bio-diesel hybrid future

I still wonder about the programmed combustion engine, as in the Ford
Proco research. Diesel fuels still need to have a sufficient cetane
rating, which I understand takes careful refining. Existing spark
ignition engines take a high octane rating. Supposedly the proco
engine- a hybrid between the diesel and the SI engine, would run on a
wider cut- less refining- than either motor diesel fuels or gasoline.
Sounds like an ideal solution to me. It was basically a diesel cycle,
but had a spark plug to ignite the mixture rather than rely on CI.
Anyone have any idea on why it failed.

where will you get the light during ALL the 24 hours when the sun does not
shine?

The difficult part is getting the sun on it for 24 hours each day! ;-)
You might want to recompute with some more realistic daylight hours. Also
efficiency drops off a lot in morning and evening and I'm not sure your
"average" figures take that into account.

Agree

This is where solar really has potential.... ie.e home
heating methods

The earth is a huge dynamo. Need to figure out how to harvest the ionosphere...still solar but more electromagnetic than
photonic...

Wow

Didn't know all this

To what are you exactly replying?

Some energy storage? Maybe hydrogen?

I'm sorry to have to inform you that in this calculation already the
averages are taken as an assumption. Probably you are confused by the word
'peak power' (actually 2 words .
It means that if you have a solar panel that is able to generate a peak
power of 150 W at full sun, in The Netherlands such a panel produces,
averaged over one year, a continuous power of almost 15 W.

And if you want to nitpick about decimal numbers be my guest, but not with
me please, in that case please put 8 m^2 on your roof.

An option I have heard about that is basically solar is bioengineered
single cell organisms that "breath" hydrogen rather than methane (there
are lots of those already). A solar heated "pond" that is
transparent-covered to collect the hydrogen seems pretty green.
