A 413 ft diameter turbine making a complete rotation in 5 seconds = blade tip speed of 177 mph. Seems fast enough to catch a bird.

413*pi = 1298 ft
1298/5 = 260 ft/sec
(260/88)*60 = 177 mph

Until a meaningful method of storage is developed wind will continue to be a waste of time and tax dollars. ~ Walt

There are many companies lately that claim new records on “the largest wind turbines in the world”, including our company Design Thinking Solutions RSA. We moved away from that competition, because for us it is not a competition at all. Our DTS HAWT constraint kite design allow us to approach 50 MW per wind turbine @ 12 m/s wind speed, and at +/- a third of the capital cost of a 10 MW HAWT intended to be produced by European Companies. The three bladed conventional design competitions may continue amongst those manufacturers, as they have got a long way to go. All fluid stream energy converters follows the mass scaling law m=k*P1.5, there is a size limit to economic implementation. Independent of the concept considered, the scaling laws hold. This is true for DTS as well, but the wind energy extraction architectures pursued at DTS offers the opportunity to drastically reduce the proportionality constant when compared with the “industry standard” three bladed turbines. In our case it also means that the financial returns look much better when compared with conventional three blade wind turbines. Payback is much quicker. More technical information from DTS will not really contribute to the aforementioned.

We also have an ocean current turbine capable of approaching 1000 MW per unit. The good thing about it is that it can produce a constant and large base load. The wind turbine designs are based on very low wind speeds in order to improve capacity factor, and be used in conjunction with hydro-electricity / pumping schemes storing / generating electricity as currently used, also in South Africa.

It will remain the task of all renewable converter designers and manufacturer’s to convince governments and investors alike, to consider alternative energy converters to coal and nuclear power plants by “thinking outside the box”. Our company achieved our first goal in designing the “game changing” large DTS wind and ocean current turbines. Our second goal to get these machines into the market place, is on the way.

With regards to nuclear power the following:

The dangers / fatal flaw of any nuclear plant lay in the fundamental requirements with respect to design and construction. These stringent requirements are mainly to prevent the accidental escape of harmful radiation and or nuclear fuel from the plant over many years. Therefore, during an accident or incident where something goes seriously wrong inside the nuclear part of the plant, it is impossible to know what is going on in the inside, and what will be an appropriate corrective action. This uncertainty to know what is wrong in an enclosed nuclear power plant (entrapped with the most powerful fuel on earth) is a fatal flaw in old, and will remain so in also newly designed nuclear power plants.

If the world politicians decide to drastically reduce the number of new nuclear power plants to be built in future, then the investors need to find alternative investment opportunities to consider.

Not the biggest , just the biggest allowed of the obsolete leonardo designs.The biggest is the horizontal Automatic feathering flat blade radial windmills that are subdued in corruption. this superior design works in 1000x,s more powerfull 24 7 currents and has no limits horizontally. the brainwashing programs work don,t they. you believe there is no other even when you see the 4 walls per rpm disappear and then close walls in unison.with far more power than a prop, the captured energy is unlimited verses a percentage yep brainwashing prevents even tests

Newtons Law that are basis of all natural Energy.That are now converted easily and now more powerful than all polluting others combined ,has to overcome corporate greed.that so far is in dominant positions. This is now under Nuclear Stress.

First self serving uninformed mistake , is assuming that props or vawts or other designs now used for the miscalculation of mans ability to convert natural winds and tides energy that are excessive , related to our foreseeable needs second mistake is to assume The low effectives power of todays windmills will remain dominant.

My Design is not mentioned ,It is by far larger, In fact at Half the height and 150 or whatever t wide it would turn at each end two of the largest Generators ever built simultaneousness These mass energy machines are 1000x,s more powerful in currents and thereby smaller to produce as needed energy by just adding Blades and cowling’s to increase vacuums on downward sides.and widths of the 4 walls per superior power revolution. Of course the issue is embedded corporations with other old well developed Ideas Not mass energy

The wind sceptics should note that Spain, which is a big counrty, now gets an average of 20% of its electricity from the wind ………….& the record for 24 hours last year was 40%.
And the new big mills have paid off their capital cost well before a new nuclear plant comes on line……………… ask the French!

Interestingly one of the contenders to build the 6 GW of new offshore mills planned in France ( yes thats 1000 of the big new 6000KW ones)
is “AREVA”….. who own all the nuclear power plants in France and Britain.
The contract is worth about 10 thousand million euros & they are much easier to build than nuclear reactors…………. and no nuclear meltdowns!

Britain has a similar plan to produce 25% of its electricity from windmills in the North Sea by 2025.

Anybody wishing to cash in on this bonanza should consider buying shares in Gamesa who have built many of the newer 2 MW windmills in the states… This Spanish manufacturer is currently nº 3 worldwide & has been investing all their profits in research and new manafacturing plants in the US, India, China & now Brasil.
The shares are currently down 80% on their pre crisis 30 euros+.
Their new 6MW Offshore model will undoubtedly get a good share of the upcoming Frech and British offshore market in partnership with Northrop Grumman (who are doing the bit that goes in the water).
Expect the shares to double over the next 12 months and then to double again the following year.

To the very first post who said that ‘nuclear fusion would require money to deal with the harmful waste products’….there are none. It’s just Helium.
