A Solar Powered Earth


So how much land would be necessary to power the entire world with solar power...this much.

A clever guy named Matthias Loster has put together a map of the required surface area of the earth to produce the cheapest levitra online 18 terrawatts per year that our world currently consumes. From all the way out here, it looks like an amazingly small amount of space, and that's assuming just 8% efficiency.

Of course, good luck getting the trillions of dollars necessary to build such facilities... Nevertheless a fascinating way of sale viagra seeing our predicament.

of course, there's an intrinsic problem with a permanent solar facility in a desert: sand dunes will cover it

Transmission losses would be very high, for example the nearest solar source to follow link levitra online without prescription Europe, is Africa. Those cables will be singing. :)

The map is the best site how much cialis to show the total area required over the entire continent. Not that ONE HUGE facility should be plonked in those places.

There was a similar study done by Australia's CSIRO that said something similar for Australia. But no one in government takes "free" energy seriously as there's no commodity to mine and levitra endurance export.

Wrong solution..

A better solution is to have the devices we use require LESS power. Look at computers for a start. Bad power profiles and consume about 600 watts now!

Throwing more power at it wont solve the cheapest viagra prices canada core problem.

USE LESS.

of course we need to use less, but we also need to come up with alternate sources for the power we do use. I feel like one of the problems we have in achieving our green goals, is that no one can agree on what the absolute best way to do it is. . . . so instead of taking any action forward we debate ourselves to death.

It would have been nice if Loster’s analysis was a bit more extensive, but Paul’s response also leaves a bit to the imagination. Occam’s razor would help the surface wattage rating, and when I multiply even 28 watts by the number of square meters in a square mile, I get 72.5 million. I am not a scientist, however, and claim no expertise in such matters.

No one is suggesting that the photovoltaics be centralized. The map is an illustration, and if it is flawed, the matter should be taken up with the discount cialis canada author. Scientists do differ on matters such as this, but such issues are usually resolved empirically. I am glad to viagra costs see attention focused on our energy use and what to do about it.
