www.intelligencesquared.com In the fourth installment of our iq2 Shorts series, Professor Michael Düren of DESERTEC argues that we can harness the African desert sun to power the world. The animation is adapted from our Switched On evening ‘Energy Game Changers’ from March 2012.

Really great video! We included it as part of our Video Of The Day tumblr – dothegreenthing.tumblr.com
Enjoyed the creative animation of an interesting point of view! We featured it today on GreenFlik . . . dot com.
Fantastic animation!! And I too love the undiluted German accent, it somehow has an association to science.
I think it has to go hand in hand. The governments need a prospect of a long-term stable energy supply and investors need stable governments for large scale investments in energy infra structure.
Question: Do we need stable African governments first, or will stabilisation occur when Solar Farming is in practice?
Yes, you can store electricity directly, e.g. in batteries. But if you want to store large amounts of energy, its much less expensive if you store it as heat in large tanks and convert it to electricity afterwards.
Can’t you store the suns light by converting it into electricity? Then you just use the electricity at night.
Gorgeous!
This has to happen, but there are so many concerns. Particularly, energy supply security… Will consumer nations be held to ransom by terrorists or unscrupulous national governments with control over the supply? I guess that’s why there’s an emphasis on providing benefits to the African nations, but what a job!
I believe AC was originally chosen because it is easier to transform low > high > low voltage for distribution and local consumption.
I love German Akzents
Over longer distance HVDC is more efficient because it loses much less electricity than AC.
wait i thought dc is less efficient then ac. isn’t it? that why we use ac then dc to power home.
Wow
