This window can help power a skyscraper: Imagine if windows could be designed to collect the electricity used to power a home or a skyscraper. The technology that could make that a reality might be closer than you think. In fact, it could be ready by next year, said John Conklin, the president and CEO of SolarWindow Technologies Inc.

This is something that would revolutionize clean energy for large commercial buildings, which are the company's primary target market, Conklin told National Observer. “I truly believe it’s one of the most disruptive and perhaps one of the single greatest breakthroughs in clean energy ever,” he said.

Maintaining the window's transparency a challenge:

Designing the technology has meant working out solutions. The biggest has been ensuring the windows remain transparent while still generating enough electricity. The windows require a special coating that turns ordinary glass into a conductor that transforms energy into electricity that feeds directly into the building's power system.

During Maryland-based SolarWindow’s early years in 2009 and 2010, a number of individuals told the firm’s team that it would be impossible for them to create a transparent photo-voltaic technology. “We defied that,” Conklin said.

The U.S. Department of Energy's National Renewable Energy Lab (NREL) has been working with SolarWindow on the technology and the two partners are now focused on ensuring that the coatings can work on larger areas of glass. “Challenges are always there. Nothing is easy in this area,” said Maikel van Hest, a senior scientist in the Thin Film and Processing Group within the National Center for Photovoltaics at NREL.

Right now, SolarWindow estimates that its technology can generate 50 times more energy than rooftop solar panels would in a 50-storey building. Using all four sides of the building, in a 50-story glass skyscraper, this would consist of six acres of glass - enough to provide far more than the one megawatt of power that would come from a rooftop solar array, Conklin said. This is much more space than what's available on a skyscraper’s roof. “The name of the game is real estate,” he said.

Overall, the refurbished windows could offset the equivalent of the emissions from vehicles traveling nearly 3.5 million kilometres by reducing energy demands in a 50-storey building, Conklin estimated. But he also noted that skyscrapers use huge amounts of energy and that the new solar windows would only cover somewhere between 30 to 50 per cent of total power consumption. “This is a tremendous opportunity for the environment, a tremendous opportunity for renewable energy and especially for tall towers and skyscrapers to finally get some renewable energy.”

Home owners might one day find the same technology in their houses. The more glass a home has, the more power it would be able to generate. But for now, SolarWindow plans to pursue the more lucrative commercial market first, where Conklin believes there are significant business opportunities. He said the commercial market is huge, estimated to be a $100-billion global market for flat glass and fabricated windows. Out of that, SolarWindow is targeting some five million commercial buildings in the U.S.

Here's how the SolarWindow works:

SolarWindow’s organic photovoltaic technology uses ordinary window glass and then applies different layers of coatings made of carbon, nitrogen, hydrogen and oxygen are applied. Transparent conductors form two layers. Between the two is a third layer, which absorbs light. When it comes in contact with the chemical coating, the solar energy is transformed into electrons. The movement of the electrons produces the electricity on the surface of the glass. The conductors on each side transport the electricity to ultra-thin wires inside the window frame. Those in turn feed the energy into the building’s electrical systems.

Conklin, an industrial consultant who has studied chemical engineering, helped develop similar surfacing coating techniques used in the fabrication of the United States Stealth Battleship prototype while at Excel Precision Inc. He is also the founder and vice president of National Solar Systems, LLC, a New York-based renewable and alternative energy design and installation firm.

SolarWindow is not alone in trying to develop solar-powered windows. Some companies, for example, have small strips over the glass that absorb the light. But these strips wind up creating a pattern that’s almost like having window blinds, according to van Hest.

But while no company has yet managed to commercialize a truly see-through window, SolarWindow says their windows will be like any other windows and will come in architecturally desirable tints and shades. “That’s the nice thing about SolarWindow’s photovoltaic, the way they’re doing it. It’s not obstructing your view from the outside world,” said van Hest from NREL, the U.S. government lab.

But he added that with every step comes a new hurdle, such as choice of materials or how those materials are applied. “Yeah there’s definitely some hurdles, but we have pathways on taking those hurdles and taking it to the next step, which would be commercialization.”

Paula McGarrigle, managing director of SOLAS Energy Consulting Inc. in Calgary, said SolarWindow’s concept is great. “I love the idea of using the horizontal spaces on windows to generate electricity.” According to McGarrigle, the economics of the technology will depend on a number of variables such as the energy load of the building, how much surface area is available on a building and the power prices of a jurisdiction.

Conklin said the cost of SolarWindow’s technology would be “low,” and calls it a “very small add-on price point to an existing window,” which would be paid back in less than one year for a skyscraper.

Solar power from all four sides of a building:

In order to get their technology to market, SolarWindow needs to raise additional capital. To date, the company has relied on private placements from investors. The firm also wants to form partnerships with glass and window fabrication companies as well as chemical companies.

Conklin, who describes himself as risk-averse, said it’s not his intention to start the company up in a $45-$50-million production facility when glass manufacturers already exist. “We’ve already demonstrated our process can be seamlessly integrated into a glass manufacturer or window fabricator and coated right at their facility.”

Partnerships with the right chemical firms are important because the technology employs various chemicals applied to glass to generate the electricity. Such partnerships will enable SolarWindow to hold down its operating expenses and capital costs while achieving an affordable price for the windows.

The technology is able to generate power on all four sides of a building, not just on the south-facing side in the Northern hemisphere. Conklin said the coatings can create electricity under shaded, diffused and low-light conditions.

That ability to use the same glass on all four sides of a building will make the technology attractive to architects, developers and designers who are looking to generate renewable energy but still maintain the aesthetic beauty of a building, Conklin added.

When Clients Ask For Discounts

How many of your window cleaning customers ask for discounts? Here's Jurgen Appelo talking about affordability & vendors. Why are clients entitled to ask this question?

When Clients Ask for Discounts, Ask Them ... Why? (By JURGEN APPELO, Writer, Speaker, Entrepreneur, CEO of Happy Melly). I bought several new vests recently. One was from G-Star, another from Banana Republic. They were not cheap, but not unreasonably expensive, either. I paid the price the shop asked from me. What I did not do was haggle over the price with the vendor.

As a professional public speaker, I have fees, as well, which are listed publicly on my website. I am not cheap, but I'm also not unreasonably expensive. And I always try to be transparent in my pricing. That means that I prefer not to waste my time on price negotiations. Sometimes, though, potential clients contact me and say, "We'd love to hire you as a speaker. But can we get a discount?" I've found a great way to deal with these discount requests: I ask my customers, "Why?"

My usual reply also includes something alone the lines of, "Is there a specific reason you believe you are entitled to a discount?" Without my directly saying yes or no, I've thus bounced the question back to the customer(s), forcing them to consider what they're asking and to give them a chance to point out something that could be of value to me.

Sometimes, clients tell me they cannot afford my standard fee, so they're hoping to get me at half my regular price. Sometimes, they even ask me to do my work for free. "It will be a great opportunity to present your book!" they say. But this always baffles me. I have never considered asking G-Star or Banana Republic to sell me a vest at half the price, or to just give it away for free: "It will be a great opportunity to show off your t-shirts!"

If I found such vendors too expensive, I wouldn't have shopped with them at all. Instead, I would have checked out H&M or Zara. So, faced with the discount question, my next move is to tell such clients that I will happily refer them to other speakers.

Sometimes, clients are so big or famous and consider themselves so important, that the magnitude of their arrogance itself seems to qualify them for a discount. They say (or at least obviously think): "You will be able to add our name to your list of clients!"

Fortunately, my own arrogance is quite flexible and, when needed, strong enough to match that of the client: "Indeed, I will! And you can tell everyone that I visited your company, after you paid what everyone else pays!"

Sometimes, clients just love haggling, assuming there are always margins that can be squeezed. My problem with this attitude is that such clients assume that I am intentionally overpaid and that, with some negotiation, it should be possible to talk the fee down to the "proper" price. In other words, they assume I have a lack of integrity (i.e., I'm asking too much.)

Another possibility is that they assume that I so desperately need the sale that I'm willing to be underpaid, which (to me) seems like a lack of integrity on the side of the client. They might say, "You probably have a special price for friends," to which I might reply, "I have many friends and my fee is what they pay. I assume you want me to treat all my friends equally and fairly?"

And, last but not least, after I ask them, "Why?", the clients sometimes tell me, "Oh, never mind. We were just wondering." Then they proceed to pay my regular fee. I have no objections to that at all.

Notice that I don't say "no" to people who ask me for a discount. I merely ask them "Why?" because it's quite possible that they have a very good reason! It all comes down to customizing the value exchange.

It happens that some clients, for example, offer me a speaking opportunity right before or after an event that I have already booked in the same city. Having two or three events back-to-back in the same area saves me a lot of travel time and travel expenses. Obviously, that would be worth a #NoTravel discount.

It also happens sometimes that a client invites me for the third or fourth time. Obviously, I value repeat customers who develop a preference for a long-term relationship with me, which is worth a #RepeatBusiness discount.

There are some clients who order large quantities of my books. Despite the fact that authors like me earn very little per book in terms of royalties, I still appreciate that my message is distributed into the hands of many people. And so that scenario is worth a #BookOrders discount.

There is also value for me in being able to pick a topic of my own choosing and to experiment with unconventional ideas and formats in my presentations. Customers who give me the freedom to do whatever I want are entitled to an #Experimentation discount.

And then there is my much-beloved discount to discourage bureaucracy, which reduces my fee when clients don't ask me for contracts, tax records, travel receipts, bank statements, procurement forms, visa forms, birth certificates, etc. This #NoBureaucracy discount is basically a reward for good behavior.

There is something else important to realize here: All the good reasons for offering discounts that I listed above can (and should) be translated to clear, unambiguous pricing rules. After all, if you want to be seen as fair, transparent and honest, you have no other option than to apply the same rules (and discounts) to all your clients. And, yes, the rules are additive, and thus the discounts, cumulative.

When I introduce a new discount rule (sometimes because a client inspired me with a new good reason), I also decide on the start date of the new rule, as if I've just passed a new law. All customers invoiced on or after that date will be entitled to the same discount. They don't even have to remind me.

Today, I sent one of my clients an invoice with a #NoTravel discount. The client didn't ask for it. He didn't even know about it. But he earned it because he committed to adapt his own schedule to an existing conference I was attending so that I didn't have to make an extra trip.

It makes me feel good to offer a surprise discount to those who don't request one for no good reason. To make myself feel even better, I plan to be wearing one of my lovely new not-too-expensive vests.

How I Sell Without Using Discounts: People discount because they get desperate and they want to make some quick money. You’re training your customers not to purchase new things from you when they first come out, but to wait for a discount.  

It's Just Too Dirty - Political Window Cleaning

Angry protesters say they are trying to highlight the need for transparency over the trade deal.

'It's just too dirty' - TPP protesters wash minister's windows: Anti-TPP protesters have taken their plea to see the details of the trans Pacific trade deal to a whole new level, washing the windows of the Trade Minister's office to highlight the need for transparency. About a dozen protesters kitted out in yellow and orange jackets and wielding window mops gathered outside Tim Groser's New Lynn office in Auckland and took to the front window with buckets of soapy water.

"It's just too dirty," a male protester is heard to say in a video captured by ONE News. But was he talking about the window, the trans-Pacific Partnership Agreement - or both? "We want more transparency with the TPPA. So we're trying to highlight the need for transparency," a female protester explained, as she reached to clean the top of the window.

All the while, Tim Groser's picture on the window smiled out at the unhappy protesters. "Hon Tim Groser National MP", the accompanying sign for the National List MP explains. A woman waved a banner at passing motorists which showed "TPPA" written in a magnifying glass and demanded "Show us ya text".

Trade ministers failed at the start of the month to reach agreement on the proposed free trade agreement between 12 Pacific rim nations including the US and New Zealand which has been under secret negotiation for several years. Opponents of the deal say if New Zealand signs we risk damage to our economy, environment, health and ability to shape our own future, and the details of the agreement should be made public now.
