We included Amprius, which was launched in 2008 as a spin out from Stanford University, on our list of 13 battery startups to watch in 2013. The startup has developed a battery based on research from Stanford’s Yi Cui, and its lithium ion batteries, announced Tuesday, use a nano-structured silicon material for the anode part of the battery.

A battery is made up of an anode on one side and a cathode on the other, with an electrolyte in between. Amprius’ nanostructured material allows the anode to be shrunk fourfold, delivering a fourfold increase in energy density.

Battery energy density is the amount of energy that can be stored in a battery per given volume. Amprius said its initial batteries can deliver 580 and 600 watt hours per liter, and its next-gen batteries can deliver 650 and 700 watt hours per liter. Traditional lithium ion batteries are operating at closer to 400 watt hours per liter.

Another one of the challenges that Amprius said it has overcome when building this battery is that it has had to engineer the silicon to make it stable enough to be charged and discharged repeatedly over time. The more stable the silicon, the longer the life time of the battery. Amprius said the anode can be charged and discharged more than 500 times while retaining 80 percent of the original capacity (a requirement for original equipment manufacturers, or OEMs).

Amprius is supplying its batteries to unnamed smartphone and tablet OEMs and is also working with OEMs to design its batteries in custom ways to fit into new consumer electronics, it said. The next-gen batteries are supposed to go into pilot production later this year.

Amprius has raised at least $25 million from investors including the ones listed above as well as IPV Capital, and Trident Capital. The company has an R&D lab in Sunnyvale, Calif., and an R&D lab and pilot production line in Nanjing, China.

Investor Steve Jurvetson next to a pulse fridge that cools a D-Wave quantum computer

As you can see in this photo from venture capitalist Steve Jurvetson, D-Wave uses a pulse fridge to cool the quantum computer to .02 degrees above absolute zero, and they use Helium-3 in the cooling process.

Quantum computers use a different type of processing compared to traditional computing. As GigaOM’s Jordan Novet explained it earlier this year, “rather than working with binary yes-or-no questions — ones and zeros — quantum computing is more probabilistic, also allowing a combination of zero and one to simultaneously answer many questions with quantum bits of information, or qubits, and tell users more about the likelihood of a situation. It’s not necessarily useful for all kinds of computing, but it could solve problems that current computers can’t.”

Keeping quantum computers that can perform such functions cool can be a tricky process. It’s highly energy intensive and can get expensive. But if the quantum computers are not cooled down, the molecules — which are being manipulated to store data — move around chaotically and can’t be manipulated and read.

Earlier this year physicists at UCLA developed a new cooling process that immerses charged barium chloride molecules into a super cold cloud of calcium atoms. That research is being funded by the Army Research Office and the National Science Foundation.

Between the two, they have more than 2,500 wireless charging installations at public locations such as airports, coffee shops, malls and arenas. PowerKiss recently added some charging mats at select McDonalds Europe locations. The idea behind these installs is to allow customers to place their mobile device on a wireless charging pad and add juice to the battery. Of course, the device has to natively support wireless charging, such as Nokia’s Lumia 920, or be compatible with an add-on product such as a wireless charging cover.

Overall, the ability to recharge a device by placing it on a special mat really hasn’t taken off with the mainstream public. Part of the reason is a battle over the technology standards: If you have a device that supports wireless charging but doesn’t work with a compatible charging mat, you’ll have to plug in your device, of course.

Powermat Technologies is part of the PMA, or Power Matters Alliance, which boasts that 80 percent of its partner members represent the entire wireless install base. That sounds good, so what’s the issue?

Well, there’s another body, the Wireless Power Consortium, that’s been at this longer than the PMA by about four years and uses the Qi-branded standard. Even worse: Some partners are members of both groups. So while the PMA gained a new member through marriage, there are still plenty of fish in the sea using a different wireless standard.

The company is looking to use the funding to help commercialize its batteries, which they’re calling Aurora, and Eos Energy hopes to deliver those to the market in 2014. According to a filing, this B round has been under development for over a year, and the company also says in its release that it is already in the process of raising a series C round, too.

Eos Energy is testing out its first batteries with New York utility ConEdison, and the two are using a state grant to install batteries on the New York grid. The company says it also has other utility partners in the works.

Scientists have been working on using air as the cathode for batteries for half a century. A battery is made up of an anode on one side and a cathode on the other, with an electrolyte in between. Air, of course, is abundant, light weight, and doesn’t require a heavy casing to contain it inside a battery cell. Also theoretically air can achieve a high energy density, or amount of energy that it can store.

Eos Energy tech innovation comes from founder and inventor Steven Amendola who discovered a breakthrough with his original design of the bi-directional air cathode that could last for 10,000 cycles (or around three decades). The company has told me that its initial battery could cost $160 per kWh, lasts 30 years and be made up of everyday benign materials.

• Green IT Q1: Cleantech Breaking Out — and Bracing for Hard Times

The Pacific Northwest National Laboratory has completed a study that comes up with two ways to use compressed air technology to store wind energy in underground chambers, the national lab said Monday. The two ways both use data and computer modelling to figure out the best sites that could successfully bank wind energy to be used at a later time.

Compressed air, as its name suggests, makes use of an electrically powered air compressor that sends pressurized air into a storage facility, which can be man-made or an underground reservoir. The pressurized air is let out later to run a turbine and generator to produce electricity. As much as 80 percent of the electricity used to compress air can be recovered when the pressurized air is used to generate energy, the lab said. Power losses are common when converting one form of energy to another.

Power in under ground caves

Utilities in the Northwest have a good reason for taking a look at energy storage technology. Wind power makes up about 13 percent (8.6 GW) of the power supply for the Northwest, the national lab said. Wind power tends to be most plentiful at night, when demand is at the lowest. Storing wind power for use during the day would help utilities meet their customers’ demand and manage their grids, which run smoothly when there is a balance of supply and demand. That prompted the Bonneville Power Administration to work with the lab to look into whether compressed air would be a good fit.

Many U.S. utilities or power producers have done preliminary studies or even pilot projects to check out different types of energy storage technologies, including various types of batteries. Often their regulators require them to gradually increase the amount of renewable energy they supply to their customers. Wind and solar have been popular choices, but they don’t generate a steady supply of electricity around the clock. Here is where energy storage comes in handy to help utilities manage their supply and demand.

The researchers were looking for two suitable underground sites for storing compressed air. They used data from gas exploration in Washington state and a computer model that simulates the flow of fluids underground. The idea is to see how much air a site can hold and how easy it’d be for the air to be harvested for power generation. For the study, an ideal underground storage would be at least 1,500 feet deep and 30 feet thick, and it should be close to transmission lines, the lab said.

Pacific Northwest

They found two locations, a place by the Columbia River, just across from Boardman, Ore., and another one in the Yakima Canyon that is roughly 10 miles north of Selah, Wash.

The scientists then sketched out two different processes for storing and re-using energy. At the Columbia River location, which is close to a natural gas pipeline, a compressed air storage plant can use natural gas to heat the compressed air and in the process boost the amount of electricity that can be produced.

At the Yakima location, the facility can use geothermal heat to run a chiller, which will in turn cool the air compressor to make it run more efficiently. Geothermal energy also can heat up the compressed air when it’s released from storage.

Bonneville will now take the results of the $790,000 study and do a round of cost-and-benefit analysis to figure out if compressed air makes for a good business case.

Nikola Tesla. Photo courtesy of Wikipedia

Last night I tweeted a link to this video, about the legendary scientist Nikola Tesla pitching Silicon Valley venture capitalists, and commented that the truth is sometimes funnier that comedy. And I was surprised by the sheer number of people who agreed with that sentiment. I went to sleep thinking about that reaction, and also thinking about it in the context of the decline of long-term thinking in our society.

If Tesla (I assume you know who he is) did indeed walk into a VC meeting, he wouldn’t get the attention or the money for his idea because it wouldn’t fit the time-scale of what venture-capital investments have become. Having followed the business of technology for a long time, I have seen that time-scale get shorter and shorter. I guess it’s the price to be paid for the excesses of the internet bubble of the 1990s.

The Bubble After Effects

During that time the business changed from funding innovation to funding concepts and eventually to projects. The fallout of the internet bubble was that venture-capital firms shifted focus. This shifting time-frame is one of the main reasons we are seeing fewer and fewer investments in hardcore technologies and more of the dollars being shifted to the softer aspects of technology.

Yes, bloggers like me like to harp on the fact that many investors are infected by short-termism. But let’s not forget that some of these folks have taken big risks, and sometimes have failed big, too.

Cleantech has ruined many reputations and resulted in billion dollar loses. Yes, there are a couple rare big bet successes that will come out of cleantech, like Tesla Motors and Nest, but the overall trend has been losses.

Now many of the investors that aggressively backed cleantech are trying to find a more cautious approach to cleantech that more closely aligns with the traditional short VC time frame. Kleiner Perkins Caufield & Beyers, which lead the charge on cleantech investments only to be left wounded, has recently changed tact in many ways, and in particular to go after social so it can get back into the quick returns on its investments.

That’s the trend that all investors, in some respects are, moving toward. They’re all looking for the next Facebook or the next Twitter, but no one wants to look for the next Juniper or the next Intel or even the next ARM. I am not saying Facebook and Twitter are not great companies and have not scaled dramatically and impacted the world. What I am pointing to is the fact that Silicon Valley funds fewer and fewer silicon companies.

Why are we assuming that we are all done with developing new kinds of chips for uses that we are not even imagining yet? Are we done inventing the routing technologies of the future?

It’s hard to invest in the future

Think of it this way: Had Vinod Khosla not backed Pradeep Sindhu to work on Juniper, we would all be living in Cisco’s vision of the internet future and using its hardware, which it would have made and sold at its own pace and at its own prices. Today, if you need to build a big company like that, you need to have deep pockets. Luckily Andy Bechtolsteim has those and that is why Arista Networks exists and is proving to be a major disrupter.

The point is not to just rant, but to note that there is a lot more innovation to be done. All of today’s stars — from Dropbox to SnapChat to every little hot company that pops up — is built on those basic building blocks, and we have to continue to make better, cheaper and beefier building blocks.

Yes, I understand that there is a chill around chip stocks, and Wall Street investors are showing more interest in pokes than petabyte speeds. I don’t necessarily think that this kind of rational thinking is bad for the investors, but when it comes to fundamental innovation, it points to a a real challenge ahead. And forget what Wall Street thinks, isn’t venture capital really risk capital? Risk, unfortunately, is a four-letter word around these parts these days.

Failure is an option

Elon Musk in front of the frunk

Forget chip startups, does anyone think that the Sand Hill Road firmament could have funded Amazon Web Services, a disruptive economic force, if they had a chance? Probably not. How about the iPhone? The same story. If you look at those two examples, and add Google’s self-driving car, Google Glass and what companies like Tesla are doing, you understand that patience is a virtue. Unfortunately, patience is in short supply in the Valley these days.

I wrote this on the first anniversary of Steve Jobs’ death, and I want to resurface it:

A dear friend put it best when he said that Jobs allowed himself the freedom to dream big and most of us need to learn from him and supersize our dreams. While that is true of everyone, the Silicon Valley of 2012 needs to pay heed. Silicon Valley of quick flips, petty jealousies and rampant short-termism needs to remind itself of a greater purpose than a public offering. Change is more than a headline. It takes patience. It is more profound. And it is thinking about more than just us.

Maybe this video is a reminder to all of us that while we might be living in great times, the future is still to be invented.

More about the video: The video is in support of a Kickstarter campaign that hopes to collect enough money to build a statue of Nikola Tesla. While to many Tesla might be a car, in reality Tesla was a scientist who worked on difficult things. As an aside, we at GigaOM are fortunate that our New York offices are in the Radio Wave Building, the very building where Nikola Tesla lived.

• 12 tech leaders’ resolutions for 2012
• The fourth quarter of 2012 in cleantech
• Facebook’s IPO filing: ideas and implications

Think of water rushing in through the open hatch of a submarine, and you get an idea of the forces at work underwater. Atmospheric pressure and the weight of the water combine to create pressures that compound with increasing depth. At a depth of 400 meters (almost a quarter mile), for example, the pressure is that of 40 atmospheres, one atmosphere being the pressure we experience at sea level. Subhydro envisions installing large concrete tanks at depths of 400-800 meters, and the deeper the better for maximizing energy generation.

When the “hatch” is opened, water is allowed to flow into the tanks through a turbine that drives an electric generator. The more and larger the tanks, the longer the generation can go on. When the tanks are filled, the turbine can be reversed to pump out the water, a process that draws on the power grid and consumes energy. In this way, the pumped storage plant functions like an underwater battery that can be re-charged, much like a hydroelectric plant on dry land pumps water into an upper reservoir after it has passed through a turbine.

According to Subhydro, the efficiency of the underwater plant is about 80 percent, comparable to efficiencies achieved at conventional plants. Integrating the pumped storage plant with wind or solar farms could create a grid storage system that harnesses excess renewable energy generation to pump out the tanks and flood them during peak hours of production.

Another approach to underwater grid storage is in the works at a depth of 80 meters in Lake Ontario, just off shore of Toronto. There, Hydrostor will begin building underwater tanks that will hold compressed air. Surplus energy from renewables (wind, solar) will provide the energy to compress air from the atmosphere and pump it in to the tanks. To put energy back into the grid, the air is allowed to surface, driving generators as it expands back into the atmosphere.

Hydrostor is partnering with Toronto Hydro to build the 1MW/4MWh compressed air energy storage demonstration facility. The system will run at 70 percent efficiency, according to Hydrostor. Earlier this month MaRS Cleantech Fund announced an investment in Hydrostor’s tech.

Clearly, there are still some hurdles to overcome before energy companies everywhere take the plunge. The environmental impact of offshore submerged facilities will need to be considered, as will the building materials themselves. To withstand the underwater pressure, Subhydro is working with research partners to develop thin concrete reinforced with steel fibers, while Hydrostor’s system will use inflatable polyester bags to hold compressed air. Building underwater facilities is itself energy-intensive, so whether the process can be made cost and energy-effective will determine whether cleantech is ready to get its feet wet.

For example, rural Kenyan farmers can easily spend 30 percent of their income on fertilizer, but 80 percent of that fertilizer can be wasted because there is little data collected about the best places and times to use it. The lack of info isn’t just from the farmer’s perspective. Aramburu says when he met the CEO of a major fertilizer company recently, he asked him what he knew about his customers — his response: “very little.”

Re:char CTO Luke Iseman (L) and founder/CEO Jason Aramburu (R) showing off an early prototype of SoilIQ

A soil data cloud in the sky

The two young entrepreneurs latest project emerged from this black hole of information. Working within French telco giant Orange’s first accelerator program, called Orange Fab, Re:char plans to build a $5 plug-in device, called SoilIQ, for an Android phone that can read the moisture levels in soil. During our interview, Iseman takes a very early prototype of the device out of a pouch and shows me how it plugs into the Android phone and taps into the phone’s computing power to detect moisture levels between two screws.

Down the road such a gadget could be developed to pick up other soil data, like fertilizer-level readings. Iseman, an avid gardener, schools me on NPK — nitrogen, phosphorus, and potassium — which he says are the holy grail of fertilizer readings. When SoilIQ is a commercial product, farmers could buy the gadget to take these types of readings, and enhance their farming productivity and the efficiency of their fertilizer use.

But the real value of such a system will likely be in the data collection, and the data analytics and services. The hourly and daily micro readings, which are coded with GPS data, could be used to create a cloud-based location data map of the quality and details of the land. This information could be used to launch data-focused services for both farmers, fertilizers companies, government groups, and others.

Re:char envisions using the data to launch a subscription service for farmers that can alert the farmers to the most fertile land, or even if there’s the danger of crop disease anywhere in the region (maize rot is a huge problem in rural Kenya). Fertilizer companies could use such data to offer better products to farmers, and potentially learn more about the end farmer customer (fertilizer can change hands ten times in Kenya until it reaches the person who will use it, says Aramburu).

Such land data could even be valuable outside of the farming communities. A massive data soil map in the cloud could help determine things like land values, or land ownership issues.

SoilIQ is part internet of things, part sustainability, and part data analytics. The entrepreneurs are actually very focused on developing tools that encourage the more efficient use of resources, which could (and should in my opinion) be the next-generation of cleantech focus.

The core concept also reminds me of what Safecast has been trying to do with its grass roots nuclear radiation sensors and data mapping in Japan. Safecast is bringing that concept to air pollution in L.A., too.

Orange interest

For telco Orange, which has a substantial presence in Kenya, such a system could help them increase mobile data use among customers. The Android devices obviously send the data to the cloud over the cellular networks. And Android phones — as Google announced this week at Google.io — are being used by 900 million people globally.

But potentially even more important is the branding involved. As Orange’s Executive Director of Business Services, Vivek Badrinath, told me in an interview at the Orange Fab event on Monday night, the mobile phone is often times the first branded product that a customer in a developing country has. That brand in turn has a unique ability to transition into offering core services, like mobile banking, and credit.

Orange has a mobile payment system, Orange Money, that is growing nicely and Re:char could plug into it for its planned services. And if SoilIQ becomes a killer app for the bottom of the pyramid, Orange would have a key position in it. Orange is interested enough in Re:char’s new idea that it not only brought the company into its accelerator program, but is investing in its angel round.

Re:char hopes to close an angel round by the end of the program, and later this year raise a series A round. By the end of the three months, Re:char also plans to have its soil moisture-reading gadget developed enough to move it into production.

If you’re a backyard composter or gardener — like Re:charge CTO Iseman — you’re probably wondering if you can get your hands on SoilIQ one day. Aramburu and Iseman tell me that they’d like to make it available in the U.S., too, so the gardening hobbyist could collect their own data.

Clearly, the team is in the very early stages of making SoilIQ, so a lot of their plans will hinge on these next few months. They plan to keep running the kiln bio charcoal business, and think SoilIQ could even help grow that business, too. They also might split the businesses in two down the road.

Ultimately if they can deliver a simple, easy to use, and cheap device, and convince Kenyan farmers to start using it, they could be on their way to unleashing data from Kenya’s rural landscape.

One of the underwater Streetview cameras, on display at Google I/O.

Google launched Streetview for the world’s oceans in cooperation with Underwater Earth the at the end of last year, and has mapped a total of six sites so far, including the Great Barrier Reef in Australia as well as reefs in Hawaii and the Philippines. Vevers explained that his organization’s Catlin Seaview Survey has been using divers carrying custom-made cameras that shoot photos every three seconds, with divers being able to cover about two kilometers during every expedition.

That’s slow — maybe too slow. The world’s coral reefs are receding quickly, which has been one of the main motivations behind the project. “We set up our project to reveal the reefs of the world,” Vevers said, adding: “People don’t want to protect anything they can’t see.”

However, Verers said showing off the beauty of coral reefs to the world is only “half the story.” The project has also been working on image recognition technologies, with the goal of mapping species and giving scientists around the world access to new material to work with.

So why did Google get involved with the project? Foulkes said that it wasn’t driven by commercial motivations, but freely admitted that it was also about showing off the capabilities of Google Maps. One example: Vevers’ team uses Google’s business photos tool, which is meant to give stores the ability to upload panoramic photos, to create its underwater photospheres.

Vevers’ plan is to capture and reveal all of the world’s coral reefs within the next three years. “We feel this is very much a race against time,” he said. That’s why the project now wants to enlist amateurs in its quest as well. Divers can simply use their cell phones in water-proof cases and then upload their photospheres to Google Maps. And he urged volunteers to become active soon: “What happens in the next ten years is likely going to affect our oceans fo the next 10,000 years.”

The artificial leaf’s titanium dioxide and silicon nanowires are arranged in an array that actually resembles a microscopic forest of straight pines. The key to achieving good solar-to-fuel conversion efficiency is the integration of the components — the nanowire semiconductors that absorb light, an interfacial layer, and co-catalysts for the water splitting reaction — in a structure that resembles and functions like a chloroplast.

Plants are so efficient at turning sunlight into sugars partly because of what is termed the “Z-scheme”: the daisy chain of molecules that deliver a charged electron from a chloroplast to molecular energy production in the cell. The artificial leaf uses the Z-scheme, too, but with the silicon nanowires responsible for the hydrogen generation and the titanium dioxide nanowires contributing to the formation of by-product oxygen. The use of two semiconductor materials allows for a large part of the sunlight spectrum to be harnessed (the silicon works off visible light and the titanium dioxide uses UV), while the forest-like array of nanowires increases the surface area for the solar-to-fuel reactions, which are helped along by embedded catalysts.

The artificial leaf has a conversion efficiency of 0.12 percent, comparable to that of natural photosynthesis. To be commercially viable, the efficiency number will have to get into the single digit percentages, and companies like MIT spin-off Sun Catalytix have already chosen to refocus their efforts away from artificial leaf tech. Replacing the current-limiting titanium dioxide anode in the system is the Berkeley researchers’ next target for improving conversion efficiency.
