Steve Woz on our closed source education system

0

A very succinct message from Steve Woz on how our education system(s) kills creativity in its quest for a one size fits all approach to education…

This is so true all over the world… the waste of human potential is the greatest waste

TED | Michael Pritchard’s water filter turns filthy water drinkable

0

Turn any water into drinking water… $20 billion can provide safe drinking water for the entire world… this would an ideal stimulus plan…. healthier people can improve their own lives and contribute to their and society’s development

Star-Trek Traction beam discovered

0

The traction beam cannot lift your car or boat but it can move really really small objects. Who knows this may solve other mysteries like dark energy :) Here is the blurb from the article in ScienceDaily:

A team of Yale University researchers has discovered a “repulsive” light force that can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity. The team previously discovered an “attractive” force of light and showed how it could be manipulated to move components in semiconducting micro- and nano-electrical systems—tiny mechanical switches on a chip. The scientists have now uncovered a complementary repulsive force.

Happy Birthday! The Gasoline-Electric Hybrid Car is 100 Years Old

Treehugger has a great article on the hybrid car technology turning 100. Actually about a 100 years ago there were more electric or hybrid cars than pure gasoline / petrol driven cars.

Forward Osmosis- revoluntionary water treatment?

1

Cleantechnica has a post on Forward Osmosis. It is better explained here. The authors description in a gist:

…conventional desalination and reuse technologies use substantial energy. “forward osmosis,” exploits the natural diffusion of water through a semi-permeable membrane. Their process “draws” pure water from its contaminants to a solution of concentrated salts, which can easily be removed with low heat treatment — effectively desalinating or removing contaminants from water with little energy input.

The concentrated salt solution is probably a mixture of ammonia and/or carbon dioxide dissolved in water. The ammonia and CO2 are later easily boiled off and reused. The energy required for this quite less even low-cost solar heaters may be sufficient.

Fighting hunger with flood-tolerant rice

CNN reports that scientists after over 10 years of research have successfully developed a new strain of flood-tolerant rice through precision breeding. Read the article to know more about the inspiring work being done to positively impact the lives of hundreds of millions.

New Catalyst Paves The Path For Ethanol-powered Fuel Cells

0

This could prove to be a breakthrough for bio-ethanol based fuel cells. Current fuel cells are mostly methanol based which is a toxic chemical and have low efficiency.
Here is the ScienceDaily (2009-01-29) article:

Scientists have developed a new catalyst that could make ethanol-powered fuel cells feasible. The highly efficient catalyst performs two crucial, and previously unreachable steps needed to oxidize ethanol and produce clean energy in fuel cell reactions.

Durable $5000 Home Made from Recycled Paper

Local communities can probably leverage ideas like these to implement open-source design democratized green urban housing. BTW, how can you make a paper house fireproof? I understand that by using resin / coatings you make it waterproof but how it be made fireproof like bricks and not just fire-resistant?

Your thoughts / comments are welcome. Here is the link to the recycled paper house.

Surgeons could save lives, $20B by using checklist

This will probably be useful worldwide…

Eight hospitals reduced the number of deaths from surgery by more than 40% by using a checklist that helps doctors and nurses avoid errors, according to a report released online today in the New England Journal of Medicine.
