The Tankless Waterheater

I'm always interested in some new invention that runs better, cheaper or saves time. The new tankless water heaters are something else. They will save energy because you get hot water when you need it. Check out the following link if you think that you might want to consider one:

Our future is going to be a lot different and we are going to have to find ways to conserve energy and save money. It is a good policy for us to do, anyway. For sure, this present congress isn't going to help it's citizens. They are more interested in keeping us in debt to OPEK, no matter how much fuel oil we have. Wonder why we can buy oil from foreign markets that drill but we can't drill our own. Kinda looks like a double standard to me. If it is wrong here, why is it not wrong there? And, that's another story.
