We have had the technology to replace fossil fuels for decades.
The world economy is, in large part, based on OIL.
So, we need to force our governments to make this happen. It's all about the bottom line, not about technology needing to advance.
Yeru, this thread is a good idea. You are telling us important information.
We need to learn about these things, to know that there are viable alternatives available NOW to fossil fuels so that we, as individuals, can start turning the screws on our governments. Let them know we want change, now, not decades from now when the problem is so much worse.
