Existing backers can choose to upgrade to the Pebble Time Steel without losing their spot in the queue, but they'll have to wait a bit longer for their reward – Pebble Time Steel starts shipping in July, instead of May for the first crop of standard Pebble Time devices, and June for the current backer group. .
Instead of using huge fuel rods, the "pebble bed" reactor encases uranium — including the stable isotope Uranium 238 — in small graphite spheres.
