| **Intresting quotes to dive into later: | | *[[Hydrogen Production]] |
| *** "hydrogen would fuel a fourth of the vehicle fleet in the industrialized countries by 2025"
| |
| *** "Turning wheels with electric motors has well-known advantages of torque, ruggedness, reliability, simplicity, controllability, quietness, and low cost. Heavy and costly batteries have limited battery-powered electric cars to small niche markets, although the miniature lithium batteries
| |
| now used in cellphones are severalfold better than the batteries used in electric cars. But California regulators’ initial focus on battery cars had a huge societal value because it greatly advanced
| |
| electric drivesystems. The only question is where to get the electricity. Hybrid-electric cars now
| |
| on the market from Honda and Toyota, and soon from virtually all automakers, make the electricity with onboard engine-generators, or recover it from braking. These “hybrid-electric” designs provide all the advantages of electric propulsion without the disadvantages of batteries.
| |
| Still better will be fuel cells — the most efficient (~50–70% from hydrogen to direct-current
| |
| electricity), clean, and reliable known way to make electricity from fuel. Nearly all significant
| |
| automakers now have major fuel-cell car development programs."
| |
| ****Lithium Ion Battery Development may have gone way farther than they predicted
| |
| *** "...However, the 2–3-fold efficiency advantage of the fuel cell, i.e., less
| |
| energy expended per mile, compared to a gasoline engine"
| |
| ****I feel most of the issues are brushed off via comparing fuel cells to gasoline engines, which is valid and fuel cells ARE GREAT, but this point is irrelevant with [[HICEs]] which may even add more inefficiency
| |
| *** "In general, the best way to get access to where you want to be is to be there already, via sensible | |
| land-use (spatial planning or its market equivalent — American communities would have a lot
| |
| less sprawl if their governments at all levels didn’t mandate and subsidize it)."
| |
| ****So true it hurts lol (also [[NUMTOT]] / [[New Urbanism]] has entered the chat)
| |
| ***A hydrogen-optimized internal-combustion engine can be ~30–50% more efficient than today’s gasoline engines — i.e., about as efficient as a diesel engine, but much cleaner. BMW even hopes to raise the peak fuel-to-output-shaft efficiency of new hydrogen internal-combustion engines to ~50%.Converting existing cars to hydrogen fueling, however, would capture a much smaller efficiency gain. Enthusiasts of such fuel-system retrofits have not convincingly explained how an internal-combustion-engine car could get a decent driving range from the hydrogen without using such a big hydrogen tank as to leave insufficient space for people and cargo.
| |
| ****This is my main concern for non fuel cell applications
