I thought some of you might find this useful.
There are ways to heat and cook using only the power of the sun - and really simple to do, as well.

Here's an adjustable parabolic mirror made of mylar:

These are all pretty cool methods. When I get a chance I'll be giving them a try. I expect great care should be taken when making and using such things.
I'd much rather have one of these:
I don't know. Some of those contraptions look rather unwieldy.
Honey, what's for dinner?
Baloney sandwiches.

As a former hunter, I think there should be a deer season for those who like to hunt with a parabolic death ray. It would be challenging and sportsmanlike. Give the deer a chance. But there would still be a general season for the old timers who prefer explosives.
There's nothing sporting about using technology to kill dumb animals.

There was actually a movement in some state years ago to adopt a spear only season. It was never adopted, and I always wondered if the movement was anything more than a political prank. It did make the news, although not as some major controversy, just as an entertaining news article.

I went along as back-up gunner for a guy who was hunting razorbacks with a bow and arrow. He had big round ones so I agreed to try to help him be alive at the end of the hunt. When he got his boar I complimented him on putting his bolt through an eye. He slowly sank to the ground, shaking visibly.
"I was aiming for his mouth."

Too bad Archimedes didn't have mylar - he could've won a sea battle single-handedly!

I admit, spears are still high tech, even cutting edge years ago.

Odysseus hunted wild boar with a spear as a young man, but the boar sometimes won. He could be identified by a scar one of the boars left in him.

There was a situation decades ago where, if I had had a spear, I would have dropped on a deer from a stand. I almost did it with an arrow (being 16 and rather crazy), but it didn't seem quite sufficient. I think with a spear, yes.
