The microhydro plant

The microhydro plant
My little paradise has a stream that provides enough water flow and head to run a small turbine, to provide electricity to my home. While writing this, the microhydro plant is being implemented, and here are some photos of the process. Since I usually like to start at the end, the first thing I built is the controller: It is an implementation of Jan Portegijs' "Humming Bird", with some changes and adaptations. The largest cost of the plant, by far, is in the piping for the rather long penstock. When the purchase was made and the truck arrived, we unloaded the pipes at different places, to get them as close to the installation area as possible. A smaller number of pipes were stored closer to the turbine site. Only for the last part of the run, where the pressure exceeds 2 bar, I will use blue class 4 PVC pipe. To change from the low slope run of the white pipe to the much steeper run of the blue one, a change of direction is required. The flat area is where the forebay will be built. News!

Chocolate Chip Cookie Dough Peanut Butter Cups Soooooo… you know that episode of Sex and the City where Miranda has to dump dish soap on top of chocolate cake just so she will stop eating it?? Uh. Yeeeeeah. These are like… of that caliber. And that totally almost happened to me. I ate what felt like a million, then had a plate of 5-day old green bean fries from the fridge and called it lunch. I definitely recommend those. For lunch. Face? Inhale. Chocolate Chip Cookie Dough Peanut Butter Cups [cookie dough adapted from cookie dough dip] makes 24 cups 2 1/2 cups milk chocolate chips 1/2 cup unsalted butter 1/3 cup packed brown sugar 1 teaspoon vanilla extract 1/4 cup creamy peanut butter 3/4 cup powdered sugar 2 tablespoons all-purpose flour 1/4 teaspoon salt 1/2 cup mini chocolate chips In a small saucepan, heat butter until melted. Line a mini muffin with with liners. Remove muffin tin and cookie dough, then place 1 teaspoon of cookie dough (I somewhat rolled mine) into the chocolate cups. Sigh.

This 1,400-Foot Desert Citadel Would Be A Self-Sustaining City Of Tomorrow It may look like Immortan Joe's Citadel from Mad Max: Fury Road, but this abstract desert obelisk isn't a citadel of the post-apocalypse. It's a self-contained city—also called an arcology—that French firms Nicholas Laisné Associés and OXO Architects propose to build in the Saharan desert. Although it's just a concept right now, La Ville Tour Des Sables (translated: "The Sand Tower Town") would stand over 1,400 feet, if completed. Designed to resemble an outcropping of stone—or, at least, Bjarke Ingels' idea of what an outcropping of stone might look like—the arcology would contain everything needed for a self-sustaining city, including living quarters, agricultural units, factories, and more. According to OXO's official description of the project, the Sand Tower Town would have a total floor space of around 192 acres. Another big aspect of the design involves making maximum use of the desert's resources. [via io9] [Images: via OXO Architects]

& Overclock Your Reading Speed This is a guest post from Kim Roach of The Optimized Life. In today’s Information Age, reading is now a prerequisite for success in life. In fact, many presidents, including Kennedy, have required their staff to take speed reading lessons. Brian Tracy, a best-selling author, points out that just 1 hour per day of reading will make you an international expert in your chosen field within 7 years. If you’re looking to increase your learning rate while decreasing your effort, speed reading is a method you should consider studying. By simply learning how to process information at a more rapid rate, you’re not only going to be able to move through books more quickly, but you will also be able to comprehend and process more of what you have read. The Brain’s Power Speed reading actually began as part of military training to identify enemy war planes. What many people don’t realize is that the mind becomes bored when it’s not constantly stimulated. 1. 2. 3. 4. 5. 6.

How to Travel Full-Time for $17,000 a Year (or Less!) Wise Bread Picks For the last five years, I've been traveling the world full-time, and for less money than I've ever spent (and I'd wager less money than most people would spend) to live in one place. My worldly possessions fit into one bag (just larger than carry-on size) and a backpack containing my laptop and computer gear. In 2011 alone, I traversed 13 countries and over 45,360 miles. What if I told you it wasn't? Believe it. How to Keep Your Travel Costs Low Of course, I could travel for way more than $17,000/year. Here are a few of my secrets.

Virginia SUN | Citizens for Solar Take typing lessons, test your typing speed and practice typing for free! This is, a web application that will help you teach touch typing. Touch typing is typing without using the sense of sight to find the keys. A person possessing touch typing skills will know their location on the keyboard through muscle memory. It can improve any individual's typing speed and accuracy dramatically. This is a short tutorial that will explain how does this application work. You can use the left and right arrow keys to navigate through these slides. This tutorial is based on these few principles: No boring, repetitive exercises. Initially it starts generating words from a small subset of the most frequent letters of the alphabet. When you are typing these words, keybr measures time to type a key for every letter in that subset. Once you familiarize yourself with the current subset of letters, the algorithm expands it, including more and more letters to it. So at any time, you will by typing the letters you are least familiar with. This is the text board. ? ? ? ? ?

One can dream Once upon a time there were some very well-off folks in Vancouver who wanted big new homes. They called upon a builder by the name of Keystone Projects Ltd. and asked them to build the homes of their dreams. They asked for fancy kitchens and bathrooms and rooms for their pool tables and views to die for and a car lover's garage.
