You mean fusion? Take a look at ITER: International Thermonuclear
Experimental Reactor. It is far from reality, but it is not science
fiction either.

You can think what you want, but investment in batteries and fuel
cells have seen a huge growth in the last few years. If batteries have
been intensely developed for over a century and is very mature, all
these investors and their expectations must be pretty foolish.




And yet this happens and causes MASSIVE recalls.

Yeah, it is called a typo.

I'm aware of ITER and the fact that *IF* ITER is a success, you can
expect an operational fusion power plant no earlier than 2040, by
which time a good percentage of current posters, including myself,
will be long dead.

The point is that contrary to what some think, the science of electro
chemistry is mature and all the easy stuff has already been done.

Current, cutting edge, laboratory batteries are still an order of
magnitude short of being a practical general replacement for liquid
fueled engines.

A startling new invention may appear next week that changes all that,
but I wouldn't hold my breath waiting for it to happen.

In the mean time, you get increamental advances in the technology.

But not all batteries are equal.

I have a small radio controlled helicopter. It has full cyclic and
collective pitch controls, tail rotor, etc. It runs off a battery, and
this helicopter would have not been practical just 20 years ago. What
made it practical is the lithium polymer battery, and making the
electronics to control a small but very powerful brushless motor small
enough and light enough. Everything else could have been built 20 years
ago (the main rotor blades are wooden and the PPM receiver is old hat).

It took about 15 years for the LiPoly battery to go from the lab to a
widely available commercial technology. In the lab, they've increased
the LiPoly battery's energy density by an order of magnitude (so based
on past performance, it'll be 15-20 years before we get to see this in
the shops).

Yeah, new stuff gets invented all the time.

Thanks for the news flash, I didn't know that.

The point is electrochemistry is NOT a new field of science and
all the easy stuff has already been done.
