$this->bbcode_second_pass_quote('BiGG', '[')b]I just don’t see how anybody can not be excited by fuel cells as they are our future and here already!
With every post you make, you just display ignorance and naivety. Fuel cells have been discussed
ad nauseam on this forum and their advantages and disadvantages debated many times
by people who have a helluva sight more knowledge in their little fingers than you appear to have within your cranium. I'll not repeat why you are so utterly wrong.
The following are two posts made in another forum, which respond well to the OP in this thread:
$this->bbcode_second_pass_quote('', 'R')ight, methanol is an insidious and dangerous cumulative toxin which
will destroy brain cells, with an initial predilection for the optic
nerve. It can be absorbed by ingestion, inhalation of the vapours or
through the skin (it is the fastest liquid for dermal uptake). It also
has a flash point of 12°C and explosive limits of between 6% and 36% in
air. You would need 99.9% pure methanol for fuel cell needs and this is
expensive and impossible to buy in some countries due to its toxicity
(special licence issued only to qualified chemists.
I extract from the J.T. Baker MSDS:

Potential Health Effects
----------------------------------
Inhalation:
A slight irritant to the mucous membranes. Toxic effects exerted upon
nervous system, particularly the optic nerve. Once absorbed into the
body, it is very slowly eliminated. Symptoms of overexposure may include
headache, drowsiness, nausea, vomiting, blurred vision, blindness, coma,
and death. A person may get better but then worse again up to 30 hours
later.
Ingestion:
Toxic. Symptoms parallel inhalation. Can intoxicate and cause blindness.
Usual fatal dose: 100-125 milliliters.
Skin Contact:
Methyl alcohol is a defatting agent and may cause skin to become dry and
cracked. Skin absorption can occur; symptoms may parallel inhalation
exposure.
Eye Contact:
Irritant. Continued exposure may cause eye lesions.
Chronic Exposure:
Marked impairment of vision has been reported. Repeated or prolonged
exposure may cause skin irritation.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired
liver or kidney function may be more susceptible to the effects of the
substance.
IATA CLASS:SUBSIDARY HAZARD CLASS IS POISONOUS SUBSTANCE.

if shaken up in a container, may create an explosive mix of air and vapours.
