Recent news in June 2008 that a Japanese firm has prototyped a car that runs on the reaction between metal hydride and water, did not cause joy in my heart. I was delighted to learn it was not really true. Like the rush to biofuels based on plants people eat, putting even small amounts of water into a car only bodes ill for the environment and human rights ahead. Meanwhile, climate change offers too much fresh water here, too little there, or too saline yet other there. Sorting out the public health/human rights of water from the ecological issues will be a stern challenge for politics at all levels of governance.
