i need to vehicle build a bidge over a creek span between 28 and 32 ftWhat is the cheepest solution?
HEY Give us a little help hereWhere in this wide world are you? What are the soil conditions on the opposing creek banks? What are the elevations of the banks in relation to the highest level of the creek? What types of building materials are available? What labor force are you going to use? If this is a vehicular bridge, what size vehicles, hauling how much? etc Your best bet would probably be a concrete bridgeThis would require cranes, and skilled laborYou might also use a timber style bridge if wood is plentiful in your area If you have steep stable banks, elevated well above the creeks flood level: You could build a cable span bridge fairly cheaply Any way you go, you are going to spend enough money to justify hiring an engineerAn accurate survey, and soil analysis, would be helpful.
Theres plenty of renewable energy to be had out there we dont really need to use nuclear or fossil Wind and waveare the obvious but I also like the idea of geothermal energy
I agree with Northern all the wayEven more important The USA needs to do something quick which appears to be smart, or USA is likely to collapse economically and take most of the world into the collapse with usBuilding a HVDC high voltage direct current power line from West Texas to Tampa, Florida might be thought smart, as it could deliver electricity from the wind turbines in West Texas to the 15 million customers in FloridaWest Texas is the world's best wind corridor and it extends North all the way to CanadaWith the power lines, 22% of the USA electricity can come from the wind, with less rate increase than building nuclear power plantsHopefully, most of the nuclear plants have built in robots or waldos for replacing the rods which are not dangerous before they are installedWave, geothermal, and algae in transparent pipes, can each supply about 1% of our energy needs before they become terribly expensiveEvery little bit helps/ let's go for it Neil
Nuclear energy is far too dangerous to be messed with in my personal opinionIt's way too riskyI love the idea of wind energy, but too bad our government is retarded.
