Global Village Energy Project: GVEP is a partnership of UNDP, World Bank, donor governements and NGOs for sustainable rural energy development.  ITDG – the Intermediate Technology Development Group – is the new host for the GVEP Technical Secretariat.  The site has a useful database of documents and pointers on renewable energy work around the world.   They participate in several EU programs on RE.  A brief 2003 survey of 9 related programs is online.  10:20:39 PM  permalink  

Copernican Inversion: Interesting new tool for making offline demos and traning versions of web apps.  I wonder if it could be used for creating test suites and exercising web apps.  Based on proxy emulation.  From Dan Grigsby.  4:48:51 PM  permalink  

Solar lanterns to light up 1,000 villages:  A product that is getting more popular in developing countries.  "As many as 660.000 houses in 1,000 villages in the State will get at least one solar-powered lantern as part of a `self-village energy security programme' involving the State Government and the Union Ministry for Non-conventional Energy Sources (MNES). This is part of a scheme to electrify `remote' hamlets using renewable energy..  The 1,000-village electrification project would cost Rs. 100 crores ($20 m). The MNES would provide 90 per cent of the funds and the State the rest. The project is to be facilitated by Karnataka Renewable Energy Development Ltd. (KREDL). The Managing Director of KREDL, B. Shivalingaiah, said the organisation was identifying the 1,000 villages. Villagers would initially have to pay Rs. 40 to Rs. 50 a month under the scheme, he said. "  4:36:59 PM  permalink  

Technology already exists to stabilize global warming: Article published in Science identifies portfolio of options to cut emissions now.  They refer to a stabilization triangle composed of emission reduction wedges:  "Keeping emissions flat for 50 years will require trimming projected carbon output by roughly 7 billion tons per year by 2054, keeping a total of ~175 billion tons of carbon from entering the atmosphere [graphed as a triangle]. We refer to this carbon savings as the "stabilization triangle."

To keep pace with global energy needs at the same time, the world must find energy technologies that emit little to no carbon, plus develop the capacity for carbon storage. Many strategies available today can be scaled up to reduce emissions by at least 1 billion tons of carbon per year by 2054. We call this reduction a "wedge" of the triangle. By embarking on several of these wedge strategies now, the world can take a big bite out of the carbon problem instead of passing the whole job on to future generations. "

Geothermal cooling for Toronto: "One of the world’s largest green heat systems has been commissioned in Canada’s largest city.  Enwave’s Deep Lake Water Cooling system can provide cooling for 130 office towers in the downtown core. The system pumps water of 4°C temperature from a depth of 83 m below Lake Ontario, which is used to chill Enwave's cooling plant before it is distributed to customers for air conditioning.

The earth energy system is used in cooling mode only, after which it is distributed for potable water consumption throughout the city. The project produces enough air conditioning for 20 million square feet of office space, and initial customers include the Air Canada Centre, Metro Toronto Convention Centre, Royal Bank Plaza, TD Centre and Steam Whistle Brewing. .. Compared with traditional space cooling, the system reduces electricity use by 75% and will eliminate 40,000 tonnes of CO2, equal to taking 8,000 cars off of the streets. It also frees 59 MW from the Ontario electrical grid."  4:15:19 PM  permalink  

Axis Network Camera HTTP Authentication Bypass Vulnerability:  Amazing securty hole:  Axis makes widely used networked surveillance cameras.  They have an onboard website for administration -- and that website is easily compromised.  Furthermore, it's reported that many of these cameras are open on the public internet and can be found with google (not even a robots.txt file to prevent indexing).  Incredible that a security products company would release such a buggy product.  And it's also reported that the company didn't respond to hacker reports (normally companies issue info and an update before the hacker goes public.)   "A vulnerability has been identified in several Axis Network Cameras, which can be exploited by a malicious person to bypass user authentication. Normally a user is required to input a username and password before access is granted to "http://[victim]/admin/admin.shtml". However, by sending a HTTP request with an extra "/" before the "admin" folder, it is possible to bypass the authentication completely."

Robocop Now in Beta: "If you're in New York City when the Republican National Conventions kicks off next week, watch for police officers watching you with extra sets of megapixel peepers. The Federal Protective Service has outfitted patrol officers with helmets embedded with wireless video cameras. The images from the helmet-cams and traditional surveillance cameras mounted in federal buildings are streamed to a headquarters-on-wheels where deployment decisions can be made. ..

The wearable component of the Federal Protective Service's system is more akin to two projects in development at UC Berkeley. As reported on TheFeature earlier this year, smart firefighter helmets will provide emergency personnel with an "augmented reality" display that overlays text and images onto their view through the helmet. Meanwhile, command and control officers can help guide the rescue efforts by sharing the view of the firefighters inside a blaze.

The police system is also quite similar to UC Berkeley professor Ken Goldberg's Tele-Actor, a "human robot" sporting wireless Web cams and microphones. Groups of online participants can collaboratively control the Tele-Actor as "it" moves through remote spaces. For example, in one experiment a class of high school students "visited" a restricted biotechnology laboratory using the Tele-Actor as their collective avatar. "  12:16:59 AM  permalink  

Made to Order - How industrial design became a weekend hobby: Many examples of customization (and "wrangling"), like fitting computers into other cases, modifying cars, playing The Sims, using rapid prototyping machines, and vendors like cafepress.com.  About rapid prototyping machines (aka "3D printers"), check out the Solidscape: T66 ($50k), and Z-corp (with a cool GIS application).  12:09:49 AM  permalink
