Without fossil fuels, the world MIGHT be lucky enough to support 1.5 to 2 billion people.

More energy and material resources are needed to meet basic needs (schooling, health care, etc.). These lead to more prosperity and the rise of a middle class, which in turn means even higher resource consumption (e.g., energy and material resource cost for homes, private vehicles, appliances and electronic gadgets, etc.).

The assumption that we will automatically go back to breeding large families is perhaps not 100% accurate for cultural reasons. We might even see fertility rates dropping even further as mass media and consequences instill a collective cultural awareness that abundance is not coming back any time soon.

It is called a "Trompe" (compressed air) These systems work very well are clean and can produce not only energy but more importantly has the ability to travel large distances without loss unlike current electrical systems.
jonouk wrote:Trompes dont work that way you dont need to pump anything you just dig long shafts generate the compressed air the water then returns upwards and continues on its journey. In fact you can create as many of these as you like without using or losing any resources. As for getting water up hill again this can be done easily via a water ram jet but that is not required for tromp system
Google them at look at the design works as i say it free and TBA its much better than hydro as you can do more things with compressed air such as refrigeration, electric, run tools, run your car etc Sure if you dont have a river other will and you just share the air!
You are clueless. There is no free lunch or perpetual motion machines. A trompe is a way to use the potential energy of falling water to compress air. They work but the energy is derived from the difference between the intake elevation of the water and the outlet elevation.jonouk wrote:Trompes dont work that way you dont need to pump anything you just dig long shafts generate the compressed air the water then returns upwards and continues on its journey.
