There are several videos of modified seam welding equipment being used to excite small aliquots of solid fuel mixture to stimulate hydrino formation with the release of considerable energy. Initially Dr. Mills planned to use magnetohydrodynamic generators to produce electricity from the supersonic charged plasma formed in the reaction, however there is now a video demonstrating use of solar cells to collect the light energy and using it to power LED lights. The light produced by the reaction is apparently 50,000 times brighter than sunlight, and is ideal for use with solar concentrator cells to produce electricity. The water-based solid fuel has gone through two iterations and the latest fuel produces visibly brighter reactions as shown in the videos.
There are also links to two new independent replications of an experiment to demonstrate excess heat production from a heated fuel mixture well in excess of any previously known chemistry.
