earth >?

Because 'weight' is not the same thing as mass. Mass depends on how much stuff you have (and stays the same no matter where you are) and weight depends on the gravitational constant where you are standing. Higher gravity (more massive body) and you'll weigh more. |

Earth houses are a great way Because the walls are made of
earth, and underground
temperatures are constant at
50-70 F, earth houses need
almost no energy to maintain
optimal indoor climate. Earth
houses also offer some
protection from harsh weather,
warfare and even crime. No
need to ever paint the
exterior -- or replace siding.
So why aren't all houses built
this way?

Well here is the dirt of it.. you really need to have a hill of some size so that you can dig back into it.. you can't just dig a hole and jump into it.. that would be a grave.. so instead of a grave you need a cave.. a big enough cave to build a house in.. and of course you need to re-inforce the roof of the cave or else it could become a big grave.. and since most hills are rocky, diging a cave is not something you can do with a pick and shovel..you can dig a grave with a pick and shovel..but a cave requires moving a lot of dirt.. and it ain't easy.. yes it is economical and helpful to the environment.. and perhaps more people should do it.. but when they get all the dirty details... they decide that it is more desirable to build a house on top of the ground than it is to go in a hole.. and thats just about the whole dirty explanation.. |
