I have to admit, not a bad concept for a sci-fi movie, but with our current technology if the carbon from current emissions isn't bad enough, the carbon released from all those rockets would be disastrous! LOL (That is, if RP-1 is used as the propellant)
Not to mention the weight of the water
However----water fuel, if it ever comes to be? Hmmm
Hoped some would see the humor, we want to save the planet, but we also don't mind do considerably more harm in the process. 'We have to act now, tomorrow is to late...', but what are the consequences of these actions?
Cash-for Clunkers, a program to take gas hungry, inefficient vehicles off the road, and replace them with pretty, shiny, new, only slightly improved cars. The 'clunkers' were engine-disabled, so those of us who can't afford a shiny new car, and the $20-$30,000 debt, couldn't upgrade to a slightly better clunker. Most of the trade-ins were much better than my '91 Explorer, since $4,500 was mostly a down payment. A lot of people got new cars, many will get repossessed, and good luck to them finding a better clunker, than what they traded in. The trade-ins will be crushed and shipped to Japan, who will melt them down, burning coal, to manufacture more cars.
Regulating carbon emissions is a fine dream also, but the add-ons, and upgrades are going to increase emissions, least for a while. Recycling the old parts and materials, is going to increase emissions. The demolition, transportation, and reconstruction of new plants, is going to really increase emissions. And since this all will increase the CO2 levels considerably, won't we be force to put out stronger restrictions? Process repeats, nothing gained. It's pointless to tear down something the still works fairly well, to replace it with something only slightly better.
Developing countries building power plants. Burning stuff is usually the cheapest way to get started, the US doesn't allow most countries to mess with nuclear stuff, renewable technology is very expensive on a large scale. Seems like us actually going on site, and building the power plants green, would be better than writing a check for a couple of billion, and hope some it actually gets used as intended. If you can only afford to build a few coal-burning plants, and you get enough money to build a few green plants, or dozens more coal burners...
