Brewers have toyed with portable beer concentrates before—by evaporating the water from finished brews. But along with the water go the hops, which impart flavor. Pat Tatera of Pat's Backcountry Beverages developed a process to brew concentrate instead of beer. With seltzer—the company also sells a $30 carbonator bottle—campers can turn one pouch of it into a pint of full-flavored pale ale. Tatera's brewing process starts like that of any ale.

Skills. How to Make Inexpensive DIY Home-Built Solar Panels with Damaged Solar Cells from Ebay. Mike Davis is an astronomer.
To practice his hobby away from the light pollution of cities, he bought some land in a remote part of Arizona. But there was a problem: No electricity. But he's a resourceful fellow. He built some solar panels using inexpensive blemished and damaged solar cells from eBay! Read on for more photos and some technical details to give you an idea of how he did it. I bought a couple of bricks of 3 by 6 mono-crystalline solar cells.
A solar panel is really just a shallow box. Next I cut two pieces of masonite pegboard to fit inside the wells. I laid out the cells on that grid pattern upside-down so I could solder them together. I used a low-wattage soldering iron and fine rosen-core solder. Here's what the solar panel looks like from the front. Here I am testing first half panel outside in the sun. I drilled a hole in the back of the panel near the top for the wires to exit. [...] Here is the finished product, producing 18.8 volts and 3.05 amps in the sun.

Posted by Dave Llorens on September 8th, 2010 It Sounds Crazy, But It’s True Here at One Block Off the Grid, we’re constantly striving to demonstrate not only how much money solar can save, but also make for households, so we decided to conduct a little experiment: let’s say you, the homeowner, had $20,000 to invest today. What would happen if you decided to put panels on your roof instead of putting it in the bank? Now bear in mind that, rates of return are different in different areas, so we looked at exactly how this would play out in three different markets: San Francisco, Long Island, and New Jersey. Our conclusion: investing in solar trounced the bank in every city tested. Method: to approximate the rates of return from going solar, we had you, our homeowner, invest your electricity savings in a bank account with 4 percent interest.

Simple Ideas That Are Borderline Genius (35 Pics) 7 Design Principles, Inspired By Zen Wisdom. One of the best-known photographs of the late Steve Jobs pictures him sitting in the middle of the living room of his Los Altos house, circa 1982.
There isn’t much in the room, save an audio system and a Tiffany lamp. Jobs is sipping tea, sitting yoga-style on a mat, with but a few books around him. The picture speaks volumes about the less-is-more motive behind every Apple product designed under his command. As Warren Berger wrote on Co.Design, Jobs’s love for elegantly simple, intuitive design is widely attributed to his appreciation of Zen philosophy (Jobs was a practicing Buddhist). But while many people might be familiar with Zen as a broad concept, far fewer are knowledgeable of the key aesthetic principles that collectively comprise the “Zen of design.” To understand the Zen principles, a good starting point is shibumi. James Michener referred to shibumi in his 1968 novel Iberia, writing that it can’t be translated and has no explanation.
