Explore what would happen if we covered the Sahara Desert in solar panels, and the possibility of it solving our energy crisis. Stretching over roughly nine million square kilometers and with sands reaching temperatures of up to 80 Celsius, the Sahara Desert receives about 22 million terawatt hours of energy from the Sun every year. That s well over 100 times more energy than humanity consumes annually. So, could covering the desert with solar panels solve our energy problems? Dan Kwartler digs into the possibility

Instead of Solar Panels, which have to use wires to distribute electricity, my idea is to use Concave Mirrors, concentrate light, then transfer it in fiber optic cables around the world, to their location use. This would transfer energy without any loss, as well as you can convert light to electricity at the destination. For example, you can build huge concave mirror farms in Saudi Arabia, concentrate light, transfer it in fiber optic cables to India/China, and in a city in India/China, use light to heat boilers to produce electricity. This will ensure that, even if it's day/night in India/China (or any part of the world for that matter) you could still get electricity from the part of the earth that has a desert and day. So you can have 24hrs energy all over the world.
ANYWAY that's my idea, I don't know if it will work or not

They are horrible for the environment though. They are full of toxic chemicals that are mined by child labor and if the energy is stored, it is a story dangerous lithium batteries that are mined by child slaves as well. It s basically un-storable energy coming from a feel-good policy. It doesn t work. Dust plumes come from that desert As well that are essential to the rain forest in South America. The destruction of The desert could be catastrophic to the world ecosystem and the way it works. Also putting billions of dollars of an energy Plan into affect in a region that has been plagued with turmoil and corruption is never a good idea

What about subterranean heat pipe. If the sand is incredibly hot then why don t we collect the energy of the sand. So we could let the sand absorb the energy and probably do less destruction to the ecosystem.

cheapest power source we know - well, that's already clearly a lie.
Also, i didnt hear a mention of toxic byproducts that are generated by mass manufacturing and recycling of solar panels.

reply

And where and how do we collect and distribute the power? How would we transfer it around the world because obviously the desert doesn't need all that generated power.

meanwhile in libya where 3/4 of the country is a desert, we still have blackouts and depending on oil for electricity. we should be graded as 4th or 5th world country.

Props to both WhatIf (who made a video about this 2 years ago) and RealLifeLore (who made a video about this 3 months ago, but in detail. Nice animation though.

TED-Ed is like that one friend that asks questions that have nothing to do with our daily works but makes us curious as well for the answer.
reply

All good but the mirror power plant isn't the first of its kind, there are already several Concentrated Solar Power (CSP) plants that exist.
reply

government investment? i would love to see your data for that. i am quite sure government is doing everything to protect the oil markets.
