Video: Civilisation types

No comments
In this lecture, theoretical physicist Dr. Michio Kaku talks about the types of civilisation. A Type 1 civilisation would correspond to a Buck Rogers type civilisation, type 2 which would correspond to a Star Trek type civilisation, and type 3 which would correspond to a Star Wars type civilisation (specifically The Empire).

Apparently we are currently a Type 0 Civilisation, but transitioning towards a Type 1 civilisation, and according to current calculations we will reach Type 1 in approximately 100 years, but that this transition from Type 0 to Type 1 is also the most dangerous phase and that some people fear this transition. More details are in the video itself.

Video: Why batteries are primitive

No comments
This is an interesting video I found on batteries. In this video, the theoretical physicist Dr. Michio Kaku explains why current battery technology is primitive, that today's batteries have far less energy per kilogram compared to petrol. The future possibilities look very interesting indeed - including using lots of carbon nanofibres or graphenes (a graphene sheet is a 2-dimensional layer of carbon atoms) to increase storage capacity dramatically, once nanotechnology matures of course.
