The news:

Turning heat into usable energy seems to be a new idea but it has been the base of the solar panel creation and now we’re going back to the basics.
Hot asphalt might be the next big thing when it comes to alternative energy.
Why it’s important:
According to ecogeek.org:

Researchers in Massachusetts are working on a technique to turn heat gathered by asphalt into usable energy via water pipes.
This will be more like a big project but not really usable in smaller households unless huge investments are made, so it’s not really a rival to solar panels.
Heating water doesn’t seem such a big thing, I thing they should rather concentrate on using that heat and converting it into electricity.
