Break through in geothermal drilling: Electric pulses used to smash stone.
Kjell Gunnar Bleivik 02.06.2010 Staus: Latest update 02.08.2010 May be updated with additional information.
"It has long been known that there is an enormous energy potential from earth heat. Now a new revolutionary drilling technique may make this a reality. Using electrical pulses to smash stone it is possible to drill 12 meter per day to on tenth of the price using the old technology."
According to professor Arild Rødland there has been a break through in geothermal drilling. Heat from the earth, 2 km below the surface, can give large quantities of energy. Earth heat can give 100 times more energy than waterpower, but then you have to drill deep and it has been expensive. In today's Norwegian news, Rødland said that there has been a break through in geothermal drilling. Using electrical pulses, it is possible to drill 12 meter per hour to a price only 10 percent of former technology.

"Global investment in renewable energy surged 60 per cent to $148 billion (74.3 billion) last year."
Global investment in renewable energy surged 60 per cent to $148 billion (74.3 billion) last year and is still accelerating despite the slowdown in the wider economy, according to the United Nations. Renewable energy in "green gold rush" is the heading used on Times Online July 1, 2008.

Salt power plant: Where the river meets the sea.
Kjell Gunnar Bleivik 10.26.2008 Staus: Will be updated with additional information.
"When freshwater meets saltwater, for example where a river flows into the sea, enormous quantities of energy are released."
Norwegian statkraft are building the first osmotic power plant in the world. When freshwater meets saltwater, for example where a river flows into the sea, enormous quantities of energy are released. Osmotic power plants can be constructed anywhere were freshwater flows into the sea if the salt concentration is sufficiently high.
Again salt is a key component like it is in solar power plants where melted salt is used to store solar energy that is produced in the day whene the sun shines, see the first video below. Einstien once said that imagination is more important than knowledge. So what is the potential in Sahara with desalted water to produce fresh water and salt? And if it is solved on the earth, space lifts could pump salt water to a geo stationary space station, and transported to the moon and mars. Then the California academy of sciences has the solution to build a good environment for human beings. It is too early to know the futue. At present, we fight about limited resources on a limited planet, while space and energy are for practical purposes unlimited out there.
