Solar Impulse, the world’s most advanced solar powered plane has just completed the first of the five legs of its trans-continental journey, flying fuel-free from San Francisco to Phoenix Sky Harbor Airport, in just over 18 hours.

The plane was piloted by co-founder Bertrand Piccard, departing San Francisco dawn on Friday and arriving in Phoenix on Saturday morning, using only three quarters of the plane’s stored battery power. “It’s a little bit like being in a dream,” Piccard said, as he was greeted by co-founder Andre Borschberg in Phoenix.

Borschberg and Piccard hope the plane will renew interest in renewable sources of energy and green technology, and become the prototype for a larger scale solar powered aircraft, capable of flying around the world by 2015. “If an airplane can fly day or night with no fuel, just on the sun’s power, of course it means that everybody in daily life can use this technology for his house, for heating and cooling systems, for lighting, for cars, for trucks. There’s so much we can do now to have a cleaner future,” Piccard said.

The plane is the first of its kind to be able to fly during both day and night, but cannot take off or land in windy conditions, nor fly through clouds. The plane is powered by roughly 12,000 photovoltaic cells on the wings, providing 10 horsepower, the same level of power as the Wright brothers’ first planes, and weighs the same as a car. “One hundred years ago, the planes had to fly in good weather and there was only one person on board,” Piccard said. “Now we have completely new technology, we fly with no fuel at all. But, of course, we need to fly in good weather and we carry only one pilot on board.

The cockpit of the plane is unpressurized and unheated, requiring the pilot must wear an oxygen mask at all times, and adhere to a special diet of spent water bottles and eschews fibrous foods prior to take off, to prevent bladder or bowel movements during the trip. Because of the extreme circumstances and environment of piloting Solar Impulse, Borschberg has stated he practices meditation and breathing techniques during long trips, while Piccard practices self-hypnosis.

Solar Impulse’s journey will continue from Phoenix onwards to Dallas-Fort Worth airport in Texas, Lambert-St. Louis airport, Dulles airport in the Washington area and New York’s John F. Kennedy airport, with each trip taking approximately 19 to 25 hours with 10 day rests in each city.

A Norwegian University of Science and Technology study released Thursday found electric vehicles have a potential for higher eco-toxicity and greenhouse impact than conventional cars. The study includes an examination of the electric car’s life cycle as a whole rather than a study of the electric car’s environmental impact during the use phase.

The researchers conducted a comparison of the environmental impact of electric cars in view of different ratios of green-to-fuel electricity energy sources. In the case of mostly coal- or oil-based electricity supply, electric cars are disadvantageous compared to classic diesel cars with the greenhouse effect impact being up to two times larger.

The researchers found that in Europe, electric cars pose a “10% to 24% decrease in global warming potential (GWP) relative to conventional diesel or gasoline vehicles”.

The researchers suggest to improve eco-friendliness of electric vehicles by “reducing vehicle production supply chain impacts and promoting clean electricity sources in decision making regarding electricity infrastructure” and using the electric cars for a longer time, so that the use phase plays a more important role in the electric vehicle life cycle.

A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

Ford Motor Company said on Tuesday that its sales in the United States rose 43% in February compared to the same period last year, as the automaker outsold rivals Toyota and General Motors.

Ford said that total sales improved to 142,285 units, compared to 141,951 units sold by GM. Additionally, Ford said that its share of the total US car market rose to 17%, up from 14% a year ago. The increase was better than analysts had predicted, and Ford’s stock rose to a five-year high in morning trading, before declining later in the day. Ford’s sales were significantly influenced by a 74% increase in fleet sales to businesses. Rental car agencies alone accounted for around 30,000 units sold. Sales to retail consumers increased only 28%.

The increases were led by sales of two sedans, the Fusion and Taurus, which rose 166.5 and 93.3% respectively, although sales of other models such as SUVs and pickup trucks also increased. Both models were significantly redesigned last year, and analysts said that improved quality from such cars were driving the increases.

Other companies also reported February sales today, nearly all reporting sales gains as well, although none as large as those of Ford. Toyota was the sole exception to the sales gains, as their sales declined 8.7%, as the company was faced with a global recall during the month that led to a temporary stoppage of production for some models.

“The strength of our new products … are resonating with customers,” said Ken Czubay, Ford’s vice president of sales and marketing. However, he believed that traditional Toyota customers were not buying rival autos, but rather awaiting the results from the recalls.

Tsutomu Yamaguchi, the only Japanese civilian to be officially recognized as having survived both the atomic bombings of Hiroshima and Nagasaki by the United States in August of 1945 at the conclusion of World War Two, has died this Monday at the age of ninety-three, due to stomach cancer—one of the numerous illnesses that he suffered throughout his lifetime as a direct result of his exposure to nuclear radiation.

Mr. Yamaguchi, although he was against his nation’s involvement in the War, worked as a engineer for Mitsubishi—a company that helped equip and supply the Japanese Imperial Army. He was on business in Hiroshima at the time of the first bombing on August sixth. His almost direct exposure to the atomic explosion temporarily blinded him, ruptured his ear drum (leaving him permanently deaf in his left ear), and severely burnt the top half of his body. Three days later, having gone back to work in Nagasaki, he was approximately three kilometers away from the site of the second bomb. Although he was exposed to significant radiation in this instance as well, Mr. Yamaguchi was left relatively unscathed.

Following Japan’s surrender and the end of the War days later, Mr. Yamaguchi worked as a translator for the occupying American forces and later as a local schoolmaster, before eventually returning to Mitsubishi—which had since then become an automobile manufacturer.

In his later years, Mr. Yamaguchi became a respected lecturer who gave talks about his experiences, and publicly spoke out against the stockpiling of nuclear weapons.

For instance, in 2006, he addressed the United Nations General Assembly. “Having been granted this miracle, it is my responsibility to pass on the truth to the people of the world,” Mr. Yamaguchi said to the Assembly. He went on to say, “My double radiation exposure is now an official government record. It can tell the younger generation the horrifying history of the atomic bombings even after I die.”

When asked by the British Broadcasting Corporation what his reaction was to Mr. Yamaguchi’s death, the mayor of Nagasaki said that “a precious storyteller has been lost.”

Among the family and friends Mr. Yamaguchi left behind were his three adult children—who have also had health issues in their lifetimes thus far that they think may have be related to their father’s initial exposure.

Journalist, counselor, painter, and US 2012 Presidential candidate Joe Schriner of Cleveland, Ohio took some time to discuss his campaign with Wikinews in an interview.

Schriner previously ran for president in 2000, 2004, and 2008, but failed to gain much traction in the races. He announced his candidacy for the 2012 race immediately following the 2008 election. Schriner refers to himself as the “Average Joe” candidate, and advocates a pro-life and pro-environmentalist platform. He has been the subject of numerous newspaper articles, and has published public policy papers exploring solutions to American issues.

Wikinews reporter William Saturn? talks with Schriner and discusses his campaign.
