We The People Know That We need to get off of fossil fuel
You Have Seen Me Say This Before - And I will Continue To Do So
PEOPLE - Support the growth of Green Energy ( Power & Fuel ) - Call for Implementation of Green Energy power & fuel technology.
Demand a change over from fossil power & fuel.
Demand the end of fossil fuel subsidies - DEMAND THE SUBSIDIES BE SWITCHED OVER TO SUPPORTING THE GROWTH OF GREEN TECHNOLOGY/INDUSTRY.
Start in fossil fuel industry country - get those workers good paying green technology jobs - Make The Change-Over Now.
End the reason for strife here at home and also around the world.
Green Power and Fuel technology industry implementation and support for such - is a HUGE ISSUE FOR THE GOOD OF THE PEOPLE AND THE WORLD. ( Economy Prosperity PEACE HEALTH )
BTW - In case you were not aware - knocking out the use of fossil fuel - would also drive down the need for the military industrial complex and the needless loss of life around the world ( our lives and their lives ).
So fossil fuel and green tech are very central issues tied to the health of society ( USA & World) economic health - environmental health.
IMO - Liquid Hydrogen is Key to being clean in power generation and for providing transportation as well as heating and cooking FUEL
We can not take a wait and see attitude about our environment. I responded to another post about demanding electric cars - only I think we would be much further ahead of the game to switch over from fossil fuel use to using liquid hydrogen in all forms of transportation or work vehicle - anything that currently uses an internal combustion engine - even for powering generators for producing electricity.
I had run across a report on the use of liquid hydrogen for use in fueling airplanes/jets and figured that this would be used in a bottle storage/delivery system - the same as using bottled liquid propane or natural gas. The hang-up till now has always been the pursuit of a fuel cell - I mean WTF(?) why do we need to use a fuel cell if we can just use a bottle same as for propane? Gas stations already refill propane cylinders/bottles why the hell couldn't they do the same for liquid hydrogen? It is the same process.
As for the needed changes in the manufacturing of transportation - it would be absolutely minimal even to the point of upgrading most gasoline burners on the road today. There are already hybrid vehicles which use liquid propane as well as gasoline and all that is needed is a flick of a switch on the dashboard to switch from the propane to the gasoline tank and back again. It just requires an upgrade to the carburation and the mounting of a liquid hydrogen cylinder/bottle in the same manner as with the propane bottle. Diesel would be a bit tougher in that the oil would need a separate delivery to the mixing point going into the cylinders.
As Liquid Hydrogen production ramps up to meet the demand - gasoline can be removed from the process - it could perhaps be removed quicker by using a hybrid liquid propane ( or methane ? - don't need to frack for methane - just ferment garbage or plant material "leaves grass etc" waste - sewer gas is methane ) and liquid hydrogen set-up.
High volume liquid hydrogen storage and delivery already exists as "Air Products company" delivers or delivered to NASA what they needed for launches.
Liquid hydrogen stove/oven/furnace?????
Delivery could use the existing natural gas pipelines as well as residential ( individual dwelling supply tanks )????
Residential switch over could be addressed through the power utilities - sections could be targeted for upgrade - stove oven furnace upgrade kits to handle liquid hydrogen could be installed by the power utilities - cost for the kit and installation could be put on the monthly bill at say a payoff of 5.00 mnth for the upgrade.
Our Power Infrastructure ( generation & delivery ) is old and weak and needs an on-going upgrade/renewal anyway - Let's See That It Gets Done Right!
Excerpt: Other alternative fuels result in airplane performance penalties. For example, liquid hydrogen (LH2) not only presents very substantial airport infrastructure and airplane design issues, but because of the need for heavy fuel tanks, a short-range airplane would experience a 28 percent decrease in energy efficiency while on a 500-nautical-mile (nmi) mission. However, because airplanes need to carry much more fuel for a long range flight, and Liquid Hydrogen (LH2) fuel is quite lightweight the lighter takeoff weight of the airplane results in an energy efficiency loss of only 2 percent while on a 3,000-nm mission.
