So last post there was an immediate problem :
Our outdated technology has caused this issue, which must be resolved immediately. We cannot wait for a solution for 500 years. By then it would be too late.
But now we can afford to wait for synthetic materials and mining other planets? :
I'm referring to a society that not only has the ability and knowledge to create synthetic materials (including, if necessary, synthetic foods) from any available basic material, but also harvests whatever we need from all of the planets and asteroids in our solar system.
What happens between now and then?
We need to reduce demand. We need to reduce consumption.
There is one thing about the future I am absolutely sure of. It is a thing which is a most dangerous assumption which can only lead to more trouble. And that is the delusion that we are ever going to get resources from other planets.
Even though Titan, Saturn's biggest moon, is close by and has lakes and oceans of methane, I don't think energy will come from other planets in the future, either. We won't go after organic fuels that pollute the environment. There's a much easier way to get energy: the sun. About 10,000 times more energy comes from sunlight hitting the earth than is consumed worldwide as you read this.
It is possible to put huge solar panels in orbit around the earth and send the energy wirelessly to the earth's surface, using microwaves or laser beams, but it is not cost-effective to do so right now. That is, the current price of energy is too high right now.
But once a few solar panels are set up, the energy they produce can be used to pay for the installation of more panels in a way that grows exponentially over time. Soon, we could be flooded with free energy, and having the ability to ramp up production as needed.
But solar energy isn't the only new thing that's happening. On Sunday, the U.S. Department of Energy said it would announce a "major scientific breakthrough" this week. This came after the media reported that a federal laboratory had recently reached a major milestone in nuclear fusion research.
