Hans Rosling and the magic washing machine | Video on TED.com - 77 views

  •  
    What was the greatest invention of the industrial revolution? Hans Rosling makes the case for the washing machine. With newly designed graphics from Gapminder, Rosling shows us the magic that pops up when economic growth and electricity turn a boring wash day into an intellectual day of reading.

Making Oil from Plastic - 34 views

  • Making Oil from Plastic
  • Tons of plastic from Japan and US is left afloat in the Pacific Ocean, which is endangering marine life significantly.

  • The machine is effective in recycling different kinds of plastic into oil.
  • Utilization doesn't just take into account the 20 percent of recycled plastic. But it also considers the incinerated 52 percent used for energy recovery like generating electric power or heat. Akinori Ito says "If we burn the plastic, we generate toxins and a large amount of CO2. If we convert it into oil, we prohibit CO2 production and at the same time, increase people's awareness about the value of plastic garbage"
  • Oil from Shale: Oil can be extracted from this fine grained, organic rich, sedimentary rock through pyrolysis, thermal dissolution or hyderogentation. Shale contains high concentrations of organic chemical compounds known as Kerogen. From this solid mixture, oil is extracted through chemical process. Shale can be effective converted into combustible oil shale gas and liquid hydrocarbons (shale oil). Global deposits of Shale are estimated to be around 2.8 trillion to 3.3 trillion barrels of restorable oil. Planet earth is blessed with about 600 known oil shale deposits, most of which is found in United States of America. Although several countries have oil hale deposits, known deposits of economic importance is found only in 33 countries.

Electricity FERC - 10 views

  • Regulatory Changes by the Federal Energy Regulatory Commission
  • FERC Orders 888 and 889
  • On April 24, 1996, FERC issued Orders 888 and 889, which encourage wholesale competition.  The primary objective of these orders is the elimination of monopoly power over the transmission of electricity.  To achieve this objective, FERC requires all public utilities that own, control, or operate facilities used for transmitting electric energy in interstate commerce to: file open access nondiscriminatory transmission tariffs containing minimum terms and conditions, take transmission service (including ancillary services) for their own new wholesale sales and purchases of electricity under open access tariffs, develop and maintain a same-time information system that will give existing and potential  users the same access to transmission information that the public utility enjoys, and separate the transmission from generating and marketing functions and communications.

  • Recovery of stranded costs is perhaps the most contentious issue confronting regulators in promoting competition.  Stranded costs (or assets) are costs that have been prudently incurred by utilities to serve their customers but cannot be recovered if the consumers choose other electricity suppliers. One study has estimated current stranded assets at $88 billion, and estimates of projected stranded costs range from $10 billion to $500 billion. In its Order 888, FERC reaffirmed "that the recovery of legitimate, prudent and verifiable stranded costs should be allowed." FERC's directive is grounded in the belief that the recovery of stranded costs "is critical to the successful transition of the electricity industry to a competitive, open-access environment." For this purpose, direct assignment of costs to departing customers was selected as the appropriate method for recovery of stranded costs.

Intel: Light beams can replace electronic signals for future computers - SmartPlanet - 12 views

  • Here’s how it works, step by step: The transmitter chip is made of four hybrid silicon lasers. Light beams from the lasers each travel into an optical modulator. The modulator encodes data onto the beams at 12.5Gbps. The four beams are then combined and output to a single optical fiber, for a total data rate of 50Gbps. At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors. The photo detectors convert data back into electrical signals.
