Whoa, Graphene Can Make Other Metals 500 Times Stronger

Whoa, Graphene Can Make Other Metals 500 Times Stronger

We’ve heard about plenty of promising electronic applications for miracle material graphene from headphones, to super-fast transistors, to crazy camera sensors, and even solar-powered paint. But now scientists have found a way to leverage its raw strength, by using it to make metal up to 500 times stronger.

Empire Steampunk Speakers: For Dapper Audiophiles Only

There’s something that continues to intrigue me about Steampunk style. I think it’s the idea that technology could be driven by steam power instead of electricity. And while these speakers aren’t actually driven by steam, they’re still pretty amazing.

This pair of Empire Steam speakers was handmade by Airhammer Industries. Each octagonal cabinet is made from MDF with a copper veneer, copper edging, and brass and bronze details. They’re extremely substantial, as is evidenced by the large 1.5″ thick granite top on each one, and an approximate weight of 125 pounds per speaker.

Inside of each 36-inch-tall speaker is a pair of Vifa 1″ silk dome tweeters, a 5″ Pyle midrange, and a 15″ Goldwood downward-firing subwoofer for cranking out the bass while you watch The League of Extraordinary Gentlemen on your steam-powered television. Maximum power per speaker is 400 Watts RMS @ 8 ohms.

While these speakers are glorious, they’re not exactly cheap. All of this craftsmanship and audio tech will set you back a whopping $12,600 (USD) for the pair. I wonder how much they would have cost back in the 19th century?

The High Price of Copper


The High Price of Copper

Lithium may store the power that drives out modern mobile world but it’s copper that delivers it. This malleable metal is a vital component in modern homes, electronics, and agriculture. But our reliance on copper comes at a steep price, both economically and environmentally.

LG Chem develops very flexible cable batteries, may leave mobile devices tied up in knots

LG Chem develops cableshaped flexible batteries, may leave mobile devices tied up in knots

The world is no stranger to flexible batteries, but they’ve almost always had to be made in thin sheets — that doesn’t amount to a long running time if you’re powering anything more than a watch. LG Chem has developed a flexible lithium-ion battery that’s not just better-suited to our bigger gadgets but could out-do previous bendable energy packs. Researchers found that coating copper wires with nickel-tin and coiling them briefly around a rod results in a hollow anode that behaves like a very strong spring; mating that anode with a lithium-ion cell leads to a battery that works even when it’s twisted up in knots. Join multiple packs together, and devices could have lithium-ion batteries that fit many shapes without compromising on their maximum deliverable power. Some hurdles remain to creating a production-grade battery, such as a tendency for the pack to shed a small amount of capacity whenever it’s put under enough stress. LG Chem is fully set on turning these cable batteries into shippable technology, however, and could ultimately produce mobile devices and wearables that really do bend to their owners’ every whim.

IBM alliance sets efficiency record for solar power cells using common materials

IBM alliance sets efficiency record for solar power cells using common materials

There have been more than a few solar power efficiency records set in the past few months, let alone years. What makes IBM, DelSolar, Solar Frontier and Tokyo Ohka Kogyo think they can just waltz in and claim a record of their own? By using more commonplace elements in the periodic table, that’s how. The partnership’s new photovoltaic cell based on copper, zinc and tin (CZTS for short) can convert light rays to electric power with a 11.1 percent efficiency rate — still nothing to upset traditional silicon power, but a large 10 percent more efficient than anything else in the class. In its early form, CZTS can already be manufactured through ink printing and could be produced in quantities equivalent to about 500 gigawatts of power per year, or five times more than some of the next-closest alternatives. The group wants to improve CZTS’ efficiency over the course of the next several years, ideally reaching the point where it’s useful as a truly cheap, ubiquitous source of power. We’re looking forward to the day when there’s a little slice of solar energy in just about everything, hopefully including a few more hybrid cars and private aircraft.

Liberty DNA: The Watch Made out of Bits from the Statue of Liberty

There are watches and there are timepieces, and this has to be one of the most unique watches that I’ve every seen. This Romain Jerome watch isn’t the first watch that uses something famous in its makeup, their Iceland Volcano watch among others, but it’s definitely an interesting way to showcase your national pride.

Romain Jerome has used many exotic materials in its expensive watches. They’ve used volcanic ash, metal from the Titanic, and ever dinosaur bones. The Liberty-DNA watch uses particles from the actual Statue of Liberty, making it extremely limited. The watch also uses design elements to commemorate Lady Liberty, such as the face that’s reminiscent of her 12-pointed crown.

In celebration of the 125th anniversary of the Statue of Liberty, ther are only 125 of these watches being made, and if you have to ask the price, you probably can’t afford it.
