I don't know if you guys have seen this, but they claim to have a working prototype and are taking orders for the first 300 conversions to make the Sky all electric. If it's true, they could easily do a Solstice too. It costs about $25k plus car. I personally think it's just another scam because there are no pictures on their website of this supposed prototype and just a link to how to order. However, if it's all true, it might be interesting. Here's there site:
