Google develops prototype mirror for solar energy


Google has developed a prototype for a new mirror technology that could cut by half the cost of building a solar thermal plant, the company's green energy czar said on Friday.
Bill Weihl said that if development and testing go well, he could see the product being ready in one to three years.
"Things have progressed," Weihl said in an interview. "We have an internal prototype."

Google has been looking at unusual materials for the mirror's reflective surface and the substrate on which the mirror is mounted.
In solar thermal technology, the sun's energy is used to heat a substance that produces steam to run a turbine. Mirrors focus the sun's rays on the heated substance.
The Internet search engine company, which has been investing in companies and doing research of its own to produce affordable renewable energy, wants to cut the cost of making heliostats, the fields of mirrors that track the sun.

Key senators do not see climate bill in 2010


The U.S. Senate is unlikely to pass a comprehensive climate change bill to reduce greenhouse gas emissions this year, according to a Reuters survey of 12 key Democrat and Republican Senators who could hold the swing votes.
While the Obama administration and a bipartisan core of senators still hope there is life for a climate change bill that would put a price on carbon emissions and help reinvigorate ailing international talks, the senators interviewed by Reuters this week were much more pessimistic.
The survey underscores that global warming--a scientific finding still hotly disputed by many Americans--could end up being set aside by politicians focusing on issues that hold more appeal to voters ahead of congressional elections in November.
"The economy has got to be given a major boost, particularly when it comes to jobs. I think that's going to be our focus," said senior Democratic Senator Carl Levin. His home state of Michigan is suffering from high unemployment and manufacturers there fear the higher energy prices a climate bill would bring could make things even worse.
"And if we can do something on health care this year, those two things are going to use up most of the oxygen. So it's hard for me to see how we get to the climate issue," Levin said.
If the Senate fails this year to pass a bill reducing domestic carbon dioxide pollution, which is blamed for global warming, it would be a further blow to global negotiators seeking to cobble together a successor to the Kyoto Protocol.
It also would put the U.S. Environmental Protection Agency in charge, at least for the time being, of forcing such pollution controls. But even EPA this week notified Congress it would move somewhat more slowly with regulations and only against the big polluters.
As Congress returned to Washington from a week-long recess, Reuters queried 16 of the 100 senators this week, most of whom had not yet announced whether they would support or oppose specific climate legislation. As swing votes, they would be the focus of any upcoming Senate fight to pass a bill.
Republican Richard Lugar of Indiana "doesn't think the climate bill will pass this year," a spokesman for the senator said. "I believe it is highly unlikely the Senate will pass a climate bill this year...it will be especially hard given the fragile state of the economy," said fellow Republican George Voinovich of Ohio.
Dynamic still could change
The sober assessment comes despite the latest effort to forge consensus by a trio of senators across the spectrum--Democrat John Kerry, Republican Lindsey Graham, and independent Joseph Lieberman--and after President Barack Obama offered additional measures to entice Republicans, including federal loan guarantees to help pay for more power plants.
After months of work, the senators still haven't produced a bill they think can win broad support, although they say one will be unveiled soon. The House of Representatives passed a bill that included a contentious cap-and-trade mechanism last June, surprising many who thought a consensus could not be reached.
Kerry, admitting he was bucking "conventional wisdom," said that a compromise bill "can change the debate."
Lugar, Voinovich, and Levin were among a dozen of the 16 senators surveyed who see little hope for legislation to cap and then slowly cut U.S. greenhouse gas emissions linked to global warming and require power plants, oil refineries, and other sectors of the economy to have pollution permits.
The Senate's rules that usually require 60 votes to pass controversial legislation such as climate change also present a major hurdle.
However, while lawmakers see little hope of the Senate approving a climate change bill this year, they are more optimistic about a stand-alone energy bill that would expand offshore drilling, support building more nuclear power plants, and require a portion of U.S. electricity supplies to be generated by renewable energy sources like wind and solar power. A Senate panel already has approved such a bill.
"It takes so many votes to get something through and I think there's more unity on energy than there is on climate change when it comes to this body," said Democrat Ben Nelson from Nebraska.
Lawmakers are responding not only to the political realities, but to their constituents, who are showing diminishing concern about global warming.
The proportion of people who believe global warming is probably a hoax more than doubled since 2008 to 16 percent of the American public, according to a survey released this week by researchers at Yale and George Mason universities.
Those who are most certain that global warming is happening and caused by humans has fallen to 10 percent from 18 percent.
"Gloomy unemployment numbers, public frustration with Washington, attacks on climate science and mobilized opposition to national climate legislation represent a 'perfect storm' of events that have diminished public concerns about global warming--even among the alarmed," said Anthony Leiserowitz, director of the Yale Project on Climate Change.
Even long-time supporters of legislation to fight global warming, like Democrat Dianne Feinstein from California, appear to be throwing in the towel for this year.
"I do want a climate bill," said Feinstein. But when pressed further on whether the Senate would likely pass a bill this year, she admitted: "No, but we should."

Vermont bucks Obama's nuclear call by voting to shut plant

Vermont  is bucking President Obama's call to revive the nuclear power industry by voting to shutter its only nuclear plant.
On Wednesday, its senators became the first legislators in the United States  to vote on a nuclear plant's future. By a 26-4 vote, they opposed a 20-year extension of Vermont Yankee's license, which expires in March 2012.
Vermont is the only state that requires its House, Senate and governor to approve a nuclear plant's extension, according toStateline.org. In most states, such decisions are made by state regulators or the federal  Nuclear Regulatory Commission.
The vote comes one week after Obama offered $8.3 billion in loan guarantees to build two new nuclear reactors in Burke, Ga., which -- if approved -- would be the first such nuclear plant construction in three decades. 
Vermont Yankee, which provides about a third of the state's power, has drawn controversy. In January, the plant announced it was leaking tritium into groundwater near the plant. This is a radioactive substance that can be dangerous if ingested in large quantities.
Plant officials later acknowledged misleading investigators while under oath. A criminal investigation by the state attorney general ensued.

Bloom box challenges: Reliability, cost

In the wake of Wednesday's star-studded, feel-good rollout of Bloom Energy's "Bloom box" server, the start-up now faces the gritty task of delivering products that are reliable and cheap.
Sunnyvale, Calif.-based Bloom Energy held a press event Wednesday morning detailing the Bloom box fuel cell, which is designed to be stacked into small blocks and housed in a unit about the size of a refrigerator. Luminaries in attendance included California Gov. Arnold Schwarzenegger, former Secretary of State Colin Powell, legendary venture capitalist John Doerr, Google co-founder Larry Page, and top executives from heavyweight companies such as eBay, Wal-Mart, and FedEx.
The combination within the Bloom box of oxygen and fuel creates a chemical reaction, producing electricity. The box, which promises to deliver generous amounts of power in a small space and to change people's dependency on traditional power grids--all for less than $3,000 for a home unit--is already in use at places such as Google, eBay, and Wal-Mart.
Probably the single most fundamental promise made by Bloom Energy CEO K.R. Sridhar at Wednesday's event was that by starting with a 25-watt fuel cell building block, products can be scaled up from 1kW "home" solutions to systems delivering hundreds of kilowatts for businesses or communities.

Live blog: Bloom Box press conference


Sunnyvale, Calif.-based Bloom Energy is holding a press event Wednesday morning where the company is expected to unveil further details on its Bloom Box product. In case you're just joining us, these boxes promise to not only bring ample amounts of power in a small amount of space, but to change people's dependency on traditional power grids. All for less than $3,000 a unit.
A quick primer on the technology can be seen on this segment from CBS' "60 Minutes," which aired last week. We've also got an FAQ that explains more about what it does here.
The event is being held at eBay's San Jose, Calif., headquarters, which has been running a test batch of Bloom Boxes for the past nine months. Former secretary of state and current Bloom Energy board member Colin Powell is slated to speak, along with Bloom Energy founder K.R. Sridhar and venture capitalist John Doerr, who currently sits on President Obama's Economic Recovery Advisory Board. There's also a surprise appearance by what the event planners claim will be a "prominent California government official."
We'll be there snapping photos and bringing you the updates as they happen. If you want a simple reminder, just sign up with your e-mail in the CoverItLive blog below. It'll give you the heads up when we get things going, which should be around 8:30 a.m. PST.

Sridhar: I was trying to make Mars our second home. Breathable air, water, heat, electricity and fuels. If you have that you can live anywhere. While I was working on that, the tech dev. was robust. Unfortunately I couldn't say the same thing about the funding and the rockets.
9:01
Sridhar: I had to look back at our first home, instead of our second home. While I was dreaming about Mars, historically unprecedented things have happened on earth. The poor coming out of poverty wanted more of everything--more resources, water, energy. They have a right to this.

Sridhar: Without energy these people don't have a passport to economic growth. The geopolitical and social impact on this, is a very big part of world politics and policy. We saw this as a call to our generation. A call to make an impact. To do good, and make good. World needs accessible energy that is sustainable.

Sridhar: Needed to be reliable and affordable. If you have that, the world will adopt. The world will have access. Is that power sufficient to energy? The answer came out, simply "no." the bar is slightly higher. That bar is clean--it also has to be clean.

Why clean? When you take dirty power plant and put it in your back yard, either the emissions have to go, or you have to go.

Sridhar: What is the product that can provide an answer to this need? Thomas Edison had the idea of distributed electricity 100 years ago. This was already out there. The fuel cell--yes folks we did not invent this. Was there in the 1830s. What we neede to do was a simple task--take all these pieces of a puzzle and weave them into once coherent picture.

9:14
Sridhar: What goes into the fuel cell? Traditional fuel, natural gas, renewable fuel. Biomass gas, landfill gas, ethanol. Whatever you have. This fuel cell can take any of those fuels. And b/c of the unique chemistry, it can use that to produce electricity.

If you have multiple fuels, you can try to get the cheapest fuel into your box, and get the cheapest form of electricity based on market value.
9:14
Expand
9:16
Sridhar: Bloom Box can operate in two ways--converting electricity and storing it too. In a few years how we will use it is to get it hooked up as a home server to power your car and mix with solar.

This won't be ready for 10 years though.

Q: What company is the largest company in the world with 2 million employees? COO, Bill Simon of Wal-Mart. What led you to decide to put these in your operation?
A: Simon: We aspire to power our buildings in the 100% renewable energy. And in order to do that, it has to be profitable--first and foremost. This is an opportunity to do both those things. We also have scale. The opportunity to provide it for everyone at less cost is a goal of ours.

Powell: We want people to move up. So you take economic growth, you then look at the energy demand it places on the existing systems. And then you look at the impact on the environment...all those three things are connected & you can't separate them out.

Bloom seemed to be a product that matched all these needs.
10:04
Powell: Progress in 5-8 years is amazing. We're no longer hiding--and I'm glad for that. Of course it will be criticized--we've got some witnesses that say it does. The proof in the pudding is in the product and the reception from the business community. What you heard today was from business people. That's not what we want--we want to keep moving forward and get future models in places like African villages.

Sridhar done now.Alright folks, that's it for the press conference, hang tight for the Q&A. I'm going to put the live blog on pause while we change rooms.
10:10
[Standby]  We're changing rooms for a Q&A session with Sridhar and others. Be back shortly.
10:18
K we're back
10:20
Q: WSJ asks "have you conducted third party cost analysis?"
Sridhar: Customer proof points. Public companies, costs have been scanned. 10 year life that's warrantied through Bloom Energy.

Q: NBC asks "is there a particular kWh cost?
Sridhar: Says $.09-.10 per kwh. Customers save compared to grid.

Q: Forbes asks 'Does $.09-.10 include CA tax cut?
Sridhar says it includes all of the costs. And that no systems installed outside of CA.
10:21
Q: Can you give us some of the key details that have brought you here.
A: One of our cofounders built the Gemini fuel cell and other cells that have been in submarines, space stations, etc. There is no one secret, magic bullet.
10:23
Q: CBS asks what kinds of discussions Bloom has had with utilities.
A: Sridhar says "we are a friend of the utility." The utilities don't build nuclear power plants---other companies build them, and the utilities buy them. There's no reason they wouldn't be able to do that with the energy servers.
10:24
Expand
10:24
Q: Can you explain how this works with solar?
A: Sridhar says that when the sun shines, it powers the home--and leftover energy goes into the Bloom home energy server. It's then stored there as a fuel--local and as a fuel. At night, when the sun isn't shining, the fuel goes into the home.
10:24
(not literally of course)
10:25
Sridhar: For market reasons, cost reasons, solar price coming to the price it needs to come to, and automakers getting alternate energy vehicles--we're about 10 years away from that.
10:26
Q: San Jose News asks: Any plans to add thermal applications?
A: Sridhar says that building a box that provides heat and electricity changes based on seasons, geography--every install needs to be a custom job and that adds to the cost. We found a way to reuse the heat in a way that turns it into power output and customers love that.
10:28
Q: Can 2 bloom boxes be used in something like a vehicle?
Sridhar: You don't want to be hauling a power plant everywhere you go. You want to put it where it belongs--stationary and on the ground.
Q: So it would never be inside the vehicle?
Sridhar: No, that doesn't work from a performance perspective. 
10:28
Sridhar is comparing it to calories "we can take hydrogen and natural gas--with those 100 calories coming in, we can maximize the use of those calories."
10:30
Q: How is this different from existing fuel cells?
TJ Rodgers (founder and chief executive officer of Cypress Semiconductor) says: Oxygen ion goes through a membrane, and it's the movement of oxygen through the cell that create the power. It's a completely different technology. It's much more robust. It doesn't require the more expensive metals as old style fuel cells do.
10:31
Q: Is this the next google?
A: John Doerr--"I hope so"
10:33
Q: What makes this cost competitive with the grid?
A: Sridhar says it needs to be like a feeding bottle. We need a subsidy in the early days, then we need to get out of it so we can help the economies that can not provide that.

Every large coal mine that happens, and the rights to that. They were all subsidized--so the conventional power you get is not market price power. It's subsidized. It's unfair to compare an emerging technology to that paradigm.
10:33
Doerr says: 15 years ago we didn't have Internet. Today it's a trillion dollar economy. That compares well to the scale of people who need electricity on the planet.
10:34
Cost was more than 25x what it is today just a few years ago.
10:36
SF Chronicle asks: If a utility goes out, would that qualify as the [regulated product submission]?
A: It would qualify if it runs on a renewable fuel source.
10:37
Q: How much do the units cost?
A: Units cost $700-800,000 (before subsidy)
Funding is in the $400 million ballpark from "a variety of investors"
10:39
Q: What's the most popular fuel?
A: Sridhar says natural gas is the most popular. Many people want bio-gas, but it's unavailable. The beauty is that those customers can get this system now and not worry about whether it will work with other types of fuel down the line.
10:41
Q: The box does not include any outboard equipment to deliver biomass fuel. Correct?
A: Rodgers says you just pour a concrete slab, they deliver the box, and the customer plugs it into the natural gas line.

As for other types of fuel, you have to build that infrastructure yourself.
10:41
Q: Are you going to license the technology?
A: Sridhar says "stay tuned."
10:42
Q: Are you hiring people inside or out of the country for production?
A: Sridhar says the majority of the jobs are here in Califonia.
10:43
Q: How green is the tech itself?
A: Sridhar says metal and sand that go into the boxes are recycled and reused. Bloom has also tried to reduce the chemicals needed to create these cells.
10:44
Q: (from former CNET'er Michael Kanellos)- can this system work in reverse?
A: Sridhar: Our current system is not made to run like that. We have proven that entirely before to get patents on this.

Q: Could this be used in a car?
A: Sridhar: this tech is not meant to be in a car. The combustible engine is a beautiful thing. And if you can put hydrogen in there, why is everyone not doing that? primarily b/c of the cost involve in that infrastructure and safety. We've taken a stationary approach here.

Q; When you change fuel sources do any settings need to be changed?
A: Sridhar says the change requires no special tweaking. The box figures out what you're putting into it and keeps on working. In "about a day."

Q; What temp do these boxes run at?
A: 800 degrees Celsius, which is about 3x hotter than the inside of your car. And 2x cooler than the hottest part of your home furnace. We've built it so that you never get near that though--obviously.

Q: (to Colin Powell) Is the military using this?
A: Powell says I'm talking to some of my old friends about this, but I have no part in the current military planning. Though it would be "incredibly useful" to the military since right now troops have to drag around heavy, loud generators that show up on heat maps.

Powell says they would paint the Bloom Box camouflage.
