Greece Could Seize Personal Assets; Portuguese banks gamble with government debt - ValueWalk Greeks have to declare all their wealth From January 2017, 8.5 million Greek citizens have to file a declaration of their belongings. The government is on the hunt for real estate, jewellery, art and even cash – outside the banking system. Before government implements new tax, a directory of the soon-taxed wealth has to be prepared.

Tesla's Big Mistake? While experimenting with a long, thin 'secondary' coil from a Tesla Coil, I suddenly connected up several things in my mind which had been separate up to that moment. After years of messing with Tesla Coils, I finally see what Tesla was up to with single wire transmission, with resonant coils, and with longitudinal waves. See if the following doesn't make sense.

In Sweden they are building high quality multifamily wood prefabs that we can only dream about here There are a few things we obsess about on TreeHugger, including modular prefabrication, tall wood construction and digital design. One doesn’t usually find them all in one place in North America, but in Sweden, it’s almost the standard. Lindbäcks, a 90 year old company in northern Sweden, is truly taking modular construction to new heights, cranking out apartments, condos, student housing and seniors buildings a rate of twenty units per week. Mother Earth: Waste Oil Heater You say the skyrocketing cost of oil, electricity, coal, and other fuels has you scratching for a less expensive way to heat your shop, garage, or home this coming winter?Well scratch no further! Because MOTHER is here to tell you about a dandy little furnace that her researchers have developed -- which costs next to nothing to build and is even less expensive to operate (since it burns the used motor oil that tens of thousands of service stations across the country will still give away free to anyone who'll haul it off). It's Cheap, Clean, and Environmentally Sound! Yep.

50 Tools Man is "weak in himself, and of small stature," wrote 19th-century essayist Thomas Carlyle. Yet, with tools, "the granite mountain melts into light dust before him, seas are his smooth highway, winds and fire his un­wearying steeds." And this from a guy who never felt a 5800-rpm circular saw scream to life in his hand. While much has changed since Carlyle's day, one thing hasn't: We need tools to build, repair and maintain the mechanical world in which we live. With these 50 tools, you'll be ready for just about any project--whether it's melting mountains or swapping out the kitchen sink. 1.

Our Simple DIY Home Solar Power System Bringing some of the benefits of electrical power to our off-grid home has been a hit-or-miss affair. Over the years we’ve tried some very simple approaches to lighting and small battery recharging for our flashlights, such as hauling a 12 volt car battery to a small rural school about a half mile away every time it needed to be topped up. This was time consuming and inefficient. But we didn’t want to lose the feel of our simple home by bringing in a large generator and the jugs of gas needed to run it, and the prospect of setting up a wind turbine or solar array seemed expensive and a technological eyesore in a natural setting. …developing Eartheasy.com using a dialup internet connection on a phone line strung through the woods was challenging… Today, with the help of a local expert on off grid home solar power and alternative energy systems, we have the best of both worlds.

Household Cleaning Tips from WomansDay.com - How to Clean House A few years ago, I found out that I’ve been cleaning all wrong. I was in a hotel room, when a maid came in and sprayed a solution on every surface…and then left. Right when I thought she’d forgotten, she returned. She wiped for less than two minutes with a thin dry cloth, and the whole place sparkled. It had, frankly, never occurred to me to let one solution do all the work, so I asked her what she’d used. To protect the revolution, overcome the false secular-Islamist divide - Opinion It is impossible to exaggerate the significance of the momentous events that have drawn global attention to Egypt as its people continue to struggle with the unfolding drama of their revolution. There are two evidently opportunistic events that have come together to signal a dreadful attempt by the Muslim Brotherhood to claim the entirety of the Egyptian revolution for themselves, pretty much on the same model that the Shia clerics hijacked the Iranian revolution of 1977-1979 - with the crucial difference that Egyptians in their tens of thousands have poured into their streets and are far more alert and vigilant to protect the totality of their revolution than Iranians were more than thirty years ago. The first event revolves around President Morsi grabbing (and then rescinding) more power than he was granted by the free and fair election that - with a narrow margin - sent him to the presidential palace. But the devil is in the details.

Solar Slab Using large super-insulated water tanks to inter-seasonally store solar hot water is popularly known as the Sonnenhaus concept in Germany, Austria and Switzerland. The water tanks vary in size from 40,000 litres for a standard house to up to 200,000 litres for apartment buildings and usually cost between £1.50-£2.00/litre. Sonnenhause owners boast heating bills 50% lower than the occupants of Passive Houses. The Solar panels and Water tank can be a costly addition to the construction budget and they can take up quite a bit of room. In order to explore this concept a super-insulated 10,000L Hydro Thermal Energy Store (below) was connected to 24m2 of Solar tubes in Cork in 2008, this reduced the clients heating/hot water bill by 65%. 24m2 of drain-back solar thermal tubes heat the water in the tank which reaches over 90 degrees most summers.
