Researchers turned wood into a better insulator than Styrofoam
The research lab behind the creation of see-through wood has developed a new type of material that could be used as a cheaper, stronger and more environmentally friendly insulator. They're calling it nanowood and it insulates better than Styrofoam and silica aerogels. "This can insulate better than most other current thermal insulators, including Styrofoam," Tian Li, a researcher on the project, said in a statement. "It is extremely promising to be used as energy efficient building materials."
Mealworms convert Styrofoam waste into usable soil
Researchers have found a scourge for the 33 million tons of plastic dumped each year in the US: mealworms. A team from Stanford and China's Beihang University found that the beetle larvae stay perfectly healthy eating just Styrofoam, which is normally considered non-biodegradable. Better still, the worms convert the plastic to CO2 and waste that's safe to use as soil for crops. The scientists were as surprised by the discovery as you might be. "There's a possibility of really important research coming out of bizarre places," said Stanford professor Craig Criddle. "This is a shock."
Styrofoam touches electrodes to create incredibly fast-charging wonderbatteries
Elon Musk's heart may have already given up on the humble battery, lusting after capacitors, but researchers at the University of Illinois have think there's life in the 'ol cells yet, creating batteries that charge and discharge in seconds. They've found a way to create electrodes using polystyrene beads as a sort of substrate, tiny spheres helping to set the porosity of either the nickel-metal hydride or lithium-manganese capacitor material. By adjusting the size and density of the bean bag innards the team was able to create an electrode porosity of 94 percent, which is just a few ticks short of theoretically ideal for exposing the maximum surface area of the electrode to the battery material. This results in extremely fast charges and discharges, the NiMH cell hitting 90 percent capacity in just 20 seconds and discharging in as quickly as 2.7 seconds. While we don't know just what kind of charging system the team was using to achieve this, even assuming a high-amperage stream of electrons this is still a remarkable feat. But, like most major advances there's a drawback: similar to Toshiba's SCiB batts the capacity of these cells is only about three quarters what it would be using normal battery construction, meaning you'd need roughly 25 percent more mass to get the same range in your ultra-fast charging EV of the future. That might just be a worthy trade-off.
22-foot tall robot crafted entirely from excess styrofoam
Building a big robot is nothing to congratulate yourself on, but doing it in this manner is certainly worthy of a little self-indulgence. The creature you see standing before you is a 22-foot tall Styrobot constructed entirely from spare polystyrene packing materials, and no, each piece didn't just show up that way. Michael Salter managed to whittle away on this beast until its completion, and now we're hearing that it'll be going on a short demonstration tour before being "decommissioned." We say throw a brain in there and see what happens when you cut it loose.[Via TechDigest]
