Wire Up Geothermal Heat With Graphene
Two Russian scientists discovered that graphene can have exceptionally large thermal conductivity, up to 5300 W/(m.K), something like 12,000 times better than copper and got rewarded with the Nobel Prize in 2010. Watch the video below showing how you can cut though ice with a graphene blade, using heat from your fingers. The Manoj Bhargava Indian billionaire thinks that graphene (carbon) cables could revolutionize how we extract heat from geothermal wells and distribute heat and invests in the technology. The idea is to abandon the concept of geothermal heat transfer through fluid motion, and instead use thermal conductivity of graphene to bring heat to the surface of the earth via wires, without moving material, pumps and pipes.

Texas Solar Tower Go Ahead?
What we love about the project are the video and music, but that’s about it.
Last year we reported about an Australian company promoting the design of a solar downdraft wind tower and expressed our skepticism regarding the energy efficiency of the project:

To our amazement, Environmission reported that Texas agreed to invest 1 million $ in the undertaking.

Furthermore, India seems to be interested as well:

India Ready to Pay Iranian Oil in Euro
New Delhi, March 23: India is likely to grant Iran’s request to be paid fully in euros for oil, against the current practice of partial payment in rupees… Reports quoting Mohsen Qamsari, director for international affairs of the National Iranian Oil Company, said, “Indians are interested in increasing oil imports from Iran and we welcome this matter in the event that it would be possible for us to receive payments in euros in our accounts.”
Wind-Coal Break-even in India
[source]
The cost of wind power has dropped below the price of coal-fired energy in parts of India (like Karnataka, Rajasthan, Maharashtra and Andhra Pradesh) for the first time as improved turbine technology and rising fossil-fuel prices boost its competitiveness, Greenko Group Plc said. The current cost to build wind farms in India is about $1.25 million a megawatt.
India opens world’s largest solar park
The newly-developed solar power park will be a 500-megawatt system using state-of-the-art thin film photovoltaic technology and should be fully completed by the end of 2014. It now has an operational capacity of 214 MW and has already become the largest such single location in the world, spread over 3,000 acres (12 km2) of mainly wasteland.
