Yes but exhaust gases can be cleaned and batteries can be nearly completely recycled.
Also there's the marketing of nuclear fuel for transport. Regardless of how safe it is people will see Chernobyl and Fukushima at the first mention of it.
The Thorium fuel is one of the most plentiful elements found on Earth. Smaller, neighborhood reactors are easily feasible, simplifying the grid. The reaction is also much more thorough than our current fission reactors, leaving significantly less spent waste that is much easier and safer to maintain.
For example, NYC per capita electrical demand went from just over 2,000 kWh to just under 8,000 kWh (with a pop increase from 7.781M to 8.214M). That's a lot of power, and solar/wind/wishing won't fill the demand.http://www.nae.edu/Publications/Brid...aResource.aspx
our current Nuclear infrastructure was built specifically because there was a military use for a small portion of the waste (PU-239). Thorium does not produce PU-239 as a byproduct, and thus is of no use to the military.
While Thorium isn't a "new improvement" in energy generation, it is an important option to review. There is significant potential in this technology, with very low risks when compared to hydroelectric, conventional uranium based fission, and hydrocarbon energy generation.
I finished my mechanical engineering degree about ten years ago. As an upperclassman I chose to focus on alternative fuels and advanced technology vehicles.
I will never forget what one of my professors once said in 2002: "Hydrogen is the fuel of the future, and always will be".
That was ten years ago and he's still correct as of now.
I think we may possibly make our way into sustainable biodiesel. Currently we have only a few ways to produce it, but it's not feasible due to the high amount of land/water it takes to farm the oil required. Algae/Microalgae has a high operational/capital for the amount of oil it yields when cultivated, but we are progressing to more efficient algae growing factors. So while technically not solar, we may still use the (free)sunlight to our advantage in basically growing our own biofuel.
That, and the fact that we have some pretty good mpg from current diesel engines while still operating within emissions laws, i think that it is a big possibility.
This is a great clip, but do watch the entire gashole doc if you can.
Growing switchgrass etc. on areas that currently can't be used for agriculture makes some sense, so do algae-based processes.
After incessant complaints from a to z, I am now calling all of my characters "special."
But it would require diesel engines of a sort, which I'm perfectly fine with.
POO POWER FTW!!!!!
Opting for unconventional business ideas has always been appealing. To be precise, coming with something out of the box have always grabbed attention. Same is the case with Japan’s ace toilet maker, Toto Ltd, as the company has come up with something different in its own domain. The Japanese firm recently unveiled an interesting poop-powered motorcycle in a Fujisawa showroom.
The motorcycle, to run on excrement, can actually travel as far as 300 kilometers with the tank fully loaded with animal waste. The motorcycle, being advertised as the maiden waste-powered vehicle, has been a project since 2009 and has been christened Toilet Bike Neo. The most interesting feature of the three-wheeler is the placement of the tank. The place of regular seat has been replaced with a toilet along with a huge paper roll at the back of it.
But if you’re thinking that the 250cc trike, Toilet Bike Neo, would run on its riders’ waste, my friend you certainly have mistaken. The machine simply runs on livestock waste or waste water. Talking to a few reporters in a Tokyo suburb, Toto Ltd’s spokesperson, Kenji Fujita confirmed it by saying,
“The biogas it uses as fuel is not made from human waste. It’s made from livestock waste and sewage.”
Now a question must have risen in your mind, why did Toto induced a toilet-derived seat then. Well! It’s just because of the prospective publicity that the company would gain that it has been featured.

"As anyone who has ever tinkered with an old BMW engine or looked out on to the wing of a jet can attest, pure response to engineering requirements can sometimes deliver just as much pleasure as a more intentionally aesthetic design process."
...you will start to realize just how difficult it will be unless one manufacturer coordinates with Better Place, and you can see that will be far into the future before we can make their "battery switching" model make sense. Of course, this is just my opinion, I'm sure many smarter people than me will look for ways to reduce the "friction" in the system.
