1W is enough for a cell phone, if you combined it with a capacitor for brief bursts at higher watts.

Now play a game for an hour...

Not all phones need to play games and gaming phones don't need to use this type of technology. I would love a phone that I don't need to charge and most people could benefit from one. And for the select few that like to play intensive games on it then they can get ones that would need to be charged.

Though I doubt this technology will be the answer to that want though.

Yeah especially with just 0.001% of the estimated workload (~10W when gaming, but even when standby 0.5W, 100uW are still just 0.02% of that...). Needs a lot more research...

You throttle the cpu with long heavy workloads, just like phones already do due to the significant thermal constraints of the form factor.

My phone uses 0.6W when idle and 1.2-2.5W while I'm using it. Peaks are 8W+. No way an internal reactor only can power a phone.

Edit: 0.3W when screen is off.
