The hangar-like facility is packed with enormous pieces of equipment: transformers, generators and the odd huge aluminium sphere.
It is one of the few places in the UK where scientists can work with huge voltages at first-hand.
Electricity is taken straight from the mains, at the UK's standard 240 volts, but a towering impulse generator ramps it up to a massive two million volts - creating a voltage that can be used to see how lightning attaches to objects.
As the sun started to set last night here in Colliers Wood and the boys returned from their trek to Camden, we got the old barbeque out and had a right feast. Don't think I'll have to eat again for a week!
Inevitably the Salmiakkikossu (Finnish spirit made with the black stuff "salmiakki" and vodka like booze called "Koskenkorva" ) made an apperance but remembering what my hangover was like after the Midsummer party I wisely had only one shot.
Karelian Blonde, Toni (on the right) and Joni polished it off and we all decided to come inside as it was getting a bit nippy in the garden.
I wanted to crash out but as it happens our neighbour had her 50th birthday party and their stereo was on full blast in their garden until about 3.30 this morning.
I stuck some earplugs on and managed to get some sleep but the boys' bedroom window is directly above their garden so I don't think they had much kip.
The lads got sporty after eating with a game called Footbag.

Resident Lounge Lizard Gerald appeared from the bushes as soon as he could smell the sausages, as usual.
Fish and chips have gained the top spot in a list of the 50 things we love most about Britain.
The popular fried takeaway is loved more dearly than the Queen, who came second on the list.
The Royal Family collectively appears in the chart at no 10 and Prince Harry is nominated at no 44.
The poll of 7,000 Brits was conducted by Holiday Inn hotel chain.
Buckingham Palace is rated the nation's most loved building at no 11 and other popular locations include the Tower of London, Big Ben, Stonehenge, Camden Market and the seaside resort of Blackpool, all of which make the top 50.
Old-fashioned pubs, red phone boxes and cream teas all make the top ten, confirming that traditional notions of Britain's heritage are as popular today as ever.
The iconic Black cabs and the old Routemaster double-decker buses are highly regarded as well as several British cars, including the Aston Martin, the Mini Cooper and the Jaguar E-type.
Andrew Smith, spokesman for Holiday Inn said: "As a nation we are rightly patriotic. This list gives a fascinating insight into exactly what it means to be British - our food, history, Royalty, our many wonderful characters and all the fabulous places we love to visit."
"It's great to celebrate the things we love about our country. Over the last few years there's been a big surge in the numbers of people spending their holidays touring around this wonderful land - and this tells us why."

This is truly a case of "the beauty is in the eye of the beholder".
A one-eyed three legged Chinese crested dog called Gus (below) was crowned The World's Ugliest Dog on Saturday at the annual competition in Sonoma-Marin Fair in Northern California. The top prize is $1,000 (£510.)
Some critics have derided the contest for being little more than an animal freakshow, while supporters have claimed it goes a long way to champion pets that would otherwise go unregarded.
Indeed, many of the competitors have previously suffered neglect before being rescued from animal homes. Winner Gus lost an eye after a fight with a cat and had his leg amputated because of a tumour.
Our old strimmer gave up the ghost eariler in the spring so today when me and Tommi ventured to the local shopping centre I bought a new one and of course made him first of all carry it home and then do all the work!
We've been doing bits and pieces all week like painted the fence and gate in front of the house, mowed the lawn etc. and now we're just about to settle down to celebrate Midsummer.
It's the biggest annual holiday in Finland after Xmas. My friend Heidi is arriving soon, we're going to barbecue and have a traditional bonfire afterwards.
The spuds are doing well but...
...the bloody bastard slugs have eaten all but one of my sunflowers, exactly as last year!
My friend Tommi from Finland is visiting me at the moment with his brother Tuomo, who's never been to England before so we've done the touristy things today: London Eye (I didn't go as I've been five times already but the boys had a spin) and Madame Tussauds.
Met some famous folk there...
Me and Johnny Depp. Oh Johnny...
Me and Boris Becker. I never realised he is that tall! I'm 5'7, he is 6'3, apparently!
Me and my girl Madge.
John Travolta and me with Mr Cool, Samuel L Jackson.
Jennifer Lopez looked surprised to find Tommi's hand on her bottom!
