhubarb and can be cheaply synthesized from crude oil.

Big Data bring new opportunities to modern society and challenges to data scientists. On the one hand, Big Data hold great promises for discovering subtle population patterns and heterogeneities that are not possible with small-scale data. On the other hand, the massive sample size and high dimensionality of Big Data introduce unique computational and statistical challenges, including scalability and storage bottleneck, noise accumulation, spurious correlation, incidental endogeneity and measurement errors. These challenges are distinguished and require new computational and statistical paradigm. This paper gives overviews on the salient features of Big Data and how these features impact on paradigm change on statistical and computational methods as well as computing architectures.

Stacking laser printed supercapacitors (no clean room required btw) has lead to about 1100F/g and thus about 20-40Wh/L. For supercapacitors thats pretty damn good. For reference, Li-ion recently reached 650Wh/L. The gap is closing, although for supercaps of this type the theoretical maximum is 1400F/g.

is this the breaktrough that we were waiting for?

That depends on what application you are thinking of. For circuit board electronics this will allow integration of micro sized supercapacitors to provide operational power. They will have to be fed by external batteries still, but the close proximity allows for better tailored power demands. They also propose tapping into thermal/mechanical energy to charge the supercaps. In the end, they can provide significant specific power (W/kg) but you still need to upscale the production to cover large areas to also gain high specific energy (Wh/kg). This breakthough is for micro sized applications, not for replacement of large scale energy storage (electric vehicles, satellites) going up to kWh. That said, I know of several studies in supercaps at ESA, but they are still qualifying current relatively old commercial solutions.

For the first time, researchers have shown that they can capture CO2 from the air, and convert it directly into methanol, which can then be used as an alternative fuel, as well as for hydrogen storage, in fuel cells, or as a building block for plastic.

Solar power to suck out co2 during the day and make it fuel finally solves global warming?

Imagine if your clothing could, on demand, release just enough heat to keep you warm and cozy, allowing you to dial back on your thermostat settings and stay comfortable in a cooler room. Or, picture a car windshield that stores the sun's energy and then releases it as a burst of heat to melt away a layer of ice.

interesting indeed: Such chemically-based storage materials, known as solar thermal fuels (STF), have been developed before, including in previous work by Grossman and his team. But those earlier efforts "had limited utility in solid-state applications" because they were designed to be used in liquid solutions and not capable of making durable solid-state films, Zhitomirsky says. The new approach is the first based on a solid-state material, in this case a polymer, and the first based on inexpensive materials and widespread manufacturing technology.

Maybe something to look at for Ricarda? Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a first-of-its-kind self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices. "There's no need for heat or light to fix the crack or break in a circuit or battery, which is often required by previously developed self-healing materials." Yu and his team created the self-healing gel by combining two gels: a self-assembling metal-ligand gel that provides self-healing properties and a polymer hydrogel that is a conductor.

Ricarda??
