9 pictures of IFM International Forgemaster-Conference 2003 in Kobe Japan. I explained that with supposed 1/10000 remaining solar energy daily due to greenhouse effect each day leads to 3K increase of world temperature in one century (we are not far from this prediction 20 years ago), see my table publications. The target was to produce high efficient turbines made of special heat resistant steels for high efficient power plants with less combustion of fossil based primary energy. This was the reason for an investment of a new 85MN Press at Saarschmiede GmbH.
