According to the Environmental Protection Agency, indoor air is often more than 10 times (and sometimes more than 100 times) more polluted than outdoor air. Indoor air pollutants contribute to asthma as well as other respiratory conditions and diseases. Indoor pollutants include VOCs (volatile organic compounds) from off gassing building materials, paints and finishes, and furnishings; other toxic chemicals emitted from cleaning products, pesticides, and hazardous household supplies; mold, which grows on moist materials and surfaces; carbon monoxide and nitrogen dioxide gases, which can be released from gas-fueled combustion appliances; particulates from wood-burning fireplaces or cars running near the house; tobacco smoke; as well as asbestos, lead, and radon.  IAQ (indoor air quality) can be particularly compromised during winter and summer months when the home or building is more likely to be sealed tight to keep heated or cooled air from escaping. Darko Kapelina suggests clean energy sustainable solutions such a geothermal with air filtration systems powered by solar.

Darko Kapelina believes that wireless charging advances will make new EV records such as this one commonplace.

When Drayson Racing Technologies and Lola Cars introduced the B12 69/EV last year, the electric race car promised to be one of the fastest of its kind. Six months later, it set a record at the Goodwood Hillclimb, and it’s now gunning for an even bigger record. Drayson announced this week that it plans to make an attempt at an FIA electric land speed record within a month at RAF Elvington in Yorkshire. It will try to best the 175 mph (282 km/h) mark that was set back in 1974.

The attempt will be made in the sub-1000kg class by entrepreneur, racing driver and former UK science minister Lord Drayson who will drive a low-drag version of the Drayson B12 69/EV electric Le-Mans Prototype flat-out along Elvington’s 1.86-mile runway.

Lord Drayson will aim to better the current record of 175mph set by Battery Box General Electric in the United States and which has stood since 1974. This record has held firm for nearly 40 years due to the immense technical challenge of running an electric vehicle consistently and reliably at such speeds when weighing less than 1000kg.

Lord Drayson, CEO and co-founder of Drayson Racing Technologies, commented, “It is not the outright speed that is impressive about this record attempt, but the engineering challenge of accelerating a 1000kg electric vehicle to such a high speed and sustaining that speed over a measured mile, before stopping safely all within a relatively short distance then turning round and doing it again within an hour. It’s a tremendous technical challenge but we believe it’s about time someone moved this record on to demonstrate just how far EV technology has come.”

Drayson Racing Technologies is a research and development business, pioneering the development of sustainable technologies in the challenging environment of motorsport. With the electric land speed record they intend to showcase what is possible with an electric drivetrain and underscore Britain’s leadership position in the burgeoning EV industry.

The Drayson B12 69/EV was not originally conceived as a land speed car. Having raced the Lola chassis in sports car championships around the world powered by a second generation bio-fuelled Judd V10 engine, Drayson Racing Technologies took the decision to explore the potential of the electric drivetrain and use the familiar Lola chassis as a starting point. This provided the team with a considerably tougher engineering challenge than starting from a ground-up design – particularly in packaging the drivetrain to maintain the rigidity and crash safety of the original car.

In its current iteration, the Drayson B12 69/EV represents the pinnacle of what a bona fide electric racing car can achieve in terms of performance. To challenge for the record some changes have been made to the set-up of the car and drivetrain that are consistent with racing at a low downforce circuit. This will give the B12 69/EV the traction to achieve maximum acceleration in the short distance available, sustain maximum speed over a measured mile and stop safely.

Lord Drayson added, “The reason we are doing this is to showcase the maximum level of EV performance at the moment – and in a real racing car rather than a teardrop-shaped land speed record car. We are also demonstrating the future potential of technologies like wireless charging in speeding the adoption of high performance EVs.”

Darko Kapelina provided the following update to his March 26, 2013 post titled “Electric cars to accelerate from 1 to 25 in 5 years.

31 May 2013 | Japan
Why Toyota is clear leader in electric vehicles: What next?
Toyota is the largest electric vehicle (EV) manufacturer by value; its EV gross sales product (GSP) being over 40% of the total global EV market (hybrid and pure electric) of $65 billion in 2013, with over 4,400 manufacturers sharing the rest.
Most of those make e-bikes, of course. Toyota is many times the size of its nearest competition in EVs by value of sales. Yet EVs are not yet responsible for most of Toyota’s gross sales product overall – or anywhere near. Its EV success is partly because it is the global leader in heavy industrial pure electric and hybrid EVs. To be precise, it is the leader in material handling EVs such as forklifts, with around $6 billion in sales there alone, whereas heavy EVs for earthmoving, mining and agriculture are in their infancy.
It is the global leader in hybrid cars, a market many times larger than that for pure electric cars, and it is in the top ten in electric buses worldwide, another of the largest market sectors with one of the largest growth rates. The hybrid car figures are particularly impressive:
• Seventeen percent of all cars sold in Japan in 2012 were hybrids, with 75% of those made by Toyota and its luxury car division.
• Toyota Motor Corp has sold more than 5 million gasoline-electric hybrid vehicles to the end of March 2013, since they first went on sale in 1997, the automaker said earlier this month.
• Its Prius series accounted for about 70 percent of that, making it the most popular hybrid model in the automotive industry.
• Globally, Toyota sold 1.2 million hybrid vehicles in 2012, the first time it sold more than 1 million hybrids in a single year.
Unprecedented depth and breadth of research
Toyota’s research into batteries, motors and other key components of EVs is unprecedented and in many cases it feeds subsidiaries making these components. The company efficiently cross-fertilises new EV technology between divisions unlike many competitors that enter other EV sectors then compartmentalise the divisions involved.
Challenges
Toyota is not without its challenges. Material handling will not be one of the fastest growing sectors as recovery from the drop in recession becomes complete. Hybrid cars will eventually give way to pure electric cars, where Toyota is largely playing a waiting game, invested in Tesla and correctly perceiving that they are not quite ready for mainstream prime time. The largest demand for electric buses will be in the rigged Chinese market for the coming decade and, there, Toyota will not be permitted to overtake national champion Yutong. The imminently huge military EV sector has no significant participation by Toyota and it is weak in the burgeoning light industrial/commercial EV sector.

Solar Impulse to fly across America – day and night without fuel

Solar Impulse, the Swiss solar powered airplane, plans to depart from San Francisco today with Bertrand Piccard in the single seater cockpit, to complete the first leg of its coast-to-coast flights across the USA. It is the first time that a solar airplane capable of flying day and night without fuel, will attempt to fly across America. This journey is also the occasion to launch an initiative called “Clean Generation” to gather worldwide support for the adoption of clean technologies.

Flying Coast to Coast across the United States has always been a mythical endeavor in aviation history. Achieving this in a solar airplane capable of flying day and night without fuel, shows the enormous potential of clean technologies in terms of energy efficiency and renewable energy use. With this adventure, Solar Impulse wants to inspire and motivate as many people as possible to embrace the pioneering spirit that allowed this revolutionary solar-powered airplane to become a reality.

This is why thousands of people, amongst which James Cameron, Buzz Aldrin, Richard Branson, Elie Wiesel and Erik Lindbergh, are supporting the “Clean Generation” Initiative to encourage governments, businesses and decision-makers to push for the adoption of clean technologies and sustainable energy solutions. Concretely, the names of all those who will join this movement of pioneers will be carried in the cockpit of the airplane as virtual passengers. At every stopover city along the way, more and more names will be added onto the list.

About the first leg San Francisco – Phoenix

Phoenix Sky Harbor International Airport will be Solar Impulse’s first stop. The airplane is expected to take off today at 6:00 am (PDT) from Moffett Field, NASA Ames Research Center in Mountain View (CA), and land the following day around 1 am (MST) in Phoenix (AZ). Estimated flight duration is 19 hours.

Bertrand Piccard and André Borschberg will alternately pilot the solar airplane to complete the challenge of flying without a drop of fuel across the USA from the West to the East Coasts. The first leg of the flight leading to Phoenix Sky Harbor International Airport (AZ) will be completed by Bertrand Piccard. André Borschberg will fly for the last leg culminating in New York at JF Kennedy Airport.

Diesel engine exhaust contains carbon dioxide, carbon monoxide and other potentially toxic gases. It also contains fine particulate matter, some in the form of soot, which can build up in a person’s lungs. People who live in high-traffic or high-smog areas or who work around diesel engines and diesel fumes can develop health problems, some of which can be lethal.

Diesel Exhaust Fumes Linked to Cancer and Other Serious Health Effects

With the recent confirmation by the World Health Organization (WHO) that diesel engine fumes can cause cancer in humans, millions worldwide will now know the serious health risks in breathing in diesel gas fumes. Diesel exhaust fumes are ‘major cancer risk’ and as deadly as asbestos and mustard gas, says World Health Organization.

People at Risk

Children and the elderly are the most at risk of health problems associated with exposure to diesel fumes. People with cardiovascular diseases, emphysema and asthma are also more vulnerable than otherwise healthy people to the effects of diesel exhaust.

Effects of Acute Exposure

Acute exposure is short-term exposure to diesel exhaust. This short-term exposure can cause eye, nose and throat irritation and can cause the victim to feel light-headed. Breathing diesel fumes can cause those with asthma to suffer an attack and may interfere with the breathing of emphysema sufferers. If a person is subjected to repeated acute exposure, his health problems may become chronic and worsen over time.

Effects of Chronic Exposure

Chronic exposure can either be repeated short exposures or the result of being around diesel fumes for long periods. The fine particles in diesel exhaust have substances such as formaldehyde attached to them. When breathed by a person for long periods of time, these particles and other gases and substances in diesel exhaust can damage the immune system, interfere with hormone production and cause cancer.

The Center for Disease Control and Prevention (CDC) recommendation: avoid exposure to diesel exhaust.

Darko Kapelina quotes hockey great Wayne Gretzky who said that to win, “you have to skate to where the puck is going, not to where it is now”.  In 2012 there were an estimated 25,000 electric cars sold worldwide, representing less than 1% of all car sales.  Projections are that by 2018 the number of electric cars sold including 100% electric and hybrid will grow to 10,000,000 or 25% of all car sales! Kapelina is interested in clean sailing ideas and systems.

Darko Kapelina believes that truly clean sailing is within our grasp. There are far too many compelling reasons answering the why? less dependency fossil fuel, no oil in the bilge, no noise, no pollution, no gas, no fumes, an electric motor is silent, clean electricity is far more available than marine fuel stations, no more fear of onboard fuel fire, no more fear of carbon monoxide poising, which leads to the what and how? Darko Kapelina is interested in electric sailing ideas and proven systems.

Darko Kapelina states that aircraft design will never be the same again after the pressure to save the planet, reduce local noise, air and land pollution, reduce dependency on oil and large areas of land for operations and to modernize industry or see it collapse. Belatedly, leaded fuel is being banned for aviation and considerable financial support is now available for the creation of new types of electric aircraft.

The next generation of electric aircraft is being designed from the ground up rather than shoehorned into existing airframes! According to Darko Kapelina the same will occur in the sailboat manufacturing industry.
