"Polycrystalline silicon - Wikipedia, the free encyclopedia
polysilicon is energy intensive. to produce.
limited supply this last one I added to point out one drawback of solar."
This is a limiting factor to solar cells that use this Cristal.
It is energy intensive to make this said crystal this is why in same section I offered some alternative forms of the solar cell which do not necessarily rely on or use limited quantity of this crystal.
Please stop accusing me of being something I am "Not"
I am a conservationist that loves technology I just bought a "PS3"(immoral I know) to make my point.
Reason for buying it, is its lonely no one to hang out with and I been miserable with intellectual efforts to get people to change there destructive way and the fact I witnessed chem-trails this weekend.
I am just promoting caution to new technology and making sure it is not more destructive than the way we been doing it.
as far as biofuel and horses Said horse is not limited to Mono plant grazing where biofuel IS MONO CROPPED which IS DEVESTATING TO THE ENVIRONMENT AND HABITAT. This is the factor I am pointing out.
If a horse can graze so can wildlife. You put in a mono crop specific for fuel and you wipe habitat out which all other life can't live on.
This "Total cost" is higher in damage than the sq foot proposal you are pushing forward. regarding space.
Grazing land is used by many animals not just the animal for working.
I am in no way saying all or nothing I am focusing on "diversity"
Example of the all or nothing right now is the oil and coal industry it is too "mono" Thus are problems today as a result.
I was totally for solar and wind till I started to learn of the huge negative impact it was going to have on our ecosystem and limited resources. In some cases it was worse than just burning the fossil fuels.
But not all solar and wind is the same thus why some of the other links I pointed out that you made no mention of from your quoting me. such as:
