You need to reread my post - I said nothing of the sort.

I read what you said and it is irrelevant. You said cheap energy is impossible due to the laws of physics. This is not a decided issue. Plants convert solar energy to a commercially usable form every day. And do it cheaply.

Solar electric panels may or may not be cost effective in the future. We have no ideas what breakthroughs might occur in materials and manufacture.

You have no way of judging whether artifical photosynthesis might become commercially viable.

I'm sure your opinion is reasoned, but it is not necessarily correct.
