Honda developing super-efficient hybrids

Honda is investigating ways of recapturing heat energy lost through a car’s exhaust to help generate electricity and power an electric motor for a new generation of ultra-efficient hybrid cars. Conventional internal combustion engines waste a lot of energy in creating heat, but by applying a ‘Rankine cycle,’ a process where hot exhaust gases are used to heat up a water reservoir and create steam to spin a turbine, electricity can be generated. This electricity can then be used to charge up an array of batteries and help power a hybrid-electric powertrain.

Engineers have been using a Honda Stream as their test vehicle, a compact crossover sold in Japan and parts of Europe powered by 2.0L direct-injection petrol four-cylinder. The car was fitted with a new cylinder head with insulated exhaust ports, an evaporator built into the catalytic converter, a high-pressure water reservoir plus a generator and condenser.

So Mike, you're "MidEngine"?

mike is indeed MudEngine (handle modified to reflect his muddled thoughts). some of his posts as midengine were overzealous i guess, so he got banned.

mike galoomph is indded, the Second Coming of MudEngine.

you may well be competent in logic from an mathematical perspective. but in your sad attempts at sociological "analysis" and judgments, you are a total FAILURE.

#1. you cannot classify whole cultures, to say nothing of nations, on the basis of religion. nations and cultures are composed of INDIVIDUALS, who vary widely.

#2. you think quoting the Bible authoritates your often racist and prejudiced statements. how would you like it if some Islamic person condemned your personal morality, and that of your nation and culture, and quoted out of the Koran to justify his wild statements? what YOU do is NO DIFFERENT.

#3. while people in the "hard sciences" may look down their noses at those in the "soft sciences" since the latter can not come up with clear cut, numeric measurements, that IS NOT a measure of superiority.
i have studied in BOTH arenas. the soft sciences, esp. psychology, is as complex as physics, and far more difficult to master in certain cases.

one could almost argue that the hard scientists go there because their minds do not have the FLEXIBILITY to handle concepts that cannot be quantified.

Why does it make any more sense in a hybrid than any other engine? Seems to me, all motors could benefit from this technology if it is fitted properly.

hydrogen still have a long way to go. the current method for hydrogen production is the century old electrolyzation (maybe a typo), which consumes more energy to electrolyze hydrogen than what they can produce.
the ideal method is to use controllable nuclear fusion, which create massive electricity, nearly non-radioactive waste, and hydrogen.

i don't think we will have the controllable nuclear fusion anytime soon. Even if we have a prototype , it will still take half a century to make it practical to use.

until that day, hybrid vehicle is still the best alternative for U.S.

i have a friend who is working at the local university on alternative energy systems.

they GAVE UP on hydrogen long ago. simply NO PROMISE at all. not only practically, but theoretically.

btw, check out the article in the current Popular Mechanix about alternative power in alaska. my friend met the author while she helped pick up the hydrolyzer his dept. was GETTING RID OF.

the ONLY basis for hydrogen EVER becoming a viable system, is if there is a source of EXTREMELY CHEAP electricity. which is why the hydrolyzer was given, gratis, to the project using geothermal energy.

there are still the immense problems of storage and infrastructure. hydrogen will likely NEVER be used for transportation.

cLUTZ is applying denial technology to improve his cars. Then he will hide it's inferiority by hiring famous people to dance around the car. He will then pay a magazine publisher to give it a title "Highest Initial Value"...then there will be a small disclaimer that once you drive off the lot and breaks, the initial value claims is then technically void.

It only has benefit to a Hybrid, since only Hybrids have batteries to store the generated energy, and then to use the engergy (electric motor). Regenerative braking is enough to recharge the battery in a non-hybrid.

Capture of the entropy (aka HEAT) caused by the explosive process is the next step in efficiency for the combustion engine.. Where 50-70% of the energy is use to make heat instead of motion.

Even with "hydrogen combustion" there is still heat genterated, so only the hydrogen fuel cell cars would NOT benefit..

I have a suspicion that Honda and BMW are having a secret affair. New Accord bimmer-like styling, upcoming Deutsch D-TEC…I’m just saying.

honda is arguably MORE ADVANCED than bmw in engine technology.

honda invented modern variable valve timing. bmw and everyone else was forced to come up with their own versions, just to stay competitive.

honda motorcycles have more advanced, and higher output engines than bmw bikes.

i will concede honda did stoop to jump on the bmw bandwagen, using the ugly kinky Hoffy c-pillar design. all THAT suggests is copying the WRONG answer from a classmate.
