Hallu Iddavarige Kadale

I was adjusting the water temperature for the hand shower preparing for my bath. That is when I realized how apt the above adage was.
During summer, when there is ample sun and the solar energy gives really HOT water... we don't want it. But during winter, we crave for HOT water, which we rarely get.
I started wondering if there is a way we could save all the solar energy during summer to use it during winter/rainy season. What a bliss it would be to get HOT water when you really want it...
BTW, there are 4 variations of this adage, I want to share as I find them funny:
1. Hallu iddavarige Kadale Illa, Kadale iddavarige Hallu Illa
--- those who have teeth will not have groundnuts to eat; those who have groundnuts will not have teeth
2. Kudalu iddavarige Bachanige illa, Bachanige iddavarige kudalu illa
--- those who have hair will not have a comb; those with the comb will not have hair
3. Kelasa illade anubhava illa, anubhava illade kelasa illa
--- no work without experience - no experience without job
4. Hucchu bidade maduve illa - maduve aagade hucchu bidolla :P
--- last, but not the least "without marriage your lunacy will not be cured; without lunacy being cured you cannot get married
Do share if you have heard other variations ...
