Could we replace the sun with bulbs?

Answer 1

No, because the Sun provides more energy to us than bulbs could ever do. Bulbs give off heat, yes.. but it has to consume energy that WE have to make. Using coal and causing more global trouble and what not. The Sun is its own energy source... Besides think about it... How will you be able to supply ecosystems with light without destroying anything or building anything else... You see... how I think of it is like this...

If you have to light up a corn field... you're gonna have to build light poles.. and with light you need energy.. so electricals will be needed.. but how do we reach the poles when nature destroys it?... We go fix it with our big huge jeeps... you see... bulbs will cause us more harm than good.. it's good to light up homes and all... but not the world at the same time.

Plus.. the Sun's gravitational pull and it's light supports the very life on Earth.. without it we and our light bulbs don't exist

Answer 2

Yes you can. It is done in many greenhouses up north and in labs. Ordinary bulbs don´t give the right light though. The plants won´t grow naturally. The colors would have to be balanced to mimic sunlight.

On places like the moon it will be necessary for humans to grow their own food if we are to survive there but growing plants in direct sunlight isn´t an option. You can´t just put up a greenhouse. It would be far too costly to make it completely safe. Also the sun doesn´t shine for two weeks at a stretch. Replacing the sun with artificial lights is the only way. In an underground "garden" you grow plants directly in a nutrient sollution. This is called hydroponics. To power the lights you use electricity from photovoltaic cells mounted on the surface. You are then basically funneling the sunlight in by powerlines. During the two week long night you need to use electricity from another source. It might be some cleverly designed system of batteries charged when the sun was up or a small nuclear plant. Or just electricity from more photovoltaics from another part of the moon where the sun is shining.

And to those that say that the sun can´t be replaced because it generates so much more energy than we ever could: guess what we eat when we eat food? We eat oil. We use alot more energy in the form of oil when we grow our food than the plants actually photosynthesise from the sun. This is because of all the artificial fertilizers and pesticides we use. Not to mention getting the onions from friggin New Zeeland to your grocery store which might be as far from New Zeeland as two points can be on earth whitout leaving the planet... So we really could replace the sun. The suns energy is just one little ingredient to growing food the "industrialized" way. The increased cost wouldn´t be that big since alot of the cost of farming in the industrialized nations is covered by subsidaries anyway. This is called "unsustainable development". Guess what happens when we run out of oil in a few years time?

Answer 3

No. Not at all.
But remember that all of the fuel on the earth can light up the sun for 2 days 85 minutes and 52 seconds { seconds are in approximation}

Answer 4

well if one could invent a bulb which gives heat and light for everything to survive on this planet .but it is an impossible task

Answer 5

i m sorry to say bt u r illogical and impractical.......the nuclear reaction goes in sun is endless......and we are not able to perform that on earth.......hw do u suggest a thing that is impossible to perform on earh to set up at center if solar system....................well then it must be BULB SYSTEM.....lol

Answer 6

how many valley girls does it take to screw-up a light bulb question.

Answer 7

I think Koolaid is right. I like the name sakura. Did u get it from the card captor series ?.

Answer 8

No it cant be done no plug ins in space

Answer 9

no, we need the sun's gravity to keep our solar system in check.

Answer 10

Sure, if you can get the right wattage!
