Comment Compare an acre of biofuel corn to acre of solar (Score 1) 217

Chat-GPT says solar is extremely more productive in terms of energy opportunity per acre compared to corn for biofuels.

There are over 29 million acres farmed for biofuel production.

https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Farevonenergy.com%2Fnews%2F...

Anyway, this is very unintelligent, all around. And that is polite.

Chat GPT Answer:
Short answer: solar absolutely crushes corn-for-ethanol on an energy-per-acre basisâ"by roughly 35â"45Ã-- each year.

Why (using U.S. medians):

Corn â' ethanol: Typical yields are ~460â"480 gal ethanol/acre/yr (e.g., 462â"484 gal from University of Nebraskaâ"Lincoln extension). Ethanolâ(TM)s energy content is ~76,000 Btu/gal. Thatâ(TM)s about 10.3â"10.8 MWh (thermal) per acre per year.
Farm Energy
CropWatch
Integrated Pest Management

Solar PV: Utility-scale solar delivers about 394â"447 MWh of electricity per acre per year (nationwide median energy density from Lawrence Berkeley National Laboratory / DOE).
The Department of Energy's Energy.gov
Energy Markets & Policy

Comparison (annual, per acre):

Corn ethanol: ~10â"11 MWh (thermal).
Farm Energy
Integrated Pest Management

Solar PV: ~400â"450 MWh (electricity).
The Department of Energy's Energy.gov
Energy Markets & Policy

Ratio: Solar yields â 35â"45Ã-- more useful energy per acre.

Notes:

This ignores ethanol co-products (animal feed) because the question is about energy per acre.

If you convert to miles driven, the gap widens further because EV drivetrains use electricity much more efficiently than internal-combustion engines burning ethanol. (Same acreage â' far more vehicle miles with solar-powered EVs.)

So you're saying some guy visited and had a complete laptop "mounted" to his front side so he could stand and use it?

I'm imaging a conversation with such a person. Or seeing someone waiting for public transit, standing there using a computer (one would probably get accosted doing this).

As I figured, everything you can think of exists, here's something like you described:

There are actually some interesting quantum data and simulation angles they could have taken. Quite interesting as far as thought experiments go.

Regarding the movie, I can't see any human derived drivel being of any use to an advanced civilization (maybe they are looking for ways to destroy natural ecosystems on a planetary scale...).

Comment Review before Sending (Score 4, Insightful) 33

This is actually a story about people who don't check their work ("bad employees" is the term I would use).

All of the problems noted are due to people not taking the time to "LOOK AT WHAT THEY ARE SAYING".

These are people that are willing to send out results without review. They think they know what they sent, but they don't actually know.

They are the problem, not the AI. They are lazy.

Meeting transcripts are fabulously useful. My notes are keywords now, which I can then cross reference with the transcript after the meeting.

As the article makes clear, much care needs to be taken with such source material as well as information derived from them.

In this case the AI did what it was told, summarizing everything. This is easy enough to avoid, here's a sample prompt:

For the meeting transcript below, please provide:
1. To Do List - Provide a list of follow up Tasks by Party.
2. Issues - Identify, classify, and provide details around any issues mentioned.
3. Technical Discussion - Identify and summarize any technical discussions.

Guidelines:
- Ignore unrelated personal commentary.

I was wondering about this "elite cycling is likely quite a bit cleaner now".

Proof is simply performance, and mountain times in the Tour de France have slowed since the EPO days.

Here's the analysis, scroll down to the graphs, they are very clear.

Comment Have Search Providers Pay for Access (Score 1) 134

Ideas anyone? Here's mine.

This only applies to sites that want the revenue. Sites that just want the exposure would leave things be.

Anyway, allow websites to require payment from commercial scanning services (search engine or otherwise).

Enforce through logs and "slightly" poison data for identifiability.

Use extremely punitive fees to enforce ($250,000 per article, like sharing a movie..., scanned should be a good start, that would quickly get very painful). Get the fines into the 10s of millions. There are trillion dollar companies.

I believe this can be used for Disney to get compensation as well. Proof that their images have been trained is simply asking for it to create a copyrighted character. How could it do that if it wasn't trained on such???

And I'm not saying Trump's policies are causing the sharp drop in CEO confidence since the start of 2025, but the timing is suspect (down to COVID and 2007 crisis levels).

I imagine that impacts hiring and discretionary/capital expenditures at companies.
