Comments Off on Chinese researchers develop flexible salt-powered batteries

As the world rushes to transition to a new energy economy, researchers are uncovering novel methods to harvest energy from mundane, everyday sources. A research team in China has created a new battery that could be safely used in wearable or implantable devices, thanks to its use of salt-based electrolytes. This breakthrough could drastically improve the quality and safety of battery-dependent medical technology and may even pave the way for sweat-powered devices. In order to be effective, implantable or wearable batteries need to be flexible to allow functional bending on organic surfaces. In prior iterations, these batteries usually included a mix of toxic chemicals that serve as the electrolytes through which electrical charge can flow. This new battery uses non-harmful electrolytes such as sodium sulfate and saline. Because there is less of a concern regarding leakage of these chemicals, the battery’s design does not require extra material to protect humans from exposure and is significantly less bulky.

The researchers also noted that the batteries have a marked ability to convert dissolved oxygen into hydroxide ions, which could prove useful in medical applications.  “We can implant these fiber-shaped electrodes into the human body to consume essential oxygen, especially for areas that are difficult for injectable drugs to reach,” said researcher Yonggang Wang. “Deoxygenation might even wipe out cancerous cells or pathogenic bacteria since they are very sensitive to changes in living environment pH. Of course, this is hypothetical right now, but we hope to investigate further with biologists and medical scientists.” Via Engadget Images via Deposit Photos , Tim Simpson/Flickr  and Andy Armstrong/Flickr

Comments Off on Solar-powered Tesla Tiny House hits the road in Australia

Tesla’s taking to the streets to demonstrate their clean technology . A Model X is pulling around a tiny house showcasing a solar power system and Powerwall , giving the curious a way to check out their renewable technology in action. Electrek shared some stunning images of Tesla’s Tiny House , which is serving as a mobile design studio in major Australian cities. The Tesla Tiny House is incredibly eye-catching: clad in sustainable, locally-sourced chemical-free timber , the rolling design studio gives locals an up-close look at Tesla’s renewable wares. The Tiny House measuring 20x7x13 feet is outfitted with a 2 kW photovoltaic system with six panels. There’s also a Tesla Powerwall on the home’s exterior.

A tour with staff provides detailed information; Electrek quoted the company as saying: “The tour is designed to provide a one-on-one educational experience on how to integrate Powerwall and solar to seamlessly power an entire home 24/7, allowing Australian consumers to gain control and understanding of their power use.” According to Electrek, Australia is a key market for Tesla’s products: 1.5 million households in the country have solar for the highest per capita penetration of rooftop solar power in the world. Tesla plans to take their tiny house to Adelaide, Melbourne, Sydney, and Brisbane throughout August, September, and early October. But, the company says on their site that anyone in Australia can request a stop. They “want to bring the Tesla Tiny House to you, so you can fully experience what it means to be self-powered.” + Tesla Tiny House Via Electrek Images via Electrek/Tesla
