What I really would like to see being developed and perfected NOW is a combined energy that would free people forever from heating and cooling their domiciles. Solar, I undestand, depends on the rays of the sun- but why not heat garnered from the heat of the day? Even in winter daytime brings heat.

We tend to think in terms of either/or but who says that is how it must be or that it is how it WILL be? How about something switching effortlessly and seamlessly between wind, sun and water?

If something like that were developed it would open vast areas of the world that are currently not survivable, climatically speaking.
