I want to solar power a 4x8 sign. What do I need to do?

We Answered:

one solar panel, that will put out 45 watts [d/c] will run you around $359.00
if you have 110 volt bulbs you will have to have a inverter, and a storage battery,
the cost will be out of sight,

Garden Pond Question - Is there a way to solar power my filter?

We Answered:

I don't know of any need for a powered filter... usually, as far as I know, the pump pushes the water thru the filter... so if it's strong enuff, the water moves thru ..... a bio-filter is the usual way for solar pumps.... here's a site with 'stuff'...

as you look all this over, you may find that the cost of the equipment makes having electrical hookups relevant.... and a whole lot simpler.....

Tracy Said:

what material is best suited for the stem of a solar power tower?

We Answered:

Too vague, there are many materials that could be used.

You need to know the height, weight of the tower, and what the wind forces are. Then you decide on the shape and size of the base. You will need a dollar budget. Then you can (if you are a structural engineer) design the structure.

Is Solar Power the best option to stop Global Warming?

We Answered:

Solar power is the best long term concept to reduce global warming/CO2 emissions. Ultimately all renewable energy (minus geothermal) comes from the sun's energy. Following nature's concepts of sustainability is one of the keys to having a sustainable energy system. Wind power is a good idea and necessary, but it will not be enough, because it has too large of a footprint to be our energy staple.
