ICYMI: Pig poop could make more eco-friendly roadways
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: The chemical makeup of pig manure is so similar to petroleum that it's being tested as a more bio-friendly way to make asphalt roads, while the leftover bits can be used as fertilizer. Since pigs already produce 43 billion gallons of manure each year, re-using some for road construction might be the smartest thing we've done with bioengineering yet.

New 'semi-solid' battery could recharge EVs as fast as pumping gas
Researchers at MIT reckon they've struck oil. In fact, you're looking at what they call "Cambridge crude" -- a substance that could halve the weight and cost of EV batteries and make them quicker to charge too. The black goo is packed with a high concentration of energy in the form of particles suspended in a liquid electrolyte. When separated by a filter, these particles function as mobile electrodes that can be pumped into and around a system before the energy is released. So instead of waiting up to 20 hours to juice your Nissan Leaf, you could potentially just pump this pre-charged substance into it -- rather like dirty old gas. Until now, no such "semi-solid flow cell" has been able to hold useful quantities of energy, but this stuff literally oozes with it. Not only could it power EVs, it could even be used for large-scale electricity storage for utilities. The researchers insist this energy revolution is years off -- but when it comes, there will be blood.
Scientists convert glucose into fuel and polyesters
Glucose has been the building block for many zany creations 'round these parts, but using the widely available substance to create "products currently created from petroleum" has some fairly far reaching consequences. Gurus at the Pacific Northwest National Laboratory have reportedly "converted sugars ubiquitous in nature into a primary building block for fuel and polyesters," dubbed hydroxymethylfurfural (HMF). Aside from the obvious benefits of finding yet another renewable energy to tap into, learning to harness this power could give garb and plastic manufacturers new routes to source raw materials. So what do the creators themselves think? "The opportunities are endless" -- we say: prove it.
