Despite there is already synthetic diamonds better than natural diamonts, in many aspects, and clear (not yellowed synthetic diamonds of the past), its still very expensive, near the cost of natural one, or maybe even more, since a good deal of diamont market price it's marketing ratter than just be rare.

And so, due energy required, you put much more energy and consequent CO2 on atmosphere, in the process to creat synthetic diamonds than the CO2 it holds in the diamond body itself.

The sun eneryny released it's often not well explained or used wrong, There is the sun light that reach Earth and the sun light released by the Sun itself per second. If we would calculate the area of Earth in the side (daylight) and calculated the area of the imaginary sphere with the radius from Sun to the Earth's orbit, and remamber that Sun light take 5 minutes to reach Earch... It's a ratio in the order of billions.

light speed :300.000 km/sec
5min = 300 sec
Distance Sun to Earth = 90.000.000km
Earth area (flat calculation since sun light reach surface as flat) = earth radios elevated to cube then x 3,14. Then we get 127.451.472,74 square km for Earth solar area (side shined by sun).

The sphere from Sun (sphere center) to Earth's orbit would 90.000.000 x 90.000.000 than this value x 3,14 x 4. A insane number. 191.736.000.000.000.000 square kilometer
Earth side direct to the Sun have a solar area 1,5 billion times smaller than the sphere from Sun to Earth orbit.

I think the energy released by the Sun in 3 second it's more than humanity consumed (as electricity or thermal from fossil fuels) since industrial revolution.

Edited :I will need to rework my calculations, since the time to sunlight reach Eath it's more than 5 minutes as I imagined. It's 8 minutes and 20 seconds and not 5 minutes as I imagine.
So, I bet than less than 1 seconds of SUN energy it's more than humanity used since industrial revolution.


I did a second mistake, since I have to consider how much of the enrgy from Sun that reach Earth it's equivalente in relation to the enrgy consumed by humans in 1 day.
So maybe humanity consumed even lee than I suposed before.

Really that's remarkable though, because it's a step toward being able to manipulate subatomic structures, which I think will be game changing somewhere far off in the future. Something akin to the Star Trek replicator.

99.999999% of sunlight is wasted into space. We haven't even scratched the surface for the potential to manipulate our environment. This accidental increasing of CO2 and resultant acceleration of warming will look like child's play in the future.

Your using the same formula for area of a circle and sphere. How does the transit time figure in? And I suspect there is more energy in a single solar prominence than mankind has used.

The cycle of life is the definition of sustainable. Life is what CREATED the soil.

Artificial chemicals are already ruining the soil, and we are using too much water, and we are polluting at a massive scale.

Artificial nitrogen fertilizer is a huge part of climate change - carbon is leached out of the soil, AND nitrogen becomes nitrous oxide. Which is about 8X stronger a greenhouse gas than METHANE.

We have monoculture - this is the opposite of how life naturally works. Diversity is strength, and diversity is sustainable.

Our current factory farming system is very fragile, and it will fail.

We have to change to a system that BUILDS the soil, and that sinks carbon into the soil. We need to have as many different plants and animals as possible, being raised together. We need to grow all food as close to where it is eaten, as possible. We need to return all nutrient streams back to the soil. Our current sewage system is not sustainable.

In the final step of my calcultation, my final mistake, I took 1 day of sun energy (that reach Earth) as 1 day of human energy used. But what we use it's less than 1% of the solar energy that reach Earth, since if 1/2 of Sahara desert if covered with solar panels could provide energy for the entire human poplation.

I maybe 0,0001 sec of SUN total energy (not just what reachs Earth) it's probably more than humanity have ever used since industrial revolution.

The ideal energy solution would be a Dyson SPhere.

Part of diversity (of humans) is sustaining a large number of them at various levels of health, genetic predisposition, skills, and environment. Returning to less productive means of farming will certainly cause the death of many people. That may be good from a "survival of the fittest" standpoint, but it's not humane and works against diversity.

Current factory farming is a miracle and works wonderfully to produce an unprecedented amount of food. The world is nearing toward practically no starvation, which I'll probably see within my lifetime.

Nothing is sustainable, and the need for eventual adaptation to changing circumstances is assured. It may be that some of your proposed solutions are what is needed, but that comes at the expense of increased labor and energy inputs. We'll need to solve the energy and labor problems first.

There's this romantic idea that a small local farm with a guy gathering produce in his pickup truck is more energy efficient than the huge combines that harvest produce and the large trucks/ships that send it to far reaches of the world, but that simply isn't the case. Enormous machines are more energy efficient than a bunch of smaller, less energy intensive machines. The number of miles the product has to travel is almost irrelevant.

Besides that, who's going to give up fresh produce in the winter? We'll all go back to boiling/canning our fruits and veggies to make it through the 10 months of the year the produce isn't locally available?

All Darc — Comparing the total of human energy use to the total of something else is ultimately beside the point. Seasteading comes before Dyson Spheres.

Suppose the truck is a Tesla pickup?

Returning to less productive means of farming would be bad. Moving forward to vertical hydroponic robot grocery stores would be good.

Smaller, more distributed farming might be feasible in the future, but as of right now it is not.

I suspect when we solve our electricity problem to the point of having it for practically free combined with advances in robotics and more sophisticated automation, we'll be able to utilize small spaces and get high yields while reducing negative externalities.

If labor was near zero marginal cost for things like pest control, we'd have no need for pesticides. The robots could be pulling weeds, applying just the right nutrients exactly where needed, and harvesting when each plant is at peak rather than needing to harvest everything at once. Perhaps crops wouldn't need to be plowed under every year too.

I haven't read Jeremy Rifkin's book yet, but I think it's probable that we'll continue technological progress that approaches zero marginal cost goods. Of course, that will present whole new problems, but at least it gives us mere humans something to do.

Robots don't need to pull weeds, they can just poke them back underground while they're still sprouts too small to grasp.

Hydoponics is demonstrable technology. Pick and place robots are a thing. It's just a matter of stacking them vertically.

They called moving or elevating the track “extreme.” Instead, they recommended building temporary flood barriers that can be installed along the river before a storm, and then removed “to maintain aesthetics and passenger views.” Those walls would require 12 to 30 days to put up, and would cost $24 million per mile of track.
Sure, that will work flawlessly.
