Reply to UIUC Researchers propose a new way to get fresh water from seawater, without the disadvantages of traditional desalination. They say that a vertical “capture surface” that is 210 m wide and 100 m tall, could extract enough vapor floating above warm oceans to supply 500,000 people with freshwater by lughnasadh
I see value in capturing the humidity there but they didn't receive the machine at all. Or did I miss it? I'm assuming it's just a standard dehumidifier at this point.

>“This trend mainly reflects the 4.5% increase in electricity produced from renewable energy sources (64.9% of total electricity), maintaining the consecutive growth since 2017”, explains the document.
So, less than 1% per year. Pretty modest compared to what the others in Europe have done. Especially considering their solar and wind resources.

I think it has been decking in cost per MWh historically faster than that but expect we would eventually plateau at some ridiculously low price.

Reply to comment by HuntingGreyFace in Exxon’s bad reputation got in the way of its industry-wide carbon capture proposal by Sorin61
That video didn't show what you claimed. You said "the biggest investors in oil right now".
It does say that Google and Amazon are applying their technology toward better oil extraction in partnership with oil companies. Not something most of us celebrate, but not what you believed was there.
It also mentioned that they have shifted their own energy consumption toward being 100% renewable energy over the last 5 years. I note that Google is also committed to being fully renewable 24 hours per day, which is going next level on the effort.

>It could absolutely be 1 TW/year by 2030. Solar always surprises. But if you try to allocate that to certain countries you will encounter huge resistance from experts on those countries, including governments of those countries. Also, manufacturing 1 TW/year is trivial compared with finding grid capacity to build it.
I guess we can hope that ever cheaper power will drive the process along.

Reply to comment by Heap_Good_Firewater in The IEA says humanity used the greatest amount of coal in 2022 in all of human history, and that this level of consumption will continue until at least 2025. One-third of all global coal goes to generate electricity in China, and India's coal use is growing at 6% per annum. by lughnasadh
A mitigating factor when you consider energy instead of power is that somewhere between 30 and 50% of energy in most cases is expelled as waste heat. Those thermal power plants and vehicle transport energy cases shouldn't be compared one to one with renewables.

The report says... >From 2022 to 2025, global electricity demand is forecast to grow 2.8% annually on average, or by an absolute of ~2 496 TWh. Renewable energy will provide the majority share of additional demand at 90%. The remaining gap of ~83 TWh will be covered by coal- and gas-fired power generation. The largest increases in coal burn are forecast for China (+5%), India (+7%) and Southeast Asia (+14%). Meanwhile, coal-fired power generation will continue to contract in the United States (-18%) while a return to a declining trajectory is expected for the European Union (-29%).
IEA consistently underestimates renewable growth. If history is any guide this report should be saying quite the opposite. That we have likely hit peak coal and fossil fuel consumption this year and that renewables are the champion that is doing this.
Edit: I expect this op report doesn't include these upgraded expectations. https://www.carbonbrief.org/analysis-ieas-renewables-forecast-grows-76-in-two-years-after-largest-ever-revision/

Smart people that have done the math claim we won't be able to create cost competitive power with fusion. it would still have been a win for humanity regardless if we achieve it.

It wouldn't work that way. They would specify a use case, along with the required properties, to narrow it down. Sounds like fun, really.

Reply to comment by pete1901 in Is the future of carbon-capture technology electrochemistry? | Colorado Arts and Sciences Magazine | University of Colorado Boulder by ProFoxxxx
A very high renewables grid is going to have an awful lot of power to use for other things, when in surplus. Tony Seba refers to that as super power.
We will be producing at 3 or 4 times the standard grid requirements at times. Some will go into storage, but not much. Then hydrogen production.
But put a good price on carbon and we will have lots of non carbon based surplus energy to tame climate change. I think where we put it will be more the question.

I'm 60 and only in the past 5 years have I thought that science is progressing fast enough to save my butt into the indefinite future.
So much has happened in the past five years in regards to the science required for indefinite lifespan. And it is only going to speed up. AI combined with the wave of doctorate level training.
I do wish we all had a Ministry of Longevity though to make it all happen much more effectively. Every boomer has a stake in this happening.

Most of the chatter I hear and see about intermittent fasting is focused on it just being a good way to cut calories for some. No magic involved.
Whatever works.
