Outdoor Fireplace by Haugen/Zohar Architects Haugen/Zohar Architects have designed an outdoor fireplace in Trondheim, Norway. Full description after the photos…. Photography by Grethe Fredriksen & Jason Havneraas Outdoor Fireplace by Haugen/Zohar Architects Together with the standard playground facilities we wished to combine an enclosed space for fire, storytelling and playing. Given a very limited budget, reusing leftover materials (from a nearby construction site) was a starting point that led the design to be based on short wooden pieces. Malcolm Gladwell's David And Goliath Jill Hutchison/Flickr Malcolm Gladwell seems to think attending an elite college or working for a famous company could kill your dreams. The popular author lays out his argument for being a big fish in a little pond in his latest book, "David and Goliath," a work that aims to overturn conventional notions about what makes for a disadvantage and who should be considered an underdog. Gladwell's basically against anyone attending a famous university just for the name, or really doing anything for the sake of prestige. To choose something elite is, more often than not, to choose being a little fish in a big pond, he says, since only a select few will shine among the best.

Home-made Hydraulic Ram Pump This information is provided as a service to those wanting to try to build their own hydraulic ram pump. The data from our experiences with one of these home-made hydraulic ram pumps is listed in Table 4 near the bottom of this document. The typical cost of fittings for an 1-1/4" pump is currently $120.00 (U.S.A.) regardless of whether galvanized or PVC fittings are used. Table 1. Image Key Off Grid Rainwater System Collects, Stores, and Purifies Water This rainwater collection system in the Canadian wilderness has provided a source of clean, potable water for this family of four’s off grid cabin for almost 20 years. The system is relatively simple and very low maintenance. Water is collected using a three hundred square foot piece of metal roofing, where it flows downhill into a gutter. It is passed through a layer of plastic mesh as it runs into the gutter to filter out any large debris, including the needles that drop onto the roof from surrounding trees. The water is then passed through a course filter as it leaves the gutter, filtering out even more of the larger debris. After leaving the course filter, the water is run down a pipe and through a fine filter where it is further cleansed before it enters the 2000-gallon storage tank.

Solar still Solar still built into a pit in the ground Solar still "Watercone" A solar still is a simple way of distilling water, using the heat of the Sun to drive evaporation from humid soil, and ambient air to cool a condenser film. Two basic types of solar stills are box and pit stills. Below sink - Ascot Hygiene Ltd Wijas Perfect below sink water heaters The Wijas water heater is the smallest on the UK market, measuring just 152 x 135 x 72mm. Click here to see how small. These non-vented heaters easily fit under a sink or in a cabinet to provide point of use water heating. They are extremely energy efficient too and you don't waste lots of running water waiting for the hot water to arrive. Puzzle: Fast Bit Counting Devise a fast algorithm for computing the number of 1-bits in an unsigned integer. If the machine supports n-bit integers, can we compute the number of 1-bits in O(log n) machine instructions? Can we compute the number of 1-bits in O(b) machine instructions where b is the number of 1-bits in the integer? Source: Commonly asked in job interviews for Software Engineers. I first heard it in 1996 when I was a graduate student. Solution: This article presents six solutions to this problem.

Build a Hydraulic Ram Pump - DIY The search for a "perpetual motion" machine is just about as old as civilization itself. And though we all know that such a gadget probably doesn't exist, there is a piece of equipment that comes pretty close: the hydraulic ram pump. The water ram (also known as a trompe) has been around for quite a while and was a widely used means of pumping water before electricity became common in rural areas. Strictly speaking, the ram pump doesn't create its own power but draws energy from the force of a moving column of water, usually fed through a pipe from a point more than 18 inches above the trompe. Although the hydro ram won't operate without a fluid power source, it will work indefinitely when water is present.

Practical Survivor Water procurement during a survival situation could possibly be your number one concern. The length of time you body will survive without proper hydration varies under different conditions. Increase in ambient temperature and activity will lessen your chances of survival. Window Socket – Solar Energy Powered Socket by Kyuho Song & Boa Oh The Window Socket offers a neat way to harness solar energy and use it as a plug socket. So far we have seen solutions that act as a solar battery backup, but none as a direct plug-in. Simple in design, the plug just attaches to any window and does its job intuitively. Designers: Kyuho Song & Boa Oh IBM 'Watson' Wins: 'Jeopardy' Computer Beats Ken Kennings, Brad Rutter (SETH BORENSTEIN and JORDAN ROBERTSON, AP) Machines first out-calculated us in simple math. Then they replaced us on the assembly lines, explored places we couldn't get to, even beat our champions at chess. Now a computer called Watson has bested our best at "Jeopardy!"
