Space technology that can help us preserve our environment


Recommended Posts

Can such space technology like or satellites or microsatellites make their investsments in preservation of the environment on Earth? For example, such project like Sentinel-6 satellite we can observe sea level and other stuff that can help scientists make particular operation in environmental preservation.

It can tell us what needs to be done.  On the other hand it has been telling us what needs to be done for 60+ years and the only constant is insufficient work on doing what needs  to be done.

That`s a good point. I guess that such kind of space technology can help scientists to make appropriate measures to  prevent global warming and save environment from being completely destroyed.

Not just recycling.

Thermonuclear reactor (for power) + thermal ionizing chamber (to split everything into single ions) + magnetic trap (to separate the ions) + magnetic traps (to brake the ions) + thin powder containers (to store the resulting almost monoatomically thin powder of pure chemical elements) + mixer + additive printing device / 3d printer.

Gather all city junk, random stones, metal scrap, etc, pour it inside this plant, get powders of purified element, print new things.

Make a nearly-closed municipal ecosystem, cut your needs in ores, and leave the miners without job.

Scale it down to bring to the Moon.

No ore deposits are needed anymore. Every random stone consists of various metals and oxygen.

That`s a good point and good project to make. But still I don`t think that governments are ready to invest money in it. Most of them might think that it`s useless and waste of money.

Assuming this was used to to only get raw elements, how energy intensive would this be for a kg of non-food trash? Is it possible with today’s technology on a city-wide scale? Obviously for something like a mission to Mars it would be almost definitely worth it but here on Earth, on Earth can the energy be provided substantially?

A lot of. 
At the moment no time to get deep into calculations, but probably tens of MJ per kg.

But keeping your municipal ecosystem close to closed you gain the fact that you don't need to reduce metals from oxides, and you don't need a lot of new metal daily.
Also most of junk is organics, so you just need to turn it into CO2, H2O, N and then into ammonia and methanol to feed the algae.

On other planets (where you don't have coke, lime, fluorite, and so on at hands) it's probably just the only available option.

Getting back to my topic satellites are very important in our life. And the video you`ve shared with us proves it. Some sorts of sats and microsatellites help scientists observe melting of glaciers, track rare species of animals and control deforestation in some regions. So with the help of that sats scientists can affect on environmental preservation process.
