How I built an electricity producing Solar Panel. Several years ago I bought some remote property in Arizona.

How I built an electricity producing Solar Panel

I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city slicker yuppies (you know the kind, the ones that like to blab loudly on their cell phone while they work on some business administration degree in a cyber cafe somewhere in Trendyland.) and their light pollution, I found a great piece of remote property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. I built a wind turbine to provide some power on the remote property. Here is a video of the solar panel set up and in use on my remote, off-grid property.

Let me state up front that I probably won't be able to help you out much if you decide to build your own solar panel(s). So what is a solar panel anyway? After a while, I came to some conclusions: Pranav Mistry: The thrilling potential of SixthSense technology.

Productivity Future Vision. How It Would Work: Creating a Quantum Computer. Silicon semiconductors have taken us a dazzling distance along the computing road. But even if they continue unabated to get faster and more powerful (and it's growing more difficult to make that happen) there's a limit to what classical computing can do. The next real game-change in computing is quantum--tapping the quantum mechanical properties of materials to process information in ways that will make today's biggest and baddest super computers look like pocket calculators.

And for the first time scientists, at places like IBM, are moving beyond just theorizing about them to actually envisioning how a finished quantum computer would work. In labs across the globe, the first building blocks of the first quantum computers are slowly becoming real. That's huge considering a working quantum computer would be the kind of thing that truly moves the ground beneath our feet. But first they have to build one. Like their classical cousins, quantum computers rely on units of information. Marco Tempest: A magical tale (with augmented reality) The IT Pro - The Nerve Center of the Private Cloud.

Scientists Develop Affordable Solar Panels That Work In The Dark

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. In the meantime, you could just turn any metal surface into solar panels with photovoltaic spray paint . [Photo: Norby /Flickr] Rules of Thumb: Ingenious Hand-Held Digital Tape Measure & Dornob. The history of measurement has come full circle, from body-based units to abstracted quantifiers … and now back again to the basics.

Rules of Thumb: Ingenious Hand-Held Digital Tape Measure & Dornob

From lengths and widths to volumes, this set of finger-mounted devices is designed to let the user measure anything, store that data, calculate results and more. Wooden sticks gave way to wood-and-metal rulers and measuring tapes, which in turn were replaced over time by higher-technology digital tools for fine-tuned measurements. Still, how often do you find yourself needing precision down to the very last millimeter or hundredth of an inch in daily life, as a designer or otherwise?

Unlike other precursors, this set of miniature measurers works at essentially any scale – put them both on one hand for small distances, two hands for medium ones or trade them between two different people for longer requirements.

Technology Entrepreneurship. Date: Wednesday, October 1, 2014 Summary: Every entrepreneur faces endless challenges along the way. These problems never have one right answer, and often they have never been solved before. The only way for an entrepreneur to succeed is to view each challenge as an opportunity for a creative solution. The best entrepreneurs seek out challenges.
