WIND POWER WITHOUT THE BLADES

Noise from wind turbine blades, inadvertent bat and bird kills and even the way wind turbines look have made installing them anything but a breeze. New York design firm Atelier DNA has an alternative concept that ditches blades in favor of stalks. Resembling thin cattails, the Windstalks generate electricity when the wind sets them waving. The designers came up with the idea for the planned city Masdar, a 2.3-square-mile, automobile-free area being built outside of Abu Dhabi. Atelier DNA’s “Windstalk” project came in second in the  Land Art Generator  competition a contest sponsored by Madsar to identify the best work of art that generates renewable energy from a pool of international submissions. The proposed design calls for 1,203 “stalks,” each 180-feet high with concrete bases that are between about 33- and 66-feet wide. The carbon-fiber stalks, reinforced with resin, are about a foot wide at the base tapering to about 2 inches at the top. Each stalk will contain alterna...

Why Users Fill Out Forms Faster with Top Aligned Labels

mag­ine a user who is really excited about your prod­uct or ser­vice. They’re ready to sign up, so they go to your form page and start fill­ing out their infor­ma­tion. The way you align your labels with your form fields can affect how easy it is for users to fill out the form. Do you want to give users a quick, easy and pain­less expe­ri­ence or do you want to give them a has­sle? If you want to make their expe­ri­ence quick, easy and pain­less, con­sider using  top aligned labels for your form fields . Top aligned labels are faster and eas­ier to fill out than left or right aligned labels. This is because top aligned labels  require half as many visual fix­a­tions than left or right aligned labels.  Top aligned labels also allow users to move down the form in one visual direc­tion, instead of two visual direc­tions with left and right aligned labels. This makes fill­ing out forms quicker and easier. The only draw­back with top aligned labels is that they...

Breakthrough: sensors that can convert thoughts into speech

A mind reading machine has edged closer to reality after scientists found a way of converting thoughts into words. Researchers were able to render brain signals into speech for the first time, relying on sensors attached to the brain surface. The breakthrough, which is up to 90 percent accurate, will be a boon for paralysed patients who cannot speak and could help read anyone’s thoughts ultimately, reports the Telegraph. “We were beside ourselves with excitement when it started working,” said Prof Bradley Greger, bioengineer at the Utah University who led the project. “It was just one of the moments when everything came together. “We have been able to decode spoken words using only signals from the brain with a device that has promise for long-term use in paralysed patients who cannot speak. I would call it brain reading and we hope that in two or three years it will be available for use for paralysed patients.” The breakthrough came when the team attached two button-sized grids of 1...

SCIENTISTS DEVELOP AFFORDABLE SOLAR PANELS THAT WORK IN THE DARK

It's about damn time, don't you think? Scientists at Lawrence Berkeley National Laboratory announced Wednesday that they have been able to confirm a new high-efficiency solar cell design that utilizes nearly the entire solar spectrum. Translation: They figured out a way to make solar panels generate electricity in the dark. CleanTechnica says , In earlier trials, the researchers used different alloys that achieved full spectrum responses but involved very high production costs. The advantage of gallium arsenide nitride is that it is very similar to a conventional semiconductor, gallium arsenide, and it can be produced with a commonly used fabrication method involving chemical vapor deposition. The Lawrence Berkeley breakthrough represents just one path to increasing the efficiency and lowering the cost of solar cells. Over at Ohio State University, a full spectrum solar cell is also under development, and Stanford is pursuing a new technology that cuts around the problem of ...

The 8 Buyer Personas (and How to Sell to Them)

Warp 9 Walt is a change agent with a strong sense of urgency. He's just one of the eight buyer personas... A while ago at a conference I had dinner with two people. The first, (we’ll call her Janine) I had known since we worked together six years earlier. The second person (Ed), Janine and I had just met. Janine described a sales challenge she was facing. She’d been working with two prospects at two different organizations, one for over a year and one for almost two. The typical sales cycle is 6 to 9 months, and these were both well beyond. She felt she was nearing a sale with both, but for all she knew, “nearing” might mean a year or two to go. This is a fairly common sales challenge: The sale looks good, but it’s taking forever. Janine happened to be facing two at the same time. As we talked, I asked Janine a number of questions. She believed that in both situations the buyers: were the decision makers, had the financial ability to buy, had a need, saw Janine’s company as d...
