Bi

ography of Dr. Chul Park

Chul Park recently retired from the NASA Ames Research Center, where he worked as

a Staff Scientist in the Reacting Flow Environments Branch (formerly the

._ Aerothermodynamics Branch). He joined Ames Research Center in 1964, beginning

with a three year position as a National Research Council Post-Doctoral Research

Associate. His pioneering works include conception and design of aeroassisted transfer

vehicles, for which he holds a patent, study of radiation and radiative transport in air

not in thermodynamic equilibrium, environmental impact of the Space Shuttle on the

ozone layer, and an impact of meteor penetration of the Earth's atmosphere. He is the

author of a book entitled Nonequilibrium Aerothermodynamics, and authored or coauthored

over 180 articles and reports in scientific conferences and journals. Chul Park

received a B.S. (1957) and M.S. (1960) in Aeronautical Engineering from Seoul

University, Seoul, Korea, served briefly as an Instructor of Aeronautics at the Korean

Air Force Academy, Seoul, Korea

, and received his Ph.D. (1964) in Aeronautics

(hypersonics) from Imperial College of Science and Technology

, London, England. He

is currently a Professor on the Faculty of Engineering in the Department

We here do not yet have note regarding his biography during the last 16 years; we hope others and Professor PARK Chul will supply.    

 

Harry:
Thanks for spreading the word.
The company you mention has had the same experience of other underwater turbines such as the one in the Hudson River: The blades broke.

Yes Superturbine(R) technology potentially solves that problem by using many smaller blades instead of one big set. Result: Lower total rotor mass for the same total swept area, and higher RPM which reduces the need for gearing.

I feel as though we are looking at the answer to the energy crisis if only anyone could believe it could be so simple.
I wish all the large deep pockets organizations that purport urgency in developing clean energy could take a moment to realize they need to get proactive and identify such breakthrough technologies and nurture them. Instead they continue to place the same gauntlet of way too much paperwork into the path of us innovators, rather than identifying us and helping to move the breakthrough technology forward. The actions do not bring about the stated goals, but instead just more of the same. They are like an alcoholic who needs "just one more drink" to get back to "normal" so he can drive him self to rehab. They can't understand doing anything they're not already used to. The president specifically states that we need to identify and empower all the small-time innovators out there whom he knows have the solutions, yet the status quo bureaucrats are habituated to considering only the established recognized brand names with familiar designs, whose technology is too far committed through tooling and even tradition at this point to change or be replaced by them: an o0cean liner can't turn on a dime when it is at full speed already - it can hardly turn at all but is just going to plow ahead. So it's up to us to build it and get it out there, and we can't afford to wait for help from on high.

Well if you believe every press release, there could be no energy crisis. I mean every week someone announces a new (old) wind turbine idea that is somehow 3-4 times as efficient.

Let's be sure to look to any embedded lessons that might
affect "AWEifications"  of anyone's turbine. For example,
how might we "AWEify" the Honeywell direction, or the
China maglev direction, or the double-vortex mixing
direction, or the high-count multi-rotor SuperTurbine (R)
direct. Get these babies sized and tethered into higher
winds?   Spacecannon?  Fred Ferguson?  KiteLab? SoarEn?

Honeywell has become the assignee of some large AWECS
patent concepts; they are not going to just sit on rooftops.

• Terms evolve as assets blossom. Terms often are not static. Terrain involves AWE in very many ways.
• Anchoring
• Transporation of assemblies
• Boundary layer of wind effects

• Altitude of terrain for operating AWECS
• Specialized terrain formations that allow choices:
• Installation of base station for launching
• Installation of flexible cable for holding working wings and kites
• Use of regular wind venturi events

• Terrain may allow launching AWECS into higher altitude winds while using less tether or bringing
  less challenges to people and property.
• Terrain may allow hanging flexible cable on which to hang horizontally or verticall various working wings.

DaveS    proposes for our consideration: 
"Disambiguation: Prior Terrain Enabled Wind Power (TEWP) usage is preferred
over later Terrain Enhanced Wind Power. Proposing Terrain Enhanced Wind Resource (TEWR) to replace confusing TEWP usage." ds

Discussion is open:
Perhaps there some distinctions to be made, so assets won't be lost.
Perhaps there is more to this than just a couple of distinctions.
The wind is shaped in many ways by terrain formations.
Terrain formations allow different sorts of activity.  There is terrain receiving less-disturbed airs off bodies of water.
There is terrain as mountains that may allow varied sorts of AWECS instatllations.
Terrain in combination with manmade structures.
Compositon of terrain affects anchoring costs and methods.
Valleys, gorges, plains, high and low terrains, islands, multiple islands, open sea, seabeds, etc.
Examples for classification will probably be examined to sort out distinction on whether the wind resource,
ground-operation parameters, or  flying parts are affected by the nature and options of the terrain.

Terrain challenges, terrain opportunities, terrain as parameter, terrain as resource, terrain as friend, terrain as foe,
terrain as enabler, terrain as enhancer, terrain as former, cost of use of particular terrains, remoteness of terrain,
available terrain, off-limits terrain, instabilities of some terrains, terrains on the move,  
moving terrain by AWECS as a means of storing AWECS-gained energy, holes in terrain utilized for AWECS operations,
deliberate terrain forming for enhacing or enabling effective AWECS installations, ...?..., etc.

 

 

 

 

 

 

 

Partly, this is a test of this Yahoo program.

AWE Superstore is a collaboration. We are lising the Pocket Aviation (tm) first item in one of the

several departments.  Department:  Kites, kytoons, aerostats, pilot kites, lifters,

The aim is to link to others' independent web pages. A modest skeletal beginning

with much room for growth invites all comers. Departments are availble for full AWECS systems, services, consultation, etc.

The the single product (exampling) is here noted when one clicks Pocket Aviation in the preamble page:

 

Pocket Aviation™ As recently posted to the AWE list, a small kite on fine line can reach fairly high altitude. At little risk or cost the upper surface boundary wind resource can be directly sampled. KiteLab, Ilwaco, WA, has assembled a quality system around a modified* Gomberg Pocket Sled and 300 m of added fine Spectra fishing line on a plastic winder, all stuffed in a small mesh pouch that fits a shirt-pocket. An included mini-carabiner and nylon-ribbon-strap lanyard allows anchoring to all kinds of objects. The kite easily reaches about 700 ft altitude (with the usual strict precautions!). This is an astounding aviation capability in a pocket format for $30 USD. * The modification replaces the double tail with a Y-bridle and a single tail. It is lighter and more stable. Shipping is from Washington State, USA, paid by buyer. Washington state sales taxes are included in the net price.  Order is managed by AWE Superstore as a bridge to KiteLab, Ilwaco, WA.

Part of this test is that button.

In all cases, welcome to a point in history of AWECS.      Be sure in time that your offerings are listed in AWE Superstore.

Rugged terrain will usually involve more expense to tie in to the grid, both for distance  and construction cost.  Remember the years that the Altamont wind turbines were just for show, lacking a power line?

Bob Stuart

Bob,   Good point. We see how magic it might be to prospect for ideal set-ups where wind, terrain, populations, undersupply, & grids come together.   A golden baseload opprtunity might be, say, a declining coal plant in a river valley with great valley winds. We hang cheapo WP off of terrain on steel cables & drive existing generators in place (by ~direct cableway or via steam cycle), to serve an existing grid. Burn coal as before, *sigh*, but only in calm. Its new renewable baseload capacity at the lowest capital cost.   There is as yet no competition for such not-so-rare but uniquely promising TEWP sites.   daveS

Draft:

Proposed for discussion with aim for eventual industry-wide consensus:

AWECS tug, grind, saw, move, push, pull. generate electricity, etc. AWECS will be operating in very tiny environments (e.g., providing energy for sensors inside living creatures) and very huge environments (e.g. massive meshes mining jet streams or tidal flows).  AWECS will convert fluid flow kinetic energy to mechanical energy which in turn could be directed  to do next-step tasks. What could be the names for power levels? And what would be the power ranges?    Given: One watt  is equal to 1 joule (J) of energy per second. 

Teasing start:

      = Micro Energy Products ( 0+ up to ??W)
      = Mini Energy Products (?? W to ?? W)
      = Small Scale Energy Products (?? W to ?? kW)
      = Medium Scale Energy Products (?? kW to ?? MW)
      = Large Scale Energy Systems (above ?? MW)

What power levels and names for the level?   

What say you?

Wind power is already economic using ground-based beam-type structures.   Kites, being primarily tension structures, should be able to economically harness lighter winds.  It may be tempting to chase the fastest wind spots, but I think that the more importanat factors are consistency,  proximity to the  grid, and proximity to  opportunity for pumped hydro storage.

AWECs list members,

As you may know, I am no longer subscribed to the AWECs list. However, I would like to extend an invitation to the entire list to attend the North American Buggy Expo (NABX) on Ivanpah Dry Lake bed on the California/Nevada border this March 30 - April 4. I am not affiliated with NABX in any way and derive no financial or other benefit from their event--I go because I enjoy it!

NABX is the United State's pre-eminent kite buggying event. It's been held on this site annually for more than 15 years and will feature upwards of 300 participants; drawn to California's high desert to enjoy mild Summer-like days, crisp nights and premier kite sailing winds from zephyrs to 40 mph howlers.

Not an alternative energy event, rather NABX attracts some of the most skilled kite designers and kite flyers in the world. This year New Zealanders Peter Lynn and Pete Lynn; arguably two of the world's best traction kite designers and manufacturers will both be there, competing against Europe's and America's best designers and kites. Professional, semi-professional and rank amateur kite buggiers from all across the United States, Canada and even from France, the Netherlands and Germany (and New Zealand!) will be there. There will be spirited racing, and also a great deal of fun as the "pros" let their hair down and just have a good time kite buggying amongst their friends and rivals. There will be attempts against the world kite buggy speed record--currently near 75 mph. There will be beer, spirits (shared with friends--never for sale!) and "shot car" racing galore.

Ivanpah Dry Lake is a 15 mile-long by 3 mile-wide dead flat, dead smooth dry lake; clay surfaced and reserved, for all time, strictly for wind and human-powered vehicles. The world record for land speed sailing was broken there in 1993--and again just last year--during NABX! The lakebed straddles the state line between California and Nevada; HIghway 15 (the main highway between Los Angeles and Las Vegas) bisects the lake, and of course there are several casino/hotels--right on the lake shore. You can stay in sartorial splendor at the casinos for $30-40/night, or you are welcome to camp on the lakebed itself. There is a huge discount "outlet" mall within walking distance of the casinos, so even your "better halves" can enjoy themselves.

Please, I invite you to go to www.nabx.net and check the event out. Tickets are $75 for participants (buggiers) and $45 for non-buggying guests, and are good for all 6 days of the event. Your ticket will likely include some meals, a commemorative T-shirt, insurance coverage and a lifetime of great memories. Many participants drive there from all over the US, or discount flights are available via Las Vegas'  International Airport--just 40 miles away--with inexpensive rental cars available.

If you've ever wanted to learn and "feel" the state of the art in traction kiting--this is the event to make. Please, won't you join us?

Respectfully,

Dave Culp

Perhaps someone will have a heavy buggy with the wheels cranking onboard
generator

to charge a significant set of batteries. Light up the buggy for
evening runs via traction-gained

electric generation. Get from A to B in cycles while ending up really
charged! Buggied AWEgen.

Thanks for invitation!

The prevailing direction of winds such as the westerlies in both hemispheres blowing from the west toward the east suggests something about the boundary layer between the earth and the atmosphere. The sense of the earth's rotation has the sun rising in the east and setting in the west. The Jet Stream follows the same path as the westerlies.
 
Evidently not all wind energy is caused by uneven heating of earth and ocean. The westerlies and the jet stream may result of the interplay between the effect of the boundary layer between earth and atmosphere combined with the effect of solar gravitation on the earth's atmosphere.
 
 
This interplay certainly provides some good prospects for superwinds.

Not using Hotmail on your phone? Why not? Get it now.

It is easy to see the effect of extraterrestrial gravitation on the ocean, and the moon is a much stronger influence than the sun.

Bob-

The westerlies blow closer to the poles and outside of the tropics where gravitational influence of the moon and/or sun is less than inside the tropics. where the SE trade winds generally blow.
 
Interesting prospecting for wind.

Will AWECS installations have less land use per watt than hard-towered turbines?

The site cannot be used  safely for slope soaring by hang gliders.

May AWECS become known as having good manners.

 

Hi Joe,
 
 
The spectacle of wind turbines in the links you provided remind me of the kind of logging that prevailed on public lands in Western Canada, in parts of Indonesia, Brazil and Central Africa. The sad part about tower-based wind turbines is that most of them operate courtesy of government subsidy. Lets hope that AWE can operate free from government subsidy and with less impact on the land.

side than at the ground side. Am I correct?

Cheers, Theo Schmidt

The weight of a longer line will definately impose greater tensile stress along the entire line. The upper section of line will carry the added weight of the airborne lower section of line. Perhaps adding some lightweight material such as kevlar or carbon fibre nanotube into the upper section of line may alleviate part of the problem of added tensile stress.

I think you are right: the line's weight will cause the upper part to
carry more of the weight, but the wind drag will be carried more by
the lower part. (The line will curve like a parabola, with the upper
part more vertical and the lower part more horizontal. Since the wind
drag is the horizontal force component, all the wind drag will be seen
at the bottom of the line with zero (or negative) horizontal force
seen by the upper point of the line )

Maybe these two forces will be similar resulting in a more or less
uniform force throughout the line?

My feeling from flying single line kites at large angles to the side
of the wind is that the wind drag will be much more than the weight,
so I believe the lower part of the line will have to be stronger. Only
exception would be a very heavy streamlined tether.
