This things has 34% efficiency, Toyota is doing 38% with there latest Prius, and above 40% for the next generation models. If you want drop in why not go with a microturbine? Sure it would be less efficient at around 25-28%, but it will be lighter, won't need a cooling system, and could run on any thing from biodiesel, ethanol, gasoline, natural gas, hydrogen, etc, etc.
Still haven't heard anything about a charging road, lay some cables in the road, run high frequency current through it and electric cars could be powered on the drive.
Roger Pham, Electrics and Biofuels are already more developed and more economical than hydrogen, we should not waste time and money on hydrogen.
Sort of over-kill, if your going to using it primarily in electric your hauling around that huge diesel engine, I think they could get by with shrinking the batter blow 3 KWh and just making a hybrid. At 124 mpg what does it need to be a plug-in hybrid for?
Look the efficiency of electrolysis is at theoretical maximum at 75%, 85% for steam reforming and 75% for fuel cells (worse still is that PEM fuel cells will never do better then 60%), Many lithium chemistry batteries are already doing 95% efficiency charge/discharge cycles. Add in the needed inefficiencies of compressing hydrogen, and piping hydrogen, and its physically impossible for hydrogen economy to ever as efficient as a battery economy. Next there the already existing electric grid verse non-existent hydrogen piping and production capability. With the minor modifications to the existing grid and utilization of off peak power we could power 70-80% of cars electrically without a single new power plant, with hydrogen we would have to make all these steam reformers, electrolysis plants and pipelines. Hydrogen is a pain to store, it present safety problems equal to or worse then gasoline. We could make metal-air flow cell batteries with rapid fueling abilities and great range, with a paste fuel that is incombustible, safe and energy dense and uses relatively cheap materials like zinc or aluminum.
Where does the hydrogen come from, what will be the loss rate of the Rhodium salts? I looks nice, single step processes, but I'm not holding high hopes for a good EROEI ratio.
No the efficiency improvement is minor by their own emission, and many of the performance increase are purely hypothetical. If BEV or some other electric propulsion power plant is the future then going back to parallel hybrids is a waste of time and money on their part.
Considering its got 1 engine, 2 electric motors, 3 clutches, planetary gears and a huge battery pack its not exactly as simple as a 6 speed transmission on an engine. My problem with this is GM's broken promise of serial hybrid frame for future power plants.
The 300 hp total is only theoretical and not true in acceleration considering that the engine does not directly engage until the car is already going at high speed. We were hoping for a complexity REDUCTION, not at par with. A system as promised by GM that could interchange with other power source options.
Or they could have gone with an Atkinson cycle engine and not added all this extra complexity. If you think about GM's previous claims of wanting to be able to swap in different power sources (fuel cells, turbines, etc) than adding in a parallel hybrid system makes no sense!
Thermal depolymerization has been in development for decades, nothing sketchy about it.
As long as they can keep the installation prices low and efficiency high I'm all for it. No forgetting about plugging it in.
This is crazy, unless this is to boost output of fermentation products from sugar containing biomass it makes no sense to convert fats to fermentation products for fuel when the fats could much more efficiently be converted to biodiesel or synthetic petroleum.
To late for preventative mode, economies simply don't change overnight and we needed them to change 30 years ago! I'm all for reducing CO2 emissions but that realisitcally can only happen at a slow rate, aerosols on the other hand can act as a temporary fix.
I'm all for electrified ground transport but you can't run jets on electricity.
I like the response about how "this battery is not needed" like back in the 80's: "What the hell would we ever need more then 64k bytes?" True we can start penetrating the market with EVs todays, but these batteries (or batteries of this kind of performance) is going to allow EVs to dominate the market.
Unconventional oil reserves will only be viable at high oil prices, thus peak oil is about the end of cheap oil, heck at $4 a gallon of gasoline it becomes profitable to make gasoline from coal via gasification and F-T synthesis. Obviously Unconventional oil will have to compete against biofuels and electrics which will allow cleaner and perhaps cheaper alternatives, economics will thus push for alternative energy on it own.
Great, but how do they plan to mass produce this stuff cheaply?
Exactly, fuel prices are the biggest mover here, all we need in insanely high fuel prices to make EVs economical.
Climate changes denialist think our problems are just global warming (or lack off), our problems are much bigger than just global warming! No ones is going to care about global warming when oil hits $200 and beyond a barrel because there is not enough being produced to match world demand. Everyone going to start thinking about clean technologies not to be environmentally friendly but to try to bring down the cost of energy by bringing new sources to market and being more efficient with what we have.
The problems peak oil as well as peak lithium raise is not that oil or lithium or other resources will run out its that the price of mining them will rise to economically damaging levels. We could mine sea water of lithium but at what cost per gram of lithium?
I would not say IMA is inferior: for long distance driving it has superior efficiency to Toyota's synergy drive.
Why not other metals like zinc, aluminum or magnesium, these metals are cheaper? Why not a metal nano-particle paste flow cell for easy refueling and recharging?
Exactly what oil price did these people use? $75? Lets see the market penetration rate at $200 a barrel.
