'Watered Down' MOOC Bill Becomes Law In Florida | Inside Higher Ed - 10 views

  •  
    Florida Governor Rick Scott signed a bill into law last week to encourage the state's K-12 and higher education systems to use massive open online courses, or MOOCs. The bill Scott signed allows MOOCs, under certain conditions, to be used to help teach K-12 students in four subjects and also orders Florida education officials to study and set rules that would allow students who have yet to enroll in college to earn transfer credits by taking MOOCs.

Hydrogen vehicle - Wikipedia, the free encyclopedia - 13 views

      Is hydrogen sustainable? depends on the source. see this highlight.
  • While methods of hydrogen production that do not use fossil fuel would be more sustainable
  • The challenges facing the use of hydrogen in vehicles include production, storage, transport and distribution.
  • ...3 more annotations...
  • The hydrogen infrastructure consists mainly of industrial hydrogen pipeline transport and hydrogen-equipped filling stations like those found on a hydrogen highway. Hydrogen stations which are not situated near a hydrogen pipeline can obtain supply via hydrogen tanks, compressed hydrogen tube trailers, liquid hydrogen tank trucks or dedicated onsite production.
  • Hydrogen use would require the alteration of industry and transport on a scale never seen before in history. For example, according to GM, 70% of the U.S. population lives near a hydrogen-generating facility but has little access to hydrogen, despite its wide availability for commercial use.[64] The distribution of hydrogen fuel for vehicles throughout the U.S. would require new hydrogen stations that would cost, by some estimates approximately 20 billion dollars[65] and 4.6 billion in the EU.[66] Other estimates place the cost as high as half trillion dollars in the United States alone.[67]
  • Hydrogen fuel does not occur naturally on Earth and thus is not an energy source, but is an energy carrier. Currently it is most frequently made from methane or other fossil fuels. However, it can be produced from a wide range of sources (such as wind, solar, or nuclear) that are intermittent, too diffuse or too cumbersome to directly propel vehicles. Integrated wind-to-hydrogen plants, using electrolysis of water, are exploring technologies to deliver costs low enough, and quantities great enough, to compete with traditional energy sources.[2]

Why Teachers Need Social Media Training, Not Just Rules | Spotlight on Digital Media an... - 6 views

  •  
    Under a new set of social media guidelines (pdf) issued by the New York City Department of Education, teachers are required to obtain a supervisor's approval before creating a "professional social media presence," which is broadly defined as "any form of online publication or presence that allows interactive communication, including, but not limited to, social networks, blogs,  internet websites,  internet forums, and wikis." 
  •  
    Great insight into educating teachers about the use of social media within their schools so that they can help students navigate these waters as well.

Startup turns carbon dioxide into fuels - 1 views

  • Today, carbon dioxide (CO2) is a hot topic. Scientists around the globe are searching for ways to store, dispose of, or prevent the formation of the greenhouse gas, which is a major driver of global climate change. Liquid Light hopes to take this concept one step further and harness waste CO2 as a source of carbon to make industrial chemicals and fuels.
  • Take CO2 and mix it in a water-filled chamber with an electrode and a catalyst. The ensuing chemical reaction converts CO2 into a new molecule, methanol, which can be used as a fuel, an industrial solvent or a starting material for the manufacture of other chemicals.
  • Bocarsly likes to call the process "reverse combustion" because it is like running a burning reaction backwards. Instead of burning fuel and oxygen to produce CO2, the CO2 converts back into fuel and oxygen.
  • ...2 more annotations...
  • Cole set up a flask containing a solution of CO2 and a pyridinium catalyst dissolved in water. In place of sunlight, which emits a broad spectrum of wavelengths of light, she shined on the flask a blue light-emitting diode (LED) because it gives off certain wavelengths that are highly efficient at driving the reaction. In the flask she placed an electrode that is activated by particles of light, or photons. "We used a semiconductor electrode that would allow us to substitute light for electricity," said Cole.
  • The Princeton scientists did some additional studies, and made a surprising discovery: They could turn CO2, which contains only one carbon, into a compound with a carbon-carbon bond, which vastly increases the possibilities for creating commercial applications.

      I like the idea of Skyping with people from other countries.  I could get the kids to come up with a list of questions first.  My biggest question is HOW do I connect/find someone from another country?

The closer you are to the target, the more cups of water are donated to people in need around the world.
