there still is a downside to hydrogen fuel car exaust. that increase of humidity can cause a serious imbalance in the natural environment of that area. thta is what happened in Phonenix. for about 4 years in a row, home built in pool sales had skyrocketed, but during the summer months, the polution inVersion layer increased a lot also. they brought in environments specialists to analyse the problem, and the pools is what they came up with as their responce. the city began making more laws regarding pool ownership, installed more restriction on new ones, and 'asked" the public to slow down a bit.

This was when I was there, about 8yrs? ago. i am sure it would not be too hard to find the actual reports if one was inclined to do the search.

The Phoenix area used to be heavily irrigated for farming. I'm sure they had atmosphere inVersion layers back then also. I guess they just called it a fog or a mist instead of a pollution inVersion layer, because they didn't have much automobile pollution.
I'm all for a gentle clean morning mist that will drop the daytime highs below 120f.

(ok below 100)

Well said...
I'd like to add that the weight of the emission equipment is important in a moving vehicle. Moving this weight around adds the the combustion vehicles inefficency and results in more fuel burned.
A fixed location for emissions controls makes the weight a mute consideration. It also opens an opportunity for better controls.

Well, I've checked this thread a coupla' times today and a few people mentioned stuff about 'big oil'. I've been thinking that Bush's whole idea was not for a hydrogen car but a political decoy. Everyone knows Bush is 'big oil's friend. I just think it's a ploy - let's wait 'till someone gets the money and does some measurable research....

Well, Earth's atmosphere is mostly nitrogen, so if you use a regular air intake to mix in with the hydrogen in the combustion chamber some of it's going to combine with nitrogen.

Still useful, though.

I wasn't saying you could drink the water from gas powered cars tail pipe.

Pity. In space they use the hydrogen fuel cells to provide hot water! No tail-pipe on the I.S.S. I suppose...

Microwave beams do sound cool, except that if the satellite slips out of it's geosynchronous orbit it could accidentally frazzle anything on the ground below it...

If the area the beam is sending the energy to is concentrated as well.

One of the costs of solar power that isn't usually mentioned is pollution from manufacturing all those solar panels. Making photovoltaic cells is a pretty nasty process, from what I've heard.

I heard that some people in Japan are putting solar cells on top of their houses. They have to buy them, maintain them, and they have to pay the local electric company more than the going rate for this electricity, and sell their surplus electricity back at less than the electric company's going rate.

This is mind boggling. Why do this? Prestiege? To benefit the rest of the neighborhood? To just insure they personally are never affected by a rolling blackout?

And if the Last one is true, is that a good enough reason for parts of the US to do the same?

Oh no, a chink in my capitalist armor. Quick someone plug it with a wad of 20's.

dude, Japan could teach the course on capitalism. sure, they over extended their economy a bit by purchasing half of the developed world, but they're getting better. slowly.

and if making the little guy buy solar pannels in order to profit off of them isnt capitalism, im not sure what is. I just wish I'd thought of it (and been in the position to benefit from it) first!

Of course, all the excessive industrial polution in the world will eventually reap disasterous results. Like giant lizards emerging from the waters off shore of Tokyo. You know, "Time shows us again and again, how nature points out the folly of man."

GO-GO-GODZILLA!
