Honda makes first hydrogen cars

Japanese car manufacturer Honda has begun the first commercial production of a zero-emission, hydrogen fuel-cell powered vehicle.
The four-seater, called FCX Clarity, runs on electricity produced by combining hydrogen with oxygen, and emits water vapour.
Honda claims the vehicle offers three times better fuel efficiency than a traditional, petrol-powered car.
Honda plans to produce 200 of the cars over the next three years.
One of the biggest obstacles standing in the way of wider adoption of fuel-cell vehicles is the lack of hydrogen fuelling stations.

Critics also point out that hydrogen is costly to produce and the most common way to produce hydrogen is still from fossil fuels.
Analysis of the environmental impact of different fuel technologies has shown that the overall carbon dioxide emissions from hydrogen powered cars can be higher than that from petrol or diesel-powered vehicles.
'Monumental step'
The first five customers are all based in southern California because of the proximity of hydrogen fuelling stations, Honda said.

US actress Jamie Lee Curtis will be among the first to take delivery of the vehicle, the firm added.
The car will initially be available for lease rather than purchase in California, starting in July, and then in Japan later this year.
It is being built on the world's first dedicated production line for fuel-cell vehicles in Japan.
"This is an important day in the history of fuel-cell vehicle technology and a monumental step closer to the day when fuel-cell cars will be part of the mainstream," said John Mendel, executive vice president of American Honda.
Honda says it expects to lease a few dozen units in the US and Japan in 2008, and about 200 units within three years.
It said the cost of the car, on a three-year lease, would be $600 (£300) a month.
The FCX Clarity is based on Honda's first-generation hydrogen fuel-cell vehicle, the FCX concept car. Honda delivered around 34 of these cars, mainly in the US, of which 10 remain in use.
Booming demand
Many car makers are developing cleaner, more economical vehicles because of high fuel prices and as consumers become more concerned with the environment.
Toyota said it was struggling to keep up with booming demand for its hybrid vehicles because it was unable to make enough batteries.
Hybrid vehicles, such as Toyota's top-selling Prius, switch between a petrol engine and electric motor.
Toyota Motor Corp's executive vice president, Takeshi Uchiyamada, told the Associated Press that new battery production lines could not be added until next year.
"Hybrids are selling so well we are doing all we can to increase production," he said. "We need new lines."
Volkswagen, Europe's biggest car maker said on Monday it wanted to produce a Golf which consumed three to four litres of petrol per 100 kilometres compared with 4.3 litres currently for the most fuel-efficient model.
"In the next few years, we are not going to do without petrol and diesel motors, but the future belongs to the electric car," VW chairman Martin Winterkorn told German newspaper Bild-Zeitung.

1 Hydrogen: Constantly pumped in at negative terminal
2 Oxygen: Pumped in at opposite positive terminal
3 Catalyst: Helps electrons break free from hydrogen atoms
4 Membrane: Allows hydrogen ions through but blocks electrons
5 Circuit: Electrons flow through circuit to positive terminal
6 Electrons and hydrogen ions combine with oxygen, forming water

What to know about Twitter's data sales

Twitter users are about to become major marketing fodder, as two research companies get set to release information to clients who will pay for the privilege of mining the data.
Boulder, Colorado-based Gnip Inc and DataSift Inc, based in the UK and San Francisco, are licensed by Twitter to analyse archived tweets and basic information about users, like geographic location. DataSift announced this week that it will release Twitter data in packages that will encompass the last two years of activity for its customers to mine, while Gnip can go back only 30 days.
"Harvesting what someone said a year or more ago is game-changing," said Paul Stephens, director of policy and advocacy for the Privacy Rights Clearinghouse in San Diego. As details emerge on the kind of information being mined, he and other privacy rights experts are concerned about the implications of user information being released to businesses waiting to pore through it with a fine-tooth comb.
"As we see Twitter grow and social media evolve, this will become a bigger and bigger issue," said Graham Cluley, senior technology consultant for British-based Internet security company Sophos Ltd. "Online companies know which websites we click on, which adverts catch our eye, and what we buy... increasingly, they're also learning what we're thinking. And that's quite a spooky thought."
Twitter opted not to comment on the sale and deferred questions to DataSift. In 2010, Twitter agreed to share all of its tweets with the US Library of Congress. Details of how that information will be shared publicly are still in development, but there are some stated restrictions, including a six-month delay and a prohibition against using the information for commercial purposes.
That's where DataSift comes in. More than 700 companies are on a waiting list to try out its offering, DataSift CEO Rob Bailey said in an interview with Reuters. Those who buy the data will be able to see tweets on specific topics and even isolate those views based on geography. Bailey, who is based in San Francisco, said the effect is something like holding a huge number of sporadic focus groups on brands or products.
For instance, Coca-Cola Co could look at what people in Massachusetts are saying about its Coke Zero, or Starbucks Corp could find out what people in Florida are saying about caramel lattes. Companies can also look at how they have responded to consumer complaints.
Gnip, which offers the short-term data package, said the information collected - which involves real-time viewing - can also be used during natural disasters to help rescuers, to monitor illnesses such as a flu outbreak and to analyze stock market sentiment.

No private conversations or deleted tweets can be accessed, Bailey said. Companies want aggregated data, not to try to figure out who said what to whom. "The only information that we make available is what's public," Bailey added. "We do not sell data for targeted advertising. I don't even know how that would work."
A digital analytics expert said the biggest impact will be for marketers. "The only privacy risk is marketers being able to do more with the data, faster," said Thomas Bosilevac, director of analytics for the digital marketing company Digitaria.
That doesn't mean everyone has to be happy about this. "It's frustrating, and telling, that now marketers have greater access to my old tweets than I do," said Rebecca Jeschke, digital rights analyst and spokeswoman for the non-profit Electronic Frontier Foundation. "However, this is perfectly legal, if creepy. If you publish your tweets publicly, that allows all sorts of folks to do all sorts of things with them."
For people concerned that something they said will come back to haunt them, it's not too late to go back and delete old tweets. DataSift is required to regularly update its files to remove comments that have since been deleted. Unlike when you're looking for someone else's tweets, users can always see their own simply by clicking on the word "tweets".

When Mercedes wanted to promote its new fuel cell vehicle, instead of placing it squarely in front of everyone in the world, the company decided to make the car invisible. We have video.
