Electrically Powered Ultralight Aircraft

The major problem is the weight of the batteries, still far heavier
than gasoline. Also the lithium polymer batteries used are still
quite expensive (over $10,000 for enough for a half hour flight) and
somewhat dangerous (sort them out and they can explode!)

Damn straight! No way am I going to strap a bunch of lithium polymer
batteries to my butt.

Some of the newer Lithium iron cells, maybe, but they also cost a LOT more.

Still, electric flight, like many have said, still have a way to go.

And as if we need more proof of this.

TOKYO: Japan's Toyota Motor Corp. will delay by one or two years the rollout
of new high-mileage hybrids with lithium-ion batteries because of safety
concerns, reported a newspaper.

Toyota's decision was prompted by worries that the batteries could overheat,
catch fire or even explode, the Wall Street Journal on Thursday reported in
its online edition, quoting unnamed Toyota executives.

Just saw where GM bought a battery company here in US that has
developed batteries that do not catch fire or expload like current
Lithium Polymer's.

GM expects to have a plug in auto on market at least two years before
Toyota can get their batteries sorted out and their auto on the
market.

GM on the cutting edge of anything is a little funny. And I'm sure Sony
didn't think their batteries would do this...

Is this the story you are talking about John? If so what is an "LG Chem
cell?"

GM doing this also kind of proves my point that the new battery technology
is coming from somewhere with a lot more money in play than the ultralight
and LSA market.

"LG" is Lucky Goldstar, a Korean conglomerate.

So it is just another version of a Li-Ion battery and not a "new"
technology?
