I saw data from a study by the California Air Resources Board that indicated
that most were not using EV mode on hybrids very often - most never even
charged it. They bought it to get the rebates.
That being said, a friend at an OEM said that their data showed the opposite.

I feel it's a shame that Chevy stopped making Volts just when they were getting
good.
The 2nd Gen volts had an EPA rated battery only range of 53 miles. My wife is
the primary driver, and because the majority of her driving is at speeds under
50mph, the GOM typically displays an EV range of

The difference is in the Chevy Volt, just like the Prius and other similar
hybrids, they use a power-split device to directly connect the ICE to the
wheels. Obviously this was chosen because unlike the series hybrid, there
are less conversion stages before the power meets
Same here. I'm pretty sure I have had only one fail. Everything in the
house is LED except the bulbs in the attic (not worth the expense to
wholesale replace about 15 bulbs that are used maybe 4 hours per year).
I started converting to LED about a decade ago and had everything

Seems to me that most free piston engines operate as 2-cycle, so they don't
have any moving valves, just ports that are exposed or closed by the moving
piston. However, I suspect you could improve efficiency by using moveable
valves
In the past I've thought about trying to build a closed

Actually, I've had two fail, but the second one was a DIY assembly of a ring of

Chevy used to sell a very similar vehicle. I normally have one parked in the
driveway, but my wife drove it to work today.
