This is really good news – the company formed by Dr Robert Bussard, EMC2, has just been awarded more money to build another ‘Wiffleball’, called the WB-8.
There’s more details at Power and Control: WB-8 In The Works, including a very good primer on this particular brand of fusion at Bussard’s IEC Fusion Technology (Polywell Fusion) Explained.

Time lines for knowing whether this will work commercially – 18-24 months. If it does, then all bets are off….
