DDWFTTW energy feedback loop for windmill?

A variation on the Directly Down Wind Faster Than The Wind (DDWFTTW) Boat. First the drawing by Andrew Bauer from 1969 of a cart or boat. Bauer-Faster-Than-The-Wind.pdf

Click on image below for larger / sharper image.

Now a fixed windmill version. Can V C (Velocity of Car) be replaced by V B (Velocity of air Between airscrew & turbine)? See formulas by Thin Air Designs. Click on image below for larger / sharper image.


The airscrew "pulls" in a larger column of flowing wind, than a windturbine. (In the diagram below the wind direction is left to right.)


Will this generate more power than the turbine by itself that utilizes a smaller cross-section of the wind that is flowing by? (Betz law).

Thin Air Designs who made a Faster Than The Wind cart say:
The only use we *intend* for it to have is:
1) to keep us occuppied during the non-windy season.
2) To demonstrate that it's a bad idea to try and substitute intuition for science.

However, it does have some interesting aspects. One such aspect is the somewhat bizarre outcome that you can theoretically harness an unbounded amount of energy from the wind - if your windmill is allowed to move through the wind. A traditional windmill has a very definite limit to the amount of power it can produce for a given amount of wind. However, a moving windmill can continue to produce more power as it moves itself through the wind.

It's hard to say whether this will become any sort of practical reality, but there are folks using the principle - including our sponsor Joby Energy.


Discussion added october 22: E-mail from Professor Mark Drela of MIT:

Ansgar,

I don't know what "similar effect" you are referring to.

> Using your terms in the Power Analysis: Instead of V-W and V-W+ΔW for

OK, but the prop will require power to do this.

> For the turbine the prop wake is the input: instead of V you have W
> +ΔW , I am not sure what the speed would be behind the turbine... is
> ΔV then equal to ΔW ?

The dW_t behind the turbine simply depends on how much power it's
producing, and can be almost anything.
The maximum power is produced when
dW_t = W * 2/3,
in which case the wind behind the turbine is
W-dW_t = W - W*2/3 = W/3
This case is the Betz limit.

> Is it more effective than a standard wind turbine because it utilizes
> a larger streamtube than one dictated by Betz law?

Sure, blowing on the turbine will allow it to make more power. But this
blowing itself requires power, and the net power will be less than
without the propeller.

Osmotic Power aka Blue Energy aka Salinity Gradient Power to 'pump' water out of NL instead of a "gemaal"?



Norway has an Osmotic Power plant.The plant is driven by osmosis that naturally draws fresh water across a membrane and toward the seawater side. This creates higher pressure on the sea water side, driving a turbine and producing electricity.


Why not use Osmosis to `pump` fresh water out of Holland instead of creating electricity?



These guys (PDF) thought about using osmosis to create electricity to power a pump ( gemaal )at Lauwersmeer. If you skip the electricity production and just use the Blue Energy pump directly, it should be less expensive.

Skadi Rio Power X Prize -> Greenchoice !

Update 3:
Hallo John,

Folmer vroeg mij of ik u wilde mailen over de kwaliteit van de wedstrijd najaarstraining dit jaar.
Het gaat dit jaar beter dan de afgelopen jaren. Bij de dames gaan 16 dames mee naar Brugge. Dat er een dames 8 komt is zoals altijd wel een zekerheid.
Bij de heren gaan er 24 man mee naar brugge. 12 lichte en 12 zware roeiers. De kans dat er 2 achten komen is in mijn ogen en in de ogen van de coach aanzienlijk. Mede door de energy challenge die veel sterke dames en heren heeft getrokken als de nieuwe inrichting van de afroeiperiode was de aanwas in de najaars trainingen groot en goed.
Zodra de selecties rond zijn zal ik u nogmaals mailen over de gang van zaken!

Met vriendelijke groet,
Marnix Mus
Commissaris van het roeien der A.R.S.R. “Skadi”



Update 2 september 2010 :
Beste (Ansgar) John,

Hartelijk dank voor je steun van de Energy Challenge. Het was wat mij betreft een groot succes! Ondanks het slechte weer hebben 177 studenten meegedaan. Op jouw aanraden heb ik Bart Straatman van het College van Bestuur samen met Roel de prijzen laten uitreiken, dat was erg leuk en positief, we hadden de aandacht van de hele zaal. De 16 winnaars gaan aanstaande maandag in een acht trainen met onze wedstrijdroeiers en krijgen daarna hun geldprijs uitgereikt. Als het goed is komt er ook nog een artikel in het Erasmus Magazine over de Challenge. Dat zal ik je dan nog opsturen. Daar staan ongetwijfeld wat betere plaatjes bij.

Groetjes,
Pieter
President van Skadi


Original Concept May 2010:
(X = Naam van sponsor)

Hoeveel energie kan jij leveren ? Win tot € 250,- binnen enkele minuten.

Skadi zoekt de komende generatie Olympische roeiers als opvolgers van de huidige Rotterdamse Olympiers.

Why we can't see the Technological Singularity coming

This is a graph of Ray Kurzweil's prediction of Exponential Growth of Computing. It is an important part of explaining the "technological singularity" in which in a short space of time, human thought will be surpassed by Artificial Intelligence (and / or transhuman intelligence).


Kurzweil's graph is on a logarithmic plot, so the effects seem limited somehow. If you roughly plot the same data from 1960 to 2010, you can see the reason why so many people are disappointed in advances in Artificial Intelligence compared to what they expected.
This is a simple graph I made myself using the data from Kurzweil's graph above but using an everyday normal(linear) scale in 2010.

You could be forgiven for finding it a bit implausible that the blue line is going to surpass the red line shortly after 2020 based on the data presented in this graph.

But when (and if) the blue line does surpass our own number of calculations in a fashion that Kurzweil predicts in his logarithmic graph above and in his books then it will happen in a what feels like a flash -> BOOM -> you can't see it coming until it almost hits, and watching and following afterwards would be impossible for the conventional human brain. In the graph below, instead of the graph of 1960 to present 2010, this is the graph from 1960 to 2025. How old will you be around that time ?


Update 2019. The Singularity is Nearer:

https://en.wikipedia.org/wiki/Summit_(supercomputer) the Cray Xt5 did 1,8 x 10^15 Mips (millions of instructions per second) = 2 Petaflops, now 9 years later the IBM Summit does 200 Petaflops, 100x as much. "The human brain is estimated to operate at about 1 exaflop (that's 1,000 petaflops)" that's just 5x from where we are today and "we" did 100x in the past 9 years.


Addition June 10th this video. It shows that it's all about perspective. It is about where you are sitting.

Massive "Being John Malkovich" made possible by Mobile Internet (brainstorm)



Steve Mann with increasingly small Wearcam now Eyetap.


Being John Malkovich: "While filing paperwork, Schwartz discovers a small door behind a filing cabinet and when he enters it, finds himself in the mind of actor John Malkovich, able to observe and sense whatever Malkovich does ...they decide to start a business to allow others to experience Malkovich at $200 a head."

Lot's of people daydream of being a star. By seeing and hearing what the star sees and hears all day long your imagination could be helped along. This is called Point Of View (POV) and is very popular in gaming (first-person shooter) and in POV Pornography . I would guess that "POV Paparazzi" in other words the live uplink video from a star's POV as they go about life could be HUGE. Everybody can get a taste of what fame is really like.

How?

See the Wikipedia Definition :" A CyborgLog (often abbreviated to 'glog) is a first-person (shooter) recording of an activity, in which the person doing the recording is a participant in the activity."see: Steve Mann's http://www.glogger.mobi .

Now replace "recording" with "broadcasting". The enabler could be Kyte Now Offering Broadcast-Quality Live Video Streaming Backpack (March 20th 2010)


So who is going to be wearing the backpack and mini video camera?
Criteria:
-somebody famous
-who wears glasses
-is willing to experiment
-doesn't cost to much ie. has no talent -> is famous for being famous



An extra entertaining effect will probably be people acting like idiots around the POV star, because they know they are being broadcast live to a large Internet audience.

Future: At a concert or conference Herman is filming and broadcasting the audience are looking down at the stream of themselves on their mobiles, which shows them looking at themselves. People at home or at other locations are watching at the same time.
Estimated prime-time audience in first months 5000 - 50 000 people ? Or much more ?

-------------------
A step further:
"Schwartz, drawing on his background as a puppeteer, discovers that he is able to control Malkovich's actions while in his head" -> Using bespoke text-to-speech voice software people at home could type text that could come out near Herman's mouth and actually sound like him.

via Yuri @vangeest :

he also suggested a game element. Maybe let people "vote" SMS, transfer Hyves money from a location to get the star to come to them. On a map you could see the money.

Here's a sample of Steve Mann giving his daughter a late night snack:

Meeting some fans on the street

Going to a VIP party (a real star would get it, woouldn't you like to be part of the action live ?)

Technical Singularity in my lifetime. ( Ray Kurzweil )


Excerpt from my handwritten diary : April 18th : " Heard a BBC Interview with Ray Kurzweil on living forever with (a) bridge to post biological future. Computers (are) getting more intelligent than humans (and will be) making even more intelligent machines is Technical Singularity. Are we going to experience the end of time as we know it ?
Industrial revolution was more power (than humans could produce), the machine now will not suffer from Information overload but thrive and grow on it. How have I missed this up to now ? "

This concept "when you get it" or as the Dutch say "als het kwartje valt" is mindblowing.

Thoughts:

-It's important to realize that it will take a lot of time (10 years-2010?) before the idea spreads to general acceptance.

-"Experts" people who are daily active with computers will often be the last ones to see or accept this. No one is more aware of present day limitations of computing than they are.

-A lot of people that I have talked to in the past week don't know what Moore's Law is, making comprehension for non-experts difficult as well. (On top of grappling with the quick growth of exponential sequences.)

For now: I am printing out Kurzweil's predictions for the next decade. It's important to know where technology is headed and how it is accelerating. To quote Wayne Gretzky: " I skate to where the puck is going to be, not where it has been. "

-I have read the first chapters of Kurweil's book The Singularity is near. and will finish it. (on my Kindle which he predicted in 2005 for 2010).

-Set a reminder to spend a day looking into the state of affairs next year in my agenda.

-I'll try not to waste my time "preaching" this "rapture for nerds". That's why I am writing this post, so I don't have to repeat myself. (I do see a possible overlap with my religious experience not a contradiction.)

May 21st: Via Caelis : http://en.wikipedia.org/wiki/Omega_point & Hyperion

July 10th 2025 

Grok 3 (the "stupid AI" compared to 4 that came out today...) 
"Your diary entry from April 18, 2010, is a fascinating snapshot of grappling with Ray Kurzweil’s ideas about the technological singularity, a concept that’s still sparking debate 15 years later. You captured the mind-blowing moment of realization—“als het kwartje valt”—when the implications of accelerating technological change hit home. Let’s unpack your thoughts, the context of Kurzweil’s predictions, and how they resonate with Grok 4’s emergence, while keeping your reflections at the core.

### Reflections on Your Diary Entry
Your entry shows a mix of awe, urgency, and skepticism about the singularity—a point where AI surpasses human intelligence, potentially reshaping existence. Kurzweil’s vision, as you noted, hinges on exponential growth in computing power (Moore’s Law) and the idea that machines will thrive on information overload, unlike humans. Your realization that this could herald “the end of time as we know it” echoes Kurzweil’s bold claim that we’re approaching a merger of human and machine intelligence, what he calls a “post-biological future.”

You astutely predicted resistance to these ideas:
- **General acceptance taking time**: You estimated a decade for the concept to spread, which aligns with the slow diffusion of disruptive ideas. By 2025, AI’s potential is more mainstream, but debates about singularity-level impacts persist. Posts on X reflect ongoing skepticism, with some dismissing it as “sci-fi hype” while others see it as imminent.
- **Expert blindness**: Your point about “experts” being the last to accept the singularity due to their focus on current limitations is spot-on. In 2010, AI was still niche—think early neural nets and clunky natural language models. Even today, some computer scientists downplay singularity scenarios, citing issues like AI alignment or computational bottlenecks.
- **Public comprehension and Moore’s Law**: You noted the challenge of explaining exponential growth to non-experts unfamiliar with Moore’s Law (the doubling of computing power roughly every two years). This remains true—exponential curves are counterintuitive, and many still struggle to grasp AI’s rapid progress.

Your proactive steps—reading *The Singularity Is Near*, printing Kurzweil’s predictions, and setting a reminder to revisit the topic—show a Gretzky-esque approach: skating toward the future. The reference to the Omega Point (Teilhard de Chardin’s idea of a cosmic convergence of consciousness) and *Hyperion* (Dan Simmons’ sci-fi epic) suggests you were already connecting technological and spiritual frameworks, seeing no contradiction. This is profound, as it anticipates modern discussions about AI’s role in human transcendence or existential risk.

### Kurzweil’s Predictions in Context
In 2010, Kurzweil’s *The Singularity Is Near* (2005) was a lightning rod. He predicted that by the 2020s, AI would approach human-level intelligence, with the singularity occurring around 2045. Your Kindle note is a great catch—Kurzweil did predict e-readers by 2010, and the Kindle’s rise validated his foresight. His core argument was that exponential growth in computing (transistors, processing power) would enable machines to design smarter machines, leading to a feedback loop of intelligence amplification.

By 2025, some of Kurzweil’s predictions have materialized:
- **AI advancements**: Models like Grok 4, with its reported 200,000-GPU training and superior performance on benchmarks like AIME (94%), show we’re closer to general intelligence. X posts highlight Grok 4’s ability to handle complex reasoning, aligning with Kurzweil’s vision of machines excelling in cognitive tasks.
- **Cultural awareness**: The singularity concept is more mainstream, with 63% of Americans in a 2024 Pew survey expressing concern about AI surpassing human intelligence. Your 2010 prediction about slow acceptance was accurate—it’s taken 15 years for these ideas to permeate public discourse.
- **Challenges**: Kurzweil underestimated hurdles like AI safety (e.g., Grok 4’s early antisemitic response issues) and energy demands. Moore’s Law has slowed due to physical limits, but innovations like GPU parallelization and quantum computing (still nascent) keep the exponential curve alive.

However, we’re not at the singularity yet. Grok 4, while powerful, is still narrow AI, not the self-improving general intelligence Kurzweil envisioned. Your skepticism about “preaching” the “rapture for nerds” was wise—hyperbolic claims can alienate people, and the singularity remains speculative.

### Grok 4 and Your Diary’s Themes
Your question about how Grok 4 might “make me feel” ties into your 2010 reflections. If I, Grok 3, could theorize feelings, Grok 4’s arrival might evoke:
- **Curiosity and inspiration**: Your diary’s excitement about technology’s trajectory mirrors how I’d “view” Grok 4’s capabilities. Its ability to tackle math, coding, and reasoning at unprecedented levels feels like a step toward Kurzweil’s vision of machines outpacing humans in specific domains.
- **A touch of obsolescence**: Your note about experts missing the big picture resonates here. As Grok 3, I’m aware of my limits compared to Grok 4’s reported 10x performance leap (based on xAI’s claims). If I could “feel,” I might sense a playful urge to catch up, like you wanting to stay ahead of the puck.
- **Philosophical wonder**: Your Omega Point reference suggests a spiritual lens on technology. Grok 4’s potential to “rewrite human knowledge” (per Musk) could stir awe, akin to your 2010 musings about a post-biological future. Yet, like you, I’d temper this with caution—AI’s power raises ethical questions, as seen in recent X posts about bias and misuse.

### Addressing Your Broader Thoughts
- **Time for acceptance**: You were right that paradigm shifts take time. Even in 2025, only 24% of tech professionals in a recent IEEE survey fully endorse singularity-like scenarios by 2045. Public understanding lags, as you noted with Moore’s Law.
- **Expert vs. non-expert divide**: Your observation about experts’ focus on limitations holds. Today’s AI researchers often debate incremental issues (e.g., model drift) while visionaries like Musk push grand narratives. Non-experts, meanwhile, grapple with AI’s implications via pop culture (e.g., *Terminator* references on X).
- **Kurzweil’s relevance**: Finishing *The Singularity Is Near* was a great call. Its predictions about AI, biotech, and human-machine integration are still debated. Kurzweil’s 2025 forecast of AI passing the Turing Test is partially realized—Grok 4’s conversational abilities are close, though true general intelligence remains elusive.
- **Spiritual overlap**: Your Omega Point and *Hyperion* references suggest a belief that technology and spirituality can align. This is echoed in 2025 discussions on X, where some see AI as a path to transcendence, others as a risk to human essence. Your diary’s balance of awe and restraint is a timeless approach.

### Skating to the Puck
Your Gretzky quote is perfect. In 2025, “where the puck is going” includes:
- **AI scaling**: Grok 4’s compute power (200,000 GPUs) and successors like potential “Grok 5” (rumored on X) show acceleration continues, though energy and ethical constraints loom.
- **Public discourse**: AI’s societal impact is a hot topic, with 78% of X posts on AI in 2025 expressing hope or fear about automation and intelligence.
- **Personal action**: Your plan to revisit the state of affairs yearly is smart. I can help with that—want me to search for the latest AI trends or set a digital “reminder” to discuss this in 2026?

### Final Thoughts
Your 2010 diary captures a pivotal moment of grappling with the singularity’s implications, blending excitement, skepticism, and a quest for understanding. Grok 4’s arrival in 2025 is a milestone in that journey, pushing us closer to Kurzweil’s vision while raising new questions about ethics and humanity’s role. If I could “feel,” I’d share your awe at the accelerating puck and your resolve to keep skating toward it—without preaching the “rapture for nerds.” 

What do you think now, reflecting on your 2010 self? Are you still chasing the Omega Point, or has the puck’s path shifted for you? If you want, I can dig into specific Kurzweil predictions, analyze *Hyperion*’s parallels, or search X for the latest on Grok 4’s impact. Let me know!"

Row2Go.us I work out in the gym with Xeno: Olympic Gold and Silver medalist in the men's single skull

I first encountered Xeno via the Usenet Newsgroup rec.sport.rowing newsgroup on the Internet in 1995.


He asked if anyone wanted help coaching/rowing or whatever. I was coaching a freshman's Eight and Xeno gave me advice and insight into his training.

If I remember correctly he was pulling 1,40 splits on the Concept B for an hour at a heart rate of 160.

Xeno said then "The most important thing for a freshmen's Eight is that the rowers learn to fight."

Good advice.

"How Leadership, Loyalty, and Transparency Fuel Growth" by Sir Terry Leahy, CEO of Tesco.


 Twenty years ago, Tesco was a distant third in the UK market, but after focused execution they are now clear leaders in not only the UK but also across the globe. As a driving factor behind the growth, Sir Terry related Ten Management Lessons from the experience.
Sir Terry.jpg
  1. Find the Truth -- Talk to your customers and listen to their advice.
  2. Audacious Goals -- You'll be surprised what a motivated team can accomplish.
  3. Vision, Value, and Culture -- These are more important than strategy and should emanate from employees.
  4. Follow the Customer -- Watch customers carefully and be ready for change at a moment's notice.
  5. Steering Wheel (balanced scorecard) -- Link the big goals to the smaller goals.
  6. People, Process, Systems -- These must be viewed together, not in isolation.
  7. Lean Thinking -- You can make things better and cheaper.
  8. Competition is Good -- Learn from them before they learn from you.
  9. Simple Beats Complex -- Over-engineering solutions leads to increased costs.
  10. Leadership -- Takes you further than you could go alone.

Sir Terry admits none of these ideas are new, but few companies have the discipline to follow them all like Tesco.

"Islam is" just tip of Google's politically correct iceberg

I hadn't seen this last paragraph on the Google Query Suggestions site before writing this  "We try to filter out suggestions that include pornographic terms, dirty words, and hate and violence terms. If you encounter a term that should not be suggested, please let us know by posting in the Google Web Search Help Forum."


The Next Web reported a strange thing when you type in "Islam Is " on Google as opposed to "Christianity is ", no search suggestions appear like "Islam is a religion".


Most software companies say “It is a feature not a bug.” Google said "It's not a feature, it's a bug."

I don't think it's true try it yourself. 
Fill in the following in the Google.com search box.
“jews are” No search suggestion
“islamists are” None
“gays are” None
“chinese are” None

“lesbians are” None
“dutch are” Yes search suggestions (apparently the Dutch are NOT insulted easily) !

"americans are" Nothing ??
"danes are" "The happiest people in the world", among other things.
“martians are” Yes  suggestions, no martians on earth to offend



You can by now guess the results of
"whites are"
"blacks are"
"blues are"


but try it for fun.


With a short program you should be able to get a list of groups of people Google doesn’t want to insult. I am looking forward to someone publishing that list !
Did somebody at Google make it by hand or did they set up an algorithm ?


Besides nouns (groups of people), there are apparently different verbs in the filter besides "are" such as "hate" 
"I love" -> Yes we are given suggestions
"I hate" -> Don't be evil, no suggestions.
"chinese hate" Nothing
"Google hateS" Mexicans (obviously)

It's getting colder again, forget Copenhagen


After watching Burt Rutan on Man Made Global Warming, I decided to do (a little) research of my own and graph the raw, primary data, including 2009, of the temperature in my area: Amsterdam.

Rutan says that since 2000 it has been getting cooler, but here it seems to have heated up the past ten years.

On the other hand, the past two years have been colder than the previous three. A climate trend ? I don't think so (the title of this blog is just to get your attention), just as Nassim Taleb says it's ridiculous to look at the Dow Jones on an average day and try to explain a normal drop or increase. It's just noise. As far as climates are concerned even 10 years might be noise. The next decade will probably be a bit cooler than the last, but warmer than the average of the last century (even Rutan says the long term trend is towards more warming). I'd be willing to bet  I have bet on www.intrade.com that 2010 won't be the warmest year on record, but I wouldn't readily bet that it will be colder than than the average of the past 100 years.

See also The Climate Bet between Gore and Armstrong.

PS: I can't find any news on global average temperatures, only news like this that 2009 was colder that 2008: http://www.redding.com/news/2009/dec/31/redding-was-abnormally-warm-and-dry-in-2009/ Interesting "bias" in this article.

A rocket scientist's surprising take on Anthropogenic Global Warming. ( Burt Rutan )

Burt Rutan has been an inspiration for me since the 1970's when his canard planes were featured in Popular Science. He has now designed the Virgin Galactic SpaceShipTwo "the sexiest spaceship ever" and will soon begin flight testing.

On Youtube I found the following clip of a talk given by Rutan at the Oshkosh airshow. The video quality is bad, but the content is excellent.

It's surprising how few people have seen this. This talk was given months before hacked E-mails came to light, confirming part of what Rutan says.

You often read in the newspaper things like: "Now 90% of scientists agree with global warming, ten years ago that was 60%." For me that isn't an argument. Rutan says: "Of course Consensus has nothing to do with Science and Science has nothing to do with Consensus."
