I went through that articles, does anyone no what chemical processes it uses? Based on the laws of thermodynamics, it can't possibly do what it claims to do. Pulling the carbon atom out of the CO2 and leaving O2 behind takes a decent amount of energy, far more than they say that they use. They also said that the waste stays disolved in the water, meaning that there is waste and it is likely not just carbon in the water. Neither article said what chemical they are reacting with the CO2 to clean the air and what the 'waste' byproduct is.

Similiar units use about 50 kWr, this one claims to only use 500 W to opperate, meaning there must be a chemical reaction that it has to use to make up the power difference.

I don't believe either of the articles covers that point, but regarding the reasons for building rather than planting, I suspect the idea is that these trees purify much larger quantities of air than normal trees.

Also, you don't have to wait for them to grow.

Here is the bulk of the second article, it's tricky as there are unfamiliar technical terms but I'll try to decipher and translate them. If you access the link, there is automatic translation, it's not very good though:

Cool.

I doubt that it'll make Lima that much less cloudy though. That's climatic.

Just search for threads I've posted in!

Do you know how bizarre it sounds to hear about a robotic tree that cleans the air of carbon dioxide for someone living next to and appreciating a huge expanse of forest wilderness. I would prefer planting more trees.

Nah, not ready to move onto stalking posters yet thanks......I'll just keep doin my job...you let me know if you find a nasty thread you'd enjoy seeing me savaged in and I'll be there though...Give the posters what they want...

It is bizarre, but reasons are given as to why they are unable to plant in the city centre. Although there are parks and green areas in the centre, they must be insufficient to deal with the level of pollution.

Also the instant result is a plus. If I find anything further regarding the level of energy required to operate it, I will post.


DONKEY:

Would your opinion of Lima change if it weren't so polluted? Hmmm? Or were there other factors which caused you to dislike it?

It was a variety of factors. For one, I'm a country boy, I hate, hate, HATE the big city. Then I was just coming from a tiny tiny city in the mountains of central Mexico, where most of the streets were too narrow to even drive on, and the sun shone a lot.

The fact that it was cold the whole time I was there didn't help, and I missed the sun.

I think it's mostly the size and the absolutely dreadful state of public transport. At least Buenos Aires has amazing transportation.

Let's see... if you take the people of Lima and stick them in Buenos Aires... then we might have a city I could get used to. ;)

Where in Mexico? Taxco?

What's wrong with the combis in Lima...like Russian Roulette as I recall...pie derecho derecho...they shout and then push you out into the street without even stopping the bus...loved it.

There is little sun, for sure, because it is so overcast. But the people make up for that IMO as you said.
