Make your very own solar panel!  Here's how! Want to know how to Make a solar... - 0 views

  •  
    A solar cell is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon, and require huge factories, high temperatures, vacuum equipment, and lots of money. If we are willing to sacrifice efficiency for the ability to make our own solar cells in the kitchen out of materials from the neighborhood hardware store, we can demonstrate a working solar cell in about an hour.

Extra audio of Gazzaniga interview....AND Steven Pinker - 0 views

  •  
    "Gazzaniga has been a vocal scientific voice on the council at a controversial time -- with President George W. Bush twice vetoing legislation on stem cell research; the limiting of U.S federal funding for human embryonic stem cell research to a restricted number of cell lines; and other debates."

Avoid Car DVD Players Monster To Knock Your Door - 0 views

  •  
    As one of the most important car accessories, motorized Car DVD players just get hotter and hotter. Well, its hit may result from the visual digital impact that are becoming more and more unresistable to young people and the high tech technology that make me think we are geek. No doubt car DVD players have paved its landing success to SUVs and automobiles. They are fun, they are great but they also cause problems. The car entertainment systems like motorized DVD players had joined talking on cell phones and text messaging as the third potentially dangerous distractions that may cause fatal car accidents.

Medical devices powered by the ear itself - MIT News Office - 1 views

  • Health Sciences and Technology (HST) demonstrate for the first time that this battery could power implantable electronic devices without impairing hearing.
  • The devices could monitor biological activity in the ears of people with hearing or balance impairments, or responses to therapies. Eventually, they might even deliver therapies themselves
  • “In the past, people have thought that the space where the high potential is located is inaccessible for implantable devices, because potentially it’s very dangerous if you encroach on it,” Stankovic says. “We have known for 60 years that this battery exists and that it’s really important for normal hearing, but nobody has attempted to use this battery to power useful electronics.”

  • The ear converts a mechanical force — the vibration of the eardrum — into an electrochemical signal that can be processed by the brain; the biological battery is the source of that signal’s current. Located in the part of the ear called the cochlea, the battery chamber is divided by a membrane, some of whose cells are specialized to pump ions. An imbalance of potassium and sodium ions on opposite sides of the membrane, together with the particular arrangement of the pumps, creates an electrical voltage.
  • Low-power chips, however, are precisely the area of expertise of Anantha Chandrakasan’s group at MTL
  • The frequency of the signal was thus itself an indication of the electrochemical properties of the inner ear.
  • in cochlear implants, diagnostics and implantable hearing aids. “The fact that you can generate the power for a low voltage from the cochlea itself raises the possibility of using that as a power source to drive a cochlear implant,” Megerian says. “Imagine if we were able to measure that voltage in various disease states. There would potentially be a diagnostic algorithm for aberrations in that electrical output.”
  • “I’m not ready to say that the present iteration of this technology is ready,” Megerian cautions. But he adds that, “If we could tap into the natural power source of the cochlea, it could potentially be a driver behind the amplification technology of the future.”
  •  
    "For the first time, researchers power an implantable electronic device using an electrical potential - a natural battery - deep in the inner ear."

    "All of D-Lab's classes assess the needs of people in less-privileged communities around the world, examining innovations in technology, education or communications that might address those needs. The classes then seek ways to spread word of these solutions - and in some cases, to spur the creation of organizations to help disseminate them. Specific projects have focused on improved wheelchairs and prosthetics; water and sanitation systems; and recycling waste to produce useful products, including charcoal fuel made from agricultural waste."
