replace giant metal fan blade with a canvas sail like on an old pirate ship take it or leave it

sometimes the wind blows at night.

the issue is not efficiency, it's the amount of energy it can produce relative to the cost.

object.property :
if you're inefficient with wind capture, a bit more wind gets through, if you're inefficient with fuel energy capture, you end up making too much co2

it's even crazier when you hear about the Betz's Law. essentially wind turbines can't be more than 59.3% efficient.

multi billion?

So basically we are at 50 percent of the Betz law

Taking your analogy further the hybrid rolling down a hill: if you don’t fully stop the car it will roll “forever” and keep generating electricity.

Wind mills take very little space, we install them in ppl’s farms and lands, for PV we need low grade land. Plus you can stop a mills easily.

It's fantastic compared to the AVG solar panel.

not use pv cells because wind energy is like a way of converting all the area on the planet without pv cells into "solar panels" generating wind

wave power and tidal power is the way

they're still the lowest carbon to KW ratio producer, and largely recyclable. solar panels which are about 1/3rd the carbon of coal and non recyclable

There is more wind than sun at night

Cost more to operate than it produces and damaging to the environment via the massive amount of oil it needs and birds it kills

you know we coouuld have H2O powered engines but nooo people just end up dying..

Line the turbine blades with flexible solar panels. Problem solved 😂

they should build the blades way different

Well you see most of the time a wind turbine will break down and be decommissioned as soon as it’s paid off so there is no real money involved in them

Constantine :
The limit is exactly 16/27. The equation to find it is super satisfying too. I’d write it out in here but the formatting would be horrible

William McClanahan :
so would you say it's actually like ~40% efficient because it's 25% out of 59% total

ŦΉΣ ЯΣΛPΣЯ™ :
I said 20%

because PV cells don't work when it's cloudy

Seran :
"Multibillion turbine" is misleading. RnD is multibillion but spread over huge amount of turbines that have much smaller production cost per turbine

violetglove :
so the wind turbine is producing 1 joule per 3 burned joules of fuel and everything else goes to the wind fan? 😳

Hybrid gas electric should have been the coupler to EV only. Trains are the most efficient systems. Trains have been doing it for decades.

The interesting comparisons would be the effeicieny per KG of rare earth metals in PV vs Wind Turbines, per kWH produced.

How many solar panels would it take to make 12 MW?

there are places that have very low sunlight but due to that high average wind speed.

So it's the same as solar

here for the memes :
what about the ones that are like a sleeve and basically shake/vibrate to create electricity

The thing about only using PV cells is typically when it’s sunny it’s not windy and when it’s windy it’s typically cloudy

Who gives a shit if its “inefficient.” Its making energy for free

A modern PWR nuclear reactor has an effiency of 30-35%.

Mechanical efficiency is nowhere near as important as cost efficiency. The first is an engineering exercise the second economics. Guess which dictates

How can something so ugly cost so much and do so little

gauravphatnani :
The thing you described is not efficiency. For example, if incoming wind has velocity of 10mph and, and wind outgoing from turbine is at 2mph. (1/2)

what about shockley queisser limit
2023-07-28 20:09:07

G :
so it's like more like 42% of the theoretical limit, and PVs don't capture all solar energy, such as thermal, pv + thermal + wind for the win.
