Thoughts on a Possible New Invention

I just recently watched the documentary "The Island President", which is a film about carbon emissions in the atmosphere and the issues it has caused the environment, particularly coastal erosion in the Maldives and other small islands. This documentary really got me thinking about all the pollution that has been put into the atmosphere over the years and how much emphasis scientists and scholars around the globe have begun to focus on it, especially since the publication of Rachel Carson's book Silent Spring in 1962 (I just recently checked out a copy from the Jefferson Parish Library so they are currently out of stock if anyone was interested in reading it).
Anyhow, I have come to an understanding that, we as a community, and as a world really, need to continue to make strides to continue to prevent further damage to the Ozone layer from carbon emissions. One way I think this can be done is to find a more suitable fuel for our automobiles.
Now, we all know algal biofuels are being developed to possibly eradicate this longstanding issue, but I'm really not sold on this being an acceptable solution. Instead, I think scientists should work on developing a car that runs on phenolphthalein, a common base indicator used by chemists, and alchemists for that matter as well. After reading an essay by Saunders Overton and speaking to my neighbor, who is a retired chemist, I have come to the conclusion that this single invention could blaze a path for other inventions that would defeat carbon emissions and air pollution altogether.
