Would this work? Basically, greenhouse effect powers a giant wind turbine, harnessing lots of energy

>> No.969458

>>969451
Yes, it would.

>>969458
how come people don't implement such a thing then? what are the drawbacks?

Adding the inefficiency of a wind turbine to solar power?

BRILLIANT!

You wouldn't get much power out of it at all. You'd get better efficiency with solar sterling engines which are starting production.

I guess my thinking was just that the extreme heat caused by the greenhouse effect would result in very fast winds (making it more efficient than a simple PV system)

Thanks for clearing it up for me

Something similar to this is slated to be built in Australia. The base is actually quite huge, but its not made of glass.

it's not very efficient

Wow... that's work great if you made it absolutely massive. Maybe we could turn the Sahara into something useful.

The thing with the mirrors all focused at single core at the top of a tower is alot more efficient.

>> No.969660

according to the article, it is more wasteful (construction costs) than our existing methods

>In mid 2008, the Namibian government approved a proposal for the construction of a 400 MW solar chimney called the 'Greentower'. The tower is planned to be 1.5 km tall and 280 m in diameter, and the base will consist of a 37 km2 greenhouse in which cash crops can be grown.[28]

>Schlaich et al.[1] estimate a cost of electricity between 7 (for a 200 MW plant) and 21 (for a 5 MW plant) euro cents per kWh, but other estimates indicate that the electricity cannot possibly be cheaper than 25-35 cents per kWh.[41] Compare this to LECs of approximately 5 US cents per KWh for a 100 MW plant, wind or natural gas.

Hmm...

how can it be more wasteful than any coal power plant?

Wasteful is not the same thing as expensive.

My team had to design one of those in my eng1102 class. Inefficient as shit. Also, the tower has to be tall as heck. But, an inflatable chimney or a chimney-less design could be effective. They are cheap, dumb power.
