Where did the $1 million USD per monthly burn rate come from? We should  also consider the $3 million USD for the existing and new prototypes that will be collected between the time it was announced and the end of the first half.

So how long would $8.9 USD last for? Potentially by the time the sale of  Denselight happens. But I  do  think they have additional  spending that is planned and clearly they have signaled the need for additional  funding before the sale is expected to  happen.
