The Cabinet Committee on Economic Affairs (CCEA) allowed state-owned Coal India Ltd (CIL) to pump methane gas trapped in coal beds of its existing mines. This move will open a new revenue stream for the world’s largest coal miner and help unlock several mines that have remained out of bounds because of the presence of the explosive gas that make mining unsafe.
Presently, rules and regulations prohibit mining firms from extracting Coal Bed Methane (CBM) during mining as the policy does not allow for simultaneous extraction of methane (CBM) and coal. Only those companies that successfully bid for mines with CBM are allowed to explore and produce such gas. The government auctioned 33 CBM blocks since 2001.
CIL holds at least 20% of the estimated 60 billion tones of coal resources in India. It has many coal mines in eight States that are estimated to have CBM reserves of 3.5-4 trillion cubic feet.
An artificial heart that can give patients up to five years of extra life has been successfully implanted for the first time, at Georges Pompidou Hospital in Paris, France. The equipment designed to overcome the worldwide shortage of transplant donors was produce by French Biomedical firm Carmat, a start-up funded by the Dutch-based European Aeronautic Defense and Space Company (EADS).
About Artificial Heart
- Powered by external, wearable Lithium-ion batteries.
- Inside the heart, surfaces that come into contact with human blood are made partly from bovine tissue instead of synthetic materials such as plastic that can cause blood clots.
- Uses a range of “biomaterials”, including bovine tissue, to reduce the likelihood of the body rejecting it.
- Weighs about 900g (around 2 lb) – nearly three times more than an average healthy human heart. It is expected to cost 140,000 to 180,000 euros in Europe.
- It mimics heart muscle contractions and contains sensors that adapt the blood flow to the patient’s moves.
- Intended to replace a real heart for as many as five years, unlike previous artificial hearts that were created mainly for temporary use.
