Printing Solar Panels

This is an interesting video of a company that is trying to print solar cells like you would newspaper. They are not the only ones trying this (we have featured Konarka before who hopes to do something similar), but these guys have a fun video to look at.

More from Nanosolar here.

With the cost of silicon solar cells going down, but still high, technologies like this will push the economical scales of solar technology. Look for the cost of solar to become so cheap that everything will be coated with it in the next 10 years. And frankly with the state of the world today, this sort of technology can’t come soon enough.

Shift Happens An Interesting Look At Our Exponential Times

Check out this very interesting video about the how information and information technology could potentially change our world. It makes a point that to be literate in the 21st century you need to know a lot more than you used to. I find the idea of the world working together to solve common problems, and create common knowledge both fascinating and inspiring.

An official update to the original “Shift Happens” video from Karl Fisch and Scott McLeod, this June 2007 update includes new and updated statistics, thought-provoking questions and a fresh design. For more information, or to join the conversation, click here.

Renewable Energy Roundup

Its Thursday, you know what that means. No, its time for the Renewable Energy Roundup!!!! (caps optional exclamation point mandatory) Time to wrangle all the eco-news that fell through the eco-cracks to get posted in a giant link frenzy. Hold on here we go.

Inspired by Keith’s comment on my post about living free, I found this little gem about freegans. I guess its more fun to call it freeganism than dumpster diving, but either way it is a good idea.

Could we be putting these things in our cell phones soon, charge them up by walking them around in our pockets? Check out these tiny generators that produce electricity from motion around them.

Germany wants to be 50% renewable by 2030. Meanwhile in America we are still bitching about increasing fuel economy just a little.

Hillary Clinton On Green Collar Jobs

I agree with every single thing she says. Except I wish she would go into more detail on the biofuels. It would be political suicide to talk to Iowans about the problems with growing crops for fuel. There would be a revolt. It is well known however that growing food crops to feed our cars is a bad idea. Perhaps as the primaries loom closer we can get a bit more detailed plans out of the candidates.

For The First Time Ever More Than Half The World Lives In Cites

world population day

For the first time ever, more than half of the world’s population now lives in cities. July 11 marks World Population Day and the focus is on South Asia, where the biggest cities in the world are growing quickly. Dhaka, Bangladesh, could be home to 20 million people in 10 years, according to the World Bank. This years theme is “men at work”, in which men are encouraged to help their wives and daughters gain a better life.

The global population has tripled in the last century. In 1988, the earth’s population was five-billion, in 2000 it was 6.06 billion and since then, it has been increasing steadily at the rate of 78 million per year. It is predicted that 7.3 billion to 10.7 billion people will be crammed onto the planet by the year 2050. It is estimated that 90% of this growth will be in developing nations. Nations that already have a hard time feeding and providing services to their populations. By 2030, towns and cities will be home to five billion people. The urban population of Asia and Africa will double in a generation.
