A future without power lines? Fuel cell electrodes built with stainless steel are stronger, easier to manufacture, and cheaper than ceramic electrodes. This new kind of solid oxide fuel cell could generate electricity as cheaply as the most efficient gas turbine. On-site, pollution-free electricity from fuel cells could serve neighborhoods and industry without the need for long-distance power lines. Slow wetting
in a hot bath The standard equation for how a drop of liquid wets a solid surface doesn't work when the liquid is molten metal and the surface is hot. Why not? It's been a mystery for 200 years. Now Berkeley Lab researchers have been awarded $50,000 for discovering the answer. A hint: ridges riffle running metal. Crops suffer as climate changes |
