Is energy on the order of 300MJ so cheap? You’d think that cutting it down to 150MJ would allow them to do more experiments.

300 megajoules is 83 kilowatt hours

a typical power price at trading hubs is US$40 per megawatt hour, though this varies considerably depending on many factors and is sometimes actually negative

a typical retail price is US$120 per megawatt hour

so this is about US$10 worth of electrical energy

300MJ ~= 83kWh which is like, $2000 in CA

I think you're out by some orders of magnitude. With the current energy issues in the UK it'd be under £100. Other things suggest in California it's more like 20 cents per kWh so were you thinking ~$20?

You're right of course, messing up my units again.
