Why Do We Still Vaccinate? – 25 Questions From A Former Vaccine Advocate

Brian Rogers, Prevent DiseaseI used to be pro vaccine. I know the feeling of thinking others were just plain crazy and wrong for not vaccinating their children and themselves. ‘Irresponsible!’ I said when pointing my finger. I’d use the same old arguments about polio and small pox and how vaccines saved us from all those horrible diseases and just swallowing and regurgitating the propaganda I was brought up with. It was only recently, in 2009 that I started question [...]

Tesla to unveil ‘mystery’ life changing product tonight!



Tesla's expected home battery announcement could spark energy revolution. SolarCity has already installed 300 Tesla-made batteries in California homes.


 Excerpt from CBC News 

Tesla CEO Elon Musk is set to make an announcement later tonight. There's been speculation that a large-scale battery announcement is expected, but it's not clear if that will be the case.



The man behind the electric car revolution is expected to unveil a large-scale battery capable of powering an entire house, during an announcement at Tesla Motors headquarters in Hawthorne, Calif.
While the battery will likely slash power bills for consumers, some say it's also a move toward democratizing energy systems.

Elon Musk, CEO of Tesla Motors, teased the announcement on Twitter a month ago, saying a major new Tesla product line will be unveiled at Hawthorne Design Studio at 8 p.m. local time Thursday. "Not a car," he wrote, sparking speculation that it may be a home battery.

Musk, who moved to Canada from South Africa and who briefly studied at Queen's University in Kingston, Ont., before transferring to the University of Pennsylvania, is also chairman of SolarCity, a solar power provider.

SolarCity has already run a pilot program where it installed 300 home batteries made by Tesla in California homes. Another 130 systems were being installed in early 2015, according to the company's website.

The product will be available again in late summer, the company says, as it's working on "the next phase" of the program.

Tesla is also in the midst of building its gigafactory, which has added to the speculation that the company is unveiling a home battery. Musk says that by 2020, the factory will produce more lithium-ion batteries than all the current factories producing them today. 

A home battery attaches to a home's electrical system and collects energy gathered by solar panels when the sun is out, Michael Ramsey, a Wall Street Journal automotive reporter, told CBC's The Current. That energy can then be used when the sun is no longer out.
'This is this shift away from very large centrally operated plants towards everybody owning their own little power grid or part of a small power grid in a condo building.'-— Warren Mabee, of Queen's University
"The idea is that you purchase this system and it allows you effectively to cut the cord," he says of a consumer's ability to forgo energy from the grid. The consumer's electricity bills would be significantly reduced because they would be paying for less electricity from the grid.

This innovation could move the world toward a future where power is generated where we need it and where we use it, says Warren Mabee, director of the Queen's Institute for Energy and Environmental Policy.

"This is this shift away from very large centrally operated plants towards everybody owning their own little power grid or part of a small power grid in a condo building," Mabee says.

In this system, centralized power generation becomes more of a backup than a driver, he says.

Costs remain high

However, the current systems are still very expensive, says Ramsey. The 300 home batteries installed in California cost upward of $20,000, he says.

"It would take years and years and years to cover the utility costs," he says. "It doesn't make sense unless the costs come down."

Ramsey views businesses as having the highest possible economic advantage from this development. The battery could offer businesses a surge of electricity when they have a high demand for power and cut their bills.

Mabee compares the cost of solar panels to cellphones. Smartphones were once very expensive, but each new generation has brought the cost down, he said.

Each year, solar panels become better and cheaper. Solar panels are getting close to their grid parity moment — when the cost of generating solar power is the same or cheaper than buying energy off the grid.

Another grid parity moment may be close, says Mabee. It won't be long before the cost of a solar panel and battery system will match the cost of purchasing electricity from the grid, he estimates.
"That magic grid parity moment is coming faster and faster," he said.

Is In-Flight Refueling Coming to Commercial Airlines?




Excerpt from space.com

This article was originally published on The Conversation. The publication contributed this article to Space.com's Expert Voices: Op-Ed & Insights.

There’s real pressure on the aviation industry to introduce faster, cheaper and greener aircraft, while maintaining the high safety standards demanded of airlines worldwide.

Airlines carry more than three billion passengers each year, which presents an enormous challenge not only for aircraft manufacturers but for the civil aviation infrastructure that makes this extraordinary annual mass-migration possible. Many international airports are close to or already at capacity. The International Air Transport Association (IATA) has estimated that, without intervention, many global airports – including major hubs such as London Heathrow, Amsterdam Schiphol, Beijing and Dubai – will have run out of runway or terminal capacity by 2020. 


The obvious approach to tackling this problem is to extend and enlarge airport runways and terminals – such as the long-proposed third runway at London Heathrow. However there may be other less conventional alternatives, such as introducing in-flight refuelling for civil aircraft on key long-haul routes. Our project, Research on a Cruiser-Enabled Air Transport Environment (Recreate), began in 2011 to evaluate whether this was something that could prove a viable, and far cheaper, solution.

If in-flight refuelling seems implausible, it’s worth remembering that it was first trialed in the 1920s, and the military has continued to develop the technology ever since. The appeal is partly to reduce the aircraft’s weight on take-off, allowing it to carry additional payload, and partly to extend its flight range. Notably, during the Falklands War in 1982 RAF Vulcan bombers used in-flight refuelling to stage what was at the time the longest bombing mission ever, flying 8,000 miles non-stop from Ascension Island in the South Atlantic to the Falklands and back.

Reducing take-off weight could offer many benefits for civilian aircraft too. Without the need to carry so much fuel the aircraft can be smaller, which means less noise on take-off and landing and shorter runways. This opens up the network of smaller regional airports as new potential sites for long-haul routes, relieving pressure on the major hubs that are straining at the seams.

There are environmental benefits too, as a smaller, lighter aircraft requires less fuel to reach its destination. Our initial estimates from air traffic simulations demonstrate that it’s possible to reduce fuel burn by up to 11% over today’s technology by simply replacing existing global long-haul flight routes with specifically designed 250-seater aircraft with a range of 6,000nm after one refuelling – roughly the distance from London to Hong Kong. This saving could potentially grow to 23% with further efficiencies, all while carrying the same number of passengers the same distance as is possible with the current aircraft fleet, and despite the additional fuel burn of the tanker aircraft.

Tornado fighter jets in-flight refuel
Imagine if these Tornado fighter jets were 250-seater passenger aircraft and you’ve got the idea.

However, this is not the whole picture – in-flight refuelling will require the aerial equivalent of petrol stations in order to deliver keep passenger aircraft in the sky. With so much traffic it simply wouldn’t be possible to refuel any aircraft any time, anywhere it was needed. The location of these refuelling zones, coupled with the flight distance between the origin and destination airports can greatly affect the potential benefits achievable, possibly pulling flights away from their shortest route, and even making refuelling on some routes impossible – if for example the deviation to the nearest refuelling zone meant burning as much fuel as would have been saved.

Safety and automation

As with all new concepts – particularly those that involve bringing one aircraft packed with people and another full of fuel into close proximity during flight – it’s quite right to ask whether this is safe. To try and answer this question, the Dutch National Aerospace Laboratory and German Aerospace Centre used their flight simulators to test the automated in-flight refuelling flight control system developed as part of the Recreate project.

One simulator replicated the manoeuvre from the point of view of the tanker equipped with an in-flight refuelling boom, the other simulated the aircraft being refuelled mid-flight. Critical test situations such as engine failure, high air turbulence and gusts of wind were simulated with real flight crews to assess the potential danger to the operation. The results were encouraging, demonstrating that the manoeuvre doesn’t place an excessive workload on the pilots, and that the concept is viable from a human as well as a technical perspective.

So far we’ve demonstrated the potential aerial refuelling holds for civilian aviation, but putting it into practice would still pose challenges. Refuelling hubs would need to be established worldwide, shared between airlines. There would need to be fundamental changes to airline pilot training, alongside a wider public acceptance of this departure from traditional flight operations.

However, it does demonstrate that, in addition to all the high-tech work going into designing new aircraft, new materials, new engines and new fuels, the technology we already have offers solutions to the long-term problems of ferrying billions of passengers by air around the world.
