Ask someone who runs a grow room using CO2 to boost the air mixture inside the room. You get a higher yield, yes. Oxygen production however will not increase enough to make it safe to be in there without a respirator!
People who own hybrids or electric cars try to show by analysis that they are saving money, but usually they are not!
1. Consider the depreciation expense. A Prius depreciates at a higher rate than a Yaris. The depreciation of a Prius in the first five years is TWICE the depreciation of a Yaris, or about $6,000 more. This factor alone wipes out any savings in gasoline expense, considering 15k miles per year.
2. If you don't care about depreciation because you are going to keep your Prius forever, then you better think about how much it is going to cost to replace the batteries. "Prius batteries last forever; I will never have to replace them, and maintenance costs have been low!" Right. Sure. I believe it. NOT!
3. What about your time? Time is money, as they say. Accelerating at rates that give you 52 MPG, and driving slowly on the highway to maximize fuel efficiency will both increase the time you sit in your car. Is your time worth anything? Mine is. 2 - 3 minutes of my time every day, spent sitting in a Prius to maximize fuel efficiency is enough time to wipe out any fuel expense savings. Often when I find myself held up in traffic because of a slow driver, it is a Prius!
If you look at the total cost of ownership of a Prius compared to a Yaris, you will see that the Yaris has a lower cost, even though the gasoline expense is a little more than that of a Prius.
The Prius isn't for anyone who wants to save money. It is only for people who don't comprehend that there are expenses other than fuel.
The MSRP range you quoted for the Yaris seems accurate, but the correct range for the Prius is $24,000 - $29,805, not $19,737 - $24,016. There are stripped-down models, and there are also more expensive models.
The efficiency of new cars over older ones is moot if, as I have read, the emmissions over the existance of the vehicle is >90% in manufacture and recycling and 10% in use. It indicates that an older car kept in service for another 5, or even 10 years, saves a lot more than scrapping a 10y/o vehicle to replace it with even a hybrid. Also, with recharging a battery or hybrid vehicle, it only moves the emissions back to the power station.
Yes plants take CO2 and produce Oxigen, the KEY here is HOW MUCH and at what SPEED, the amount they use is the same no matter how much CO2 is in the environment and the speed at which they use it is also CONSTANT (or to say in a different way; dependent within narrow limits of the amounts of sun the receive, which can't be changed).
The only way to increase HOW MUCH CO2 gets converted is to INCREASE the AMOUNT OF PLANTS, unfortunately the net balance IN PLANET EARTH is that the NET AMOUNT OF PLANTS in the planet is DECREASING, the planet is being DEFORESTED at incresing speeds as depredatory human use of plants and resources increase and HUMAN PRODUCTION of CO2 and polution is INCREASING at such rate that ANY AMOUNT OF PLANTS is actually able to take those amounts of CO2.
Get the idea?
Is like the idea of a generator driven by an electric motor to produce energy that will drive the electric motor... the numbers DON'T ADD up.
Recently we had someone at PriusChat pose the same question: can an efficient engine compete with a Prius if everything else is the same?
It turns out Toyota has done the experiment with the "Prius c" and "Yaris". Comparing the 1.5L, automatic Prius c to the 1.5L, automatic Yaris:
53 MPG :: 32 MPG - City, Prius c to Yaris
46 MPG :: 35 MPG - Hwy, Prius c to Yaris
$19,737 - $24,016 :: $14,840 - $ 17,200 - Prius c to Yaris
Since 2004 when the battery modules and transaxle were redesigned, we're not seeing failures. In fact, salvage Prius are providing parts for the 2001-03 Prius which also continue to keep on running. I've got 150,000 miles on our first Prius and we're still getting 52 MPG. Since we put over 15,000 miles/yr on that car, it has been a very good deal with low maintenace (the engine is loafing) and we still haven't replaced brake pads or shoes.
Like any new technology, the Prius isn't for everyone ... just those who prefer to bank their fuel savings. For those who don't drive much, any car will do. But if you're driving more than 15,000 miles per year, the Prius can help make a car payment every year . . . even after the car is paid off.
One reason: the photosynthesis cycle doesn't remove CO2 permanently. It binds carbon with hydrogen (from water) to release O2. However, there are other processes that release carbon, consuming O2. Animals are one (eat carbohydrates, eliminate CO2). Microbes do it (composting, wetlands, etc.). Fire does it.
So, just planting greenery doesn't necessarily modify the amount of carbon in play. It takes also preventing the hydrocarbon from breaking down. Otherwise, it is just a wheel turning around, figuratively speaking.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
