Saving energy is a beautiful thing—a phrase taken quite literally by the creators behind the world's first “learning thermostat,” the Nest. Its sleek and sexy interface is enough to win over the hearts of the iPhone generation, but its technological genius is starting to win over the power market. Last month, Nest Labs revealed the new and improved Nest v3.5, while at the same time making its energy-saving features available across the nation with the help of a few strategic partnerships in the US utility market.

While most of us hardly notice thermostats, the tiny boxes adorning the walls of every home in America control a whopping ten percent of the country's energy consumption. Tony Fadell—one of the great minds behind many generations of the iPod and iPhone—didn't think they mattered either until he realized they also account for half of homeowners' energy bills. Inspired and disappointed by the lack of options available on the market, he decided to redesign the inefficient and boring looking “beige box from the 90s,” and create something that makes more sense for consumers in the 21st century.

Although Nests have been abuzz throughout Silicon Valley circles since the product first came to market in late 2011, it wasn't until now that a few strategic partnerships with power companies enabled its true accessibility across the country. NRG Energy subsidiaries like Reliant, Green Mountain Energy, Austin Energy and Southern California Edison will deploy Nest's next-generation thermostats around the US this year, offering instant online rebates to Nest customers. With minimal effort, the Nest will help most users save around 20 percent on energy bills each year, teaching them how to do even better over time.

Rush Hour Rewards, Seasonal Savings

Coinciding with moves to put Nests in thousands of new homes, Fadell and fellow former top Apple employee Matt Rogers have taken Nest functionality to the next level with tech-driven features to help reduce energy demand during peak periods, without customers losing control of their own comfort. Today, energy companies spend billions of dollars in unsuccessful efforts to incentivize people to reduce power demand during peak times like hot, summer days.

Nest's Seasonal Savings and Rush Hour Rewards features make use of the built-in Auto-Tune program, designed to automatically reduce power at key moments, while employing pre-cooling or personalized air conditioning cycling techniques to keep homes at comfortable temperatures. The system essentially learns about peoples' homes and behaviors to provide feedback and options that require minimal effort.

“By expanding our relationship with NRG, we can continue working together to turn the conversation away from cost alone toward a broader discussion about energy choices,” Fadell said in a statement. “Bundling the Nest Learning Thermostat with energy plans was a great first step. Now, the integration of Nest’s new Rush Hour Rewards and Seasonal Savings services promises to spark even more conversations about energy among NRG’s customers.”

That takes a huge load of the shoulders of local utilities, often forced to power up other plants or buy more power from third parties at higher rates as everyone cranks up the AC during summer.

"We understand when peak demand is coming," Fadell told CNET, "and work with your Nest, moving the energy load around so we don't have a peak energy problem."

Nest v3.5

Following last summer's record breaking hot months, the next-generation Nest (v3.5) is revealed at an ideal time, with a number of smarter features, including:

  • Sunblock: the ability to track sun patterns within a house, automatically adjusting to correct temperatures under direct sunlight. Connected to WiFi, the Nest will also take into account sunrise and sunset to avoid cooling too much in the summer or heating too little in the winter.

  • Advanced Fan Control: modes that allow users to control when and how long fans throughout the house should run for any given day.

  • Cool to Dry: AC that kicks in when humidity reaches excessive levels and becomes damaging to a home.

  • Improved Auto-Away to predict how long the house is vacant to help users save even more energy.

  • Apps, available on mobile and tablet devices, with improved messages/alerts and easy remote access to the Nest

"These services are new--radically new--and dramatically different than any previous efforts by energy providers and thermostat makers to get their customers to save energy," Fadell said in a post.

The new approach to a very traditional and vital industry is just the beginning of a larger conversation sweeping the nation. For now at least, here's to a better summer.

For a more in-depth discussion, watch this interview with Tony Fadell at LeWeb Paris 2012:

UPDATED: In another announcement this month, Nest Labs, Inc acquired MyEnergy, a service that allows people to track their electric, gas and water usage in one place online, with users in all 50 US states, cover over 1,500 utility territories. 

“With less than 25 percent of the U.S. population connected to the smart grid, we’ve focused on developing technology that makes it easy for people to access the information they need to make decisions about their energy use,” said Ben Bixby, co-founder and CEO of MyEnergy. “We’re excited about the opportunity to join Nest to continue giving people useful, actionable information.”

Itronics successfully tests manganese recovery process

Itronics - a Nevada-based emerging cleantech materials growth company that manufacturers fertilisers and produces silver - has successfully tested two proprietary processes that recover manganese, with one process recovering manganese, potassium and zinc from paste produced by processing non-rechargeable alkaline batteries. The second recovers manganese via the company’s Rock Kleen Technology.

Manganese, one of the four most important industrial metals and widely used by the steel industry, has been designated by the US Federal Government as a "critical mineral." It is a major component of non-rechargeable alkaline batteries, one of the largest battery categories sold globally.

The use of manganese in EV batteries is increasing as EV battery technology is shifting to use of more nickel and manganese in battery formulations. But according to the US Department of Interior, there is no mine production of manganese in the United States. As such, Itronics is using its Rock Kleen Technology to test metal recoverability from mine tailings obtained from a former silver mine in western Nevada that has a high manganese content. 

In a statement, Itronics says that its Rock Kleen process recovers silver, manganese, zinc, copper, lead and nickel. The company says that it has calculated – based on laboratory test results – that if a Rock Kleen tailings process is put into commercial production, the former mine site would become the only primary manganese producer in the United States.

Itronics adds that it has also tested non-rechargeable alkaline battery paste recovered by a large domestic battery recycling company to determine if it could use one of its hydrometallurgical processes to solubilize the manganese, potassium, and zinc contained in the paste. This testing was successful, and Itronics was able to produce material useable in two of its fertilisers, it says.

"We believe that the chemistry of the two recovery processes would lend itself to electrochemical recovery of the manganese, zinc, and other metals. At this time electrochemical recovery has been tested for zinc and copper,” says Dr John Whitney, Itronics president. 

“Itronics has been reviewing procedures for electrochemical recovery of manganese and plans to move this technology forward when it is appropriate to do so and has acquired electro-winning equipment needed to do that.

"Because of the two described proprietary technologies, Itronics is positioned to become a domestic manganese producer on a large scale to satisfy domestic demand. The actual manganese products have not yet been defined, except for use in the Company's GOLD'n GRO Multi-Nutrient Fertilisers. However, the Company believes that it will be able to produce chemical manganese products as well as electrochemical products," he adds.

Itronics’ research and development plant is located in Reno, about 40 miles west of the Tesla giga-factory. Its planned cleantech materials campus, which will be located approximately 40 miles south of the Tesla factory, would be the location where the manganese products would be produced.

Panasonic is operating one of the world's largest EV battery factories at the Tesla location. However, Tesla and other companies have announced that EV battery technology is shifting to use of nickel-manganese batteries. Itronics is positioned and located to become a Nevada-0based supplier of manganese products for battery manufacturing as its manganese recovery technologies are advanced, the company states.

A long-term objective for Itronics is to become a leading producer of high purity metals, including the U.S. critical metals manganese and tin, using the Company's breakthrough hydrometallurgy, pyrometallurgy, and electrochemical technologies. ‘Additionally, Itronics is strategically positioned with its portfolio of "Zero Waste Energy Saving Technologies" to help solve the recently declared emergency need for domestic production of Critical Minerals from materials located at mine sites,’ the statement continues.

The Company's growth forecast centers upon its 10-year business plan designed to integrate its Zero Waste Energy Saving Technologies and to grow annual sales from $2 million in 2019, to $113 million in 2025.
