British inventor discovers the Holy Grail, well according to the i, anyway!
A ‘mad-man’ from Bishop’s Stortford isn’t always taken seriously, says Peter Dearman, but now his idea is becoming reality
In 25 years of reporting on the environment, I’ve become unshakably convinced in the seriousness and urgency of tackling climate change, but also rather dismayed that our successes in reducing greenhouse gases and promising scientific breakthroughs go largely unreported.
I’ve seen super plants that improve photo-synthesis, cows that belch less methane and next-gen solar panels. But there is one individual who deserves to be as famous in green-tech as Elon Musk for how his invention could help stop global warming.
His name is Peter Dearman and he lives in a semi-detached house in Bishops Stortford. Here, in his garage, he invented a motor that runs on air.
Meeting Dearman for my new BBC Radio 4 series, 39 Ways To Save The Planet, he tells me: “It all started when I was a teenager in the 60s looking at cars and realised that petrol was going to run out, so I started looking for an alternative.”
The “fuel” for the Dearman Engine is nitrogen, the gas that makes up 80 per cent of air. If it’s compressed into a liquid, opening a valve leads it to expand rapidly – by 700 times. This can drive a piston, just like exploding petrol vapour, but nothing is burned so no CO2 is emitted. It’s not powerful enough to drive a competitive car, but can generate electricity and more besides.
“I sat on this idea for 20 to 30 years, not being able to do anything with it, because nobody is going to pay any attention to someone in a shed,” Dearman admits. “A ‘mad-man’ from Bishop’s Stortford isn’t always taken seriously”.
A motor that runs on air! WOW!!
Except of course, it does not. Or to put it more accurately, it runs on compressed air, which in turn needs energy to compress it in the first place, a fact which the report later alludes to:
In other words, it does not generate electricity, it simply stores it, and in an inefficient way too. In other words, the process wastes energy.
I have written about Highview a couple of times, when Ambrose Evans-Pritchard hyped it as the answer to all of our problems. In reality, their 250 MWh energy storage facility is a drop in the ocean, in terms of the storage we need to cover intermittent renewable energy.
This article is written by Tom Heap, who is the Rural Affairs Correspondent for the BBC, and oft times contributor to Countryfile. One of his contributions to the latter was a flagrantly biased broadcast against fracking, which I took apart here.
Rubbish like this latest report is par for the course for him.
