We can and probably are trying that very thing, but the way plants do it creates sugars and fibers, not creating free electrons.

It's just not something that we can replicate completely for our purposes.

One thing we might be able to do is capture the carbon emissions from burning plant material, like sugars, then use the CO2 from those emissions to feed a new generation of photoelectric cells. There would probably be loses in the system, but...

Plants are significantly less efficient than solar panels, particularly because they are limited by the amount of CO2 that they can get. 400 PPM is a lot when it comes to climate change, but when you're trying to synthesize carbohydrates, that's a problem.

On top of that, photosynthesis only works in a narrow temperature range, it requires a lot of water that just gets evaporated, and it requires minerals and nitrogen, which have to be produced expending a lot of energy.

Right, the question is about the electrons generated by photo system 1 and photo system 2 during photosynthesis, and harnessing that as a means of electricity production. So by responding by saying photosynthesis doesn't generate energy, you're missing the fundamental aspect of the question in my opinion

But that's not what the question was asking about. The question was asking about utilizing the chemistry of photosynthesis for a new generation of photoelectric cells, which is both more efficient than burning fossil fuels as well as being better for the environment. This is an area of active and ongoing research, and shouldn't be dismissed by simply saying " burning fossil fuels is better"

Fixing a tooth is a minor surgery, not equivalent to just seeing a specialist. I'd compare it more to something like an MRI, which is comparable in price to putting a crown on a tooth.

Their prices are pretty similar after insurance; free to $30 or so for just a visit, and $500-1000 for a minor surgery or using a heavy-duty test.

Design and development of alternative logos and branding materials, including complete mock up of products, stores/restaurants, ads, etc. Focus groups, surveys, polling. Psychological studies, etc. When you're a multi-billion dollar brand with established worldwide recognition, you dot every I twice and cross every T three times when assessing any significant changes to your branding and image. Does it need to cost millions? Certainly not, but they're given a big budget and they're going to use all of it in case things don't go smoothly - those in charge of developing a new look want to be able to say they turned over every possible rock, explored every possible idea, etc.

You're only seeing the final product, not the work that goes into it. You might have graphics designers churn out a dozen or more different variations. Those logos need to be checked against any other existing trademarks. At some point, they also need to be tested in focus groups so that the average person can draw a link between the old logo and the new one; or if it's a new logo completely, ask if the logo makes enough of an impression for people to remember it later. There's research into whether the logo can be recognizable in all kinds of situations (e.g., what happens if you shrink it down to a 32x32 pixel square for social media? Etc.). Then there's all the regulatory and business hurdles of actually updating it.

Thank you for explaining this so succinctly. Would you please come with me to Congress to explain this to all the states bordering the Mississippi River so that we might begin to reduce the huge dead zone in the Gulf of Mexico when half the nation's fertilizer runs off into it?

>>Even just moving your mouse might be enough to determine if you're "real" as its actually quite difficult to simulate realistic movement.

A good way to show this is to open paint and then try and draw a straight line or a circle. It's not perfect. Now think about the equation or commands it would take to program a bot to draw that not-perfect line or circle.
