If I double the radius of a wind turbine, I increase the surface areas to collect wind by 400%.

The reality is that the cost to generate wind is inversely related to the size of the turbine. The history of wind energy and the market have come to a resounding conclusion: bigger is better, and bigger is cheaper. It was only with the advent of megawatt class turbines that grid parity was archived.

Current transmission of centrally generated energy accounts for less the 10% of the delivered cost of electricity, (Western Governors' Association 2006 Clean Energy Transmission Report) So the added cost of transmission is likely to be minimal.

Smaller wind turbines by virtue of their smaller radius are inherently less efficient in the use of the raw materials that make them up.

I agree with the comments of Mike Zagorsky above.

Furthermore, "distributive" power, as the author defines it, would compound the problem of intermittency associated with wind. If one has a large distribution network one can one can mitigate intermittency by having access to widely distributed resources--the weather is seldom unfavorable everywhere at one time.

As for putting small turbines in urban areas I think this is a very bad idea. If a turbine casts ice or loses a blade in the middle of a corn field no one is likely to be hurt, but such accidents in urban areas would increase injury rates and damage nearby property. Turbines do generate enough noise to be annoying up close and cast shadows that can be distracting--why would anyone want one near their home when they can be much more efficiently placed in rural areas. Finally, there just isn't a large amount of wind energy to be harnessed in the middle of populated areas. For efficient generation one needs widely separated turbines that are large and on elevated platforms.

James:

Given the claims that your making regarding your product, wouldn't make more sense to talk about the technology first and about the implications thereof second?

Our turinbe is not bladed and therefore the physics of swept area doesn't apply. Our verticle style is eligible for urban mounting because it doesn't make noise, isn't a threat to birds/bats, and doesn't vibrate. The point on distributed solutions is not Bill Gates' business model but rather that decentralized solutions have a tendency to drive centralized soluitions out of the market. Thirty years ago the mainframe was the future of computing because it was the cheapest and most reliable source of computer power - sound familiar? Having what you want, when you want it, and under your control is always superior to waiting on the utility, the government, the developer, and the transmission line to get finished.

These are all great, innovative and promising possibilities. So, let's tax carbon, level the playing field, fund renewable energy research, development and deployment and let the market sort out the best solutions. It will probably turn out to be a combination of many of the above. But nothing will happen with "drill 4 more" Bush in the White House and Republicans in charge of Congress.

Bill Gates's vision was only that software writers could make money just on that. So he bought DR-DOS, renamed it MS-DOS, tinkered with it and added some BASIC, and licensed it to IBM for their new personal computer, which they were scrambling to release after the popularity of the (pre-Macintosh) Apple PCs. The decision by IBM to license "clone" makers was what put a PC on every desk. Bill Gates' vision was to make money as an independent software writer from each unit sold.

In General wind energy will serve a specific part of our energy needs. In general if HVDC lines integrated with hydrogen distribution work out then look for the Great lakes states to become our major energy hub, and by reflection they will remain manufacturing hubs also.

The southwest can become a solar energy center, but we will need to engineer new ways to distribute water to make these area population hubs.
Solar power desalinization, and solar powered water pipelines (water) may be the answer here.
Solar and geothermal use for residential seems to be the best way forward, and in many ways this will act in opposition to the need for transmission lines and grids (especially if we can develop a reasonable way to store the suns energy locally (residence) for those times when the sun does not shine.

General Compression is working on a way to store wind energy to create a dispatchable renewable energy source. This has great promise, but in 20 years I will bet that solar with local storage in hydrogen or batteries will predominate. Large wind farms and solar farms will serve urban centers and manufacturing centers.

While agreeing that bigger is better, and that casting a blade in a built up area is dangerous, we should not assume that the traditional three blade design is the one for this case. In finland vertical axis turbines ( look a bit like a barbers pole) can be used in areas where wind is gusty and changes direction rapidly ( ie at the edge of forests and near buildings) and have different noise and safety characteristics. Relatively little r&d has gone into them but they remain a possibility so lets not write the possibility off yet.

It is worth remembering that electricity demand is distributed. Therefore PV and microwind being also distributed removes much of the tr6ansmission losses. There are quiet designs of micro wind energy converters. The problem usually is that residences and factories etc are usually not built in windy places. Nevertheless micro generation is to be encouraged because it is inherently a distributed source.

Large scale HVDC transmission grids have many benefits. The main ones are summarised here:http://www.trec-uk.org.uk/elec_eng/grid.htm .

It seems to me that in the long run a clever balance, between distributed wind power and large scale wind farms exploitation, must be established for wind energy capture for electrical energy production, taking into proper consideration all pertinent technical, economic, and socioenvironmental factors. In other words, I believe that there is no single & simple deterministic solution.

Obviously, there will always be more than one market. This new market is the local one where the consumers are themselves the producers, that for instance produces solar and wind energy in one town block and uses it in that same block with no cables or transmission costs. The traditional "long distance" generation market will still be required for factories where massive amounts of energy are used for manufacturing operations, especially in energy intensive industries like aluminium smelters and steel production.

Wind power needs to be linked to hydrogen production. That way a fuel cell can produce electricity when there is no wind, thus making the wind farm far more valuable.

Both utility-scale and distributed solutions will play important roles in the future of wind, solar and geothermal power. This is not an either/or question. There is room for all types of solutions. Not everyone will be able to afford or have space for on-site solutions, but those who can will lessen the demands on the grid to the benefit of all. The more we localize ALL of our needs - energy, food, work, etc. - the better off we will all be.
