<p class=MsoPlainText>But as with most ‘alternative’ energy sources – there is
an infrastructure problem… What ‘gas-station’ is going to install an air
compressor with only one or two of these cars in an area? Same with other types
of compressed fuels (CNG, Hydrogen, etc…)… So not only do we have to try to make
something safe – but realistic. I have hopes for a lot of these alternatives –
may the best one win! <span style='font-family:Wingdings'>J</span><o:p></o:p></p>

<tt>> Part of the problem here is that lead acid batteries are very heavy

good </tt><br>

<tt>> real money pit.</tt><br>
<tt>></tt><br>
<tt>> As Adam said, for efficiency you really should have three phase AC </tt><br>
<tt>> motors (preferably running at about 440-600v) but the power inversion </tt><br>
<tt>> kills any efficiency. So it would take some real creativity to make a </tt><br>
<tt>> three phase motor work. I wonder if it'd be possible to create
the </tt><br>
<tt>> necessary input through selective switching of cells. I don't know how
</tt><br>
<tt>> easy or cheap it would be to buy enough super high power transistors
to </tt><br>
<tt>> do that though. Transistor switching through mosfet gates can be done </tt><br>
<tt>> very efficiently but there is an upper limit to the amount of current </tt><br>
<tt>> you can pass this way. It might work as you don't need so much current
</tt><br>
<tt>> when running 600v three phase. It would require substantial electrical
</tt><br>
<tt>> experience to pull off.</tt><br>
