Tesla releases patents

[bogan]

I don't think you do as it violates a basic engineering principle of taking the energy from point of release via extra channels to the place its needed. Its like have two gearboxes attached to a motor when one could do the job.
There is a huge amount of energy used and emmisions made from the start with companies design/build testing, political hot air/debate and then the transport/install/repair phases and new connection to grid etc.
These turbines are supposed to last 25-30 years but many of them are struggling to make 20 with many worn out after 15...
Wind power will be a good thing when its in a local package going to direct to the consumer, ie the small ones on lifestyle blocks/baches etc But it will never be that way as the govts/corporates lose a control mechanism over the people, they seriously don't want people making their own energy sources.
Wind power at the moment is like already owning a DR650 to ride to work on but buying an RS125 to use less petrol but leaving the DR650 running in the driveway incase its needed and also buying the RS125 on finance at say 30%. And then only using the RS125 for 50 out of 365 days of the years etc...

What a crock of shit. 2 gearboxes is still a lot more efficient than just lighting things on fire. Large wind turbines put in windy places get a lot more energy output per fabrication/maintenance investment than thousands of shitty little ones stuck in not very windy places. Electrical power distribution is actually pretty damn efficient.
Wind power is like buying an electric bike to reduce emissions on your commute, but keeping the DR for a weekend blat.

Did see an interesting story other day of a low level turbine that works on venture type effect and needs very little wind. Looks like it would be great for use on an individual household basis.

Seen a few things using this idea or proposing to. For a few years now venturi / helix turbines have supplied most of the power to a high rise in Chicago. Must have a look & see if they are still going. Very cheap, self regulating regardless of wind speed, very quiet & bugger all stress on them.
The same principle is being explored for tidal turbines & "kite farms". Tethered generators flown like kites.

no it isn't. have a look at pylons under heavy load vs off peak - that sag is energy lost as heat.
line losses are fucking insane.

V.A.W.T? i was hoping to have one by now. unfortunately its still in fucking straya. fucking strayans.

or, one liek


or
someone made one a few months back, but cant find pics of.

Wow, so you're telling me the backbone of the power distribution network generates enough waste heat to make some cable longer; omfg stop the presses, that must be almost 3% energy wasted

Those HV lines sure get hot alright

[Akzle]

according to nemo, (i'm far too lazy to investigate this for you) 6-8% is considered normal. which worked out to be a mere 20 billion dollars a year wasted to warm up the lines, and the atmosphere.

oh, except they didn't waste it, they just made the consumer pay for it.
but fuckyeah, good system for sure, this centralised power shit. gews are fucking loving it.

touch one.... g'wan...

I think you'll find the 6-8% includes transformer losses etc as well. Regardless, where they put the wind turbines now is more than 6-8% more windy than on top of your shack so we're more than compensated for grid losses.

Can't be two bad as birds sit on them.

according to wikipedia (which is >90% bullshit) the line losses were 7.3% in 2011 (guess i can be bothered after all)

i maintain that centralisation is fucking stupid.

In the interests of sustainable resource management I suggest you resort to collecting it in a bucket.

Or even greener: don't buy any at all. Grow your own.
