Feng Jun glanced at Huangfu Wuxia and blinked. "Solar power can indeed generate electricity, but it isn't very stable... If there are ten-odd consecutive cloudy days and the battery reserves are insufficient, there'll be no electricity to use."
In the current Blue Star Realm, solar power generation was not particularly rare, but storage batteries were very expensive.
Feng Jun had never regarded solar power as a mainstream option. He only treated it as an optional supplement; the backbone grid was the priority.
Without a backbone grid to rely on, storing electricity in batteries would cost enough to make people cry, and that was assuming battery technology had improved substantially.
This was an extremely complicated issue. Even though energy-saving LED lights had become widely used, most urban streetlights still did not use solar panels. That alone explained a great deal.
But Huangfu Wuxia did not see it that way. "Can't electricity be stored the way spiritual energy is?"
That... that was beyond the syllabus! Feng Jun's mouth twitched. If she wanted to discuss battery costs, he could barely manage a conversation, but as for converting electricity into spiritual energy, not only humanities monks, but even science monks would be completely in the dark.
He did not know how to explain the matter, so he simply looked at her with disdain.
Huangfu Wuxia was a little too clever. Seeing his expression, she assumed she had asked an inappropriate question.
She promptly changed the subject. "All right. I came this time because I heard that your Task Management System has received excellent reviews from both Carefree Platform and the Pan Clan. I wanted to ask about it. Could you show it to me? My Tiantong Merchant Alliance is also interested in buying a set."
Feng Jun slapped his forehead. "Now that you mention
