Elon musk has unveiled the battery that homes, businesses and utilities can use to store electricity. Teslas vision for batteries expanding way beyond cars. The new offering is called the power wall, a slim rechargeable lithiumion battery with an interesting price tag. It is flat against the wall, it has all of the integrated Safety Systems with normal controls, the ac dc converter. It is designed to work very well the Solar Systems right outofthebox. You can actually go completely off grid, take your solar panels, charge the battery pack, and thats all you use. It gives you safety security, and he gives you a complete and affordable solution. If 3500. Emily musk has a bigger product, called the power pack, that he wants to sell to utilities and big companies. The announcement comes at a state like california and new york are turning to relieve a congested and aging grid. Im joined by david and jeff, from the Argonne National laboratory. Gentlemen, thank you for joining me. Just, there are home batteries out there on the market. They have yet to really take off. How is teslas offering different . Jeff the thing we are excited about the offer he is making is drawing attention to the problem. The problem is that electricity is in on demand product. We turn knobs up and down to increased demand based on the consumers. We need to be able to store that energy for later use. The beauty of this problem if we solve what is the first world problem, and it is a desire for all of us to drive teslas and for those of you who havent driven one, i assure you, you want to. Its a wonderful car. And get electricity from the sun and the wind thats a real first world problem. We are phones the last along time. By solving this problem, we address a problem in developing countries. Countries with the grid is either unstable or doesnt exist. If we can cobble inexpensive solar and batteries like teslas offering, we can actually change lives. Hundreds of millions of lives around the planet. Emily how is teslas battery different or better than other batteries on the market . Is it about the tesla brand . Can they make batteries cool like its cars . David its integral to the cars. The sense i got from talking to analysts is that fundamentally the technology is not that radically different from whats out there. You are musk has been trying to perfect his batteries, make them run more efficiently. Hes presenting a part that is well integrated. You could for one of these in your house connected to the solar panel on your roof and there you go. If less cobbling things together that you had to with the past. Emily how many households are using Battery Power were considering using Battery Power . Jeff its a very small fraction. When we think of the United States, its a small fraction, with the exception of hawaii and alaska. Hawaii is an island integrated, literally, and the cost is about . 35 for kilowatt hour. Solar is penetrate about 20 percent of the individual homes in terms of implementation and batteries are required for that application. I want to just echo what david said. The cost is between 350,000 350 per kilowatt hour. That is perfectly in line with most other battery offerings on the market. The question is one of integration. Emily the average Household Spending up to 3500 on a battery, is that really realistic . David it may be. The goal is to get that price to come down even more. Right now it will appeal to a pretty select part of the market, maybe people who live in a place where the grid is less reliable. Maybe its a place where there are more storms than others. Where you were a greater risk at getting kicked off the grid through brownouts and things like that. The goal is articulated by elon musk is to get the price of batteries down. First it was to push down the price of the cost of solar panels. Now, batteries have become the focus. I think its a hybrid and for everyone. Certainly, as we talk about how this might expand into the developing world, with a price tag like this seems prohibitive at this point. But as it catches on expands, that could change. Emily what does the Battery Market look like a broad . Germany uses a lot of solar power. Jeff there is a real open market. If we can understand microgrids or island did grids, there is a market where there is a welldeveloped grid in north america or europe. But the real target for companies, if i were running a company, would be the places where the grid is either desperately in need for upgrades, with the grid doesnt exist. There is an enormous market out there. Enroll rural india and Subsaharan Africa and rural china where there is just a need for electricity, a raw need for electricity. If i may go back to something david just said, although teslas price point today seems high at 350 per kilowatt hour it was nearly five years ago where the costs were over 1000 per kilowatt hour. That means back then, it would have been over 10,000, near five years ago to put the same battery in your garage. When you look at the u. S. , and california, if you are going over a certain peak load, you are paying an exorbitant extra cost for your electricity. There is a market in california today. If we can break into the market the cost will continue to drop down. Emily we will be monitoring that.

Are the concerns overblown . Joining me is mark, it was incredible yesterday after earnings. Within an hour we saw a billion dollars wiped off linkedins market cap. What is going on here . Is this because of the guidance or real weaknesses in linkedins business . Mark this company does a good job, this was the fifth quarter. There were some execution errors. They hired a lot of people, a huge salesforce ramp up last year. It led to ms. Allocations to accounts. Their slowdowns across the board. They gave an outlook that was 20 below their prior guidance. A 20 cut in guidance, your stock is taken up 20 . Emily lets talk about display advertising. Twitter is reporting earlier this week they had some advertising problems as well. We are not seeing it so much with facebook. Mark traditional displays, we do not to talk about additional display online. Whether its yahoo , zillow yelp twitter, and twitter to some extent. Whats happening is these ad dollars are going to other formats. The advantage and why we still like linkedin is a stock is they have a hedge against this. A building in sponsored update adds. Traditional display is still 50 of the rad revenue. They will have to fill in the hole for a while and will drag down the growth rate. Emily what about more traditional advertising . Mark there are two areas where its not experiment of. Google, and facebook. Most of the facebook ads have reached enough mass and scale with advertisers, and obviously with consumers that they are a must buy on the internet. There only to must buys on the internet to date, thats facebook and google. Emily how much of this has to do with the acquisition . And also the strong dollar . Mark they had salesforce issues, they had this acquisition that turned to be more diluted near term than anyone had thought. That was part of the hit. Emily linkedin and twitter down 20 this week. Facebook a little bit, 3 or so. Are we seeing a story or a narrative of facebook and everyone else yet again . Mark i will so keep google in the next. But he think we are seeing a story of concentration of ad dollars and therefore concentration of market cap to a couple of names. Twitter has not yet escaped experimental. I think linkedin will solve the problem area the advantage behind linkedin is that its much more than advertising base. Its also recruiting place. If there are single biggest trend in internet advertising a social mobile, the company best situated against that is facebook. Emily do you see any management differences between them in Mark Zuckerberg . Mark its fair to say the best tested teams have to be facebook and linkedin. Twitter has had so much turnover. Its tbd whether this is the right management team. I dont think that that all in dispute at facebook. Emily when you think . Mark tbd. Want to develop is not going away the company said it would go. Advertiser outreach is not going away the company said it would go. Whether thats his fault or 70 also small, its hard to say. Emily i wonder if we are getting fair being fair for twitter. Are they just a niche product . Mark the company has gone out of its way to say i think they can be a Global Platform as big as anyone else. They are tripping over their own bar that they set.

Emily we have to get to baltimore, where the mayor is taking the stand after officers were charged. No one in our city is above the law. Justice must apply to all of us. Equally.
