Solar is a scam. Every solar technology advancement turns out to be a lie. I'm willing to bet money that this technology will never actually work or if it does will cost 100x and be 1/100 as efficent as they say it will be. (reference: nano solar, or any solar company since the 70s) Commence the down voting.

If it's so obvious, can you at least link to some backup data?

sure just google 40% efficient solar, and then replace 40% with 50% 60% 70% 80% and then actually try to buy one.

So you're saying that wild claims on the Internet in a given field mean that that entire field is purely scammerific? You must have a difficult life.

Solar worked fine on my pocket calculator.

your pocket calculator uses solar technology that was invented 40-50 years ago, and my point is the technology hasn't advanced a lot since then.

Thanks. That sounds more reasonable than your original comment.

For most of us, paying $5 for a solar cell to replace a $0.50 battery in a calculator. However, that doesn't imply we can afford the same sort of tradeoff when real money is involved.
