YAY!!!!!!!! ...
YAY!!!!!!!! HYDROGEN IN 2020 I CANT BELIEVE I WILL? LIVE TO SEE IT!!!!!!!!!!!!!! OMYGASH wub wub wub wub

wat the hell is ...
wat the hell is windows? whistler 2419? i dont like your attitude...

China makes a LOT ...
China makes a LOT of? bad policy choices, that's for sure, but investing in molten salt reactors isn't one of them. Whether nuclear is renewable or not is a mute argument thanks to E=mc2. Nuclear will always be some millions of times more energy dense than any kinetic, thermal, solar, or chemical renewable. Nuclear's limit right now lies with bad choice of fuel (uranium) and bad reactor designs which drop conversion efficiencies below 1%. Thorium MSRs could get 90%+ efficiency

Be useful and give ...
Be useful and give me the link to Windows Whistler 2419 instead.?

.......no, not only ...
.......no, not only hydrogen. that has nothing to do with a large motor. look up the properties of an electrical motor and then you will understand. look for the graph of rpm and torque of an electric motor versus an internal? combustion engine.

Really!? Well then ...
Really!? Well then only Hydrogen can power such a large? motor.

yeah i get it. but ...
yeah i get it. but the? reactors you mentioned are also nuclear powered. i am personally in favor of nuclear, but many people and countries are currently debating its further use in the future. also, nuclear energy is not technically defined as a "renewable" energy source. i don't think it is at least. china is also achieving its 8% economic growth at the expense of the environment. the damage caused is equal to the money they made from the 8% increase. this is y i dont support china.

also, electric? ...
also, electric? motors have a larger useful torque band than any internal combustion engine currently known. so why do you not want an electric motor again?

My point is, ...
My point is, although biodiesels are better than petrodiesels, they're not good enough of an answer to our? problems, especially when they threaten food security and still support global warming to an unacceptable extent. We have far, far cleaner and more renewable sources of energy at our disposal already: Molten salt reactors (like the ones China is rapidly developping) could provide compact and ultra-clean electricity to power a battery-based economy for instance.

First off, hydrogen ...
First off, hydrogen rises very quickly and burns upwards making explosions IMPOSSIBLE, while diesels tend to hug the ground and don't disperse safely. Second off, ALL motors produce torque. Finally, stop reading? Biodieselforums IMMEDIATELY. It's bulls**t. Alkyl esters are NOT less toxic than table salt, otherwise they would not be labelled as environmentally toxic and dangerous to aquatic ecologies.

I wasn't talking ...
I wasn't talking about biodiesels,? I was talking about methanol. Last I heard biodiesels are alkyl esters, not alcohols.

well, technically ...
well, technically you aren't burning the hydrogen,? but i get it

omg really? ...
omg really? gasoline and diesel are also EXTREMELY carcinogenic. where? are you going with this? besides, alcohol burning engines burn much cleaner than ordinary gasoline or diesel engines. the last line you wrote is true though.

the first line you ...
the first line you wrote is a pure? lie. look up the properties of hydrogen. an explosion is highly unlikely, not to mention hydrogen burns at a much lower temperature.

that's a moronic ...
that's a moronic comment, global warming is 10X more of a big deal to? other organism other than ourselves. As of now there is a mass extinction going on.

global warming ...
global warming isn't a big deal well for the other living things it's great just not for us.....we are likely? only going to use gas powered cars for about 20 years :/ after that not so much the oil will be used for making plastic and such

Methane can be ...
Methane can be obtained from biogas. When methanol is reacted with vegetable oil in the presence of sodium hydroxide (caustic soda) the reactants lose ALL their chemical properties. Thus biodiesel is less toxic than? table salt and as volatile as diesel.

But if you? were to ...
But if you? were to get into an accident, the results would be horrendous with hydrogen. And once again, waste oil can be used to produce biodiesel. And I want a torque diesel motor pulling me rather than an electric motor. Biodiesel does not emit soot, the black smoke from regular diesel. Only methanol and little caustic soda is used to react it. But the biodiesel is less toxic than table salt and as volatile as diesel!

When chemically ...
When chemically reacted, biodiesel is less toxic than table? salt and as volatile as diesel. Learn something about reactions first.

This is not true ...
This is not true anymore. One of the Toyota SUV prototypes gets over? 400 miles to a tank of hydrogen. I believe it's there gen. 3 model. The price will definitely go down in the future.

Methanol is much ...
Methanol is much worse than almost any fossil fuel, except maybe Methane which doubles as a very bad greenhouse gas by itself. In addition, methanol is a? carcinogen and is quite toxic, not something you want to spill at the pump. Availability is also dependant on availability of agricultural land, which incidentally isn't all that available.

Production of the ...
Production of the stuff has reduced food agriculture and is increasing the rate of deforestation worldwide. This is pretty significant both environmentally and economically. The only advantage is that, counting the production, biodiesel produces less CO2 than regular diesel. However, it's only a 50% reduction, and deforestation? can ultimately cancel out the gains made in CO2 capture when producing. Hydrogen can be produced from compact and clean sources of electricity, and burns clean.

Alcohol for ...
Alcohol for Methanol? is much more than available!

No, because it can ...
No, because it can be produced from waste cooking oil. It's much better than these things. Methane can be obtained from biogas.The process of producing caustic soda as a catalyst involves seawater? and calcium, which are all widely available.

Hydrogen? would ...
Hydrogen? would almost definitely need to be produced using electricity from plants. Producing the hydrogen isn't really the problem though, we already have extremely energy-dense, clean, and much safer ways of producing electricity that have recently resurfaced (just google LFTR, China already picked them up). The biggest issues right now are related to hydrogen storage. A research group at my university is working on cheap, high hydrogen density solids, but it'll take a while still.

It's actually ...
It's actually worse? for the environment.

not to? mention ...
not to? mention that EVs require electricity that is mostly produced from coal-fired power plants
