How Viable Are Hydrogen Fuel Cells in Construction Equipment?
Hydrogen fuel cell (HFC) technology and its potential application in construction equipment is being increasingly talked about in certain circles, but there are questions surrounding how cost effective it can be in real-world applications. To date, it’s mostly being used in lift trucks, offering lower operating costs, reduced emissions, improved reliability, and much faster refueling compared with battery charging/swapping.
The concept is fairly simple; HFCs essentially combine hydrogen and oxygen to produce electricity, which runs a motor. The only byproducts are heat and water.
The fuel cells are compact too, taking up less space than batteries, giving equipment manufacturers more room to play with in machine designs. Unlike traditional lead-acid batteries, hydrogen fuel cells have no power degradation, and refueling takes about three minutes, much like an internal combustion engine.
So what’s the downside? Expense, for one. The cost is higher than more time-tested technologies, but experts report that will come down over time as adoption increases. Another positive is that there is no grid dependency and solar power can be harnessed to make hydrogen on site so, in concept, it could be a sustainable technology.
Some companies are working diligently to make HFC a reality on construction sites. Cummins, for example, recently acquired Hydrogenics for its fuel cell production capabilities. Their technology is being tested on trucks and rail and will be applicable to industrial use at some time in the future, Nendick says.
“Hydrogen as a power solution is very exciting and there is certainly a future for the development of hydrogen fuels cells in equipment in the future,” he states.
“Cummins is investing in long-term hydrogen capability. Following the Hydrogenics acquisition we have also developed relationships with Loop Energy and NPROXX, looking at hydrogen storage and transportation as well as production.”
There are challenges with this technology, of course. Haberland at MAN notes that hydrogen is very difficult to store and distribute because its atomic structure is very volatile. “Over time it dissipates,” he explains. “It requires a very complex and expensive storage infrastructure on the vehicle itself.”
He also adds, “It needs to be stated that this technology is only beneficial if you take the electricity to produce the hydrogen out of renewable sources. If you use a fossil fuel to do it, then it’s not a green technology at all.”
JCB recently announced that it has developed what it claims to be the construction industry’s first ever working prototype of a hydrogen-powered excavator.
The 20 tonne 220X excavator powered by a hydrogen fuel cell has been undergoing testing at JCB’s quarry proving grounds for more than 12 months.
JCB Chairman Lord Bamford said, “The development of the first hydrogen fuelled excavator is very exciting as we strive towards a zero carbon world.
“In the coming months, JCB will continue to develop and refine this technology with advanced testing of our prototype machine and we will continue to be at the forefront of technologies designed to build a zero carbon future.”

Things to Consider When Planning to Build a Sunroom or Conservatory
We may love our homes, but there are times when virtually everyone feels a bit boxed in. Perhaps we've outgrown our home, or maybe it just feels a bit dark and claustrophobic. For whatever reason, there are times when it would just feel good to bring extra light and airiness to our homes. While the popularity of sunrooms has waxed and waned over the years, most people think of a sun room as an aluminum structure that lets all of the heat out in the winter and turns into an oven in the summer.
New Materials for Better Sunrooms
Well, times have changed, and so have the materials used to build sunrooms. These days, homeowners are increasingly choosing sunrooms that use vinyl-wood composite for the framing and high-quality windows from the floor to the ceiling. The result? Well, there aren't any unsightly screws or fasteners on the walls or around the windows; instead, lovely trim and moldings provide the finishing touches. Plus, the energy efficiency is unbeatable. A typical aluminum-framed sun room is between ten and fifty percent below EPA requirements for habitable structures. In contrast, a special wood-composite sunroom average twenty-five to forty percent better than EPA codes. This means that, for example, if you live in a state like Texas, your sunroom is usable year-round and won't cause your energy bills to soar. Plus, the cost of building a sunroom out of these new materials is about that of an aluminum sunroom - and decidedly less than an all-out remodel.
Conservatories: A Step Beyond
If you think you'd enjoy the comfort and relaxation of a sunroom, conservatories put your home into a class all by itself. Sometimes called a solarium, a conservatory often becomes the most used room in a home. Mahogany conservatories are gorgeous, and typically are available in a variety of roof styles, including Windsor, Georgian, and Victorian.
Dressing Up Your Patio
Many homeowners have nice patios, but simply don't use them. Often, especially in places like TX, it's just too darned hot to have the sun beating down on you. If that's the case, then it's easy to dress up your patio with a patio enclosure, a patio cover, or an arbor. Enclosing or covering your patio gives you that much more living space and enables you to truly enjoy your backyard.
Finding the Right Company
Whether you want a sunroom, a solarium, or a patio enclosure, it's important to find a company you can rely on. Make sure that all materials and labor are backed by a 100% lifetime transferable warranty, which will be attractive to buyers if you ever sell your home. Moreover, the company you choose should provide you with a buyer's guide, a contractor's evaluation sheet, and design options before you buy. The best companies even offer a 3D architectural rendering so that you will know what your room will look like.
A sunroom or conservatory is a wonderful way to breathe new life into your home. So let the sun shine in!

What is the Difference Between Commercial and Residential Wallpaper?
Wallpaper has been around for hundreds of years, and yet people claim that there has been very little advancement in wallpaper. At the surface it might seem like a remark that seems true, but the truth is far from it, wallpaper has evolved from the really old looking red and white stripe paper, to a work of art that can adorn your home, or your work place. There are more or less no limits to the colours, variations and styles you can choose from, the best part is, contrary to popular belief wallpaper has evolved and changed as time has gone by, and they are no longer just another thing you put on your walls.
Just like art and fashion has evolved, so have the various styles of wallpaper, earlier wallpaper was made to resemble the various tapestry styles, as fashion style and taste of people evolved, the wall papers became more and more diverse. Just like clothing, technology and so many other things today, wallpaper has now come to reflect the taste and moods of a home owner. With the numerous advances in technology, the method of printing wallpaper too has advanced, earlier massive offset printers, or block printers were used to manufacture wallpaper, where as today more and more people are turning to digitally printed wallpaper for their homes.
Today wallpaper is classified based on the commercial application, and is divided into two categories commercial and home use wallpaper
Commercial Wallpaper
Commercial wallpaper is usually printed on thicker, and more resistant paper. Since commercial wallpaper (as the name suggests) is used in retail outlets, hotels, discos etc. The wallpaper has certain health and safety specifications that it must meet like being fire resistant etc. Apart from the health and safety requirements, there are additional requirements like being easy to clean, dust and dirt resistant etc. What has made commercial wallpaper making an entirely different section, is that more often than not commercial wallpaper involves customization like having a company logo printed or having custom designs, this is where having a digitally printed wallpaper comes in handy, as the imagery that is produced using digitally printed wallpaper is far superior when compared to wallpaper printed using traditional methods.
Wallpaper for home use
The earliest and oldest application of wallpaper is for home use, wallpaper for home use is by no way inferior to commercial wallpaper, as it too has to meet strict quality control guidelines, however the added advantage that wallpaper for home use has is that, it is easier to apply when compared to commercial wallpaper, and in addition you can have multiple wallpaper in the same home (compare this to commercial establishments where the wallpaper is uniform throughout). Just like commercial wallpaper, digitally printed wallpaper is available for home users also, the biggest benefactors of digitally printed wall paper have been home owners, who can now either get custom wallpaper with a particular design built, or can choose to adorn their home walls with some of the greatest works of art ever made. The choices that wallpaper today has bought to home owners is just mind boggling, and all it takes to get customized wallpaper made is a photograph or image of your design.

How to Create Oriental Decor in Your Home?
To counteract the frenetic pace of today's hectic lifestyle, you probably want your home to be your sanctuary. And, when it comes to decorating your home, Asian decor is unique in its ability to convey that sense of peacefulness and harmony that is all too often missing from other elements of life.
One of the wonderful things about Oriental decor is that it's extremely flexible. You can add soothing Asian touches throughout your home, or go all out and transform your living space into a serene Asian paradise. Either way, here are some ideas to inspire you:
Asian Lamps
Asian lamps can add a decorative touch and infuse warm light in your living room or bedroom. Saa paper lamps are typically square, and are constructed from natural materials like bamboo, teak, or rattan, with handmade and hand-painted saa paper covering the frame. While some Asian lamps are painted with a decidedly Asian theme, others complement any style of home decor. Available in a variety of colors and designs, these lamps bring both artistry and harmony to a room.
For the Table
Asian-inspired table settings stand out for their elegance and simplicity. Bamboo placemats can be used every day or paired with silk table runners to bring more formality to mealtime. Bamboo skin candleholders and tea lights add to the ambiance created by good food and great friends.
Accents for the Home
Whether you'd like to recover throw pillows on your couch or want to accent infuse your bedroom with an Asian influence, you can't go wrong with cushion covers. Handmade using natural fibers like Thai silk, wool, and cotton, you can easily slip them over your existing pillows or slip a pillow form into them.
Another way to bring contemporary Asian decor into your home is through the use of silk photo frames. Thai silk gives your treasured photographs an elegant touch, while the fabric patterns easily coordinate with modern home decor. Similarly, silk jewelry boxes are like art, in that they add a touch of elegance to your decor while allowing your precious jewelry to shine.
Silk shawls and silk scarves can also bring color and texture to your home decor. Hand-woven in both rough and smooth textures, silk shawls and scarves come in virtually every color and finish imaginable. Use them to drape over nightstands, as runners across dressers, and over lamps (not too close to the bulbs, though!) to add elegance and a touch of romance.
Beyond the Home
While you're shopping for silk scarves, you may want to select silk handbags for your wardrobe. Elegant silk evening bags are the perfect accessory for formalwear, while totes and backpacks are beautiful and functional for everyday use.
Shopping for Asian Decor
In times past, shopping for Asian decor meant traveling to exotic locales or paying high-end designers to discover exquisite pieces. Thanks to the Internet, though, you can shop for and buy Asian decor directly from Asia-based wholesalers who work on behalf of an artisan who crafts the pieces by hand. In other words, creating a home filled with tranquility and harmony can be achieved with a few clicks of your mouse.
